You can find a corrected file at: ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/beta/gcc-2.8.1.diff.gz After putting it in place, be sure to start with fresh GCC sources -- otherwise GPC will think GCC is alredy patched and not apply the correct patch.

running slakware 3.5 on an i486. Liked gpc 2.0 so downloaded gpc-199808* put gpc-2.8.1 in /usr/local/src and unpacked gpc.

Code Generation Problem, btw...
by Orlando Llanes 21 Sep '98

21 Sep '98

Now that I think about it, the problem I'm having might be a linking problem rather than a code generation problem (or maybe it's a combination of both?) See ya!

Alright, as you may suppose, we can't find the problem with this description alone. So perhaps you can mail the sources to me privately, not to the list if they're big (please with an exact description how to compile them and how to run the program to reproduce the error)... -- Frank Heckenbach, frank(a)fjf.gnu.de http://fjf.gnu.de/ PGP and GPG keys: http://fjf.gnu.de/plan

Code generator problem?...
by Orlando Llanes 18 Sep '98

I recompiled a program to test my libs, and my program crashed. I suspect that it's the importing of externals because I recompiled Bernie's BWGraph libs and they also crashed (both his sources and my sources did not crash with the previous version of GPC). The reason I suspect importing of externals is because I printed a value that should have been filled by an externally declared program, it seems as if none of the routines declared outside are working properly. I'll have to warn you if you need the code, I don't know if there's anyway to reduce it to reproduce the error. BTW, I'm using the DOS version of GPC. See ya!

Yes, indeed the gcc-2.8.1.diff supplied with the last source release was incomplete.

Hi, [please respond by direct mail as well as I'm only just in the process of joining the list] I cannot build gpc-19980830 with gcc-2.8.1. It seems that the patch in p/diffs/gcc-2.8.1.diff is incomplete in regard to the 'toplev.c' file. It only changes some empty lines, where it seems that it should make the variable 'version_flag' available as en external symbol, as this is what the file 'gbe.h' assumes to be the case: /* toplev.c */ extern char *progname; extern int version_flag; extern void pedwarn PVPROTO ((char *, ...)); extern void warning PVPROTO ((char *, ...)); extern void error PVPROTO ((char *, ...)); extern void fatal PVPROTO ((char *, ...)); extern void error_with_decl PVPROTO((tree, char *, ...)); extern void rest_of_decl_compilation PROTO ((tree, char *, int, int)); extern void warning_with_file_and_line PVPROTO ((char *, int, char *, ...)); The result is a linking problem. gcc -DIN_GCC -DGPC -DSVR4 -g -o ../gpc1 \ `cat stamp-gbe` ../c-aux-info.o ../c-iterate.o ../c-pragma.o ../choose-temp.o ../pexecute.o mkstemp.o gpc-common.o gpc-convert.o gpc-decl.o gpc-lang.o gpc-lex.o gpc-typeck.o module.o gpi-hash.o circle-buf.o objects.o parse.o rts.o types.o util.o setop.o version.o `if [ xobstack.o != x ]; then echo ../obstack.o; else true; fi` `case "gcc" in "cc") if [ xalloca.o != x ]; then echo ../alloca.o; else true; fi ;; esac` `if [ x != x ]; then echo ../; else true; fi` Undefined first referenced symbol in file version_flag module.o ld: fatal: Symbol referencing errors.

time bug
by Maurice Lombardi 08 Sep '98

08 Sep '98

Hi all I have finally found the answer to a very old DOS bug 34396148.5C71(a)ujf-grenoble.fr namely a bug appearing when running time.exe from command.com, and not when running it within rhide or under the bash shell. This has nothing to do with gpc, but it is due to a bizarre characteristic of DOS. When there is no explicit directory in a command, the name is looked for in the set of "internal commands", the current directory and in the paths listed is the PATH variable, in that order. And time is an "internal command" in DOS. So when you type "time.exe" DOS understands the command "time" with a parameter (which should be the new time) .exe (or exe with . as a separator), which makes no sense, and it barks invalid time. The workaround is to type explicitly the directory .\time.exe, so that there is no search for implicit directories. This is a common practice in unix shells, because the current directory is not prepended to the path list, but is usually never done in DOS. So remove the bug from the bug list and forget it. Or may be change the name time.p in the test list to tim.p (an change accordingly the makefile) to avoid the bug popping anew for an other user.
