Redis build failure

Question

I'm attempting to build redis on my aws linux server in order to get access to the redis-cli and connect to my redis instance which is also running successfully in aws.

my gcc is:

gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)

I downloaded the source and started the build:

wget http://download.redis.io/redis-stable.tar.gz
tar xvzf redis-stable.tar.gz
cd redis-stable
make distclean      
make

It built the dependencies and then gave me this:

gcc -std=gnu99 -Wall -pipe -g3 -O3 -funroll-loops  -c -D_GNU_SOURCE -D_REENTRANT -Iinclude -Iinclude -o src/tsd.o src/tsd.c

     fp = log_to_stdout ? stdout : fopen(server.logfile,"a");

...and a lot more

I assume that I must have done something wrong as this is code that undoubtedly builds for everyone else. I'm a java developer with little to no c background. Any pointers will be appreciated.

Answer 1

Appears that gcc >= 4.9 is required to build redis 6x ...

Answer 2

Problem here is latest Redis version(6.0.7) depends on _Atomic which is not supported in older gcc 4.8.5. One can also compile latest Redis code with clang if updating gcc version is not possible.

$ cd redis-stable
$ CC=clang make
