Hi @leleliu008,

thank you for your report. Pegof doesn't currently officially support any other platforms than Linux. However, since this might affect security on all platforms, I have fixed the problem. The commit (https://github.com/dolik-rce/pegof/commit/06de1f60104b85f61c196aba8c349b2137f146e2) is currently on the devel branch, let me if it fixes the build for you (I don't have mac hardware to test and don't have time to setup virtualization/github actions/...). I will merge it to master in next few days.

@dolik-rce The commit (https://github.com/dolik-rce/pegof/commit/06de1f60104b85f61c196aba8c349b2137f146e2) fixed the problem.

@dolik-rce Due to @masatake have a big interest in this tool and he introduced this tool into uctags via PR, I'd try to make this tool usable on GNU/Linux, macOS, FreeBSD, NetBSD, OpenBSD, etc.

@leleliu008: The help is most welcome. I've noticed that you have already started fixing things in your fork. Feel free to send PRs, I'd really like to make pegof truly multi-platform, I just didn't have the time to support other platforms.
