c++/9/thread:126: undefined reference to `pthread_create'

[chriszhao13]

Hello! Adam. Thanks so much for the _[fast_matrixmarket] project you created. I try to cmake the example. However, there is an issue showing _/9/thread:126: undefined reference to `pthreadcreate'. I fix it by _target_link_libraries(simple1 fast_matrix_market::fast_matrixmarket pthread). Though, I think, the pthread libraries should be linked by the [fast_matrix_market] market itself. I want to verify it.

wishes!

Interesting.

What version of compiler and OS are you running? What command printed that error?

FMM does not use pthreads, only native C++11 threads. These may be internally implemented using pthreads by some compilers, but do not require additional link arguments.

@chriszhao13 I tried some additional platforms and compiler versions and was able to reproduce your issue. I believe your issue is fixed, would you mind retesting the latest main on your platform?
