Can't compile the Python package because of an undeclared value

Hello!

I try to build a small docker container with a python script that uses the Ice package and I can't build it via pip.

There are several official images with python and tried several of them in different combinations:
3.6.3-jessie — this is the image with python 3.6.3 based on Debian Jessie with a lot of packages and gcc version 4.9.2. It works well and everything is compiled smoothly I suppose because of gcc version. I'm not just satisfied with the container size in the result.

I also tried two images based on alpine linux version 3.4 and 3.6 with gcc version 5.3.0 and 6.3.0 respectively and in both cases I get the same exception:

src/ice/cpp/src/IceUtil/RecMutex.cpp: In member function 'void IceUtil::RecMutex::init(IceUtil::MutexProtocol)':
src/ice/cpp/src/IceUtil/RecMutex.cpp:129:43: error: 'PTHREAD_MUTEX_RECURSIVE_NP' was not declared in this scope
     rc = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE_NP);
                                           ^
error: command 'gcc' failed with exit status 1

I tried to build zeroc-ice python packages version 3.6.4 and 3.7.0.1 and in all possible variants I got that error. It doesn't look like a missing dependency error for me and I don't know what I can I do here.

Do you have any thoughts about it? Is this because of the compiler version or I can just configure it somehow or add a dependency?

g++(tried clang too, the same result) bzip2-dev openssl-dev — this is a minimal dependencies to get that error that I found out

    Hi,

    I believe this is caused by the musl C library from Alpine Linux which doesn't support PTHREAD_MUTEX_RECURSIVE_NP but instead supports PTHREAD_MUTEX_RECURSIVE.

    You could try installing the PyPI package with the following to see if it works around the issue:

    pip install --global-option=build_ext --global-option="-DPTHREAD_MUTEX_RECURSIVE_NP=1" zeroc-ice

    Can you let us know now if that solves your issue? We'll look into fixing our code to check for this macro.

    Cheers,
    Benoit.

    Hi,

    Thank you for the explanation! Unfortunately, your suggestion doesn't resolve the issue but I have another error message now:

    src/ice/cpp/src/IceUtil/RecMutex.cpp: In member function 'void IceUtil::RecMutex::init(IceUtil::MutexProtocol)':
    <command-line>:0:30: error: lvalue required as left operand of assignment
    src/ice/cpp/src/IceUtil/RecMutex.cpp:129:43: note: in expansion of macro 'PTHREAD_MUTEX_RECURSIVE_NP'
         rc = pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE_NP);
                                               ^~~~~~~~~~~~~~~~~~~~~~~~~~
    error: command 'gcc' failed with exit status 1

    Hi,

    Can you try another workaround? Try using the following instead:

    pip install --global-option=build_ext --global-option="-D__USE_UNIX98" zeroc-ice
    

    Our code checks for this macro (defined with Glibc) and use PTHREAD_MUTEX_RECURSIVE and PTHREAD_MUTEX_ERROR_CHECK when it's defined. We'll fix this check in an upcoming released in order to be compatible with the musl C library.

    Cheers,
    Benoit

    Yep! This one works! Thank a lot, I will use this workaround until new release with the fix.
