Re: [DynInst_API:] Status of Dyninst 10

Hi Stan,

The CMakeError.log is misleading. The real error should be output to the terminal.Â

CMake will always test different flags for pthread, such as -lpthreads, -pthreads, and so on. Some of them will fail and CMake will write them to CMakeError.log. Somehow CMake does not write the real error to CMakeError.log.

Let us know the real error.

Thanks,
