Unable to build without SDL?

[specing]

Hi, upon doing ./configure --prefix=/data/users/specing/install/spar --without-bdb --without-mysql --without-opengl --without-postgres --without-readline --without-sound and fixing configure enough to make it pass, then running gmake all greets me with:

gmake -C src

1) uname -p prints processor product and not architecture 2) GNAT is not installed system-wide (but is at start of PATH) 3) Is SDL not obsolete and superseeded by SDL2?

OS is Gentoo GNU/Linux on amd64

4) the manual copy was cp src/spar_os-sdl-64bit.ads src/spar_os-sdl.ads

Looking into c_os.c I find redundant #ifdef on the first mention of SDL:

#ifdef FREEBSD
#include <SDL/SDL.h>
#include <SDL/SDL_video.h>
#else
#include <SDL/SDL.h>
#include <SDL/SDL_video.h>
#endif

That is correct.

The current version of the source code can be compiled without OpenGL (the Mesa library) but not without the SDL library (Simple Direct media Layer). I've not yet isolated the uses of SDL so it can be disabled using the configuration script. You will need to install SDL and SDL image version 1.2, if I remember correctly, first.

The redundant ifdef likely dates to a time when SDL was in a different location on FreeBSD but was later moved to the standard location, probably FreeBSD 9 or earlier.

[specing]

I see.

If it may help, I made some rough changes to be able to build SparForte without SDL and SDL_Image, see commit changes on specific branch.

[kburtch]

Merged Blady-Com changes to build without SDL.
