The UrJTAG uses a libtool wrapper for starting, so debugging with GDB is a bit tricky.

You should debug the src/apps/jtag/.libs/lt-jtag binary.
But it does not appears right after building it, the wrapper script creates it if not exists.
So ran ./src/apps/jtag/jtag first.

Figuring out taken me some time, I hope it will helps someone.

So execute

gdb ./src/apps/jtag/.libs/lt-jtag

in the trunk and enjoy debugging .

Recently I had a project which was based on a 18F series PIC.
According to the "The well known ecosystem improves the productivity" motto I have decided to do the development on my Linux box.

After a while I have noticed that there are not any usable enviroment for 18F development on Linux. I have tried the MPLAB on windows too, but the "ignore all well known gui actions (doubleclick on code makes breakpoint for e.g.)" idiot behaviour driven me crazy. The Piklab is an unstable stuff, the MPLAB X is a java based slow bullshit, which does not supports ICD2, Piklab2.

I have decided to setup an enviroment using GNU make. The Makefile below can be used with the Linux version of MCC18 compiler.

Preface: I will call new bus "foo" in this example, so replace the foo with your bus name in the examples case sensitive.

1. Write the bus code. (Implement the necessary functions, and members for the URJ_BUS_DRIVER structure. see. include/urjtag/bus_driver.h)

2. Add the bus to the URJ_DRIVER_SET([bus], []) array in the urjtag/configure.ac

3. Add the following code the urjtag/src/bus/buses_list.h:

#ifdef ENABLE_BUS_FOO
_URJ_BUS(foo)
#endif

Please keep this list sorted alphabetically as it noted in the header.

4. Add the following snipplet to the urjtag/src/bus/Makefile.am:

if ENABLE_BUS_FOO
libbus_la_SOURCES += foo.c
endif

5. Now you are ready to make the UrJTAG with the new bus. Run ./autogen.sh && make in the source directory.

Or anything else what is modifying somehow the output of the GCC.
Otherwise you will suck like a gluttonous badger* like I did.

A.k.a torkos borz in hungarian.
