stream编译出错信息：
[root@localhost stream]# make
gcc -O2 -DSTREAM_ARRAY_SIZE=1000000000 stream.c -o stream
/tmp/ccCGEF5F.o: In function `checkSTREAMresults’:

collect2: error: ld returned 1 exit status
Makefile:5: recipe for target ‘stream’ failed
make: *** [stream] Error 1
[root@localhost stream]#
解决办法：加上-mcmodel=large编译选项
[root@localhost stream]# ls
Makefile stream.c
[root@localhost stream]# cat Makefile
CC = gcc
CFLAGS= -O2 -mcmodel=large
all: stream stream_omp
stream: stream.c
$(CC) $(CFLAGS) -DSTREAM_ARRAY_SIZE=1000000000 stream.c -o stream
stream_omp: stream.c
$(CC) $(CFLAGS) -fopenmp -DSTREAM_ARRAY_SIZE=1000000000 stream.c -o stream_omp
clean:
rm -f stream *.o .depend *.*~ stream_omp
