クロスコンパイル環境作り方 †

もっとスマートな方法がありました。ということでボツネタです。
Debian on coLinux上にsh4のクロスビルド環境を構築する。

dpkg-cross †

apt-get install dpkg-cross

• /etc/dpkg/cross-compile

  #default_arch = m68k
  default_arch = sh4
  

toolchain-source †

apt-get install toolchain-source

mkidr /home/build
cd /home/build
tpkg-make sh4-linux

binutiles †

colinux:/home/build# cd binutils-sh4-linux-2.14.90.0.7
colinux:/home/build/binutils-sh4-linux-2.14.90.0.7# debuild -uc -us
colinux:/home/build/binutils-sh4-linux-2.14.90.0.7# debi

libc †

• tpkg-install-libc.dodes.sh4

gcc-3.3.4 †

toolchain-sourceのgccは3.3.3なので3.3.4に置き換える。
gcc-3.3.4のソースを取ってきて

apt-get source gcc-3.3
cd gcc-3.3-3.3.4
cp gcc-3.3.4.tar.bz2 /usr/src/toolchain
cp debian
cp rules.patch patches
cp -a patches /usr/src/toolchain/patches/gcc-3.3.4
cd /usr/src/toolchain/patches
mv gcc gcc-3.3.3
ln -s gcc-3.3.4 gcc

colinux:/home/build# cd gcc-sh4-linux-3.3.3
colinux:/home/build# perl -pi -e s'/__thread/__thread_param/'  \
/usr/sh4-linux/include/bits/sigthread.h

colinux:/home/build# perl -pi -e s'/__thread/__thread_param/'  \
/usr/sh4-linux/include/pthread.h

/home/build/gcc-sh4-linux-3.3.3# debuild -uc -us
/home/build/gcc-sh4-linux-3.3.3# debi
