Building SDL_image against non-standard location libraries

SDL Development
1

I’m trying to compile SDL_image and link it against an SDL other than the one
already installed on my system. I built SDL without a problem against uClibc.
I’m configuring SDL_image as so:

env CPPFLAGS="-I/home/jbodnar/projects/mp3/build/libpng-1.2.3
-I/home/jbodnar/projects/mp3/build/zlib-1.1.3 -I/home/jbodnar/projects/mp3/b
uild/SDL-1.2.4/include"
LDFLAGS="-L/home/jbodnar/projects/mp3/filesystem/lib
-L/home/jbodnar/projects/mp3/filesystem/usr/lib"
PATH=/home/jbodnar/projects/mp3/build/i386-linux-uclibc/usr/bin:$PATH
./configure
–prefix=/home/jbodnar/projects/mp3/filesystem/usr
–enable-static=no
–with-sdl-prefix=/home/jbodnar/projects/mp3/build/SDL-1.2.4/src/.libs
–with-sdl-exec-prefix=/home/jbodnar/projects/mp3/build/SDL-1.2.4/
–disable-sdltest
–enable-jpg=no

when I try to compile SDL_image I get the following errors:

It appears that the build process can’t find my alternative SDL for both
showimage and libSDL_image.so.–

–disable-sdltest \

Does this line prevent the CFLAGS and LIBS being queried from sdl-config?
If so, that would explain why -lSDL doesn’t show up in the link line (hence
the errors you’re seeing)

Nope. Removing that line I still get the same thing. I also have the same
problem with smpeg (and I imagine any other library that depends on SDL). I
don’t think it’s an SDL problem, but rather a problem with autoconf, libtool
or perhaps even gcc.

I’ll continue to play around stuff and hopefully figure it out.

Thanks,
