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’:

stream.c:(.text+0x144): relocation truncated to fit: R_AARCH64_ADR_PREL_PG_HI21 against `.bss’

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

[root@localhost stream]#
