#13 [debugging] no source file named xxx.c

[MarcoSartore]

Hello,
I am using BVRDE version 1.3b to remotely debug c programs on the RaspberryPI. I have created a file which makes use of the library bcm2835-1.36 to access SPI and other pins. I have successfully compiled with the following Makefile:

all: lp

lp: lp.o
gcc lp.o -lbcm2835 -o lp

lp.o : lp.c
gcc -c lp.c

clean:
rm -rf *o lp

When starting the Debugger I had to add "sudo" to the command "gdb" to successfully start it. But suddenly BVRDE reports the error "no source file named xx.c". Please notice that the file was before successfully compiled by BVRDE with "rebuild project", so to some extent the file is seen and recognized.
Please also notice that I have open manually the file xx.c from the project windows as it DOES NOT open automatically as predicted.
Then I adden one single breakpoint at the beginning and hit "Start with Debugger".
This is the Console Output:

Please notice that if I don't use BRVDE the program runs successfully remotely by command line.

Any help is appreciated,

Hi,

From your Makefile I would have expected to see an error during debugger attachment saying "No symbols found", as you don't build with the gcc -g option. Does this help?

Also you could try to execute "dbg info sources" in the BVRDE Command View to see what files GDB can actually see while debugging.

Hi,
many thanks for your quick support.
Adding the -g option which I forgot earlier fixed the issue. Many thanks again,
Marco
