Could not build the VCMI under Windows (too many sections)

When I try to build the VCMI project under Windows usng CMake and MinGW I get this error:

Too many sections? That sounds familiar. Check this post:
[forum.vcmi.eu/t/compilation-with-code-blocks-and-mingw/522/1)
Specifically this line:

#3

I’ve created a pull request to fix this: github.com/vcmi/vcmi/pull/31 :slight_smile:

#4

That post is a bit outdated :slight_smile:
“Og” also works and should be used for debug builds.

Also we should add -s and -O2 or -O3 for release builds.
