Compilation problems.

I use debug flag for autogen. It's not my error, because on master the same error occur. Is the a way to suppress this single error? Compile this file with different autogen options set and copy an object file? Maybe better approach?

Which distribution?

In case of Debian; Debian Experimental has liblua5.4-dev package. Once you have that installed, you don't need to compile lua as part of freeciv build.

OpenSUSE Tumbleweed

liblua5_3-5 | The Lua integration library

Above one is installed.

libluajit-5_1-2 | Library for JIT Lua compiler

Above one too.

But I don't have header installed and it isn't available in setup repositories.

I have an question. Where could I find autogen/configure documentation? When calling ./ --help, it not display help. I will compile lua in different directory and copy object files.
