I've been trying to get libpng to work in MSVC 2005 EE and when I try to build it and all I get is

Then I try the binaries and even after telling MSVC where the png headers are located (Tools - Options - Projects and Solutions - VC++ Directories = "C:\Program Files\GnuWin32\include" ) it still cannot open png.h When I manually copied the header files into the MSVC8 header folder I was bombarded with errors about headers not being able to be opened, int32_t not being recognized, and eventually I just restored my backup of that directory because it required that I change stuff that I wasn't sure I should edit. I just want to read and write to png's without having the overhead of some over featured image loading library. Most of them use libpng anyway. I also need to be able to load from my custom i/o stream.

Yeah, I had a bit of trouble getting libpng setup but IT CAN BE DONE! Unfortunately, I don't know exactly what the problem is with your currently configuration, although that is almost certainly the problem. Try going through the C/C++ and Linker options and see if any of them differ from what you normally use.

trying to build libpng alone produces this

Building pngtest causes a linking error since the libpng13d.dll failed to build.
And building zlib produces this error:

I don't see anything weird in the settings.

You are trying to build libpng with custom assembler optimizations - Visual C++ 2005 Express Edition doesn't come with assembler compiler.

Choose different configuration (without ASM in it).

How do I do that? Download a different version?

I also have the binaries and the versions with a setup program. I finally got the ones with a setup program a little further. Now I can find png.h (it put the directory in the wrong place in tools - options - vc++ dirs...) but I had to move the contents of the glibc directory out to the same dir as png.h and zlib.h then I got:

Paulius is probably right, there'll be some setting in project properties that's trying to play with ASM. I vaguely remember encountering a problem like this myself, and ended up tweaking settings for several days before getting it to work. So that you can avoid that, HERE is a copy of what I currently use. Hopefully, that'll get you where you want to be without the agonizing pain :)

Thanks man, what you sent me compiled successfully. Unfortunately I don't know where to go from there. I tried using it a test project and I got linking errors:

I gave it the directory of the output lib files in the linker options.

Ok, the problem is that VS cannot find the library file. Are you using the relative location of the lib? If so, you might have to add an additional ../ to the directory (a mistake I've often made). Otherwise, try using the absolute location as a sanity check.

Yes! It works, although not perfectly it is reading and writing pngs just fine. I had to add the lib files to the project to get past the linker error. I still get a linker warning though:

Are you using the multi-threaded debug DLL runtime library? I normally use the multi-threaded debug runtime, so there might be a conflict between the way I've built libpng and your project. I think you have to choose one and use it for all of the projects.

I had to disable /CLR and use /MTd instead of /MDd

I'm not sure if that will cause problems later, but it no longer has warnings.
*edit*
Found a better solution, I put my settings back and used the lib's from the binary install of libpng with the headers from your zip file. No errors or warnings.
*edit*
...except now it doesn't run since it can't find libpng13.dll, so back to the no /CLR solution...
