Compiling an application using Lua

[cybermonkey342]

Hello,

I am stuck now. I can compile my program on Windows and Linux but not on MacOS X. It uses the units lua,lualib and lauxlib. I installed Lua from the source and it seems to work (at last the interactive mode works).
This is what I retrieve:

Any help is appreciated ...

I am stuck now. I can compile my program on Windows and Linux but not on MacOS X. It uses the units lua,lualib and lauxlib. I installed Lua from the source and it seems to work (at last the interactive mode works).

where to find lua* files?

[felipemdc]

Which bindings to lua do you use?

If you mean the libs, they are located in "usr/local/lib"

[cybermonkey342]

The units shipped with Freepascal.

[Laksen]

Try to look at the SDL units. For Darwin they have to use a linklib directive, it could be that you have the same problem?

[cybermonkey342]

Yeah, that's my other problem: I can't compile SDL applications, yet ...  I tried different things but nothing was successful.

[skalogryz]

what FPC version are you using?
what's the error with SDL?

[cybermonkey342]

FPC 2.4.0
I installed now SDL from source - at last Mac OS finds SDL now (which wasn't true with the framework), but:

Linking sdltest
ld: library not found for -lX11
An error occurred while linking
Error: Error while linking
Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted
Error: /usr/local/bin/ppc386 returned an error exitcode (normal if you did not specify a source file to be compiled)

Why in good heavens does SDL need X11 on a Mac??

To be frankly I want to compile my EGSL interpreter which can be found on: http://egsl.wikidot.com (which needs SDL AND Lua)

[Leledumbo]

Why in good heavens does SDL need X11 on a Mac??

Ask SDL developers
Perhaps because SDL was written before Carbon and Cocoa appear (CMIIW), and the developers thought that X11 will stay as Mac's windowing system.

Erm, the question was asked in a wrong way.
Why does SDL together with FPC need X11?
I can compile SDL applications with GCC without any problems and without the need of X11 libraries. I think that is an issue with FPC. On Haiku-OS it's just the same: compiling SDL applications with GCC is no problem, with FPC: X11 libs needed ...

Because the "x" and "xlib" units are in the uses clause of the sdl unit for all unix platforms, even though this is indeed not necessary.

[skalogryz]

Because the "x" and "xlib" units are in the uses clause of the sdl unit for all unix platforms, even though this is indeed not necessary.

wasn't it fixed in trunk?

[Jonas Maebe]

Not as far as I can see.

[cybermonkey342]

So it is enough to remove "x" and "xlib" from sdl.pas? And have other units to be added?
