cc1: error while loading shared libraries: libmpc.so.3:

問題是這樣的，通過buildroot做了一套工具鏈，將工具鏈打包出來放到其他機器上，大部分的編譯都可以

但編譯內核時報錯

  CHK     include/linux/version.h

  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CC      kernel/bounds.s
/opt/arm/usr/bin/../libexec/gcc/arm-broadcom-linux-gnueabi/4.7.3/cc1: error while loading shared libraries: libmpc.so.3: wrong ELF class: ELFCLASS64
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2
cp: cannot stat `./arch/arm/boot/Image': No such file or directory

cp ./arch/arm/boot/Image ../../mkubi/Image

通過ldd查看cc1的庫調用情況

zhangjiajie@hhpfmsvr8:/home/zhangjiajie/linux-3.6.5-arm/kernel/linux-3.6.5$ ldd /opt/arm/usr/bin/../libexec/gcc/arm-broadcom-linux-gnueabi/4.7.3/cc1
linux-gate.so.1 =>  (0xf7734000)
libmpc.so.3 => not found
libmpfr.so.4 => not found
libgmp.so.10 => not found
libdl.so.2 => /lib32/libdl.so.2 (0xf771d000)
libc.so.6 => /lib32/libc.so.6 (0xf75bb000)
/lib/ld-linux.so.2 (0xf7735000)

發現這幾個庫找不到，而在製作的機器上發現如下

基本確定與工具鏈的製作有關

嘗試將這幾個庫軟鏈接到/lib /usr/lib等目錄

export LD_LIBRARY_PATH="/usr/local/lib" ln -s /pathto/libmpc.so.2 /usr/local/lib sudo ldconfig
