tmux compile failure
I love me some tmux.
However sometime between CentOS 5 and CentOS6 something broke and tmux no longer compiles. Here’s my error message:
...
control.c: In function ‘control_callback’:
control.c:62: warning: implicit declaration of function ‘evbuffer_readln’
control.c:62: warning: nested extern declaration of ‘evbuffer_readln’
control.c:62: error: ‘EVBUFFER_EOL_LF’ undeclared (first use in this function)
control.c:62: error: (Each undeclared identifier is reported only once
control.c:62: error: for each function it appears in.)
control.c:71: warning: implicit declaration of function ‘time’

make: *** [control.o] Error 1
[root@testcentos6 tmux-tmux-code]#
After some googling people refer others to utilize the latest version of libevent. Well, I wasn’t using the latest I was using whatever comes with the CentOS repos. So I decided to fix this by removing those:
yum remove libevent libevent-devel libevent-headers
Then compile my own libevent. I don’t do anything out of the ordinary on this server so I’m not even sure if anything I use depends on it:
wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar xf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
Their README was very basic, so rock it:
./configure
make
make install
I then returned to my tmux source:
cd /usr/local/src/tmux-1.7
make clean
make
make install
Then another issue:
[root@testcentos6 tmux-1.7]# tmux
tmux: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory
Luckily this error has been seen before. After another quick google:
ln -s /usr/local/lib/libevent-2.0.so.5 /usr/lib64/libevent-2.0.so.5
tmux
AWESOME!
