Hello,
I tried compiling RTEMS-libBSD with RTEMS6 toolchain and the new build
system
but failed. I get errors when compiling RTEMS-libBSD
The new build system is pulled from Sebastian's branch
HEAD: e4c193ddc163d6adb1b003254af9cc6b5d174a6f
RTEMS was configured with the following options:
1) ./waf bsp_defaults --rtems-bsps=arm/beagleboneblack > config.ini
2) Enabled posix since libBSD complained about it during configuration.
3) ./waf configure --prefix=$HOME/development/rtems/6
4) ./waf -j32
This didn't work for me. I got:

This error is related to this change:
https://git.rtems.org/sebh/rtems.git/commit/?h=build&id=9e3a23e4dde96fca2fc5855995527e10a4a119cb
I guess I made this during the work to get rid of the bsp_specs. The
problem is that we have a cyclic reference: librtemstest depends on
librtemscpu which depends on librtemstest (via the wrapped output
functions). The librtemscpu and librtemsbsp are implicitly given at the
end via the -qrtems flag. I reverted the change since it seems to work
without it. Afterwards, I was able to install the BSP.
5) ./waf install
RTEMS-libBSD was configured with the following options:
1) ./waf configure --prefix=$HOME/development/rtems/6
--rtems-bsps=arm/beagleboneblack --buildset=buildset/minimal.ini
--rtems-version=6
2) ./waf -j16
I have attached the error log file.
I got a different error:

I fixed this with this commit:
https://git.rtems.org/rtems-libbsd/commit/?h=5-freebsd-12&id=26866d2c1f2432b25b5db71995bce2035187c715
Which branch do you use for libbsd?
It seems the master branch. Here I get also your error:
[1084/1184] Linking build/arm-rtems6-beagleboneblack-minimal/condvar01.exe

Could you please use the 5-freebsd-12 branch with the default build set.
This is what I use normally.
