Also, like all macOS apps at this point, the default build is 64 bit. If you want a 32 bit build, you can specify the required architectures to the configure script:
./configure --enable-universal=i386
I compiled both ways, for 32 and 64 bits, but the app that comes out looks the same... how can I check in the guts of if to see if it is 32 or 64? When we get the released compiled versions, that's given in the name, but other than that, I wouldn't know how to differentiate, any ideas?
