compilation error #757

Open jihwanK opened 6 years ago

jihwanK commented 6 years ago

Hi, I just tried to run a makefile but I got this errors:

gcc -Iinclude/ -Isrc/ -Wall -Wno-unused-result -Wno-unknown-pragmas -Wfatal-errors -fPIC -Ofast -c ./src/gemm.c -o obj/gemm.o
cc1: error: invalid option argument '-Ofast'
cc1: warning: unrecognized command line option "-Wno-unused-result"
make: *** [obj/gemm.o] Error 1
AmmarkoV commented 6 years ago

Open your Makefile in root directory and change line OPTS=-Ofast to OPTS=-O0

Also out of curiosity what gcc version are you using ( what is the output of gcc --version ? )

Also encountered this problem, my GCC is 4.4.7, the modified make other problems: gcc -Iinclude/ -Isrc/ -Wall -Wno-unused-result -Wno-unknown-pragmas -Wfatal-errors -fPIC -O0 -c ./src/gemm.c -o obj/gemm.o Putting child 0x011c7f20 (obj/gemm.o) PID 16820 on the chain.

oh! I also met the probelm,Did you solve it?

baimin1 commented 5 years ago

me too . I fix it by using:

yum groupinstall "Development Tools"

then gcc (GCC) 4.8.2 can do it.
