Hi ALL I'm working on building arm-linux toolchain for GCC-3.4, xscale. I used CROSSTOOL-0.28-rc34/arm-iwmmxt, but the toolchain encountered problem when building a large c++ project. I had another arm-linux toolchain for GCC-3.3.2, which is OK to build that project. I checked the difference between this two toolchain, and thought it's probably that the gcc-core building process causes the problem. The old toolchain (GCC-3.3.2) used --with-inhibit-libc and --without-headers in GCC-CORE/configure. But the new toolchain built through CROSSTOOL is complex in building bootstrap compiler. I checked the explanation in CROSSTOOL and specified URL, but didn't catch the exact meaning. I'm continuing to check this process. But I want to know why CROSSTOOL uses the complex script since the simply configure option work fine? Is that mandotary for building GCC-3.4? Thanks! Following are the configure options of two toolchains: NEW toolchain: binutils-2.14.90.0.7/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/usr/local/arm-linux --disable-nls --with-sysroot=/usr/local/arm-linux/arm-linux glibc-2.3.2/configure --prefix=/usr --build=i686-pc-linux-gnu --host=arm-linux --without-cvs --disable-sanity-checks --with-headers=/usr/local/arm-linux/arm-linux/include --enable-hacker-mode gcc-3.4.0/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/usr/local/arm-linux --with-local-prefix=/usr/local/arm-linux/arm-linux --disable-multilib --with-newlib --with-cpu=iwmmxt --enable-cxx-flags=-mcpu=iwmmxt --without-headers --disable-nls --enable-threads=no --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c --disable-shared --without-fp glibc-2.3.2/configure --prefix=/usr --build=i686-pc-linux-gnu --host=arm-linux --without-fp --without-cvs --disable-profile --disable-debug --without-gd --without-tls --without-__thread --disable-sanity-checks --enable-shared --enable-add-ons=linuxthreads, --with-headers=/usr/local/arm-linux/arm-linux/include --enable-kernel=2.4.3 gcc-3.4.0/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/usr/local/arm-linux --with-cpu=iwmmxt --enable-cxx-flags=-mcpu=iwmmxt --with-headers=/usr/local/arm-linux/arm-linux/include --with-local-prefix=/usr/local/arm-linux/arm-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++ --enable-shared --enable-c99 --enable-long-long --without-fp OLD toolchain: ../binutils-2.14.90.0.7/configure --target=arm-linux --prefix=/root/oldtool/arm-linux --disable-nls ../gcc-3.3.2-core/configure --target=arm-linux --prefix=/root/oldtool/arm-linux --with-local-prefix=/root/oldtool/arm-linux/arm-linux --host=i686-host_pc-linux-gnu --disable-shared --disable-threads --with-cpu=xscale --with-inhibit-libc --enable-languages=c --without-headers --with-newlib --disable-nls --without-fp ../glibc-2.3.2/configure --prefix=/usr --host=arm-linux --build=i686-pc-linux-gnu --with-headers=/root/oldtool/arm-linux/arm-linux/include --without-__thread --enable-add-ons=linuxthreads --enable-shared --without-tls --without-fp --without-gd --disable-profile --disable-debug --disable-sanity-checks --with-cpu=xscale ../gcc-3.3.2/configure --target=arm-linux --host=i686-host_pc-linux-gnu --prefix=/root/oldtool/arm-linux --with-cpu=xscale --with-headers=/root/oldtool/arm-linux/arm-linux/include --with-local-prefix=/root/oldtool/arm-linux/arm-linux --disable-nls --enable-threads=posix --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c,c++ --enable-shared --enable-c99 --enable-long-long --without-fp -- best regards, -Bridge ------ Want more information?
