npth-1.6: error: unknown type name ‘pthread_rwlock_t’

Description

Hello,

I'm trying to compile npth on a sparc machine which fails with:

I checked my pthread.h in usr/include/pthread.h and for me it looks like pthread_rwlock_t is defined somewhere else. Can someone give me a hint how to fix this?

I uploaded the complete build directory to github - see external link.

Any help appreciated. Thanks

Hello @gniibe, you did the last work on nPTh. Would you be so kind and look into this?

It was fixed in: rPTH223e59f992f9: build: Define _NPTH_NO_RWLOCK when we can't find pthread_rwlock_t. and rPTH09a12a679ec0: Fix how we expose rwlock API.

Perhaps, it's better to have new release (last release was three years ago).

Okay, any thing else missing in nPth?

I have a little concern for glibc 2.34 (which has dummy libpthread and all is actually in libc).

Debian, Gentoo, Archlinux are still using glibc 2.33 or older.

Looking Fedora which uses glibc 2.34, it looks OK.

Thanks! I was able to compile the current source code of npth (1.7) (with gcc 7.1. and ldd (GNU libc) 2.3.2 ). The error error: unknown type name ‘pthread_rwlock_t’ didn't occour.
