Compiling in a MinGW environment: MinGW CRT compilation phase fails

[xgalaxy]

I'm attempting to run the scripts in a MinGW/MSys2 environement.

The MinGW CRT compilation phase fails:

I would certainly say that this seems like it really isn't the current git master. There was a fix for exactly this issue, in the master branch but not in the 5.x branch; see mirror/mingw-w64@25d5148.

[xgalaxy]

Its master from sourceforge. Is there a difference with that mirror?

[mstorsjo]

No, it should be the same as that mirror. Can you show what your copy of intrincs/rdtsc.c contains?

[xgalaxy]

My intrincs/rdtsc.c does not contain that change. Not sure what to say. Git is telling me I am on master. I did have the 5.0.3 tag checked out and checked out master when I got that error after realizing your git hash pointed to a revision only several days old.

At any point. I ended up swapping to the Docker version of martell's branch but getting a different problem there 😄 .

I'll close this ticket.

Does this version solve the AVX alignment with Windows 64?
See details in my comment here - msys2/MSYS2-packages#1209 (comment),

[mstorsjo]

Please don't hijack others' threads for asking unrelated questions.

As noted in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=54412, clang doesn't have this issue. You don't need to use the full llvm-mingw (which replaces all the components of the build chain) just to use clang, you should be able to install clang within MSYS2 while still using the rest of a normal GNU binutils based toolchain.

[RoyiAvital]

Is there a guide to install Clang on MSYS2?

Thank You.

[mstorsjo]

No idea, you need to ask some MSYS2 people.
