在Ubuntu 12.04.1下構建cross-gcc 4.7.2

Question

我試圖構建gcc。有了這個參數：

AR=ar LDFLAGS="-Wl,-rpath,${CLFS}/cross-tools/lib" \ 
    ../gcc-4.7.2/configure --prefix=${CLFS}/cross-tools \ 
    --build=${CLFS_HOST} --host=${CLFS_HOST} --target=${CLFS_TARGET} \ 
    --with-sysroot=${CLFS} --disable-nls --disable-shared \ 
    --with-mpfr=${CLFS}/cross-tools --with-gmp=${CLFS}/cross-tools \ 
    --with-mpc=${CLFS}/cross-tools --without-headers --with-newlib \ 
    --disable-decimal-float --disable-libgomp --disable-libmudflap \ 
    --disable-libssp --disable-threads --enable-languages=c \ 
    --disable-multilib --with-abi=${CLFS_ABI} --with-arch=${CLFS_ARM_ARCH} \ 
    --with-mode=${CLFS_ARM_MODE} --with-float=${CLFS_FLOAT} \ 
    --with-fpu=${CLFS_FPU} 

這是我的.bashrc：

的/mnt/clfs/sources/gcc-build/arm-unknown-linux-uclibceabi/libgcc內容是：

This file contains any messages produced by compilers while 
running configure, to aid debugging if configure makes a mistake. 

It was created by GNU C Runtime Library configure 1.0, which was 
generated by GNU Autoconf 2.64. Invocation command line was

你有什麼想法？

Answer 1

在this website他們說我需要這樣的配置：ARMv7-A Thumb-2 - Little-Endian, Soft-Float, GLIBC我的BeagleBoard-XM ..因爲它擁有的ARM Cortex-A8

Answer 2

這在FAQ中回答，請參閱http://gcc.gnu.org/wiki/FAQ#configure_suffix - 答案是幾乎可以肯定的是，你沒有設置LD_LIBRARY_PATH=${CLFS}/cross-tools

解決方法是不設置它，而是跟隨在http://gcc.gnu.org/wiki/InstallingGCC關於安裝GMP的說明，MPFR和MPC：可以從Ubuntu軟件包管理器（例如Synaptic或其它軟件）安裝它們，或者使用download_prerequisites腳本。 請勿將安裝在${CLFS}/cross-tools中，否則您只會遇到困難。
