: Perhaps I should have mentioned this in the readme. On some systems

Is it safe to remove the redundant comp1.so that is created in this
case? Also, is it possible to have the Makefile not install it if its

I was only explicitly loading it in an attempt to narrow down the cause
of the problem.
: Perhaps the output of zmodload should include the
: statically linked modules as well (with some indication that this module is
: static). This would give the user a more clear picture.
That would be a good thing :)
: The IRIX crash is probably caused by the duplication of the comp1 module.
The IRIX version loads the comp1 module on startup itself; this leads me
to believe that comp1 is not builtin to the IRIX binary. When it
successfully loads the comp1.so, it seg-faults; without it it carries on
: Deltochar have a similar problem, it wants to use the zmod symbol exported
: by the zle module. The symbols defined by a module can be discovered using
: dlsym even on these systems, so we may find some way to overcome this
: limitation. I think it is possible to do that with some script-generated C
: code. For that we also need a list of exported and imported function for
: each module and for the main binary, which is also needed for dynamic
: loading on AIX. The imported function list is hard to portably generate
: automatically, so these lists will probably have to be maintained by hand
: (with the help of a script, which can generate this list automatically
: using nm, ld or some other tool on an OS I have access to).
I hope it all comes together soon!
