When I tried to build FleX on my Ubuntu machine, this error occured. Need help as I don’t know anything about compiling C++ applications…

So some notes.
I don’t know what those errors means(‘Error 1’, ‘Error 2’).
Those .a files are there so the compiler seems to lie to me.
Rest of it is kind of non-important, I guess?
