error only building static version on MSYS2/MINGW64

[gaaned92]

Environment : W10, msys2/mingw64 updated to last version LCMS2 version : master 2.12-46-gc6d1c9c build procedure:

./configure --prefix=$destination --with-threads 
make
make install

When building above LCMS2 version, I get this error message:

last working version is d677b13

It seems you are forcing pthread (using --with-threads) but you have not the library installed. Try to let configure to do its job of auto-detection:

./configure --prefix=$destination ; make ; sudo make install

That should do the trick. Another option on windows is to use visual studio.

I verified that the library is installed and moreover, in same configuration, I can build commit d677b13. After that, certainly something was badly modified in the configure file.

Reopened for inspection. Thanks for reporting.

Sorry, I can't reproduce the issue. I have download & installed MINGW64, following https://www.msys2.org/ Then I installed pthreads https://packages.msys2.org/package/mingw-w64-x86_64-winpthreads Then I used the zipped head https://github.com/mm2/Little-CMS/archive/refs/heads/master.zip unpack and then ./configure --with-threads make make check All works fine for me. Checked 2.12 official and also works fine.

[gaaned92]

Thanks for the verification. So certainly a problem in my installation. I will try to reinstall pthreads from scratch and use the zipped head and will report.

[mm2]

Great. Please let me know, I will keep the issue open until I got your feedback.

[gaaned92]

I reinstalled pthreads .

2.12 builds ok with flag --with-threads 2.12-46 cannot be built with above flag, but it builds without this flag.

The two versions have different configure files, but due to lack of understanding the commands, I cannot identify the reason of the problem.

I have two possibilities:

• stick with 2.12 or 2.12-23-d677b13
• build without flag

I am going to use second option. Thanks

Cannot reproduce. closing it
