RE: GDB on Solaris 10

Thanks, Joel, on the strength of that I tried it again.

I got GDB 6.8 working for 32-bits just by fixing the warning mentioned
in problem report 2481. The issue described there, I now think is due to
trying to debug a 64-bit application with a 32-bit GDB. (That is what I
was doing and I saw the same errors). This is explained here:

Building GDB for 64-bit was the problem. By googling I found out to try

> CC="gcc -m64" ./configure

Is that the recommended method? I can't find this in the GDB
There are various sparc64 targets in the Makefiles, so I tried things

> ./configure --target=sparc64-sun-solaris2.10

But this just seems to give it a different label. (Or do I need both?)
Is there a list of valid targets anywhere?

There must be something clever going on behind the scenes because the
link lines for 32-bit and 64-bit (when using CC="gcc -m64") are quite

With 64-bit I got complaints about undefined symbols wattr_on and
wattr_off in the curses library, which is not a problem for the default
32-bit compile.

Some more googling led me to:

> CC="gcc -m64" ./configure --disable-tui
> make

And I have a 64-bit GDB that kind of works! So thanks again for the

For future reference I would be interested to know if this is the right
way to compile 64-bit on Solaris, and (unless I have missed it) perhaps
it needs to be documented somewhere?

Yes - we build GDB 6.8 on Solaris 10 for both 32 and 64 bits.
We don't do anything particular to get it working, though, so
I'm not sure what the problem might be in your case.
