Hi GCC maintainers I've spent few days trying to figure out how to build a cross compiler for my linux distribution. I've found plenty of instructions but only the unsatisfying instructions have been worked. The particular instructions that work are located at the "cross linux from scratch" -tutorial: http://www.clfs.org/view/CLFS-3.0.0-SYSTEMD/x86_64-64/cross-tools/chapter.html The problem with these tutorials are that they propose to patch the gcc/config -directory and build files to get the library compile correct. I wrote my current build scripts based on them and got it to work. The problem is that I cannot trust that they keep working on. I thought for a moment that I had found good instructions at http://preshing.com/20141119/how-to-build-a-gcc-cross-compiler/ but neither these worked out. So consider that you're starting out a distribution. What is the preferred way of compiling a cross-compiler and then the compiler for your platform? The biggest concern seems to be that the paths Here's a sample of what kind of crazy the clfs scripts consist of, after they've patched the gcc/config and replaced every /lib(64)? -pattern with /tools/lib AR=ar LDFLAGS="-Wl,-rpath,/cross-tools/lib" \ $GCC_SOURCES/configure --prefix=/cross-tools \ --build=${LELUX_HOST} --host=${LELUX_HOST} --target=${LELUX_TARGET} \ --with-sysroot=${LELUX} --with-local-prefix=/tools \ --with-native-system-header-dir=/tools/include \ --disable-nls --disable-shared \ --with-mpfr=/cross-tools \ --with-gmp=/cross-tools \ --with-mpc=/cross-tools \ --without-headers --with-newlib --disable-decimal-float --disable-libgomp \ --disable-libmudflap --disable-libssp --disable-libatomic --disable-libitm \ --disable-libsanitizer --disable-libquadmath --disable-threads \ --disable-multilib --disable-target-zlib --with-system-zlib \ --enable-languages=c --enable-checking=release make -j4 all-gcc all-target-libgcc make install-gcc install-target-libgcc I feel this is important, as there's many other people constructing cross compiler tools. Actually I just looked in how gcw0 toolchain has been configured: Configured with: ./configure --prefix=/opt/gcw0-toolchain/usr --sysconfdir=/opt/gcw0-toolchain/etc --enable-shared --enable-static --target=mipsel-gcw0-linux-uclibc --with-sysroot=/opt/gcw0-toolchain/usr/mipsel-gcw0-linux-uclibc/sysroot --disable-__cxa_atexit --with-gnu-ld --disable-libssp --disable-multilib --with-gmp=/opt/gcw0-toolchain/usr --with-mpfr=/opt/gcw0-toolchain/usr --enable-target-optspace --disable-libsanitizer --enable-tls --disable-libmudflap --enable-threads --with-mpc=/opt/gcw0-toolchain/usr --disable-decimal-float --with-arch=mips32r2 --with-tune=mips32r2 --with-abi=32 --with-pkgversion='Buildroot 2014.05-gbb847d4' --with-bugurl=http://bugs.buildroot.net/ --enable-languages=c,c++ --with-build-time-tools=/opt/gcw0-toolchain/usr/mipsel-gcw0-linux-uclibc/bin --disable-libgomp --enable-lto Doesn't seem that different.
