How to build gcc-2.95.3 for BeOS under Linux (a cross-compiler), which
will allow you to compile BeOS projects under Linux, i.e. the apps
that this compilers produces can only be executed on BeOS (not on Linux).
If all you are interested is compiling haiku on Linux, please refer to
the file 'INSTALL-as-haiku-cross-compiler' instead (that's easier).
These instructions are required only if you want to compile something
(applications, libraries) on LINUX which should be executed on BeOS R5,
BONE or ZETA.
*** the major work of creating the cross-compiler and describing the
*** process how to build it has been done by Eric Petit <titer@m0k.org>,
*** so if you think this cross-compiler is great, please tell him.
-----------------------------------------------------------------------
On your Linux-box, open a shell...

...and fetch the 'buildtools' module from the haiku SVN. You should then
have a 'buildtools' folder that contains folders named 'binutils' and
'gcc' (and this file, too!).
cd buildtools/legacy
Now decide where you want to install the cross-compiler. The install
folder will be referred to as $PREFIX. I suggest to install to
/opt/cross-tools, but you can basically put it anywhere you like.
export PREFIX=/opt/cross-tools
and add it the path:
export PATH=$PATH:$PREFIX/bin
Create two folders for the headers and libraries, say $BEINC and
$BELIB:
mkdir beinc
export BEINC=$(pwd)/beinc
mkdir belib
export BELIB=$(pwd)/belib
Copy all contents from /boot/develop/lib/x86/ on your BeOS install to
$BELIBS on your Linux box (make sure symbolic links are followed). You
should have $BELIBS/libbe.so, etc.
Copy all contents from /boot/develop/headers/ on your BeOS install to
$BEINCS on your Linux box. You should have $BEINCS/be/AppKit.h, etc.
1 - Building binutils
---------------------
mkdir binutils-obj
cd binutils-obj
CFLAGS="-O2" CXXFLAGS="-O2" ../binutils/configure --prefix=$PREFIX \
--target=i586-pc-beos --disable-nls --enable-shared=yes
make && make install
cd ..
2 - Building gcc/g++
--------------------
mkdir -p $PREFIX/lib/gcc-lib/i586-pc-beos/2.95.3-beos-041202
mkdir gcc-obj
cd gcc-obj
CFLAGS="-O2" CXXFLAGS="-O2" ../gcc/configure --prefix=$PREFIX \
--target=i586-pc-beos --disable-nls --enable-shared=yes \
--enable-languages=c,c++ --with-headers=$BEINC --with-libs=$BELIB
make cross && make install
cd ..
Ok, now everything is compiled and installed, waiting to be used:
i586-pc-beos-gcc test.c
would compile the file test.c with the fresh cross-compiler.
So have fun!
