Question

I am calling fortran 90 code from a c code. There is a main() (in c) that calls a wrapper function in the same file, that calls a fortran subroutine (actually in a liblibrary.a). I am working on linux. Now, I’m using gdb to debug the executable, but it cannot find the main.c file. I added the working directory using

directory /my/working/directory

but still it says there is no file named main.c
If I type list inside gdb it shows me a piece of fortran code. If I type show language, it says The current source language is auto; currently c.
If I run the executable and then I interrupt it and look to the stack it will show me the c-functions I am calling, but it will not state the source file, that instead will state for the fortran subroutine and function.
I am trying to investigate if I am passing the variables correctly from c to fortran and backwards, I suspect I am not.

The same thing happens in idb, more or less. when I try to put a break in main.c, it says not found. I compiled the fortran code with these flags:

-g -O0 -check bounds -warn all -traceback -align all -align rec8byte

and the c-code with:

-g -O0  -Wall

All suggestions are welcome.

Hello you need additional flag to put debug info into your executable.
Here is manual for intel compiler:

Please try -debug full as on page 35 written.
