Problems using gdb with gcc 4.0.0 in HP/UX 10.20

[Alan Sengillo_1]

I downloaded gcc 4.0.0 for HP/UX 10.20 from http://mirrors.develooper.com/hpux/. When I compile my program with the -g option, gdb does not see any source code.

Gdb works without any problems with gcc 3.4.3. I have made sure I was using the gdb that came with the 4.0.0 install.

Cannot tell from here what's happening. Just tried from the machine that built was made on:

d3:/tmp 110 > cat test.c
int main (int argc, char *argv[])
{
int i = 0;

i = i + 1;
return (i);
} /* main */
d3:/tmp 111 > gcc --version

Here is what happens when I do the same thing. As you can see I am missing line numbers at the break points.

[mouse] 25 % cat test.c
int main (int argc, char *argv[])
{
int i = 0;

i = i + 1;
return (i);
} /* main */

[H.Merijn Brand (procura · Accepted solution]

again, consider an upgrade.

I don't know if you have to blame gcc: 4.1.1 might include more/better debug info than 4.0.0) or gdb (6.3 shows more than 6.2.1).

I was not able to build gdb-6.4 (yet)

The upgrade to 4.1.1 worked.
