Dear sir,

I have an error message when running script.

/home/monkey/Kangaroo2# make gpu=1 ccap=20 all
g++ -DWITHGPU -m64 -mssse3 -Wno-unused-result -Wno-write-strings -O2 -I. -I/usr/local/cuda/include -o obj/SECPK1/IntGroup.o -c SECPK1/IntGroup.cpp
g++: error: unrecognized command-line option ‘-m64’
g++: error: unrecognized command-line option ‘-mssse3’
make: *** [Makefile:80: obj/SECPK1/IntGroup.o] Error 1

Any suggestions ? Please.
