This patch adds libstdc++ to libports. With the previous version of the
stdcxx library, the build system used the C++ standard library that
comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.
Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.
Apparently, GNU make 3.81 picks the generic '%.h' rule instead of the
more specific 'rpc/%.h' rule during the preparation of the libc.
Changing the order of the rules solves the problem.
The new version works fine but there is an issue with connect()
that needs the included patch:
There is no actual handling of EALREADY in lwip. It sets errno
to EALREADY when the connection was established. Unfortunatly this
is really bad because most programs expect to receive errno EISCONN
if the connection was successfully established. So this behaviour
breaks Qt4 and several noux/net packages (like lynx) because those
programs end up in an endless loop trying to connect via an already
connected socket. The longterm solution would be fixing the wrong
behaviour in lwip (there are already bug-reports on lwip's mailinglist)
but for now, it works well enough to simple change lwip's err_to_errno
table to set errno to EISCONN when the connection was established.
Certain rpc headers are needed for compiling getaddrinfo.c. Unfortunatly
that means we have to generate _a few_ header files which we do when we
prepare the libc.
These header files need to be created before the symlinks. Also, some of
these header files depend on a patch. Therefore we apply the patches
first, generate the header files and in the end we create the symlinks.
Fixes#296.
Our FreeBSD libc based libc defines SOL_SOCKET as 0xffff. We change
lwip's definition from 0xfff to match ours. This prevents us from
converting the level when we call {g,s}etsockopt.
Fixes#292.
libcrypto provides certain optimized assembler functions which
unfortunatly are non-pic. Therefore this asm code is removed
and libcrypto is build with -DOPENSSL_NO_ASM.
Because the asm code is not needed anymore, its generation is
also removed from openssl.mk.
import-libssl.mk was also added because it is essential for building
programs which depend on libssl.
Fixes#291.
Fixes#294.
We are using bison to generate certain files when preparing the libc.
However the yacc(1) wrapper script is used instead of calling bison
directly which does not work if bison is not installed but the original
yacc(1).
Fixes#225. Fixes#227.
modexp512 and rc4-md5 code were missing for x86_64. The files are now
generated on openssl-prepare and will be used when building for x86_64.
Fixes#224.
This commit contains the initial port of OpenSSL to Genode. It certainly
needs some more work to get things straight - it compiles fine but does
not work because of a NULL pointer exception.
With this patch the SDL-based 'avplay' media player, which is part of
'libav', can be built. The run script expects a media file named
'mediafile' in the 'bin' directory.
Fixes#216.
The Lua runtime library is built in two variants: ANSI C and C++. The
C++ provides all Lua API function with C++ linkage and uses C++
exceptions instead of setjmp/longjmp for protected execution of Lua
chunks.
The ported version of Lua is 5.1.5.
This patch implements a Genode-specific audio backend for SDL.
The audio volume (in percent) can be configured in the config file of the
SDL application:
<config>
<sdl_audio_volume value="100"/>
</config>
Fixes#204.
MuPDF is a fast and versatile PDF rendering library with only a few
dependencies. It depends on openjpeg (JPEG2000 codec) and jbig2dec (b/w
image compression library). Therefore, this patch comprises the ports of
these libraries as well. All libraries compile well in the Genode build
system but are not tested yet.
