ar.exe: could not create temporary file whilst writing archive: no more archived files

[wassupxP]

Hello, during usage of pre-built mingw, I encountered issue with ar.exe.

Issue: There seems to be an issue with the ar.exe tool in the msys package. I used x86_64-13.2.0-release-posix-seh-msvcrt-rt_v11-rev0.7z package variant.

Information:

• Compilation failures occur randomly.
• The error message points to a failure in ar.exe.
• The failure occurs during static linking - I didn't experience similar fail during dynamic linking.

Failure:

• msys2\mingw64\bin\ar.exe: could not create temporary file whilst writing archive: no more archived files

Am I doing something wrong? Is this known bug? It does not happen very often and on rerun it succeeds. Unfortunately as of now, I am not able to produce minimal example where it would be reproducible in at least 1/100 runs or so.

This bug was fixed in mingw-w64/mingw-w64@dbfdf802580c0d6b90b91995dab019f2a7787a8e.

Thank you! That is great news. By the way, do you know whether there is a way how to reproduce it locally? So we can test on rebuild that the issue is fixed? There are some reproduction steps in the comment, but I don't know where to find ib/libLLVMSparcCodeGen.a etc.

I hit the bug frequently when building mingw-w64's import libraries. Even then, the chance was like 1/10 though.

Thank you very much. Closing this ticket

You can reproduce the problem with commands from that commit. You don't need any files as the problem related to creating those files, not using them.

@mati865 @starg2 Hi guys, I don't know whether this is correct place to ask this. I rebuilt with --rt-version-v12 (whole build info is visible below). And with analogy of commands from the above mentioned commit I am still hitting the issue. (1:~1.3 milion tries - I kept it running during weekend).

Am I doing something wrong? I basically branched out from https://github.com/niXman/mingw-builds/pull/677 just modified expat version to newer one so build of mingw passes.

I don't know how those scripts work; was Binutils "bootstrapped" by building everything twice? Since the fix is mingw-w64 CRT you need to build a new toolchain with the latest mingw-w64 and then use it to produce a new build in which the Binutils issue will be fixed. IIRC, by default, those scripts download some old build and use it to create new releases.

Thank you, I will try the --bootstrapall param.

Yes, this is correct.

IIRC, by default, those scripts download some old build and use it to create new releases.

It's gcc 12.2 with mingw-w64 v10 now. It's not the latest, but far better than the previous default (gcc 8.1.0 with mingw-w64 v6).

Thank you for confirming that. So this bug won't be solved by https://github.com/niXman/mingw-builds/pull/677, but that is a prerequisite.
