Thanks for the hint. I played around with my manual compile command,
and found that I can duplicate the crashing behavior of the gmake
build if I do *either* of the following two things:
1) Omit "-fobjc-exceptions" from the command I gave above:
g++41 -I$GNUSTEP_SYSTEM_ROOT/Library/Headers
-L$GNUSTEP_SYSTEM_ROOT/Library/Libraries -lobjc -lgnustep-base -o main
main.m
(same result if I use gcc instead of g++).
2) Split the linking into a separate step, *and* use gcc instead of g++:
gcc41 -c -fobjc-exceptions -I$GNUSTEP_SYSTEM_ROOT/Library/Headers -o
main.o main.m
gcc41 -L$GNUSTEP_SYSTEM_ROOT/Library/Libraries -lobjc -lgnustep-base
-o main main.o
(it doesn't crash if I use g++ instead of gcc, though). In both cases
(1) and (2), I get "Abort trap: 6 (core dumped)" when I run the
program, as with the gmake build. For reference, I've attached the
output of "gmake messages=yes", which does basically the same as (2)
above.
The fact that g++ works while gcc doesn't makes me think there's some
library that's not getting linked somewhere, but wouldn't the linker
yell at me in that case?

will display exactly the command-line commands used to compile and link; you
may
want to try it out and compare those with the ones you use yourself ... that

provide some light on what the problem could be. :-)
Thanks

Subject: Crash with new-style exceptions on FreeBSD amd64
I'm having problems using "new-style" exceptions with GNUstep on
FreeBSD 6.2 (amd64). I have the following program (main.m):
#include <Foundation/Foundation.h>
int main(int argc, char ** argv) {
@try {
@throw nil;
} @catch (id thing) {
printf("caught!\n");
}
}
which runs file when I compile it with:
g++41 -fobjc-exceptions -I$GNUSTEP_SYSTEM_ROOT/Library/Headers
-L$GNUSTEP_SYSTEM_ROOT/Library/Libraries -lobjc -lgnustep-base -o main
main.m
but crashes with an "Abort trap: 6 (core dumped)" when I compile it
using gmake. I tried to run it under GDB, but all I get is this:
warning: Unable to get location for thread creation breakpoint: generic
error
[New LWP 100171]
Program terminated with signal SIGABRT, Aborted.
The program no longer exists.
I'm running the following versions of the GNUstep libraries (compiled
from ports):
gnustep-back-0.11.0
gnustep-base-1.13.1
gnustep-gui-0.11.0
gnustep-make-1.13.0_4
Any ideas or suggestions?
-Michael
