CMake的（2.8.12.2）在Ubuntu 14.04编译器检查失败

Question

我试图运行这个简单的CMake命令：

$ cmake -D CMAKE_C_COMPILER=/usr/bin/gcc -D CMAKE_CXX_COMPILER=/usr/bin/g++ ./src/ 

我得到以下输出：

-- The C compiler identification is GNU 4.8.2

-- The CXX compiler identification is GNU 4.8.2

-- Check for working C compiler: /usr/bin/gcc

-- Check for working C compiler: /usr/bin/gcc -- broken

CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61 (message): The C compiler "/usr/bin/gcc" is not able to compile a simple test program.

的原因错误是：

gcc: error: unrecognized command line option ‘-rpath’

因为CMake的是试图用下面的命令链接：

/usr/bin/gcc -rpath /usr/local/openblas/lib CMakeFiles/cmTryCompileExec1190183239.dir/testCCompiler.c.o -o cmTryCompileExec1190183239 -rdynamic

据我所知，gcc没有单独的'-rpath'选项。我不确定为什么CMake正在尝试这样做。

还有其他人遇到过吗？解决方案？

谢谢！

PS：一些更多的信息，或许有用： 我想学习如何使用CMake的这样的目录结构非常简单：

-cmake_test/
    -bin/
    -src/
            -executable.cpp
            -CMakeLists.txt
    -CMakeLists.txt

Answer 1

我向大家道歉......从导致错误我前一阵子犯了一个错误。

总之答案是，我在我的.bashrc文件下列不正确的行：

export LDFLAGS="-rpath /usr/local/openblas/lib "$LDFLAGS

和CMake的有CMakeCommonLanguageInclude.cmake模块中的以下行：

set (CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS_INIT} $ENV{LDFLAGS}"

这显然导致CMAKE_EXE_LINKER_FLAGS设置为-rpath /usr/local/openblas/lib和 因此出现错误。改变.bashrc文件后：

export LDFLAGS="-Wl,-rpath=/usr/local/openblas/lib "$LDFLAGS

的问题就解决了。

我不知道为什么这并没有拿出GUI版本虽然:-)

我可能是通过读取OSX论坛或某事搞砸.bashrc文件。

无论如何感谢您的答案！
