Current status as of RC-1:

All cherry picked commits have been merged, so just remove/comment any git cherry-pick line from the PKGBUILD.

The openSSL race-condition build failure is still there, and it's still random, so just retry if it fails once.

Previous update:

Current status as of beta 4:

Of the 3 cherry-picked commits, one was rebased (and is now 2c21a503b7861b6b993cc07f1433eb5a2d891a83), the other two have been merged.

So the 3 cherry-pick commands should be replaced with the single git cherry-pick 2c21a503b7861b6b993cc07f1433eb5a2d891a83. It currently builds fine with this.

Looks like SRCINFO didn't get updated.

FYI, build should be fixed now.

Rather than fighting with compiling the git version (there are now other issues than the three listed), I created a new package that will be updated for every release build published on GitHub:

There's 3 different issues affecting this package at the moment:

  • The current 0001-Fix-format-string.patch is outdated and should just be removed. You can remove the patch -p1 ... line from the prepare() step.
  • Until the linked PR ( has been merged (it hasn't yet at this time), it needs to be manually checked out (or applied via a new patch file) before attempting to build. I decided to apply it as a patch, so I don't need to rebase the branch on the latest master (and indeed the latest master has since moved forward).
  • Random race conditions during the vendored OpenSSL compilation lead to random build failures, but re-trying compilation can work eventually (it did for me). You might also try single-threaded build as others mentioned, but build will likely take forever (I haven't tried that).

For the first two fixes, here's a patch file that will update the PKGBUILD and local patch files:

@gyscos, so explain this to a layman. What is going on here? I am getting the same error. You sayin just keep trying to build it until it works?

gyscos commented on 2023-05-16 13:51 (UTC) (edited on 2023-05-19 02:07 (UTC) by gyscos)

For me, this now fails applying the patch:

==> Starting prepare()...
patching file src/slic3r/GUI/ImGuiWrapper.cpp
Hunk #1 FAILED at 460.
1 out of 1 hunk FAILED -- saving rejects to file src/slic3r/GUI/ImGuiWrapper.cpp.rej
==> ERROR: A failure occurred in prepare().

Essentially the patch is no longer required on the latest commits.

The remaining issues look fixed with

We could either take this PR as a patch, or checkout the branch directly.

The random failure when compiling OpenSSL is a bit annoying, but even on a 5900X (24 threads), it only affected me ~50% of the time, so re-running had a good chance of succeeding.

FYI this fails for me :

/home/felix/.cache/yay/prusa-slicer-git/src/deps/build/dep_OpenEXR-prefix/src/dep_OpenEXR/OpenEXR/IlmImf/ImfDwaCompressor.cpp:746:31: error: unknown type name 'uintptr_t'; did you mean 'intptr_t'?

This is reported on other projects as well, and is due to the GCC 13 release:

Not sure how I can handle that.

I tried -j1, but build run a day and not finished on Ryzen5.

sippiecup commented on 2023-04-13 15:35 (UTC) (edited on 2023-04-13 15:36 (UTC) by sippiecup)

The OpenSSL error is a race condition when doing multithreaded builds. Thats why it looks random or why Salamandar is unable to easily replicate it. It seems to reliably fail once you get past 8 cores.

A temporary workaround is to just set the number of threads in /etc/makepkg.conf to 1, or forcing -j1 when building this package.

Hope this helps.
