I have been trying to use some simple Lattice C GEM ruotines. Everything compiles fine, but when I try to link, all of my GEM calls turn up as undefined symbols. I am linking with the C.LNK file that came with the package with the line for the GEM library uncommented. In the linker map fille it lists all of the symbols it takes out of the other libraries and the name GEMLIB.BIN but the symbols are still undefined. I get a .PRG file after the link, but it doesn't run. HELP! I have sent a letter to Metacomcos tech support along with my registration number but have not received a response for quite a while. Can someone who has been successful with linking to GEM libraries please tell me what to do??? thanks for any replies in advance, Bob

I spent about 10 hours figuring this one out. The problem is that you are
compiling with the -n options that allows routine names greater than 8
characters in lenght. All of the names in GEMLIB.BIN are 8 characters long.
So there are two solutions to this problem. One is to allow use the first
8 characters of any GEM call. Another solutions which I've been using is to
redefine the GEM calls. I have a include file called GEMDEF.H that looks
something like the following:
#define APPL_INIT appl_ini
#define FORM_ALERT form_ale
etc.
Anyway I hope this helps.

I am linking with the C.LNK file that came with the This is an annoying feature in lattice if you dont know about it. In the pre 3.4 lattice the gem library was compiled with the 8 character symbol limit so "appl_init" is "appl_ini" . This is ok unless you use the -n option in your own progs. So don't use the -n option In 3.4 If I remember things are reversed so "appl_init" really is "appl_init" and you have to use use the -n option. I wrote to the net a while back about the new lattice linker bombing out. I've seen no replies.
