Hello, I have been using allegro 5.0.10 for a long time and today I decided to give a try on a newer version.
I downloaded allegro-mingw-gcc5.3.0-x86-dynamic-5.2.1.1 from the main site, and after some trial and error I got my game compiling on this new version.
But one thing is bothering me: with the previous version I only had to include allegro-5.0.10-monolith-mt.dll in the game folder in order to run it, and now the executable asks for lots of dll files even though the old and new executable sizes are nearly the same.
Is there anything I can do to make it run with just 1 dll?

Edit:
Just found out: I was linking with all .a files rather than just the monolith one. However, it still asks for libgcc_s_dw2-1.dll and libstdc++-6.dll.

You'll want to download the zip file with 'static' in its name, and then additionally use the flags Edgar mentioned.
