Hi,

I have some library source code that builds for a Linux distro with glibc library. I want to build that code for alpine and musl libc and I'm finding some problems (I actually want to create an alpine linux package with the library). For example, I get this error when I try to build:

error: 'PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP' undeclared here (not in a function)
static pthread_mutex_t modGate  = PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP;
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Any help would be appreciated.

Regards,

Alex

I've also struggled with getting code to compile/run on Alpine. As an
interim fix, I ultimately decide to simply add glibc. You may find the
following repository helpful.

https://github.com/sgerrand/alpine-pkg-glibc/

I wrote a script to grab/install the glibc APK from the above repo. The
bottom half of the script includes the commented out commands from an
early attempt at building glibc directly (before I found the above
repo). You can find the aforementioned script at:
