我想使用新的编译器,因为它可以更好地处理C STL代码,并且因为GCC 4.8中的优化器使我的代码运行时间是Centos附带的GCC 4.4.7编译器的1/2.
有关如何做到这一点的任何建议？
摘自 documentation：
C standard library and headers
In order to build GCC,the C standard library and headers must be present for all target variants for which target libraries will be built (and not only the variant of the host C++ compiler).
This affects the popular ‘x86_64-unknown-linux-gnu’ platform (among other multilib targets),for which 64-bit (‘x86_64’) and 32-bit (‘i386’) libc headers are usually packaged separately. If you do a build of a native compiler on ‘x86_64-unknown-linux-gnu’,make sure you either have the 32-bit libc developer package properly installed (the exact name of the package depends on your distro) or you must build GCC as a 64-bit only compiler by configuring with the option –disable-multilib. Otherwise,you may encounter an error such as ‘fatal error: gnu/stubs-32.h: No such file’
