cross-compiling with BeOS target works. - tweaked build-procedure to allow for proper generation of a i586-pc-beos cross-compiler on LINUX. - added documentation for creation of cross-compiler. git-svn-id: file:///srv/svn/repos/haiku/trunk/buildtools@11255 a95241bf-73f2-0310-859d-f6bbb57e9c96

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).
|
|
|
|
*** 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...
|
|
|
|
0 - Preparations
|
|
----------------
|
|
...and fetch the 'buildtools' module from the haiku CVS. You should then
|
|
have a 'buildtools' folder that contains folders named 'binutils' and
|
|
'gcc' (and this file, too!).
|
|
|
|
cd buildtools
|
|
|
|
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!
