Arch Linux User Repository

Hi I am having trouble compiling / installing the latest git version. Error is as follows:

[ 17%] Performing build step for 'dep_FFMPEG' LD libswscale/libswscale.so.8 GEN libavcodec/libavcodec.ver AR libavcodec/libavcodec.a LD libavcodec/libavcodec.so.61 /usr/bin/ld: /tmp/ccWj8cmF.ltrans7.ltrans.o: warning: relocation against mask24b' in read-only section.text' /usr/bin/ld: /tmp/ccWj8cmF.ltrans7.ltrans.o: relocation R_X86_64_PC32 against undefined symbol `mask24l' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status make[3]: *** [ffbuild/library.mak:119: libswscale/libswscale.so.8] Error 1 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [CMakeFiles/dep_FFMPEG.dir/build.make:86: dep_FFMPEG-prefix/src/dep_FFMPEG-stamp/dep_FFMPEG-build] Error 2 make[1]: *** [CMakeFiles/Makefile2:916: CMakeFiles/dep_FFMPEG.dir/all] Error 2 make: *** [Makefile:91: all] Error 2 ==> ERROR: A failure occurred in build().

It is the only error I can see so far, is there some dependency - I am assuming FFMPEG related - I am lacking or something else?

Hi! I downloaded your pkg and built it, just had to chagne dep harmonyos-sans-git into ttf-harmonyos-sans - it seems the other one no longer works. First print sent from arch is now going, thanks a lot !! :)

You also need:

gst-plugins-bad gst-libav

in order to get the video feed from the printer to work in Bambu Studio.

Fixed upstream with latest master as of 7/10/23

Current master branch won't build on GCC 13 without the patch provided below

Subject: [PATCH] Fix mcut for GCC 13

GCC 13 requires an explicit #include <cstdint> for the std::uint32_t  data type used by this file. Adding this include allows for the whole project to successfully be compiled on GCC 13

Opened issue 2006 in upstream

I'm starting to work on the GCC13 issues. Opened issue 1940 (https://github.com/bambulab/BambuStudio/issues/1940) in upstream.

Hey gang, @hak8or and @ajacocks thanks for the headsup and all that. Just confirming the same issues with a segmentation fault present day when trying to start. And in my journalctl I am getting this:

Jun 17 19:20:41 username kernel: bambustu_main[2787535]: segfault at 10 ip 00005607cc295831 sp 00007ffe4df18ce0 error 4 in bambu-studio-bin[5607c8fdc000+3563000] likely on CPU 2 (core 2, socket 0)
Jun 17 19:20:41 username systemd-coredump[2787586]: Process 2787535 (bambustu_main) of user 1000 dumped core.

Thanks for the research. I’ve spoken with the Bambu folks, and they say that the current main branch and production release are known to be broken.

Sadly looks like both this and the "bambustudio" AUR package suffer from the same problem for me. On a clean install (meaning ~/.config/BambuStudio was deleted), the software does start, but after logging in and letting it install the network plugin, it will fail with the following stackdump according to gdb;

Trying again via closing the tool and starting it back up gives this;

Looking around on github, I see this was noticed and seemingly acted on (https://github.com/bambulab/BambuStudio/issues/760), but sadly many unrelated bug reports/discussions happened in the thread so it's very hard to follow. I think the attempted fix is present on the 1.4.2 branch, which the bambustudio AUR package is not on (it's on a tag further back), but I did try with a pkg-build based off these and got no luck.

Thankfully I do see quite some activity by BambuLabs on the master branch to get the github CI building for linux, which is great, but since this issue persists in both master and the 1.4.2 branches, I assume it will remain unfixed for a while. The appimages I see, while do not crash, sadly are extremely unperformant (it's a slideshow) on Linux (for me, on a 1070 GTX and 2700x), to the point I can't do anything in the slicer besides print.

I seem to be running into an issue with finding tbb. I have tbb installed, and have also tried installing intel-oneapi-tbb, as well as intel-oneapi-basekit, and neither of them seem to have fixed it. I also attempted to set my TBBROOT env var and again, no help. This doesn't happen with the bambustudio non-git package, however i get the crash with network features which i assume will be fixed here before it's fixed in the base package

CMake Error at cmake/modules/FindTBB.cmake.in:198 (file):

CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

Without TBBROOT set, it correctly looks in /usr/include/tbb, which exists for me, but again, does not include the tbb_stddef.h file.

I resolved my segmentation fault by removing ~/.config/BambuStudio, which is automatically recreated. I recommend backing it up and copying in individual files. I think that the language or network could be to blame, but that is just a guess.

While this enables getting to GUI, it then crashes after installing the network manager tool.

Edit: instead of removing your entire config (including profiles), you can remove just the network plugin, which is what causes the segfault. It will safely reinstall and bambu studio will boot:

rm -rf log/ plugins/libbambu_networking.so
