So, there are two ways of building kernel modules with GNU11 instead of gnu89 or C99.
1.) Do it in RTAI: https://github.com/NTULINUX/RTAI/commit/a649bbb40fad9299ba31285276d9204df2f222d9 2.) Do it in LinuxCNC: https://github.com/NTULINUX/linuxcnc/commit/a76b69f7e66f7a3831be655ea3dde4590502a175 The first commit builds both the RTAI math module (rtai_math.ko) and musl with GNU11 (thorough explanation in git message.) The second is more conservative; building only the LinuxCNC modules with GNU11. I think it makes more sense doing this in RTAI so everything just matches. I hacked away at the LinuxCNC sources to try and get a successful build going but now I'm getting this: Reading 205/205 dependency files Done reading dependencies MAKEFLAGS="" \ /usr/bin/python3.11 modsilent.py make KBUILD_EXTRA_SYMBOLS=/usr/realtime/modules/Module.symvers -C /lib/modules/4.19.294-rtai-amd64/build M=/home/ntu/linuxcnc/src CC=gcc V=0 modules make[1]: Entering directory '/usr/src/linux-headers-4.19.294-rtai-amd64' Building modules, stage 2.
