Hi,

I do know that many people have ask this question many times.My problem is the same as theirs!

shm_process/main.c:19: undefined reference to `_shm_open'

Add the option : -pthread -lrt but it still does not work.

I want to know whether there exists some new approaches to solve this case.

Thanks !

shm_open() is not supported in the version of uClibc we ship currently
