I think so, for the following reason: when GPC will get qualified identifiers and/or function overloading, the translation Pascal identifier -> asmname can't be as simple as it is now. Therefore, it's not wrong to get used to do special declarations for variables one wants to use externally. What I find strange is the `external' in the example and having to repeat the declaration -- though I understand why it is currently necessary. I think in the long run, we should think of a better syntax for that. Frank -- Frank Heckenbach, frank(a)fjf.gnu.de http://fjf.gnu.de/ PGP and GPG keys: http://fjf.gnu.de/plan

unresolved references in libgpc.a
by Bernd Kurzan E1 14 Oct '98

14 Oct '98

Hello! After applying the new patch to the gcc-2.8.1 source code the gpc-19980830 compiler is now built by gcc-2.8.1 without any errors. When compiling the Pascal-programs in the "test" directory, however, most of the programs cannot be correctly compiled by gpc, because there are apparently some unresolved references in libgpc.a (see below an excerpt from the screen!). Is there a parameter file missing?

Yes, I think that's this problem. If you compile a unit with `-S', you'll find that global variables in the implementation (as well as global variables in a program) are `local' instead of `global' or `comm'. -- Frank Heckenbach, frank(a)fjf.gnu.de http://fjf.gnu.de/ PGP and GPG keys: http://fjf.gnu.de/plan

Note, ParamCount does not include the 0th argument (program name), unlike argc. (However, ParamStr(0) does return it.) You are using a newer GPC than 2.0, aren't you?

re:libgtk-use
by Mike Neuhaus 13 Oct '98

The problem is - gtk has no list of "extern" - definitions in one(!) file in the header - directory... and the link-process of libgtk needs many compiler-commandline-switches (...or use of gtkconfig). In libtk8.0 is this no problem. One (!) extern-list and simple link-process. Bud gtk has more from the good look and feel of free dynamic software. -- http://ekim.home.pages.de Mike Neuhaus ********PRO Heimerziehung heißt PRO Zukunft********** Die Heimerziehung bedarf nicht ihrer eigenen Abschaffung,sondern einer durch Innovation geprägten Reform
