Okay am I missing something? There is no autogen file or anything to compile anywhere in your cloned github directory
nvm.. had to dig pretty hard on your github.
cd src/
git clone
https://github.com/bitcoin/secp256k1mkdir obj/crypto
make -f makefile.unix
your shit doesn't compile
g++: internal compiler error: Killed (program cc1plus)
Please submit a full bug report,
with preprocessed source if appropriate.
See for instructions.
makefile.unix:200: recipe for target 'obj/init.o' failed
make: *** [obj/init.o] Error 4
that error because your system lack of memory, so basically talk your system is shit
