为什么额外的-I标志（包含目录）会破坏编译？ （使用英特尔编译器）

Question

我安装了英特尔ComposerXE 2013的试用版（包含ICC 14.0.1编译器）。我的测试程序如下：

#include <boost/graph/adjacency_list.hpp>
#include <iostream>

typedef boost::adjacency_list<boost::vecS, boost::vecS, boost::undirectedS> UndirectedGraph;

int main() {

  UndirectedGraph G(10);

return 0;  
}

我使用intel编译器标志编译代码如下

/home/intel/bin/icpc                                 //binary
   -L/home/intel/composerxe/lib/intel64              //lib path
   -I/home/intel/composerxe/include                  //include path for ICPC
   -I/home/boost_1_55_0                              //boost path
   -std=c++11 test.cpp                              //  c++11 flags 

我为BOOST HASH.hpp和type_traits.hpp文件

收到以下错误

现在我使用此编译而没有ICPC INCLUDE PATH

/home/intel/bin/icpc                                 //binary
   -L/home/intel/composerxe/lib/intel64              //lib path
                  //removed the ICPC INCLUDE PATH HERE 
   -I/home/boost_1_55_0                              //boost path
   -std=c++11 test.cpp                               // c++11 flags 

这可以很好地编译ZERO错误

为什么会这样？

我的LD_LIBRARY_PATH和PATH变量为空。没有GCC或其路径设置的任何其他编译器。我在编译期间给出了所有路径。

Answer 1

可能在给定目录中有一些文件与其他文件具有相同的名称，当它为#included时，编译将失败或成功，具体取决于选择这两个相同名称的文件。< / p>

要验证是否是这种情况，请使用选项-H编译这两种情况，它将列出所有包含的文件，并比较输出。

要在不删除目录的情况下解决问题，请将其移至命令行的末尾：

/home/intel/bin/icpc                                 //binary
   -L/home/intel/composerxe/lib/intel64              //lib path
   -I/home/boost_1_55_0                              //boost path
   -I/home/intel/composerxe/include                  //include path for ICPC
   -std=c++11 test.cpp                              //  c++11 flags
