Why can't I use gdb?

[Linda]

After I type "make" on the screen, I got the following result:

/usr/local/sunone/SUNWspro/bin/CC -xs -pto -PIC -xtarget=ultra
-xarch=v9 -DIL_STD -g -xs -DNDEBUG
-I/usr/local/ilog/solver60/include
-I/usr/local/ilog/solver60/../concert20/include
-I/usr/local/ilog/solver60/examples/include
/uac/rshr/xhji/Ilog/money.cpp -c
/usr/local/sunone/SUNWspro/bin/CC -xs -pto -PIC -xtarget=ultra
-xarch=v9 -DIL_STD -g -xs -DNDEBUG
-I/usr/local/ilog/solver60/include
-I/usr/local/ilog/solver60/../concert20/include
-I/usr/local/ilog/solver60/examples/include money.o -o money -g
-L/usr/local/ilog/solver60/lib/ultrasparc64_8_ 6.2/static_pic_mt
-L/usr/local/ilog/solver60/../concert20/lib/ultrasparc64_8_ 6.2/static_pic_m*t

-lsolverfloat -lsolver -lconcert -lsocket -lnsl -lm -lsunmath
We can see that "-g" is there. But when I type "gdb money"(money is my
executable file name:)), I get:

So I cannot debug normally! Then what's wrong with it? How can I debug
with gdb or dbx normally?
Thanks!

Please try 'gnu.utils.help ' or any other '.help' newsgroup from the
'gnu.*' hierarchy. Here any utilities are OT since they are platform-
specific. As the last resort you should try a newsgroup for your OS.

Have you tried dbx as a debugger for this binary?
As the compiler you've used is Solaris CC, it is advisable to try dbx.

Thanks! And I have tried! When I type "dbx money", the result is:

Reading money
Reading ld.so.1
Reading libsocket.so.1
Reading libnsl.so.1
Reading libm.so.1
Reading libsunmath.so.1
Reading libCstd.so.1
Reading libCrun.so.1
Reading libw.so.1
Reading libc.so.1
Reading libdl.so.1
Reading libmp.so.2
Reading libc_psr.so.1
dbx: warning: Skipping debugging info (incompatible format) in
'money.o'

And in dbx, when I type "stop at 41", the result is:

dbx: no executable code at line "money.cpp" :41

So, what I should do next? Thanks!

I think you would have displaced your binary/source file to someother
place.
I mean, if the binary is moved to someother place from the original
place where compiled, after successful compilation with -g option, then
the debugger attempting to look at the source at the original location
fails which could result in not showing the source lines in debugger.

Please check that.

I cannot fully understand your suggestion. But after I removed those
things like -w -xO4 -xtarget=ultra -xarch=v8plus in Makefile, dbx can
work normally. But gdb can not still.

Thank you anyway!

As Victor told you, this off-topic here. You will better and more
thorough answers in the correct newsgroup. Also, read the information
below.
