    Hi all, I’m making a post in hopes that someone can help me solve this linker error I’m getting while installing the Vrui VR Toolkit. I tried adding the -ffriend-injection flag to CSYSFLAGS in BuildRoot/BasicMakeFile as it was mentioned as a possible fix for undeclared functions in the README, but it didn’t seem to have any effect. Any help would be much appreciated.

    Some system information if you think it’ll be helpful.

    OS: Fedora Linux 36 (KDE Plasma) x86_64
    Kernel: 6.0.7-200.fc36.x86_64
    Compiler: g++ (GCC) 12.2.1 20220819 (Red Hat 12.2.1-2)

    The error reported during linking.

    The only thing I have seen similar to this is when I have tried to continue on from a failed build. The Make dependency graph does not see the need to recompile object files, so stale files are used during linking. One option is to remove the src directory before re-running bash Build-Ubuntu.sh.
