Debugging load time error in C++ SDL2 program compiled with VS2015 on Win10

Question

I\'m writing a project in C++ with SDL2 on 64-bit Windows 10 using Visual Studio 2015. I recently purchased a new Windows 10 laptop and cloned my project from github. My pro

This is by no means completely reliable, but you can give it a try. It requires dumpbin.exe, which is included with Visual Studio.

First, get a list of dependent DLLs for your program, resolved against your path:

del dlls.txt
for /f %d in ('dumpbin /dependents Questless.exe ^| findstr /ic:".dll"') do @echo %~$PATH:d >> dlls.txt

Then get the bitness of each:

for /f "delims=" %d in (dlls.txt) do @echo %d & dumpbin /headers "%d" | findstr /c:"machine (x"

This will produce output like:

C:\Windows\System32\kernel32.dll
            8664 machine (x64)
C:\programs\ed23\bin\hydra.dll
             14C machine (x86)

Note that this is incorrectly using the kernel32.dll from System32, rather than the WOW6432 one, so it shows that as x64. That's because it just used the path, when the Windows loader will actually use the WOW6432 mapper, SxS, the application manifest, and only fall back on the path if none of those resolve the dependency. It also doesn't find dependents of dependents (you could script recursing through the dependents, but be sure to filter out duplicates), and of course doesn't know anything about run-time explicit dynamic loads.

Nevertheless, it's a quick way to get a short list to check, and might identify your problem.
