AIX build issues

[Anindya Mukherjee]

I have recently built the latest tmux git on AIX 7.1. The build had several issues:

Missing symbols for FNM_CASEFOLD, REG_STARTEND, and _PATH_DEFPATH

I had to rename the lines variable in tty.c

libevent2 also would not compile till I commented out

#define _LARGE_FILES 1

in event-config.h

It's now running after these changes. There are a couple small issues still. Is AIX still being supported? If not, I am interested in helping with coding/bug fixing. I have access to a couple of AIX boxes on which I can test, running AIX 7.1 with gcc 6.3.0.

Hi

I don't mind supporting AIX but I don't have access to it so I'm not able to test it.

REG_STARTEND will be important to fix properly, it is not enough to just define it to 0.

Thanks! Tmux being one of my favourite pieces of software, I'm interested in contributing specifically for AIX support but also more generally if I can do anything useful. I'm using tmux on Arch linux, AIX, and FreeBSD. I'll look into the significance of REG_STARTEND (trying to get a feel of the code right now).

Best,
Anindya

AIX's curses.h is the problem. Install the ncurses-devel rpm from IBM
and then tell tmux to build with it by adding
CPPFLAGS=-I/opt/freeware/include/ncurses to configure.

That's a great tip. I'll try it, thank you.
