Question

Hi,
I have installed Solaris studio and wanted to use the memory analyzer from there. I am trying it on a sample program, but it returns the above error and does not instrument the executable. Could you please help me tracing where am I going wrong.
# which cc
/opt/SolarisStudio12.3-solaris-sparc-bin/solarisstudio12.3/bin/cc
# /opt/SolarisStudio12.3-solaris-sparc-bin/solarisstudio12.3/bin/cc -V
cc: Sun C 5.12 SunOS_sparc 2011/11/16
# cc -g -O2 test.c
# file a.out
a.out:          ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required, dynamically linked, not stripped

ok. Thanks for the info.
Could you check if a small test works on your system ?
You could use this test :
% cat a.c
#include <stdio.h>
#include <stdlib.h>
int main()
        int *x = (int*)malloc(100);
        printf("x[0]=%d\n", x[0]);
        return 0;
% cc a.c -g -xannotate
% discover -w - -o a.out.disc a.out
% ./a.out.disc

                7:
                8:      printf("x[0]=%d\n", x[0]);
                9:
        _start() + 0x71
x[0]=0
