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.
