Title: GDB problem
Post by: ennom on June 05, 2010, 07:22:12 pm

Hi there!
First of all - i'm newbie in cb, cygwin and gdb. Just downloaded cb to try out. I wrote a little program to see how it going in cb. I have problem with gdb(or cb? or cygwin? or with all of them? :)) when trying to stop at breakpoint -

Cannot open file: C:\src\cb_test\cb_test\->->\cygdrive\c\src\cb_test\cb_test\main.cpp
At /cygdrive/c/src/cb_test/cb_test/main.cpp:26

any ideas?
gdb is GNU gdb 6.8.0.20080328
cb is 10.05
cygwin is CYGWIN_NT-6.1-WOW64
thank u!

What are those strange characters in the paths?

Here is how gdb output looks like. There are no any whitespaces in my path. I suppose that two rectangles in path are two "right arrow" chars, but i'm lack of appropriate font.

Look: the gdb can't find the source file located by \cygdrive\XXXX

I guess your compiler is cygwin gcc, but your debugger is native gdb. So, they are not compatible.

Yeah, compiler is cygwin gcc, but what do you mean 'native'? The only gdb i have is from cygwin, how then it can be incompatible with the compiler?

btw, thank you all guys.

Do you really have right-arrow chars in your path ?
Try it with no special chars in path, this can always be the cause for such issues.

No, i don't have any arrows in path. Path to program code is c:\src\cb_test\cb_test\main.cpp.  I don't know what this mean('@' is placeholder here for char with code 0x1a -i'm unable to print it here, look to pic at my 2-nd post)

but this is how cb shows problem in gdb.

Looks like the compiler has embedded the paths to the sources in a wrong way.
