[cfe-dev] Linking a plugin against clang/LLVM libraries

[Laszlo Nagy]

hi Ehsan,

it's good that you don't have linking problem now. to fix the next problem:
can you show us, how do you call the compiler with your plugin? and also
try to put printouts into the code, to see where it is. or could you share
the plugin source somehow?

regards,
Laszlo
