I’m a (fairly) new Pascal user, and I am trying to help a friend port a Digital Pascal application to GNU. I am now looking at one of two “big (?)” programs, which contains about 3000-4000 functions/procedures in about 40 modules. Currently, this is organized as follows: There is one “environment” module (which every other module “inherits,”) containing type definitions, global variables, and a list of ”[global]” functions and procedures, declared (here) as “external”. All functions/procedures used in the set of modules are [global], and they are (or at least seem to be, at this point,) more or less randomly distributed over the 40 modules, (so that a proc/func from any module might be calling a proc/func contained in any other module.) I have tried using the unit / uses syntax, (specifying that each unit “uses” this environment module,) but I still cannot get these units linked. The compiler is complaining about several hundreds of “undefined references” – I am now assuming that it is expecting the “imported” modules to contain the code for all of the procs/funcs called by each unit, rather than just the “external” definition. Is this correct, or might I be misunderstanding what is happening? (I am currently running gpc-20040516, gcc-3.3.3, on Suse Linux. I had previously run some tests using the last Gnu Pascal release system running on cygwin.) I am hoping to avoid having to analyze dependencies and completely re-organize the modules. Is there any other way? Thanks for your help, - Inga Matthews
