The module linux.py is also broken. The error is the lack of the dist module that effected master recently.

I am wondering if I should back port all the python code from master? It is clean and working on all hosts and is stable.

GDB 7.9 does not build because that version of GDB only supports python2. I suggest we move to the same version of Python as master (9.1). The GDB version does not effect the target code.

RTEMS tools is also suffering from the same problem in macros.py with python 3.8.2.

Updating gdb to 9.1 breaks 4.11/rtems-sparc because the SIS patches do not apply. I cannot see an easy way out of this because we are wedged between no Python2 support and the need to support packages for a long period. The sparc will stay with gdb 7.9 and I will disable python.

Assuming it works as I expect, backporting RSB code from the master is fine to address this. All release branch dependencies should be in configuration files.

Resolution: fixed
Status: newclosed

In 158ad68/rtems-source-builder:

sb: Back port the RTEMS 5 and 6 RSB engine.

  • Build GDb first as we do for RTEMS 5 and later
  • Update GDB to 9.1 for all archs expect SPARC. The SIS patches only apply to 7.9. Disable Python for SPARC
