Marco S Hyman, Stephen J. Butler,
thanks a lot! Indeed, stupid me, I was missing "-L.". I used to use it (as
I copy-pasted above) but somehow when hitting up arrow in terminal I must
have accidentally deleted it. Now it links! So to recap, properly naming
the library ("libpython33.so") and compiling with:
gcc embed.c -I./include -L. -lpython33
works! Thank you so much people!
The problem is, as Stephen points out, the executable doesn't run:
Reason: image not found
Trace/BPT trap: 5
I will read the links about frameworks now...
