Using this version on a somewhat older windows pc using commandline,
flac -8e --no-padding

WARNING, cannot set number of threads: multithreading was not enabled during compilation of this binary

Current git brakes multithreading here completely also.

That is strange, I have no such problems. Not on Windows (MinGW64) nor on Linux.

It is the m-ab_s build that compiles without threads. I've tested that, but not an independent build. I'll do that shortly.

This separate build (64 bit, AVX2 optimised) was built with threads enabled:

the m-ab_s build
What is that?
Media-AutoBuild_Suite - for building audio and video encoders/decoders and, ultimately, ffmpeg and mpv. It uses configure for the flac build.

I just built the current git version.  Multi-threading works for me.

Not here.
Ops, sorry. No idea what exe files i copied from where for the former test. Recent git indeed still brakes multithreading here.

Maybe this is related: https://github.com/xiph/flac/commit/0c8afdf35aef9004d013c440bc75b8b77f8f4c26

Well, the build I made at "Reply #107" was from the git of March 7 cloned a few minutes before the time of the post, and threading worked at that point. The m-ab_s build doesn't use cmake and I have no idea whether other build systems default to multithreading, I'm guessing not.

I encountered this problem as well.  The pthread libraries had recently been updated in MSYS2 so I downgraded to the prior version and configure enabled multithreading as expected.  Cmake had no such problem with the latest pthread.

Ah, OK, I guess that explains it. I make use of the MSYS64 install that m-ab_s uses for general GCC compiles but use the cmake build for FLAC.

There seems to be a problem with the latest winpthread in msys2 indeed. One function used by the autotools pthread macro results in an error, making configure think pthread is not available.

Here is the macro documentation that FLAC uses: https://www.gnu.org/software/autoconf-archive/ax_pthread.html

And here is the error that is in config.log

I'm not sure what to do at this point. Perhaps it is best to leave it for now, as it seems that this is a bug in msys2 that will probably be fixed.

For anyone wanting a quick fix, go to m4/ax_pthread.m4 in the FLAC source directory, and replace lins 331-333
Code: [Select]
                        pthread_attr_init(&attr);
                        pthread_cleanup_push(routine, 0);
                        pthread_cleanup_pop(0) /* ; */])],

With the following
Code: [Select]
                        pthread_attr_init(&attr)/* ; */])],

Many thanks! I rolled back winpthreads from r652 to r631 and multithreading is back.

Seems like Msys2 current winpthreads r655 still has the multithreading bug.
I did a working generic git x64 compile for testing. I never started a win32 enviroment, sorry.

Anyone want to try FLAC for ARM64? (a.k.a. aarch64/ARMv8).  Not compatible with Android ARMv8.
