Well apparently Hannibal got the same error and could compile after make clean and clean-workspaces.sh.

mapkoc stated it was a problem with gcc even:

and the problem with gcc was with gcc 7.3.1+20180312-2 try compiling int main(){} , I got the same errors

Try updating gcc, version 8 is available too on Arch I heard.

ns do you still have this issue?

Does this error occur the very first time when you tried to compile it?

As far as I see it occurs when compiling with --disable-atlas and then not compiling with it anymore (or vice versa) and not cleaning workspaces in between.

In 21865:

Use pkg-config instead of sdl2-config

Resolves build issue on Arch Linux (and Arch-derivatives)

(Also forms part of a fix for Slackware-current builds)
