Hello,
can anyone help me with OpenLibrary()? Why this 32 bit dll cannot be opened in 5.70 LTS x86?
This will print "0":
Code: Select all
Debug OpenLibrary(0, "e:\dev\x264grabtest\libx264-157.dll")
I can open another library, but not this one.
Download dll:

The dll have dependencies, try SetCurrentDirectory() before you open it..
Code: Select all
SetCurrentDirectory("e:\dev\x264grabtest\")
Debug OpenLibrary(0, "e:\dev\x264grabtest\libx264-157.dll")

Hmm, still not work. Is there any way how to show some error message, why it is not opened?

For libx264-157.dll needed libgcc_s_dw2-1.dll.

You can use depends.exe 'Dependency Walker' to see that LIBGCC_S_DW2-1.dll is needed beside the LIBX264-157.dll

Also libwinpthread-1.dll is needed by libgcc_s_dw2-1.dll. I used 'Dependency Walker' and I finally can open that dll. Thank you guys.
