Hi all,
I have had great success with the UCRT support I need for the project I am
working on.
But today I found out I also need winpthread support, which is currently not in
the kit
(gcc-8.3.0 based) I built.
I still have the script I used to bootstrap gcc-8.3.0 and associated runtimes
that are UCRT
based, I would just need to add in support for building winpthreads. Any ideas
on how to
best approach this?
If you just need winpthreads for direct use by some other code you're
building, you should be able to check out the mingw-w64 repo, enter the
mingw-w64-libraries/winpthreads directory, and build it (./configure
--prefix=<your_x86_64-w64-mingw32-directory>; make; make install).
If you need to have libstdc++ use this for its threading functions, you'd
need to rebuild the toolchain, building this after the mingw-w64-crt parts
but before building the rest of the gcc runtimes, and possibly change some
configure flag to gcc to make it use winpthreads (I don't know offhand
what flag that is).
