The VLC port of GCC requires some prep work before it's ready for action. | |||
There are two major problems with it: | |||
It does not honor the <tt>#pragma pack()</tt> directive and there is a store layout bug for packed structs. | |||
Hence, it needs to be rebuilt. | |||
As a welcome aside though, the procedure described in the following subsections can be applied to linux | |||
or cygwin based environment. | |||
This means that the cross compiler can be installed onto a Windows ([http://www.cygwin.org Cygwin]) | |||
machine as well. | |||
=== Cross compiler === | |||
The build process is carried out in two steps, first the binutils and then the gcc cross compiler. | |||
Begin by designating a directory where all source downloads and build will take place. | |||
(''Note:'' the patches by the VLC guys target specific GCC/binutils versions. | |||
We'll rebuild those exact versions as they are good enough for the time being.) | |||
==== Binutils ==== | |||
Checkout the binutils source, as described in the [http://www.gnu.org/software/binutils/ GNU Binutils] | |||
page but designating a revision date as well: | |||
cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src login | |||
{enter "anoncvs" as the password} | |||
cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src co -D 20050514 binutils | |||
CD into the root of the source tree and patch with the three | |||
[http://download.videolan.org/pub/testing/wince/patches/ VLC binutils patches] (may patch with a little fuzz). | |||
Configure the build: | |||
./configure --target=arm-wince-pe --prefix=PREFIX_TO_CROSS_COMPILER | |||
(PREFIX_TO_CROSS_COMPILER is the path where the cross compiler will be installed. | |||
In linux it is: <tt>/usr/local/wince/cross-tools</tt>) | |||
Make and make install. You may need to manually run ranlib on some generated libs | |||
during making. | |||
==== GCC ==== | |||
Checkout the GCC source: | |||
svn -q checkout -r {20050511} svn://gcc.gnu.org/svn/gcc/trunk gcc | |||
(Note the date. It does not match the date in the VLC patches. Also, later revisions | |||
contain severe bugs) | |||
Now come the patches. | |||
:* First aaply the VLC [http://download.videolan.org/pub/testing/wince/patches/ VLC patch] (maybe a little fuzz here as well). | |||
:* Then, patch <tt>gcc/stor-layout.c</tt> with the patch described [http://gcc.gnu.org/ml/gcc-patches/2006-10/msg01115.html here]. | |||
:* Finally, in <tt>gcc/config/arm/arm.h</tt>, stick the following define somewhere (before the architecture define is OK): | |||
#define HANDLE_PRAGMA_PACK_PUSH_POP | |||
In the root of the GCC source tree, make a directory called <tt>wince</tt>. | |||
CD into it and create a file called <tt>build.sh</tt> with the following stuff (substitute PREFIX_TO_CROSS_COMPILER), and run it:<br> | |||
<tt> export PATH=PREFIX_TO_CROSS_COMPILER/bin:$PATH</tt><br> | |||
<tt> ../configure --with-gcc --with-gnu-ld --with-gnu-as --target=arm-wince-pe --prefix=PREFIX_TO_CROSS_COMPILER --disable-threads --disable-nls --enable-languages=c++ --disable-win32-registry --disable-interwork --disable-multilib</tt><br> | |||
<tt> make install</tt> | |||
==== Finish up ==== | |||
We need to copy over some stuff from the full GCC tarball. | |||
Get [http://download.videolan.org/pub/testing/wince/wince-arm-gcc4.0.0-cvs-linux-crosscompiler-20050517.tar.bz2 the binary tarball] and unpack it somewhere. | |||
:* Copy recursively all of <tt>usr/local/wince/cross-tools/include/</tt> into your <tt>PREFIX_TO_CROSS_COMPILER/include</tt>. | |||
:* Copy all of the libs in <tt>usr/local/wince/cross-tools/lib</tt> into your <tt>PREFIX_TO_CROSS_COMPILER/lib</tt> (except libiberty.a). | |||
:* CD into your <tt>PREFIX_TO_CROSS_COMPILER/arm-wince-pe/lib</tt> and make the following two symbolic links: | |||
ln -s ../../lib/corelibc.lib crt0.o | |||
ln -s ../../lib/coredll.lib c.lib | |||
Done :-) | |||
(''Note:'' In linux, it is much easier to get the binary tarball, extract it into the root of the filesystem, and then build | |||
the binutils and GCC replacing essentially the offending files (C++ compiler etc). This final step in this case is not be required) | |||
=== ScummVM === | |||
''Assuming you have installed the toolchain in its default place'' | ''Assuming you have installed the toolchain in its default place'' | ||
This is the procedure for building ScummVM, provided the compiler is patched as described above: | |||
