[erlang-questions] compiling linked-in driver on Mac OSX

[Jacob Vorreuter]

Ah, i386 I guess.  I tried that before but didn't format the error to see that my C code is just broken.  Thanks Max!

$ file erlexec
erlexec: Mach-O executable i386

$ gcc -o example_drv.so example_drv.c -arch i386 -fPIC -bundle -flat_namespace -undefined suppress -I/usr/local/lib/erlang/erts-5.7.5/include/
