43c303c946 libc/*.sh: handle combinations of multilib root/dir.
Install startfiles for libc variants into the most specific combination
(suffixed sysroot, if applicable + suffixed multi-os dir, if
applicable). Install headers once in every suffixed sysroot (although it
seems that GCC picks up headers from top-level sysroot, GCC manual
claims that sysroot suffix affects headers search path).

In uClibc, this requires a better sanitization of the directory: it
creates symlinks from {sysroot}/usr/lib/{multi_os_dir} to
{sysroot}/lib/{multi_os_dir} and to do so, it counts the number of path
components in the libdir. This breaks if one of such components is `..'
- symlinks contain an extra `../..' then. Since such sanitization had to
be implemented anyway, use it in other places to print more sensible
directory names.

Also, fix the description of configure --host/--target per musl's
configure help message (and its actual code).

82072d0cbc multilib: Determine which options may pass through.
On some arches (e.g. MIPS) the options like -mabi do not work if
specified more than once (see the comment in 100-gcc.sh). Therefore,
we need to determine which of the options produced by <arch>.sh can
be passed to multilib builds and which must be removed (i.e., which
options vary among the multilibs).

This presents a chicken-and-egg problem. GCC developers, in their
infinite wisdom, do not allow arbitrary multilib specification to be
supplied to GCC's configure. Instead, the target (and sometimes some
extra options) determine the set of multilibs - which may include
different CPUs, different ABIs, different endianness, different FPUs,
different floating-point ABIs, ... That is, we don't know which parts
vary until we build GCC and ask it.

So, the solution implemented here is:
- For multilib builds, start with empty CT_ARCH_TARGET_CFLAGS/LDFLAGS.
- For multilib builds, require core pass 1. Pass 1 does not build any
  target binaries, so at that point, our target options have not been
  used yet.
- Provide an API to modify the environment variables for the steps that
  follow the current one.
- As a part of multilib-related housekeeping, determine the variable
  part of multilibs and filter out these options; pass the rest into
  CT_TARGET_CFLAGS/LDFLAGS.

This still does not handle extra dependencies between GCC options (like
-ma implying -mcpu=X -mtune=Y, etc.) but I feel that would complicate
matters too much. Let's leave this until there's a compelling case for
it.

Also, query GCC's sysroot suffix for targets that use it (SuperH,
for example) - the default multilib may not work if the command line
specifies the default option explicitly (%sysroot_suffix_spec is not
aware of multilib defaults).

27fed7e5f0 crosstool-NG.sh.in: Don't make lots of symlinks to lib folder
For 4 different folders:

${CT_PREFIX_DIR}
${CT_SYSROOT_DIR}
${CT_SYSROOT_DIR}/usr
${CT_PREFIX_DIR}/${CT_TARGET}

.. symlinks from 'lib32' and 'lib64' to 'lib' were created.
This was untidy and incorrect for multilib (the bitness of
the libraries in 'lib32' and 'lib64' will not be the same)
We can not know which folders this toolchain configuration
will require at this time so let them be created on-demand
instead.

Changed by Alexey Neyman: original change removed too much; we
still need to create the default directories because the os
directories are based off them (e.g. `lib/../lib64').

62d357d3c0 Unbreak static cross-gdb.
GDB's configure mishandles the libexpat.{so,a} libraries when it is
given -static in CFLAGS AND --with-libexpat-prefix in configure's args:
it checks for <prefix>/lib/libexpat.so and finding that, attempts to
link it as `gcc -static .. conftest.c <prefix>/lib/libexpat.so`; this
obviously fails (.so cannot be statically linked), so configure assumes
libexpat is unusable. Thus, --with-libexpat-prefix is dangerous and
should be avoided; instead, configure should find the libraries via the
supplied CC/LD definitions.

We check for apps:

* make
* sed
* grep
* awk
* libtool/libtoolize
* install
* patch

...during configure. Our scripts should be consistent about using the

Of course, we do hard-link these tools in buildtools, but that should be
a backup for the components we are building. Our scripts should always

10e1579799 scripts/crosstool-NG.sh.in: patch regex to work with BSD grep
BSD grep does not interpret a null alteration. It complains about an
empty sub-expression, e.g.:

$ grep --version && grep -E '^(# |)CT_' .config
grep (BSD grep) 2.5.1-FreeBSD
grep: empty (sub)expression

This patch replaces the null alteration with a zero or once quantifier
which works with both BSD & GNU grep.

$ grep --version && grep -E '^(# )?CT_' .config
grep (BSD grep) 2.5.1-FreeBSD
CT_CONFIGURE_has_xz=y

2864ae93af scripts: properly restore stdout/err/in at the end
Byt the end of the main script, the log file is being moved and
compressed, and the final destination might become read-only at any
time, so we consign stdout/err to oblivion.

This is incorrect, as some actions after may still fail (out of space,
for example).

So, properly restore stdout/err, but also stdin (useless, but harmless)
instead, so the user has a chance to see the error, especially since it
is not logged into the log file.

77705cdfe1 scripts: refine static linking check to better guide the user
The current mechanism to check if static linking is possible, and the mesage
displayed on failure, can be puzzling to the unsuspecting user.

Also, the current implementation is not using the existing infrastructure,
and is thus difficult to enhance with new tests.

So, switch to using the standard CT_DoExecLog infra, and use four tests to
check for the host compiler:
  - check we can run it
  - check it can build a trivial program
  - check it can statically link that program
  - check if it statically link with libstdc++

That should cover most of the problems. Hopefully.

(At the same time, fix a typo in a comment)

Currently, we rely on an existing external cross-compiler targetting

This can pause quite a few problems if that compiler is different from
the one we are building, because it could introduce some ABI issues.

This patch removes this dependency, by building the core compilers
as we do for standard cross, and also by building the binutils and

This means we no longer need to offer the cross-sompiler selection in

e2b9a81da3 scripts: check host features with host compiler
Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.

So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

892ef743c4 scripts: execute each steps in a subshell
To avoid variable leakage from one step to another, isolate the
steps from each others by running them in their own sub-shell.

This avoids variables leaking from one step to the others.

04da3418ca scripts: support extra host compiler flags
Allow the user to configure extra flags to pass to the host compiler
at build time.  Applies to both C and C++.

Useful on Ubuntu to turn off the stack protector and fortify defaults
so the program stands a better chance of running on other distros.

1c0488792d config: add a 'auto' value for the number of parallel jobs
When CT_PARALLEL_JOBS is -1, set the number of parallel jobs to the
number of online CPUs + 1.  Update documentation to match.

I find this useful when building in the cloud.  You can use the same
.config file and have the build adapt to the number of processors
available.  Limited testing shows that NCPUS+1 is faster than NCPUS+0
or NCPUS+2.

3e7036062c scripts: fix sysroot prefix dir
The sysroot prefix dir was broken in #4960f5d9f829 due to a mishap
when making the out-of-sysroot lib/ symlink: the './' was mistakenly
changed into a single '.' .

Although Jonathan suggested restoring the missing '/' to restore it to
normal operation, I prefered using an explicit pushd/popd to be extra
sure of the symlink location and target, along with a fix in the sysroot
relative directory calculation.
