Maybe someone here can test this build https://git.lod.sh/PKGBUILDs/orca-slicer

It uses arch packages instead of the bundled deps except wxWidgets, because orcaslicer moved to the current dev branch for better wayland support. The next stable wxWidgets release should be later this year.

Some feedback from Bambu users would be great. My theory is, that bambu network stuff depends on openSSL 1.1.1… but I'm not sure.

@arslan2012 did you build in a clean chroot? preferably with pkgctl build -c

@lod tried https://git.lod.sh/PKGBUILDs/orca-slicer.git, makepkg exited with error

@lod - thanks, just wanted to confirm the fix is working, I am seeing compiler jobs working in parallel.

lod commented on 2026-07-08 14:58 (UTC)

@rlavriv fair enough, I will push an update later today.

rlavriv commented on 2026-07-08 14:43 (UTC)

@lod - you are using MemFree to estimate number of processes available but you should use MemAvailable. You are not taking into account caches etc. I have only 19GB of 32GB used, which MemAvailable reflects correctly as 13GB, but MemFree only reports 607MB.

@rlavriv works-for-me™ remove the the whole "CMAKE_BUILD_PARALLEL_LEVEL part" between cd and cmake and try again. (make sure you have enough RAM available)

rlavriv commented on 2026-07-02 16:06 (UTC)

Build process currently ignores -j flag from makepkg.conf, and only uses 1 thread when compiling the orca slicer itself.

lod commented on 2026-06-24 10:42 (UTC)

@gerliczkowalczuk if you interested, I also work on a build against system deps. Right now I got everything working except OpenSSL, CURl and wxWidgets. Upstream switched to the wxWidgets dev branch. wxWidgets should fix itself, when they move to the 3.4 stable later this year. I haven't really checked why Orca still depends on OpenSSL 1.1.1 yet.

I'll clean up the build today or tomorrow and if you want to, I will send you a mail for tests, feedback and help.

@lod Thanks for working on the update. If you need any help with testing or packaging, feel free to let me know.
