We had to build gcc 3.02 with Hard Hat Linux's gcc2.9x for sh4. Here's how we did it, just in case anyone else needs to do that. - Dan #!/bin/sh set -x -e WORKDIR=`pwd` #wget ftp://ftp.gnu.org/pub/gnu/gcc/gcc-3.0.2/gcc-3.0.2.tar.gz #wget ftp://ftp.m17n.org/pub/linux-sh/testing/gcc-sh-linux_3.0.2-3.diff.gz # Muck around in the hardhat tree to let the gcc build process find what it # needs. FIXME These steps must all be run as root. cd /opt/hardhat/devkit/sh/sh4_le # Avoid exit if links exist by using a subshell ( ln -s sh4el-hardhat-linux sh4-linux cd bin ln -s sh_sh4_le-ar sh4-linux-ar ln -s sh_sh4_le-ld sh4-linux-ld ln -s sh_sh4_le-nm sh4-linux-nm ln -s sh_sh4_le-ranlib sh4-linux-ranlib ln -s sh_sh4_le-strip sh4-linux-strip ) find . -name crt?.o -exec cp {} sh4-linux/lib \; # Extract the source into the same directory as the tarballs cd $WORKDIR tar zxvf gcc-3.0.2.tar.gz rm -rf gcc-sh-linux-3.0.2 mv gcc-3.0.2 gcc-sh-linux-3.0.2 zcat gcc-sh-linux_3.0.2-3.diff.gz | patch -p0 PATH=/opt/hardhat/devkit/sh/sh4_le/bin:$PATH export PATH rm -rf gcc-build mkdir gcc-build cd gcc-build ../gcc-sh-linux-3.0.2/configure \ --target=sh4-linux \ --prefix=/opt/hardhat/devkit/sh/sh4_le \ --with-headers=/opt/hardhat/devkit/sh/sh4_le/target/usr/include \ --enable-shared \ --enable-long-long \ --enable-threads=posix \ --enable-langugages=c,c++ \ --disable-c99 \ --disable-nls sed -e 's/^TARGET_CONFIGDIRS.*$/TARGET_CONFIGDIRS = libiberty libstdc++-v3/' Makefile > Makefile.new mv -f Makefile.new Makefile make make install # remove gcc3.0.0 stuff rm /opt/hardhat/devkit/sh/sh4_le/target/usr/lib/libstdc++.* # cp -d is not portable; could do same thing with cpio... cp -d /opt/hardhat/devkit/sh/sh4_le/sh4-linux/lib/libs* /opt/hardhat/devkit/sh/sh4_le/target/usr/lib cp -d /opt/hardhat/devkit/sh/sh4_le/sh4-linux/lib/libgcc_s* /opt/hardhat/devkit/sh/sh4_le/target/lib cp -R -d /opt/hardhat/devkit/sh/sh4_le/include/g++-v3 /opt/hardhat/devkit/sh/sh4_le/target/usr/include (cd /opt/hardhat/devkit/sh/sh4_le/sh4-linux ; cp -R -d ../target/usr/include .) ------ Want more information?
