Building GCC4
From wiki.gp2x.org
Just notes for now
Download these to your downloads directory
- binutils-2.16.1.tar.bz2
- gcc-4.0.2.tar.bz2
- glibc-2.3.5.tar.bz2
- glibc-linuxthreads-2.3.5.tar.bz2
use the ME kernel source, you must make menuconfig and make dep using the ME gcc-2.95.3 to get usable headers
if you don't have the ME kernel, try Kernel Headers, don't forget to change the KERNEL_DIR in the script.
Minimal patch for glibc: glibc-2.3.5-arm.patch. Note this is downloaded and applied automatically.
where i cribbed most of the patches: 0218363205270.patch.
Here's a first attempt at a script (it works for me):
# Your target binary prefix
TARGET=arm-linux-gnu
# Your installation prefix
PREFIX=/usr/local/open2x
# Directory where you keep your tarballs
DOWNLOADS=/usr/portage/distfiles
KERNEL_DIR=./linux-mmsp2
# check md5s ??
# install binutils
tar xjf ${DOWNLOADS}/binutils-2.16.1.tar.bz2
cd binutils-2.16.1/
./configure --prefix=${PREFIX} --target=${TARGET} --with-sysroot=${PREFIX} || exit
make || exit
make install
cd ..
echo --- binutils all done ---
# update our path for the new programs we just installed
export PATH=${PREFIX}/bin:$PATH
# you should have already make dep in the kernel using the gcc 2.9.5 tools
# do this manually for now
#cd ${KERNEL_DIR}
#make menuconfig
#make dep
#cd ..
mkdir -p ${PREFIX}/include
mkdir -p ${PREFIX}/${TARGET}/include
