Description Samuel Owens 2006-03-22 12:16:57 UTC 
After successfully compiling SDL 1.2.9, I tried to compile SDL_image 1.2.4, but after successfully configuring, when I try to run make, I get this error:

I don't know why that file isn't there in the "stable" source code.  Especially since I compiled SDL, & SDL_image successfully on my machine at home (I'm on Computer Science lab computer now) last night
Comment 1 Samuel Owens 2006-03-22 12:23:08 UTC 
When I tried the CVS build, I get the same error.
Comment 2 Christian Walther 2006-03-25 04:24:37 UTC 
Looks like you don't have libpng? Although I'd expect configure to complain in that case...
Comment 3 Sam Lantinga 2006-04-12 10:29:09 UTC 
What platform are you running on?
If it's a UNIX platform, what's the output of: sh configure
Comment 4 Sam Lantinga 2006-05-01 05:19:14 UTC 
I think this may be fixed in subversion.
You can check out a snapshot here:
http://www.libsdl.org/tmp/SDL_image-1.2.5.tar.gz

Please reopen this bug if it's not fixed, and include the output of config.log
