The m/c I use is Solaris running:
SunOS hirst 5.10 Generic_118822-26 sun4u sparc SUNW,Sun-Blade-2500
I have gcc version 3.4.3 installed:
Reading specs from /usr/sfw/lib/gcc/sparc-sun-solaris2.10/3.4.3/specs
Configured with:

I have two problems when I enter GDB debugger via DDD (I get the problem even
without DDD) I get the following:
1) (gdb) run deptsv li ~/lsa/src/web/inp.file
warning: Lowest section in /usr/lib/libthread.so.1 is .dynamic at 00000074
warning: Lowest section in /usr/lib/libdl.so.1 is .dynamic at 00000094
Breakpoint 1, w_listDepts () at /export/home/lisa100/lsa/src/web/web_depts.c:63
/export/home/lisa100/lsa/src/web/web_depts.c:63:1519:beg:0x12064
Why am I getting the 'Lowest section...' message ? How can I avoid it ?
2) When I step through line by line through the code using 'n' for next, when
it hits a particular while loop I get the following:
(gdb) n
Single stepping until exit from function w_dept_populate,
which has no line number information.
w_listDepts () at /export/home/lisa100/lsa/src/web/web_depts.c:73
I have built all the C modules with -g flag and I get this with both versions
of gcc. I cannot seem to step through the code in my while loop. Please help. I
need to know what I am doing wrong or what is causing this. As the module has
been compiled with -g I would have expected every line to be stepped through.
Please note that I can set breaks to one of the lines in the while loop buut
the moment I say 'n' I get the above message.....
Please help...
Cheers,
Alex
