I get the following error when trying to build:

==> ERROR: Cannot find the git package needed to handle git sources.

I added this in build() after cd "${srcdir}/PrusaSlicer" to make it use the included qhull:

Can't get it to build. It complains about issues linking to qhull - which is installed, but recently updated.

Update: Downgraded qhull to the previous version. Builds fine.

I had to add this to get it to build:

I'm not entirely sure what this does but I found out about it in this AUR comment

@mikelkook thanks for the PR upstream.

The flag has been fixed. Sorry, my workstation is on ubuntu now so the updates may be a bit slow to come. I need to setup a small Archlinux container for that.

Pull request #4738 just got merged. All that's left is to update the build flag in the PKGBUILD.

this works, sorry mikelkook I was tired and inverted the flags by setting DSLIC3R_STATIC at ON, not DSLIC3R_PCH.

I confirm that the branch of mikelkook with DSLIC3R_PCH=ON works for me. Can we update the AUR?

Thanks mikelkook!

@mrsinham: Did you really set the compile flag -DSLIC3R_PCH in Line 55 in the PKGBUILD from OFF to ON? Cause that's exactly the error I'm also getting when it's set to OFF.

With the fix of mikelkool I am going further in the compilation but still in error :

Got the same, but the real error is some lines above. I made pull request #4738 which fixes the compilation error. Until this gets merged one could temporary set the url in the PKGBUILD to 'https://github.com/charlie89/PrusaSlicer#branch=fix-build-on-arch-linux'.

The other issue is that this PKGBUILD currently builds with -DSLIC3R_PCH=OFF, which results in various compilation errors, setting this to ON makes the compilation succeed.
