Execution impossible on w10 with a cross compiled libpng16-16.dll

Question

I have a problem, I build and link a windows application on linux for windows using mxe (x86_64-w64-mingw32.shared), the build an linking is working well. Then I copy paste all usefull dll (that are all cross-compiled, except x64-msvcrt-ruby230.dll, which I get from the official windows installer).

I tested my program with wine, no problem it works like a charme and I spot no difference with the linux version. But once I put everything in my test VM (windows10 64bit inside virtualbox) I receive the error message:

The procedure entry point inflateValidate could not be located in the dynamic link library D:\libpng16-16.dll.

libpng16-16.dll is there, and when I objectdump it (in linux):

objdump -x libpng16-16.dll | grep inflate

[3253](sec  1)(fl 0x00)(ty  20)(scl   2) (nx 0) 0x0000000000021b18 inflateInit2_

So apparently the symbol __imp_inflateValidate is present, so is there something I'm missing ? And does anybody know how to fix this ?

Thanks in advance

Just stumbled on the same problem. It turned out to be a confilicting dll file in the PATH environment varialble. try the ldd command to find out which dll files might be suspicious.

for instance, in my case, the culprit is the zlib1.dll from the Intel wireless software.


    E:\samples\sfmlSound>ldd sfmlSound.exe
            ntdll.dll => /c/WINDOWS/SYSTEM32/ntdll.dll (0x7ffee3e70000)
            KERNEL32.DLL => /c/WINDOWS/System32/KERNEL32.DLL (0x7ffee3030000)
            ...
            zlib1.dll => /c/Program Files/Intel/WiFi/bin/zlib1.dll (0x7ffed0f10000)
            ...

after resolved the conflicts, the program would load correctly.

For mzself it was because some dependancies of the official ruby dll was not consistent with the one compiled by mxe. I built ruby from scratch for windows on linux and it worked. — Laurent Jospin, Jan 29 '19 at 16:16

In my case I replaced the libpng16-16 file and that worked.

Replaced how ? The one I have here is the one built by mxe, where did you look for an alternative ? – Laurent Jospin Mar 17 '21 at 10:43
I did a search across c:\program files and found one in Inkscape. – CarbonMan Mar 17 '21 at 10:47

I just stumbled onto a similar issue while trying to run some code based on libpng16-16.dll. Apparently some build version of SDL_Image was broken: https://github.com/libsdl-org/SDL_image/issues/131, discussed in this article: https://discourse.libsdl.org/t/sdl2-image-fails-loading-libpng-on-latest-versions-when-cross-compiling/24494/

For me it worked to rollback to an older version and to make sure both libpng16-16.dll and zlib1.dll were both in the folder of the executable. (Of course together with the other required DLLs)

Versions of SDL_image can be found here: https://www.libsdl.org/projects/SDL_image/release/
