Cygwin with CodeBlocks gdb error

(1/5) > >>

venom4u31:
I have Code Blocks 12.11 and I have Cygwin 1.7.27 installed. I have configured C::B to run the Cygwin compiler and it works, but when I try to run the debugger from the Code Blocks environment I get the error:


--- Quote ---Cannot open file /cygdrive/c/some_path/main.c

At /cygdrive/c/some_path/main.c:15
--- End quote ---

If I try to run gdb on the same file from the cygwin command line interface, it works.

Can somebody please help me fix this problem?

oBFusCATed:
Can you post the full log from the debugger? (you should enable it first in settings -> debugger)

venom4u31:
Sure, here it is:

ouch:
I would check your source directories:


--- Code: ---Source directories searched: /cygdrive/c/test_project/C:/test_project:$cdir:$cwd
--- End code ---

because that looks messed up...

ollydbg:
I have no experience with cygwin(gcc+gdb), but for your problem, I think it is good to build your exe with "relative path" enabled, so that C::B or GDB can try to search/open a file with relative path.

To use the relative path, you can try Settings->compilers->other settings->advanced options button->Others

Then, De-select the option "Use full path for source files(GDB workaround)".

BTW: it was a GDB workaround option, but with modern GDB(I think version >7.0) handles source file paths very well. So, it is safe to de-select this option.
