glibc installs some bash-scripts, but uses the path to the buildtool

In C, the proper syntax for a bit-wise OR is a single '|', not two.
It worked so far because all was well:

- R_OK||X_OK == 1

-> access( file, R_OK||X_OK ) worked
- inicidentally, the file we searched for also had the r-bit set,
but we were not testing that in fact.
Accept a local tarball name as the source of the Linux kernel headers,

To build the libstdc++ library, the compiler requires the C library. In
case we build for non-baremetal, this is normally handled by the final
step, later.
But in the case of bare-metal, we never go through the final step (because
it does not work, and it seems complex enough to make it work), so the
baremetal compilers are issued out of the core step.
A few facts:
- building the C library requires a proper core compiler
- core compiler is issued from one of the core passes
- the C library is required to build libstdc++
- newlib is only built for baremetal
- in bare metal, the final compiler is issued from one of the core passes
So we need to build the C library between core pass 1 and core pass 2.
The only place is eithe libc_headers() or libc_start_files(). The most
pertinent seems to be libc_start_files().
So we build newlib from libc_start_files(), and leave libc() empty.

Instead of looking again at previously handled ELF files, recursively
resolve every ELf files.
Also, in case there are a whole lot of files (more than the shell can
accept as arguments list, or creating a command line longer than the
shell can cope with), use a temporary file with the list of files
to search for missing dependencies.

- fix help text
- use an absolute path for sysroot
- replace "echo" with "printf"
- replace "stat -c '%i'" with "ls -1id"
- replace "pushd / popd" with "cd / cd -"
- remove superfluous break
- bail out if required lib not found, except if forced
If a list-file is used, then each library in the file will be handled
twice (not a real issue, as the second iteration will find the library
already present, just avoid doing the job twice).
This fixes two problems:
- the sysroot might be in a sub-directory (think SYSROOT_DIR_PREFIX)
- it is not needed to have the target tuple to properly detect the sysroot
and the required tools
As a side effect, this script is now no longer dependent on the target
tuple, and in the future, we might be able to share it across many
toolchains (when/if we can install all of them in the same place).
Add a new command line option, "-r", which allows the user to specify
an alternate sysroot location to copy libraries from. This is useful
when using the toolchain in combination with a separate root filesystem,
or when working with multiple different root filesystems.

The Debian server returns a friendly 404-page that is

it the extension to retrieve.
From this version of ltrace the maintainer has removed support for
GNU Autotools, so the patch sets needed to be reworked.
Included is the latest Debian patch, by the Debian ltrace maintainer
Juan Cespedes <cespedes@debian.org>, the OpenEmbedded patches for cross
compiling, by Khem Raj <raj.khem@gmail.com> and a further set of patches
by Joachim Nilsson <jocke@vmlinux.org> for crosstool-NG.
Using this: tar cf - -C "/some/place" |tar xf - -C "/some/other/place"
to copy a directory to another place does not properly fail (when it does).
Using this instead: cp -av "/some/place" "/some/other/place"
makes it easy to see why and how it failed.
Impacted:
libc/uClibc
debug/ltrace
tools/sstrip
scripts/populate
In case the remote file does not exist (and probably for some
other reasons as well), aria2 nonetheless creates an empty file
(or not empty for some other reasons).
The solution is to delete the file whenever aria2 fails.
aria2 is a powerfull downloader that is capable of chunking and
parallel retrieval.
Due to li;itations in crosstool-NG retrieval facilities, it's not possible
to take fully advantage of aria2. It might happen that, in the future,
those limitations get lifted away, so we can take use features such as
parallel downloading from more than one server at the same time. For now,
it should still speed up downloads thanks to parallel downloading of chunks.
The user shall provide a directory to install the toolchain into.
If he/she does not, this is an error, and shall be detected properly,
rather than relying on failure down the road.

Don't select unneeded config knobs. Don't select non-existing config knobs.
Use the "no patch" config knob, instead of pointing to an non-exiting local
patch dir. Simplify the tuple-related scripts. Update the samples.
When renumbering patches, the original patches get removed and replaced
with the new ones. This can be annoying to loose the original patches.
Fix this by putting the new patchs in a directory of their own.
Add config option to build wtarget code with THUMB interworking.
This is used to build the C library as well as all other code
that runs on the target.
The newlib "team" rolls new releases about once a year (december).
This is quite a long time between releases, in case code was fixed.
So, allow user to use a CVS snapshot to benefit early from fixes
and enhancements to newlib.
Some projects' module (eg. newlib) are checked-out into a sudirectory
rather than into their own directory. Handle this case in the CT_GetCVS
function.
newlib handles the build/host/target a bit differently as one would expect:
build : not used
host : the nachine that builds newlib
target : the machine on which newlib will run
Some patchsets have superfluous members in their names (eg. the ones coming
from Gentoo), so it can come in handy to pass a sed RE to strip them out of
the final patch name.
Also add a 'fake' mode, where the command will only be printed and not
executed, so we can check beforehand if the rename will be OK.
ncurses is built solely for the sake of building a native gdb.
The user should not rely on this library to build his/her userland,
but should rather build his/her own. So we remove it from the
sysroot after we successfully build the native gdb.
The option to retrieve snapshots is already handled by
the generic 'specific date' and 'use latest' entries.
No need for a special case, as there's no code for it.
For CLooG/PPL 0.15.3, the directory name was simply cloog-ppl.
For any later versions, the driectory name does have the version, such as
cloog-ppl-0.15.4.

Add the WRAPPER_NEEDED silent config option, that can be selected by
components that require it (companion libs so far).
Rely on this config option when deciding to install the wrapper,
instead of checking GMP/MPFR or PPL/CLoog/MPC.
Add an initial wrapper:
- find the realpath of the tool being called
- add the '.' in front of the tool name
- add the '/lib' dir to the base dir of the tool
- set and export LD_LIBRARY_PATH
- execve the real tool
Downoading a non-existing file from sourceforge gives you a "200 OK"
and an index.html. As we try to retrieve a .tar.bz2 first, and duma
is bundled in a .tar.gz, we won't get appropriate content, so
just force the extension to avoid the problem.
Thanks to Ingmar Schraub <is@eseco.de> for pointing out the issue.
During the conversion to using bash arrays, the glibc build script
was improperly converted, and contains an incorrect variable
assignment to the config_options array.
For every components where it makes sense, use bash arrays (instead
of a string with space-separated values) to store the options pased
to ./configure.
Rewrite part of the code to better match the rest.
Most notably, rewrite handling of:
if [ ... ] && [ ... ]
to:
if [ ... -a ... ]
This has the positive side effect of calling "[" only once, although
"[" is probably a shell built-in.
To test for existing files, use "[ -f blabla ]", not "[ -a blabla ]"
Checking for a file exsitence with "-a" is a bashism.
Althoug we _are_ using bash, it's disturbing as it can be misread as
the 'and' operator. Fix by using "-f".
The tmul test uses a compiled-in input file in $(srcdir).
The problem is that the Makefile passes it unquoted. The C code
tries to stringify it using clever macros, which may *usually* work.
In my case the source directory was named:
.../toolchain-powerpc-e500v2-linux-gnuspe-1.0-2.fc10/.../tests
And guess what? During testing I found out the program fails because
it tries to open:
.../toolchain-powerpc-e500v2-1-gnuspe-1.0-2.fc10/.../tests
Yes, CPP tokenized the macro before stringifying it and not surprisingly
the 'linux' part was converted to 1.
[on Fedora-10: cpp (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7)]
So the attached patch simplify the macros and pass the path as string
from the Makefile.
In case the shell the user wants to use as CONFIG_SHELL is located in a
weird place (eg. /opt/bash/bin/bash), or is weirdly named (eg. bash-4),
let the user enter the patch to the shell.
The wrapper script placed around the target binaries when
using the companion libraries does not work for symbolic links

Spaces are evil in paths. Print the path that contains a sapce.
Don't print computed paths, as they'rebased on provided paths,

Fix detecting src == dst.

Also change echo to printf, get rid of 'echo -n', which is
highly non-portable.

Initial patch by Dmitry PLOTNIKOV: http://sourceware.org/ml/crossgcc/2009-03/msg00053.html
It [the toolchain] uses current ct-ng (nightly snapshot 20090324, latest
release 1.3.2 work also), glibc 2.9 (from CVS), binutils 2.19 and latest
snapshot of GCC 4.4.0 (as of March 20, 2009).
We have successfully built linux kernel 2.6.29 and a lot of other stuff
with this toolchain.
Here's the patch that adds GCC 4.4.0 to the ct-ng menu and enables it to
download a 4.4.0 snapshot from ftp.
Patch was adpated by me, mostly to better fit the configuration layout.

Seems ncurses 5.7 need build host stage for tic step; if use host tic
(ubuntu) the build process hang in the below step.
So I guess need to build ncurses host stage to build new tic
and provided a patch to that efect.
And in fact, we do need "tic" to run on the _build_ system to properly
generate the terminfo database.
Note: this is fully functional, but still requires a litle bit of
tweaking so that ${CT_BUILD}-gcc gets used instead of plain gcc.
But that's a minor problem for now...

The glibc.sh script doesn't handle the glibc versions with

have attached a small patch for that. Instead of looking

an underscore, but that didn't work like I wanted (probably
because I did something wrong).

- symlink all lib64/ dirs to the corresponding lib/ dir
Also, prevent gcc from installing some of its target libs outside of the sys-root, in the first place.
Thanks to Laurent DUFRECHOU for reporting the bug and testing the fix.

Simplify CT_DoExecLog: it does not support affectations prior to the command, anyway.

Turned out that none could use GMP and MPFR as the config option changed its name, but the change was not propagated to all users.

Get rid of this by using printf(1) with no trailing new-line (\n).

add a config knob to configure the native gdb to use or not to use GMP and
MPFR; _this_config_knob_ will force building the target GMP and MPFR only if
turned on.

- some (presumably 'old') versions have libduma.so.0.0, while others (presumably 'newer') have libduma.so.0.0.0
- don't build the libraries multiple times, do it in one pass
- install a custom LD_PRELOAD wrapper

It is similar to CT_DoLog, but instead of printing its arguments, it uses them as a command, and logs the output of that command.

It seems to be helping gcc somewhat into telling the correct endianness to ld that sticks with little endian even when the target is big (eg armeb-unknown-linux-uclibcgnueabi).
There's still work to do, especially finish the gcc part that is not in this commit.

Some (most) of the sites we use toretrieve tarballs have http equivallent for the ftp service. Use http as a failover.
There's no solution for those sites that do not have such an http equivalent.

Consider the proxy has to be in a 'local' network. It means it is directly
reachable by the local machine, even if the local machine has to hop through
one or more gates to reach the proxy (often the case in enterprise networks
where class A 10.0.0.0/8 is in fact sub-divided into smaller networks, each
one of them in a different location, eg. 10.1.0.0/16 in a place, while
10.2.0.0/16 would be on the other side of the world). Not being in the same
subnet does not mean the proxy is not available.
So we will build a mask with at most high bits set, which defines a network
that has both the local machine and the proxy. Because a machine may have
more than one interface, build a mask for each of them, removing 127.0.0.1
which is added automagically by tsocks, and removing duplicate masks.
If all of this does not work, then it means the local machine can NOT in fact
reach the proxy, which in turn means the user mis-configured something (most
probably a typo...).

- a machine may well be able to reach the proxy, even if it is not on the same sub-net(s) as the machine itself (absolutely legitimate)
- tsocks.conf needs a list of so-called 'local' networks that can be reached without the need for a SOCKS connection
- SOCKS proxies are expected to be in 'local' networks
- there is absolutely NO way to tell what networks are local, besides the sub-net(s) the machine is in
Therefore, appropriate configuration of SOCKS 4/5 configuration is really complex, and attempts to correctly overcome this issue are doomed.

Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...
So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.
Homogenise the references to crosstool-NG:
- the project is named "crosstool-NG"
- the front-end is named "ct-ng"
- don't use shortcuts (such as "ct-ng" to stand for "crosstool-NG")
Default action is to print help.
Don't speak of make rules when dumping help, just speak of actions.
- revert sample dumping to not show the components versions;
docs/overview.txt:
- reorder docs/overview.txt so that configuring comes before running,
- tell about regtest;
Makefile:
config/global.in:
- point to docs/overview.txt for the list of steps;
- when not compiling NPTL, the shared core C compiler does not exist,
- PATH arranges for the shared core C compiler to be found before the static one, so no need to force it.
If you select to debug ct-ng, then you have two new options:
- DEBUG_CT_PAUSE_STEPS : pause between every steps,
- DEBUG_CT_SAVE_STEPS : save state between every steps.
To restart a saved state, just set the RESTART make variable when calling make:
- make RESTART=<step_name>
- pipe size in Linux is only 8*512=4096 bytes
- pipe size is not setable
- when the feeding process spits out data faster than the eating
process can read it, then the feeding process stalls after 4KiB
of data sent to the pipe
- for us, the progress bar would spawn a sub-shell every line,
and the sub-shell would in turn spawn a 'date' command.
Which was sloooww as hell, and would cause some kind of a
starvation: the pipe was full most of the time, and the
feeding process was stalled all this time.
Now, we use internal variables and a little hack based onan offset
to determine the elapsed time. Much faster this way, but still
CPU-intensive.
- associated patch set
- update the munging function to accomodate the new config variables
libfloat version was missing from the previous commit... :-(
Better handle the case where the sample directory already exist but isn't under revision control, and in case the destination file doesn't exist in the sample directory.
Add a uClibc-0.9.29 patch directory with one patch (from me!).
Update the armeb-unknown-linux-uclibc sample to uClibc-0.9.29.
Some eyecandy in the gdb build process.
- add a framework to easily add new ones
- add gdb as a first debug facility
- add patches for gdb
After the kernel checked its installed headers, clean up the mess of .checked.* files.
Reorder scripts/crosstool.sh:
- dump the configuration early
- renice early
- get info about build system early, when setting up the environment
- when in cross or native, the host tools are those of the build system, and only in this case
- elapsed time calculations moved to scripts/functions
Remove handling of the color: it's gone once and for all.
Update tools/addToolVersion.sh:
- handle debug facilities
- commonalise some code
- remove dead tools (cygwin, tcc)
Point to my address for bug reports.
- the tarball directory is considered as a local copy, and tarballs are copied to a working area,
- the sources and build directories (CT_SRC_DIR and CT_BUILD_DIR) are now computed, and no longer an option,
- the build dir has been renamed from 'build' to 'targets'.
That should ease preparing a tarball of the resulting target.
- use ports addon even when installing headers,
- use optimisation (-O) when installing headers, to avoid unnecessary warnings (thanks Robert P. J. DAY for pointing this out!),
- lowest kernel version to use is only X.Y.Z, not X.Y.Z.T,
- a bit of preparations for NPTL (RSN I hope),
- fix fixing the linker scripts (changing the backup file is kind of useless and stupid);
Shut uClibc finish step: there really is nothing to do;
Add a patch for glibc-2.3.6 weak aliases handling on some archs (ARM and ALPHA at least);
Did not catch the make errors: fixed the pattern matching in scripts/functions;
Introduce a new log level, ALL:
- send components' build messages there,
- DEBUG log level is destined only for crosstool-NG debug messages,
- migrate sub-actions to use appropriate log levels;
Update the armeb-unknown-linux-gnu sample:
- it builds!
- uses gcc-4.0.4 and glibc-2.3.6,
- updated to latest config options set.
Although we no longer need the kernel config file, we now need to specify the kernel source directory when installing headers.
Re-order components downloading to match build order.
Fix the saveSample.sh script in case the referenced files are the same as the destination files.
- reorder most of the environment setup,
- geting, extracting and patching are now components' sub-actions,
- save the current config as a sample to be used as a pre-configured target.
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(
