我正在Ubuntu12.04 x86_64上编译几个库。首先,我用GCC 4.7.2编译了这些库,一切都很顺利。然后我尝试用Inte Composer 2013 u2重新编译它们。为此,我这样做了:
export CC=/opt/intel/composer_xe_2013.2.146/bin/intel64/icc
export CPP=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc
然后我运行./configure
,得到以下错误:
checking how to run the C preprocessor... /opt/intel/composer_xe_2013.2.146/bin/intel64/icpc
configure: error: in `/var/www/workspace/freetype/freetype-2.4.11/builds/unix':
configure: error: C preprocessor "/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc" fails sanity check
See `config.log' for more details
make: *** [setup] Error 1
配置日志文件包含此错误:

这里会有什么问题呢?

问题很可能是,表示“您的C++编译器”的GNU make隐式变量不是CPP
,而是CXX
,而CPP
是表示“您的C预处理器”的隐式变量;因此,您的
export CPP=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc
告诉configure
icpc是预处理器,而CXX
可能默认为g++。
./configure
错误支持这一点:
正在检查如何运行C预处理器.../opt/intel/composer_xe_2013.2.146/bin/intel64/icpc
尝试:
export CXX=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc
或者只是:
./configure CXX=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc

顺便说一句,我今天遇到了这个问题,我的解决方案是
export CPP='<path to icpc> -E'
也就是说,告诉configure预处理器应该使用-E
标志运行。

谢谢Menno,在我的例子中,导出没有做到这一点,但已经很接近了。正在通过CPP=...要进行配置,请执行以下操作:
mkdir build
cd build
../configure --prefix=/usr/local/gcc/ CC=/usr/local/gcc/bin/gcc \
CXX=/usr/local/gcc/bin/g++ CPP='/usr/local/gcc/bin/g++ -E'
