GDB

Is ther any propblem when compiling Pro C programs using the -g flag?

When i run gdb it allways gives me (no debugging symbols found).

I tried with a simple c program and it is alright but with the Pro C makefile it doesn't work. I've done some research but i could'nt find anything.

Can anyone help??

My Hp Ux version is HP-UX 11i v1
and my Gdb version is 5.4.0

I know nothing, but ...

How did you specify "the -g flag" when
"compiling Pro C programs"?

And what's in "the Pro C makefile"?

Assuming that this is actually Oracle Pro*C,
I'm told that "Your system-specific Oracle
documentation has instructions on how to link
a Pro*C/C++ application." Have you looked?

What's your compiler version? It seems you must be using gcc, since gdb 5.4.0 isn't HP's wdb?

In general it is recommended to use latest WDB version (i.e. WDB 6.0). However WDB does not support Pro C.

Thank you for the reply, wdb could be an option by i can only access the server through telnet, and i can't open a display to use it.

I'm using cc to compile the program and i added the -g option to every compile lines in the makefile.

env_pre.mk

GFLAG = -g +d
CFLAGS = -c -I$(REFHEA) -I$(USRXIT) -D_HPUX_SOURCE +DAportable -Ae
CFLAGS1 = -c -I$(REFHEA) -I$(USRXIT) -D_HPUX_SOURCE +DAportable -Ae

makefile

$(CC) $(GFLAG) $(CFLAGS1) $(EXEC).c -o $@

the files have more code, but i would rather not to post here both code.

I think i have tryied everything, and i've seen posts with people saying that it works.

If you need more information i'll send it.

Thank you.

WDB comes with wdb and HP's gdb, use the latter.

>I added the -g option to every compile lines

Did you also add it to the link line?

$(CC) $(GFLAG) $(LDFLAGS) $^ $(OBJS) $(PROLDLIBS) -lcurses

This is the link line, correct?? I added the -g option to this line and it didn't work.

I didn't made the makefile, it was already made, but there was no debugging option, wich can be a pain...

It's strange because i made a simple c program to test, and it worked, it must have something to do with my makefile correct...

include env_pre.mk

MKFLIBS=$(URLIB) $(USERLIB)

IAP_MK=$(EXEC).o
#$(IAPOUT)/$(EXEC): $(IAP_MK) $(MKFLIBS)
$(EXEC): $(IAP_MK) $(MKFLIBS)

Yes.

>strip $@

Ack! Comment this, it strips the debug info!

It worked... :)

Pro*c developing will become much easier.

Thank you so much for your attention...
You are the best.
