I was trying an openmp code with clang compiler as specified in 我正在尝试使用clang编译器的openmp代码

http://clang-omp.github.io/ http://clang-omp.github.io/

I downloaded the code via git and did make and make install . 我通过git下载了代码并做了make和make install 。 It successfully installed the clang compiler with openmp support. 它成功安装了具有openmp支持的clang编译器。 But when I try to compile a sample code (specified in the above link), I get the following error : 但是当我尝试编译示例代码（在上面的链接中指定）时，我收到以下错误：

/usr/bin/ld: cannot find -liomp5 / usr / bin / ld：找不到-liomp5

I did not specify path to include and lib as mentioned in the site, but I intend to specify them while compiling on command line with -L and -I options. 我没有指定网站中提到的包含和lib的路径，但我打算在使用-L和-I选项在命令行上编译时指定它们。

$ clang -I/usr/lib/gcc/i686-linux-gnu/4.6/include -fopenmp test.c -o test $ clang -I/usr/lib/gcc/i686-linux-gnu/4.6/include -fopenmp test.c -o test

However, I could not find path for iomp5 lib and hence I got the above error. 但是，我找不到iomp5 lib的路径，因此我得到了上述错误。 Can someone please tell me how to resolve this? 有人可以告诉我如何解决这个问题？
