Hi there,
I'm trying to build RTEMS to see about starting development work, I took
the advice to build the tools as per the user manual, and everything goes
okay until this page:
https://docs.rtems.org/branches/master/user/start/tools.html
I've followed the instructions but when I try and actually build the tools
(i.e. ../source-builder/sb-set-builder --prefix=${RTEMS_PREFIX?}
5/rtems-sparc) I get a linker error with lots of undefined references to
tputs, e.g.:
~~~
gcc -O2 -pipe -I/home/john/src/
git.rtems.org/rsb/rtems/build/tmp/sb-john/5/rtems-sparc/home/john/src/git.rtems.org/install/include

undefined reference to `tputs'
~~~
I'm not sure how to go about solving this in the context of the RTEMS build
system. This thread (https://github.com/monero-project/monero/issues/2919)
seems to suggest I just need to link in termcap wherever readline is,
though I can't find where that's done.
I'm coming back to this sort of development after a long break, so may have
missed something obvious! I'm using a fresh Ubuntu 19.04 system, nothing
installed except emacs and what the RTEMS user guide says.
Thanks for any help,
John
