init.c: No such file or directory.

[Benjamin P Myers]

I'm using Absoft's ProFortran f77 compiler on SuSE.  I was able to use gdb on 
SuSE-7.2 prior to my reinstall of SuSE-8.1, but now I get this error:

> f77 -g hello.f
<snip>
> gdb ./a.out
GNU gdb 5.2.1 <snip>
This GDB was configured as "i586-suse-linux"...
(gdb) list
1       init.c: No such file or directory.
        in init.c
(gdb)

According to the docs, Absoft's f77 writes out in 'dwarf' format, so I tried a 
'hello world' with gcc:

> gcc -gdwarf hello.c
> gdb ./a.out  <snip>
(gdb) list
1       init.c: No such file or directory.
        in init.c
(gdb)

So I download and build gdb-5.3:

> cp gdb-5.3/gdb/gdb ~/bin
> gcc -gdwarf hello.c
> ~/bin/gdb ./a.out
GNU gdb 5.3
<snip>
This GDB was configured as "i686-pc-linux-gnu"...
(gdb) list
1       init.c: No such file or directory.
        in init.c
(gdb)

> gcc --version
gcc (GCC) 3.2

> ld -v
GNU ld version 2.12.90.0.15 20020717 (SuSE)

> ls /lib/ld-*.so
/lib/ld-2.2.5.so

I have also tried gcc-2.95.3 with the same result.  The gdb mailing list 
archives suggest that gdb can't find the source file and that I do a 'dir .' 
in gdb before i 'list', but i got the same error.

Anyone have any suggestions?

Thanks for your help.

Is it a problem?  Can you list your program's entry point and set
breakpoints?

That suggests that the init.c is coming from gcc/glibc, and has debug
information.  It's not associated with your application.

It is a problem more for the other people I work with than I, because they 
debug quite a bit more fortran code (and like to use ddd, which this seems to 
break).

I think this is what you mean, right?

> gcc -gdwarf hello.c
> ~/bin/gdb ./a.out
GNU gdb 5.3
<snip>
(gdb) list hello.c:main
No source file named hello.c.
(gdb) break hello.c:6
No source file named hello.c.
(gdb)

vs.

> gcc -g hello.c
> ~/bin/gdb ./a.out
<snip>
(gdb) list hello.c:main
1       #include <stdio.h>
2
3       int
4       main ()
5       {
6         printf("Hello, World\n");
7       }
(gdb) break hello.c:6
Breakpoint 1 at 0x804834c: file hello.c, line 6.
(gdb)

Not much luck.  /lib/libc.so.6 is not stripped.  Are you suggesting I do so?

Thanks for your help.

Then I don't know what's wrong.  MUST you use DWARF?  Is DWARF-2 an
option?

I seem to be saying this a lot lately.

Heh, I installed the glibc source:

15:38:06 dative@padmanabha:~ 0 > gcc -gdwarf hello.c
15:38:18 dative@padmanabha:~ 0 > ~/bin/gdb ./a.out

Unfortunately it does look like I do have to use DWARF.  I tried a few other 
options and none of them would work with the Absoft compiler, and nothing in 
the docs that say anything other than 'dwarf'.  So.  Heh.  I dunno.

Thanks for your help.
