Hello ajblane,

...

I hope you don't mind that I take this to our mailing list

https://lists.sourceforge.net/lists/listinfo/genode-main

The list is the primary discussion forum for Genode related questions. For further questions, other developers have the chance to offer a helping hand. So, please subscribe using the link above.

Regarding your current issue: Do you use a 64-bit Linux installation? Currently, our GDB port is limited to 32-bit and supported platforms are

me@...246...:genode.git> (cd ports/lib/mk; find -name "gdbserver_platform.mk ") ./foc_arm/gdbserver_platform.mk ./pistachio_x86/gdbserver_platform.mk ./foc_x86_32/gdbserver_platform.mk ./linux_x86_32/gdbserver_platform.mk ./fiasco_x86/gdbserver_platform.mk ./okl4_x86/gdbserver_platform.mk ./nova_x86_32/gdbserver_platform.mk

Dear sir: I want to use Qemu's GDB stub to debug, so I read these articles

which

...

are "How to start exploring Genode" and "User- level debugging on Genode via GDB".

I do six steps as follow, but the six step can't work.

step 1: cd <genode-dir>

./tool/create_builddir linux_x86 BUILD_DIR=build.lx

step 2:

cd build.lx make run/demo

step 3: Change to the ports repository and issue the following command make prepare PKG=gdb

step 4: Change to the libports repository and issue the following command make prepare

step 5: Change to the qt4 repository and issue the following command make prepare

step 6: Change to the build directory and issue the following command make app/gdb_monitor

But step 6 can't work. it's error message is

checking library dependencies... Library-description file gdbserver_platform.mk is missing

My question is how to let step 6 can work. Please help me. Thanks.

Best regard.

after re-reading your initial mail, I'm not sure if linux_x86_64 support for GDB monitor is actually what you need. Do you have a specific application that you want to debug? If yes, on which Genode base platform does it run? For the beginning, it might be easiest to try 'make run/gdb_monitor_interactive' on the 'foc_x86_32' platform, since this platform has the best GDB support right now.
