Hello,vulkan tutorial and wanted to try if it’s possible to use vulkan in realtime somehow: the program basically uses vulkan through glfw after defining GLFW_INCLUDE_VULKAN. To make it work you need to load the vulkan shared library before the inclusion of glfw. As soon as the functions called execute vkEnumerateInstanceExtensionProperties it crashes with this message:

The stack trace tells me that Vulcan uses llvm11. That llvm clashes with cling’s llvm. You’ll have to hide all llvm symbols when linking cling, e.g. by passing -fvisibility=hidden and -Wl,-Bsymbolic to the compiler for the llvm built “as part of” cling.
Thanks for your reply! Unfortunately it doesn’t work. I add the command line options and it reports warning: -Wl,-Bsymbolic: 'linker' input unused which I have no idea about what it means and then report the same error:

isn’t there a comprehensive manual or something similar (I couldn’t find it)? I really know too less to even start to reason correctly and maybe I just messed up something trivial like maybe my llvm version is not the right one. If I recall correctly cling works with llvm-9, right?
Edit: Important: i’ve an Intel gpu and am using the distributed mesa driver (on a surface pro). It may be inaccurate but that could be the culprit according to this bug report . As soon as I have some time I’ll try to switch to a llvm-statically linked mesa driver and try on another workstation with an nvidia gpu and proprietary driver. I may be wrong though.

Hi,
Those are compiler flags for building cling. You should be able to pass them to cmake with -DCXX_FLAGS="-fvisibility=hidden -Wl,-Bsymbolic"; once that’s done you can build cling (and llvm and clang). If this doesn’t work / doesn’t make sense then please let me know how you built cling!
Cheers, Axel…
Hello,
previously I didn’t build it but downloaded the most recent binaries. I did build it now following this guide and using the script in which I added the specified option in the cmake line. Unfortunately cling still segfaults calling vkEnumerateInstanceExtensionProperties. As already said it’s not unlikely I missed some steps and, as always, thanks for the support.

This:
has your system lib’s LLVM call into cling, which is a proof that your build system modifications were not successful / sufficient. Please check with make VERBOSE=1 (if you use GNU Makefiles) that the llvm built as part of building cling (and not just cling itself) is indeed built with these flags.
