Easier workaround would be

sudo ln -s /usr/lib/wx/config/gtk3-unicode-3.2 /usr/bin/wx-config-gtk3

and then install.

Edit: Wait, prusa-slicer doesn't work with wxWidgets 3.2...

@DCengineer

Did you get it working? mind sharing a patch or PKG build that works? I can't seem to implement it correctly.

Looks like the "fix" for now is to use a statically-linked wxWidgets. https://github.com/archlinux/svntogit-community/commit/143531d44a95acb3e84a64d5ab6f2e23ac8216a1

Looks like the latest wxWidgets update broke the build:

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES
  wxWidgets_INCLUDE_DIRS) (Required is at least version "3.0")
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake/Modules/FindwxWidgets.cmake:984 (find_package_handle_standard_args)
  src/CMakeLists.txt:52 (find_package)

The following patch fixes it:

UPDATE: segfaults on launch with PKGBUILD changes applied. Seems to be affected by https://bugs.archlinux.org/task/75332.

**Ok... ok.. I tried building it today and vwalah... it builds. not sure W.W.H.W.W. but it works. Hmmm. ok so ignore the rest of the message I have here. May as well keep it here.

Hey anyone else having issues building this? I I'm getting these errors:

-- EXPAT found in /usr/lib64/cmake/expat-2.4.8
CMake Error at CMakeLists.txt:466 (add_library):
  add_library cannot create target "libexpat" because another target with the
  same name already exists.  The existing target is an interface library
  created in source directory
  "/home/arcrog/AUR/3d-printing/prusa-git-new/prusa-slicer-git/src/PrusaSlicer".
  See documentation for policy CMP0002 for more details.

And this:

-- IGL found, using system version...
CMake Warning at /usr/lib64/cmake/CGAL/CGALConfig.cmake:92 (message):
  CGAL_DATA_DIR cannot be deduced, set the variable CGAL_DATA_DIR to set the
  default value of CGAL::data_file_path()
Call Stack (most recent call first):
  src/libslic3r/CMakeLists.txt:329 (find_package)


-- Using header-only CGAL
 

I've tried cloning a fresh build and still not building

I've tried rolling back cgal as seeing that warning there and even rolling back that expat and lib32-expat but no dice. *the cgal warning goes away but still stuck with the expat error.

Last thing here -I have the previous build of this app installed and running. I just can't get this to build again. Hope the information helps someone somewhere someday.

Ran into an issue after upgrading cgal to the latest version (5.4-1), I get error while loading shared libraries: libCGAL.so.13: cannot open shared object file: No such file or directory. Rolling back to cgal to 4.14.3-3 is fixing it just in case somebody else runs into the problem.

Same issue for a few days. I've opened an issue on Github yesterday: https://github.com/prusa3d/PrusaSlicer/issues/8126

@ArchBoxHero can reproduce. That's probably an issue upstream. It looks like they don't have at heart an all-time working master branch.

I get this to build but I cannot run it. I use I3WM.

Hey @Salamander Thanks for the push. Back to building fine. Also -I'm not sure if anyone has had any issues using both AMD/Radeon with <Nvidia cards using the prusa-slicer in general. See below for my setup. I swapped out the Nvidia card for another AMD/Radeon card and since then I have had no issues with slicing. I didn't have any special tweaks. I was using the AMD as my main display. Nvidia was just being used for gaming/rendering/etc. There are probably better ways to adjust the settings and libs used to have them play nicer together. Either way -the build works.
