After downloading redis source and attempting to make on Ubuntu server 28.04, it looks like I’ve got some dependencies missing:
cd src && make all
make: Entering directory '/home/kev/redis/redis-4.0.11/src'
In file included from adlist.c:34:0:
zmalloc.h:50:10: fatal error: jemalloc/jemalloc.h: No such file or directory
I found an identical post about this issue, with not building the dependencies. To fix:
make hiredis jemalloc linenoise lua geohash-int
sudo make install
That resulted in a clean install, ready to start redis-server !
