Generating 32 bit applications on Solaris 9 / UltraSparc III+

Question

Hallo.
I wish to generate some 32 bit applications on Solaris 9 and UltraSparc III+ platform. I need to do that as my process have to dinamically link a 32 bit shared object previosuly installed by another software (to be precise, the library is an "ELF 32-bit MSB dynamic lib SPARC Version 1, dynamically linked, not stripped").
After my generation, some executables that runned perfectly on my previous UNIX SCO platform, now crash when exiting.
Moreover I find out that my master process correctly launches the execution of a slave process (I traced the values of the paramters passed to the execv() system call) but the slave process immediatly exits because it gets wrong parameters (I found out that in the main() function within the slave program, the argc parameter is 0 (!!) that sounds really really strange!!)
Is there anyone able to help me?
For your information, when I compile my objects I use the following options:
cc -g -xc99=none -xtarget=ultra -xchar -c <source>
and when I link them I use the following:
/usr/ccs/bin/ld -z defs -z verbose -dy -B dynamic -o <processname> <object list> <shared library> -lm -lc
Doing so, both the master and slave process are "ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, UltraSPARC1 Extensions Required, dynamically linked, not stripped"
Thank you in advance!!

Why do you want to make your own link lines?
Use cc to link, not ld. You ask for trouble.
I made the following program:
int main(int argc, char **argv) { return argc;}
% cc -c t.c
Then used your link line to link it:
% /usr/ccs/bin/ld -z defs -z verbose -dy -B dynamic -o a.out t.o -ln -lc
% a.out
Segmentation fault (core dumped)
Use cc to link. Do not try to use ld. Or if you really, really think you have to use ld yourselves, run cc -### ... first to se what link line it uses, and try to make the variation you need yourselves. But all kind of options to ld can also be given to cc.
