We never have to recompile an RPG program because we added a field to a file. All RPG's access files via logicals and no logical is allowed to contain all fields by no listing any fields.

Recompile is the name of the game in unix and IBM i land.

Change a file (like add a field) and your RPG program broke? Recompile.

What your experiencing is DLL hell, but with a unix flare. They actually called it dependency hell on the unix side of things.

Subject: Dependency hell with cURL and libiconv.a

I have been playing on and off with getting several common Unix commands working on the system. Many seem to be working, but I get this when I try to use cURL (which impacts many other commands and scripts):

exec(): 0509-036 Cannot load program curl because of the following
0509-022 Cannot load module
0509-150 Dependent module
/usr/lib/libiconv.a(libiconv.so.2) could not be loaded.
0509-152 Member libiconv.so.2 is not found in archive
0509-022 Cannot load module curl.
0509-150 Dependent module
/opt/freeware/lib/libidn.a(libidn.so.11) could not be
0509-022 Cannot load module.

What bothers me is I think this means that libidn.a is looking at /usr/lib for libiconv.a and is finding the wrong version. I believe /usr/lib contains the libraries and dependencies provided by IBM, so I don't think I want to mess with any thing there.

What is the safest way to get libidn.a the right version of libiconv.a?
I want my cURL command to work without breaking stuff. I sort of get Unix dependencies and such, but not well enough (yet) to know a way to fix this. Every suggestion I see online from AIX gurus involves recompiling.

I hope there is an easier solution.
