dynamic loading on SunOS 4.

dynamic loading on SunOS 4.

[Tanaka Akira]

I found a dynamic loading problem as following on SunOS 4.

Z:akr@is27e1s02% zsh -f
is27e1s02% echo $ZSH_VERSION 
3.1.5-pws-25
is27e1s02% echo $OSTYPE 
sunos4.1.4
is27e1s02% zmodload complist
ld.so: Undefined symbol: _minfo
zsh: exit 127   zsh -f
Z:akr@is27e1s02% 

I suspect that a shared object cannot refer other shared object's
symbols on SunOS 4.

I've been slow replying to this, partly because I didn't think dynamic
loading worked on SunOS 4 at all.  But this problem is presumably generic
to all systems without a working RTLD_GLOBAL.  The most obvious way round
it is to arrange for complist and zle to share symbols via comp1.c,
like zle and compctl already do.  Maybe that's not too hairy?

Yes, I've been thinking about this, too. I'll have a look at it, but
don't hold your breath.
