5. 오류

5-1. jemalloc/jemalloc.h

make 과정에서 오류가 발생했다.

In file included from adlist.c:34:0:
zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory
 #include &lgt;jemalloc/jemalloc.h>

구글링하면 deps 하위에서 make hiredis jemalloc linenoise lua geohash-int 하라는 내용이 나온다. 그러나 이때는 진행 중 다음과 같은 문제가 발생했다.

make[1]: Leaving directory `/sw/redis-4.0.6/deps/lua/src'
make: *** No rule to make target `geohash-int'.  Stop.

그래서 아예 yum install jemalloc 한 후 다시 make를 실행했더니 성공했다.

Hint: It's a good idea to run 'make test' ;)
