【问题】
折腾：
【记录】Ubuntu下用arm-xscale-linux-gnueabi交叉编译xmlrpc
期间，用gcc去编译，结果出错：
crifan@ubuntu:xmlrpc-c-1.06.31$ file lib/expat/gennmtab/gennmtab lib/expat/gennmtab/gennmtab: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.19, not stripped crifan@ubuntu:xmlrpc-c-1.06.31$ rm lib/expat/genmtab/genmtab rm: cannot remove ‘lib/expat/genmtab/genmtab’: No such file or directory crifan@ubuntu:xmlrpc-c-1.06.31$ rm lib/expat/gennmtab/gennmtab crifan@ubuntu:xmlrpc-c-1.06.31$ gcc -I. lib/expat/gennmtab/gennmtab.c -o lib/expat/gennmtab/gennmtab gcc: error trying to exec 'cc1': execvp: No such file or directory crifan@ubuntu:xmlrpc-c-1.06.31$
【解决过程】
1.参考：
Can not compile any C code under Xubuntu
去试试：

2.然后看看是否已解决问题，结果问题依旧。
3.参考：
gcc-4.6: error trying to exec ‘cc1’
去试试：
crifan@ubuntu:xmlrpc-c-1.06.31$ gcc -v Using built-in specs. COLLECT_GCC=gcc Target: arm-xscale-linux-gnueabi Configured with: /home/crifan/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/src/gcc-4.6.0/configure --build=i686-build_pc-linux-gnu --host=i686-build_pc-linux-gnu --target=arm-xscale-linux-gnueabi --prefix=/home/crifan/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi --with-sysroot=/home/crifan/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/arm-xscale-linux-gnueabi/sysroot --enable-languages=c,c++ --with-arch=armv5te --with-cpu=xscale --with-tune=xscale --with-float=softfp --with-pkgversion='crosstool-NG 1.18.0' --disable-__cxa_atexit --disable-libmudflap --disable-libgomp --disable-libssp --disable-libquadmath --disable-libquadmath-support --with-gmp=/home/crifan/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/arm-xscale-linux-gnueabi/buildtools --with-mpfr=/home/crifan/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/arm-xscale-linux-gnueabi/buildtools --with-mpc=/home/crifan/develop/crosstool-ng/crosstool-ng-1.18.0_build/.build/arm-xscale-linux-gnueabi/buildtools --with-ppl=no --with-cloog=no --with-libelf=no --with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm' --enable-threads=posix --enable-target-optspace --disable-nls --disable-multilib --with-local-prefix=/home/crifan/develop/crosstool-ng/x-tools/arm-xscale-linux-gnueabi/arm-xscale-linux-gnueabi/sysroot --enable-c99 --enable-long-long Thread model: posix gcc version 4.6.0 (crosstool-NG 1.18.0) crifan@ubuntu:xmlrpc-c-1.06.31$ ls /usr/lib/gcc/i686-linux-gnu/4.7 4.7/ 4.7.3/ crifan@ubuntu:xmlrpc-c-1.06.31$ ls /usr/lib/gcc/i686-linux-gnu/4.7^C crifan@ubuntu:xmlrpc-c-1.06.31$
很明显，此处，是不小心，把交叉工具链中的gcc的路径，加到环境变量中，导致x86的gcc，变成了xscale的gcc了。
4.所以，去看看自己的.bashrc中的PATH环境变量。
把PATH放到前面去：
#PATH=/opt/crosstool-ng/bin:/opt/crosscompile/xscale/gcc-4.6.0-glibc-2.9/bin:$PATH PATH=$PATH:/opt/crosstool-ng/bin:/opt/crosscompile/xscale/gcc-4.6.0-glibc-2.9/bin
这样，应该就可以先找到x86的gcc，而不是arm-xscale-linux-gnueabi的gcc了。
再source一下，结果竟然还是不行：
crifan@ubuntu:xmlrpc-c-1.06.31$ gedit ~/.bashrc crifan@ubuntu:xmlrpc-c-1.06.31$ source ~/.bashrc crifan@ubuntu:xmlrpc-c-1.06.31$ gcc -v Using built-in specs.

【总结】
去用gcc时，出现此处错误：
| gcc: error trying to exec ‘cc1’: execvp: No such file or directory |
我此处的问题的原因是：
之前在编译完毕xscale的交叉编译器后，将其路径加到PATH中时，不小心，加到$PATH之前了，导致系统去（通过PATH而）找到的（第一个）gcc，不是x86的gcc：
crifan@ubuntu:xmlrpc-c-1.06.31$ /usr/bin/gcc -v Using built-in specs.

所以解决办法是：
修改自己的.bashrc，确保其中交叉编译器的路径，是放在PATH之后的，比如：
#PATH=/opt/crosstool-ng/bin:/opt/crosscompile/xscale/gcc-4.6.0-glibc-2.9/bin:$PATH PATH=$PATH:/opt/crosstool-ng/bin:/opt/crosscompile/xscale/gcc-4.6.0-glibc-2.9/bin
这样，就确保了，系统寻找gcc等工具时，找到的是此处的x86的，而不是xscale的。
