    Hi,

    Excuse again if my questions if these are obvious. I’m evaluating the product and there is a very steep learning curve for me, I have managed to resolve a number of issues but I have been really stuck for a few days with this one issue and the Eval license will finish in about a week.

    End goal:

    I’m hoping that I can learn about technology from an existing open source project, with the goal of debugging this code remotely, understand how it works and potentially improving it. This code has been designed to run on Raspberry Pi and it uses other hardware like the Pi’s camera.

     

    Problem:
    I have setup a Linux project by using the import wizard, I have eventually managed to solve some issues by adding folders into the Intellisense directories, the debugger is now running as root with sudo, and the exception handling has been modified to ignore SIGILL for visual studio and for VisualDGB.

    The current issue I have is that the when I debug the code, I can only step through assembly, I’m hoping that I can step through the code.

    In the GDB session window, I see the following message “No symbol table is loaded.  Use the “file” command.”

    Any suggestions would be greatly appreciated.

    Hi,

    First of all, if your evaluation license runs out before you get things to work, please contact our sales and they will give you a trial extension.

    Regarding the “no symbol table” error, most likely your program was built without the “-ggdb” argument and hence does not contain information required to map the disassembly back to the source code. If you are using VisualGDB Project Wizard to generate a project, it should setup everything automatically, but if you are importing a 3rd-party project, you may need to adjust its build files.

    If the project is built with GNU Make, please search the Makefiles in different directories for lines defining CFLAGS (you can search for -O1, -O2 and -O3 options that define the optimization level). Once you locate them, please add -ggdb to the list of CFLAGS and rebuild the project. If this does not help, please enable verbose build logging and double-check that the -ggdb argument actually gets passed to gcc.

    If you are not sure, feel free to post further details here and we will point you to the right direction.

    Thank you, I managed to add that flag and the debugger progresses a bit further, but it goes into the assembly after a couple of lines again, this time the logs come up with the following message.

    No symbol \”disassembly\” in current context.”

    If you could point me to a direction on how to enable “verbose build logging” would also be appreciated.

    It might be important to mention that there are external components/header files like CURL, that are are refereed to by the project but are outside the project folder.

    Regards,

    The log file that it generated can be accessed here, thanks in advance again.

    Hi,

    Thanks for the log file. It looks like after you run the ‘step over’ command, the main() function exits and the next stop is in the library code:

    Please try disabling optimization for your project to make stepping more transparent. This can also be a gdb bug related to stepping. In that case setting breakpoints and pressing F5 instead of stepping over the lines may help.

    Regarding the verbose build logging, this depends on the internal structure of your project. Typically it is enabled by adding V=1, _V=1 or VERBOSE=1 to Make arguments, but it may be different in your case.
