Question

I was trying to compile Redis 2.6.4 on CentOS 5.8 but I was getting the following error after running make

zmalloc.o: In function zmalloc_used_memory':
/root/redis-2.6.4/src/zmalloc.c:223: undefined reference to
__sync_add_and_fetch_4′ collect2: ld returned 1 exit status make[1]:
* [redis-server] Error 1 make[1]: Leaving directory `/root/redis-2.6.4/src’ make: * [all] Error 2

I also tried CFLAGS= -march=i686 in the src/Makefile but did not work. Actually, I don’t know where to put it. I put at the top of the file.

Answer 1

Ok, I got it done. I run the following command which seems worked correctly (though later I need to install tcl8.5).

make 32bit
