[cfe-dev] Link external libraries to Clang lit tests

[Murali, Sriram]

Hello,
I need to link Clang, and a test case (added as the clang lit test) using an external library. I could do it by manually adding the options in the lit test.

For instance:

// RUN: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:<PATH_TO_LIB>
// RUN: %clang -o %t %s -L<PATH_TO_LIB> -l<libname> -lstdc++
// RUN: %t > %t.out

<<C++ Source>>

Is there a way to add the library path in the lit test configuration, and use it on my test case? I know that I cannot expect a similar test that links with external libraries in the clang test suite. But it would be helpful if someone can share their experience trying to accomplish something.

Thanks
Sriram
