so ,I delete the libSDL_image.a lib，and add the libSDL_image.so lib(they are both in the '/usr/lib/i386-linux-gnu' directory ).
it compiled success!

I would say to broaden this as I have dynamic loading of libjpeg and I am also getting failures.  The issue is on IMG_jpg.c:66, dlopen fails to find the .so for libjpeg even though I can access it fine.  I had a previous version of SDL_image and it worked just fine.

I will try to find out what is causing this later today.

Any luck finding the issue with the RC snapshot?

Comment 3 ahelper2 2013-06-03 08:34:55 UTC 
I just built the latest source and it does find and use the right version of libjpeg and libpng and links nicely. I just tested it and I am seeing images loading just fine, thanks. I did force what libpng and libjpeg were found for my previous builds of SDL_image, so I don't know 100% if the successful build is influenced at all from my previous efforts.  Otherwise, I would say it is fixed.
