I am compiling a toolchain with buildroot, which I needed to add dahdi-linux to. After compiling for around an hour, the make process crashed at this error:
fatal error: linux/pci-aspm.h: No such file or directory
I had seen similar posts about this issue, so I replaced the folder that buildroot downloaded with the git-downloaded next branch of dahdi. Although, the same issue appears. If anyone would know why this happens I would be really grateful.
