I have seen GCC 8 work at least on some Linux distributions. What OS / version do you see this issue on ?

ubuntu 18.04 , compile openwrt ,package version at : 6411e77

Hmm, my Ubuntu 18.04 ships with GCC 7.4.0 which compiles PTLib fine and I don't see a GCC 8 packet in the Ubuntu repo.
Also, I don't see where https://github.com/openwrt/openwrt is using PTLib.

It seems that the version at that time is indeed not compatible with gcc8.0 and above. Many glibc functions have been abandoned.

Please update to the current version.
