Building GPC with GCC-3.2.1 on Darwin
by Adriaan van Os 05 Jan '03

05 Jan '03

Here is a first report of my attempt to build GPC-20021128 with the GCC-3.2.1 backend on Mac OS X "Darwin". The GPC build is on a 1.1 GB 450 MHz PowerMac G4 running Mac OS X 10.2. Note: I am also trying to build GPC with an Apple-patched GCC backend (named "GCC3-1151"), but I will report about that separately. P r o b l e m 1 During Configure, conftest crashes, but the Configure process happily continues. This is not a GPC problem. The crash also appears if I try to build GCC-3.2.1 (without GPC). ********** Date/Time: 2002-12-24 14:40:01 +0100 OS Version: 10.2 (Build 6C115) Host: G4.local.

This is not a GPC problem either: same problems if I try to build GCC (without GPC). Being a C ignoramus, I simply commented away the offending lines (in order to at least continue the build process).

"Common" variables?
by Silvio a Beccara 02 Jan '03

02 Jan '03

Hi all, maybe it's a dumb question, but I can't figure out the answer by looking in the archive. I have a main program which defines and initialises some variables (double, integer, string, arrays). It uses a series of units. I want the units to share the same, initialised variables. For instance, if the variable "rho" is set to 0.01 in the main program, the unit "force" must have the same 0.01 value for the variable "rho". Thanks to all, best regards Silvio a Beccara
