Internal compiler error on Unixware
by Theo Carr-Brion 05 Sep '01

05 Sep '01

I am trying to compile gpc on Unixware 7.1.1 with gcc 2.95.3 and gpc 20010623. These two versions do not seem to be important. I have installed the latest versions of binutils, grep, sed, texinfo fom www.gnu.org and have versions of gnu make and patch. I can compile these utilities and gcc. I get the following error compiling the gpc rts: ../.././xgpc -B../.././ -c -I. -W -Wall -Wpointer-arith -Wwrite-strings -Wmissing-prototypes -Wmissing-declarations -g -O2 -DRTS_RELEASE_STRING="'`cat /usr/local/src/gcc-2.95.3/gcc/p/rts/rts-version`'" --unit-path=/usr/local/src/gcc-2.95.3/gcc/p/rts --automake string.pas string.pas: In function `Memcompcase': string.pas:211: Internal compiler error in `add_bound_info', at dwarf2out.c:7383 Please submit a full bug report. There is no core dump. Can anyone help me please? Is there any other information I can give? Theo Carr-Brion

Well how do you guys debug GPC when you are testing new features you have written? ----------------------------------------------------------------------- C. Adam Oldham Marconi Commerce Systems Inc.

debugging the gpc executable
by Oldham, Adam 04 Sep '01

04 Sep '01

At the risk of sounding increcibly inept.... For those of you that have modified the GPC source, how do you go about debugging it? I've built it with debugging symbols, but GDB doesn't recognize any of the functions names, I've never had this problem before.... Any suggestions?

How can I tell the Compiler, that the source of an unit is at the same place as the main-source, when I invoke it from somewhere else?
by michael paap 04 Sep '01

Hello, can anyone please help me with the following: I 've got a Directory, where there is the sourcecode which shall be compiled, and where the executable has to go. But I have to invoke gpc from a different directory. This works fine... i am doing it this way: /usr/local/bin/gpc -s --automake /home/michael/WebAssign/data/1612/compile/testeSchlange.pas -o /home/michael/WebAssign/data/1612/compile/executable This compiles "testeSchlange.pas" and produces a file named "executable" in the directory /home/michael/WebAssign/data/1612/compile/ But now I want to use an unit, which is not precompiled. The sourcecode of the unit is in the same directory as the sourcecode of the main-program. If I do the same as in the first case, the unit is not found. So tried it like this: /usr/local/bin/gpc -s --automake --unit-path /home/michael/WebAssign/data/1612/compile/ /home/michael/WebAssign/data/1612/compile/testeSchlange.pas -o /home/michael/WebAssign/data/1612/compile/executable But this does not work, too. So, can anyone give me the right syntax? What is the difference between --unit-path and --object-path? Greetings, Michael Paap

compiling gpc

I am trying to compile gpc20010623 with gcc 2.95.3 but the compiler complains about the following. in gcc/tree.h: extern int lang_decode_option PROTO((int, char **)); in gcc/p/lang.c: #ifdef EGCS int lang_decode_option (argc, argv) int argc; char **argv; { return pascal_decode_option (argc, argv); } #else /* not EGCS */ int lang_decode_option (p) char *p; { return pascal_decode_option (p); } #endif /* not EGCS */ However, I am not using EGCS but gcc 2.95.3. Is comething configured incorrectly? Theo Carr-Brion

Borland Pascal emulation : mayday, mayday, mayday !
by Jean-Pierre.Chevillard 03 Sep '01

bonjour, my question is : " is it, in GPC, some replacement for Borlnd's {R+ } ( = range check at run time, mainly on arrays indices) ?" I did not find any trace in the GPC manual. My trial (see below) where unsuccessful and I need it for my students ... with thanks, sincerly yours, J.-P.
