The FreeImage source download has VC 2008 project files included. I convert them to VC 2010 and then build the FreeImageLib project. It builds fine but when I try to link to it I get the following errors:

From this post on stack overflow I would assume the problem is with using the VC 2008 project files but I don't know why? Any ideas what I'm doing wrong?

I ran into that as well, but can't remember the details. Are you mixing CRT versions? I think this came up when I rebuilt FreeImage but didn't rebuild all its dependencies.

Yes, it is the CTR. I knew the CTR was the problem many months ago but I had forgotten. Now the problem is that I can change the CTR to match my program (Multi-threaded DLL (/MD)) but then the compiler builds a separate DLL which means it's no longer a static library. I know I can't mix CRT types but I'm linking to several other static libraries without a problem. Confused?Posted Image

"

Multi-threaded DLL" doesn't mean that it will build DLL file. It will still build exelib or whatever you are building. Only difference from "

Multi-threaded" will be that your program will use CRT from DLL file and static CRT linked in your exe.

Yeah, I just realized I was accidentally building the entire solution. Anyway, the CRT was not the problem. I'm still getting those errors... I believe I had already compiled it with the right CRT a few months ago when I did it.

Surely someone must understand what is wrong? I've tried everything but I'm still getting the same debug output.

These errors are typical of mixing two different runtimes as noted above. I do not have any other explanation for the symptoms in the original post. Something you are linking together was compiled using a different runtime than the rest of the code. Note that although you cannot mix the /MT and /MD runtimes, you cannot mix neither /MTd with /MT nor /MDd with /MD.

Edit: Also, since you mentioned compiling it a few months back, it is possible for (possibly automatic) updates to modify the version of the runtime. If that happens, even a previously /MD compiled library could possibly show the same symptoms when linking it with a current /MD program (the same goes for /MT, /MTd and /MDd). I did not keep track of the MSVC 2010 update schedule but I faintly remember something like this happening in MSVC 2008 at one point.

Thanks to your response I realized it must be the other projects in the solution. I thought when I right clicked on a project and clicked build it was only building that project. However, it turns out that there was another sub menu which only builds that project but when I do that it says it needs the other projects. So I just had to set each project to Multi-threaded DLL and now it works perfectly! Thank you all for the help!

Actually problem is still not solved... Compiled prefect but all of the functions are returning null? Posted Image

EDIT: Just needed to initialize it. Posted Image
