Looking at all the replies to this, I think I need to apologize to everyone. I should have been more specific in what I was asking for, but I was afraid to because I was afraid of what people would think of me if I told them what I was doing. But I guess I have no choice... I write assembly so all my programs are written in assembly (GoAsm/GoLink for Windows and NASM/ld/ar for Linux). So go ahead and hate me. Are you finished? Ok, I install nothing because there is no need to install anything on an assembly level. Everything I need is in the DLLs and (hopefully) SOs. So when I say that ld (which is the linker part of GCC) reports libcdlua53.so has an undefined reference to 'lua_newuserdata', I have no idea (yet) why ld would look for data or a function that I'm not using, not even indirectly that I'm aware of. So what is lua_newuserdata? What functions use it? I didn't know which of the lua SOs I need so I included all of them, but deleting the reference to libcdlua creates a different error, and deleting that include leads to another error so I deleted all reference to any lua libraries. Now everything links. But I do have a program I haven't translated to Linux yet that uses the built-in Lua IDE, so I will run that and see what dependencies it says I need, instead of guessing. If the issue occurs again then, I will bring it up again then. I use IupMatrixEx, so to see it missing worries me. Is it actually missing or is it not supported in Linux? Maybe I shouldn't worry? I see freetype for Windows, and I'm betting that was to make IUP portable because freetype (or its equivalent) is built-in to Linux and Mac. But I need to be sure in case I do have to "install" something on my own that I didn't have to do in Windows. Nothing is a show-stopper here, I just need more info.
