Many users are actually the "systems guy" in a group. They are responsible for providing the properly built BSP and tools in the group. This could be on a single server, a VM which is copied or pre-built tools.

Assuming you mean the x86_64 bit port and accompanying BSP. If you noticed my post yesterday, we have tripped across a new embedded PC without legacy PCI BIOS support.

Or even at the configure.in/ac script in its source. It is looking for a very specific file to link against and failing. yum have a "provides" subcommand to search for which package provides a specific file. Apt must have a similar capability. So you can figure out the file gdb needs to link and the corresponding package which includes it. --joel > ___ > devel mailing list > devel@rtems.org > http://lists.rtems.org/mailman/listinfo/devel > ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel

I am facing the same problem one developer faced mentioned here in feedback. https://devel.rtems.org/wiki/GCI/Coding/HelloWorld for ubuntu 15.10 . I have to try ubuntu because I don't know exactly where I can force build-rep to build with python2.7-dev instead of python2.7 .For cent os someone already solved the problem here https://devel.rtems.org/ticket/2275.
