configure:error:C预处理器无法进行健全性检查

Question

我正在Ubuntu 12.04 x86_64上编译几个库.首先,我使用GCC 4.7.2编译了这些库并且一切顺利.然后我尝试使用Inte Composer 2013 u2重新编译它们.我做的目的是:

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并得到以下错误:

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:

这可能有什么不对？

Answer 1

这个问题可能是,在GNU做出表示隐变量"C++编译器"不是CPP但是CXX,而CPP是表示"你的C预处理器"的隐含变量; 所以你的

export CPP=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc

告诉configure我icpc是预处理器,并且CXX假定默认为g ++.

./configure错误支持此功能:

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

要不就:

./configure CXX=/opt/intel/composer_xe_2013.2.146/bin/intel64/icpc

Answer 2

FWIW，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应该使用该-E标志运行预处理器。
