IMO the easiest way to handle the setjmp/longjmp issues for those that have to use the LibJPEG and/or LibPNG backends would be to simply skip the xjmp functions altogether and throw proper C++ exceptions from the error handlers...This might require (re)building the backend lib (and possibly linking statically) with C++ exceptions enabled on some platforms but this might prove to be easier in the end/long run...
I think we should get rid of those backends entirely. Phil stated interesting use cases in a different thread, that might not be accomplished with these libraries. Additionally to that I made bad experiences with libpng and non broken but somehow not conformant png images. There are alternatives to using libpng and libjpeg: * LodePNG: http://members.gamedev.net/lode/projects/LodePNG/ * STB_Image http://nothings.org/stb_image.c I havent used the stb jpeg loader, but I switched to lodepng for the non-gil code.
