phil@cgrg.ohio-state.EDU (Phil Ritzenthaler) (04/10/91)
Background:
Sun 4/280
Sun OS 4.1.1
GNU gcc compiler version 1.39
Problem:
Unfortunately, I don't read this news group as often as I probably should, but
I cannot get perl 4.0 to compile using gcc. I run through the standard
Configure just changing the line cc to gcc when it asks. Judging by what
occurs after, Larry obviously has made provisions for gcc in the Configure.
From the compilation:
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g perly.c
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g array.c
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g cmd.c
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g cons.c
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g consarg.c
gcc -c -fpcc-struct-return -I/usr/include/sun -O -g doarg.c
doarg.c: In function do_assign:
doarg.c:1067: `environ' undeclared (first use this function)
doarg.c:1067: (Each undeclared identifier is reported only once
doarg.c:1067: for each function it appears in.)
doarg.c: In function do_undef:
doarg.c:1297: `environ' undeclared (first use this function)
*** Error code 1
make: Fatal error: Command failed for target `doarg.o'
========================================================
It compiles fine using cc . . . anyone have a work around for this?
Thanks . . .

don't bother compiling Perl with gcc on a SPARC based machine. it
just is not going to work. the problem is that gcc and Sun's cc pass
structures differently, and the dbm routines take parameters that way.
since the dbm library is compiled using cc, calling those functions
from gcc will cause major league problems. what about using gcc's
-fpcc-struct-return, you may ask? well, that works for structure
*returns* not structure passing. 'tis a pity, though. i really like
gcc. when gcc 2.0 finally comes out, this will be fixed. should
there be a note to this effect in the perl distribution? or is there
one and i missed it?

I compiled the file the calls to the dbm routines are in (whichever one that is) with cc and everything else with gcc (v 1.37.1, I think) and everything worked fine. This was perl 3.0 at patchlevel 40, I think. ^.-.^ Mark Purtill purtill@dimacs.rutgers.edu (908)932-4580 (O) ((")) DIMACS, P.O.

What files have to be compiled with cc to make the dbm stuff work? I hope
not all of them!

You can also get around this by adding -U__STDC__ to the CFLAGS.

Of course some of us think that passing, returning, and assigning structures is A BAD THING and never should have been legalized. Fortunately, only the DBM people were stupid enuf to use it. -- [rbj@uunet 1] stty sane unknown mode: sane

I did as a person from MIT suggested (thanks) and commented out the ifdef's around the environ variables and got perl 4.0 to work with gcc . . . kinda. It fails the test perl/t/op/dbm.t . . . hence the reply to the posting from rbj@uunet.UU.NET. Since these structures are passed, is dbm.t EXPECTED to fail if you use the gcc compiler? They all pass using Sun's cc . . . of course who said Sun's cc was a standard?? Sometimes I'd just like to take another's advice and give up on gcc and perl, but right now I feel this shouldn't be . . . Any takers?? Thanks . . .

Well, I remember in Perl3.0.xx Configure used to have -fpcc-struct-return,
but whether that works on sparcs I don't remember for sure. You could use
gdbm instead n/dbm, that should work.

Have you considered using one of the dbm replacement packages, compiled with gcc? I think at least one of them is compatible with the stock dbm, or comes with a utility to convert old dbm files to new ones. -- Hokey We are Space Guys. We know what we are doing.
