gdb changes the path

gdb changes the path

[Pawel K]

Hello
Why gdb changes path while it works ?
My small project consists of 2 files:
/project/main.cpp
/project/include/functions.h 

main.cpp includes functions.h

main.cpp has been compiled as follows:
g++ -O0 -g ...

Now is the case:

(gdb) bre functions.h:100
Breakpoint ... file /projekt/include/functions.h:100

(gdb) bre main.cpp:200
Breakpoint ... file main.cpp

(gdb) bre functions.h:100
Breakpoint ... file include/functions.h:100

1. Why gdb changes the internal path after setting up
the breakpoint at main.cpp ?

2. How to force gdb to use the relative path as in
breakpoint nr 3 above ?

I use:
gdb 6.6
g++ 4.1.2

Thank You for help

Why?  It's a different name for the same file, and GDB knows its full
name.

Since when I specify the breakpoint like:
(gdb) bre functions.h:100

I cannot "list" the source lines.
I can "list" the source line when I specify the
breakpoint like in step 3 or like as follows:
(gdb) bre include/functions.h:100

I also found that when I specify the breakpoint like
in step 3 or like
(gdb) include/functions.h:100

the gdb breaks execution in the next function.
Both functions are defined inside the the same class.

So now I have 2 problems:
1. I cannot list the source code in case of absolute
path.
2. Gdb stops execution in the next function.

As I wrote in my previous e-mail. I compile it as
follows:
g++ -O0 -g ...

Do You have any idea what can be wrong ?

thank You for help

You may want to try a GDB 6.7 snapshot.  I hope this has been
improved.

No, sorry.
