It is sufficient to test only with sysmoBTS.

You need to build only openbsc.git's osmo-nitb from source in order to test the patches.
The other software components can be as you like.

Before you build openbsc, apply the patches like this:

cd openbsc
git fetch https://gerrit.osmocom.org/openbsc refs/changes/84/1684/4 && git checkout FETCH_HEAD

(checking out 1684 is correct and fetches all patches, because all of the others including 1685 are parents of 1684)

To check that your source tree has the right patches, the output of

git log --oneline

f311e18 add struct gprs_sub, separating gprs from gsm_subscriber
a9a122b SGSN: Integrate basic support for UMTS AKA
50c7022 add struct bsc_sub, separating libbsc from gsm_subscriber
f06d521 log: disable imsi filter
2ca7d8e Introduce subscriber_connection ref-counting
63c9a54 gsm0408_rcv_cc: guard against NULL subscriber
b3d2ad9 abis_om2000: drop unused function con_group_del()
5bd5170 paging.h: use '<>' include, not '""'
7d209ee osmo_bsc_grace.h: use '<>' include, not '""'
32b5dfc various comment / whitespace tweaks (libmsc, gprs, libcommon-cs)
f6e5170 CTRL: remove boilerplate
[...]

Then make clean and make install in the openbsc source tree.
Make sure that these ran successfully.

Perform tests with this osmo-nitb that was just built.

To get your openbsc.git source tree back to what it was, you can

git checkout master

Thanks!

and ... before you start, make sure that https://gerrit.osmocom.org/1684 has been verified with a V+1 vote by jenkins,
otherwise the build will probably fail for you as well; rather wait another day in case it has V-1.

results:

During the test it was seen, that CS call can not be established. SMS test also failed. GPRS - successful.

In our chat I had asked for TCH/F config, specifically not dynamic timeslots, but ok, I'll make do with this then.

The patches have been tested and fixed or abandoned.
