Building RTEMS tools using Source Builder fails

[Steen Ulrik Palm]

Hi,

I'm new to building RTEMS. I have previously used pre-built RTEMS from Gaisler.

I'm trying to build the RTEMS tools using the Source Builder for the SPARC architecture (to be replaced by ARM later on) on a Debian 8 platform. I have downloaded the Source Builder using the command:

git clone git://git.rtems.org/rtems-source-builder.git

and have verified my environment using the command:

                ../source-builder/sb-check

I try to build the tools using the command:

                ../source-builder/sb-set-builder --prefix=$HOME/dev/rtems/erc32 4.12/rtems-sparc

Many tools and patches are correctly installed, but installation of gdb fails:

...

Looking in the file rsb-report-sparc-rtems4.12-gdb-8.0.1-x86_64-linux-gnu-1.txt shows that the configure command complains about python2.7:

...
checking for XML_StopParser... yes
checking whether to use python... yes
checking for python... /usr/bin/python
configure: error: python is missing or unusable
checking for python2.7... no
Makefile:9095: recipe for target 'configure-gdb' failed
make[1]: Leaving directory '/home/smile/dev/rtems/rsb/rtems-source-builder/rtems/build/sparc-rtems4.12-gdb-8.0.1-x86_64-linux-gnu-1/build'
make[1]: *** [configure-gdb] Error 1
make: *** [all] Error 2

error: building sparc-rtems4.12-gdb-8.0.1-x86_64-linux-gnu-1

But python2.7 works fine:

                $ python -version
                Python 2.7.9
                $ python2.7 -version
                Python 2.7.9

Two questions:

1.       Is this a known issue?

2.       Is it possible to proceed without having to rebuild already installed tools (like newlib, which takes very long time to build)?

I have also tried to use released versions of the Source Builder (4.11.1 and 4.11.2). When using these versions, the building of newlib fails because gcc cannot find zlib.h included by one of the source files.

Is this a known issue?

As mentioned above, I have never built RTEMS before, so I'm a newbie in this area.

Best regards,
Steen
