Deleted all the instances with "__fs" in file "LeoIpv4NetworkConfigurator.cc"

[LQZhong]

I tried to compile this project but failed with Error: no member named '__fs' in namespace "std".
So I change my compiler to gcc and delete all the instances with "__fs", to use the member std::filesystem in c++17, then it works.

In the root file of omnetpp, you can find a configure option in the config file, change it to gcc

Most likely, you didn't install the igraph package well. Remember to clone the dev branch instead of master branch.

How can I change the default compiler to gcc instead of clang in the configure.user file? I set "PREFER_CLANG=no", but it didn't work, did I miss anything?

after changing it, you need to re-configure and remake the omnet++ with command ./configure and make
