RE: 64-bit debug on Solaris

[Hillel (Sabba) Markowitz]

It turns out that a test program compiled on Solaris 8 will debug successfully 
even when run on a Solaris 7 platform.  A test program compiled on Solaris 7 
(in 64-bit mode) will fail even when executed on a Solaris 8 platform.  The 
gdb result (also built in 64 bit mode on the correct platform - Solaris 7 or 
Solaris 8) is as follows

gdb testit
break testit.c:43

Breakpoint 1 at 0x938: file testit.c, line 43

run

Starting program: testit
Warning:
Cannot insert breakpoint 1.
Error accessing memory address 0x938: I/O error.
The same program may be running in another process.

That's really strange.
Normally you can compile a programm on an older system e.g. solaris
2.5.1 and run it without any problems on solaris 2.8. The other way
doesn't work often but in this special case I haven't testet it.

64-bit debug on Solaris

[Hillel (Sabba) Markowitz]

I am attempting to debug a program compiled in 64 bit mode using gcc on 
Solaris 7 or Solaris 8.  Any sample program can be used such as a "hellow 
world".

gcc -m64 -g testit.c -o testit

gdb testit

break "testit.c":43
run
procfs:4235 -- process not stopped
procfs: ...giving up

The same program compiled in 32 bit mode debugs properly.

Has gdb itself been built in 64-bit mode?  As I recall, this is necessary
in order to debug 64-bit programs.

gdb built in 64-bit mode on Solaris 8 works correctly.  On Solaris 7,
the set breakpoint fails.  That is "break testit:43" (for example)
claims to have worked.  However, a "run" will fail when attempted to
actually insert the breakpoint.
