I have installed libbsd package (made
RTEMS_POSIX_API=True,RTEMS_NETWORKING=True in config.ini file to
enable POSIX and networking) but I am still confused about the work
already done in this project in past. Also after interacting on
discord I think completely replacing  mongoose with another web-server
is not a good option since it may rise some user complaints who are
already using old system and may find it difficult to instantly switch
over to new system , instead civetweb can be added as an extra new
web-server where user has a choice to either use old mongoose or the
new web server both having all dependencies and functionalities
available.

Also I still don't know whether the project #4334 is long enough for
summer of code project and after going through docs I think
https://devel.rtems.org/ticket/4272 is also a very interesting project
since now I think I know a little bit about BSPs and I am good in
python and know shell-scripting. I would be very grateful to know more
about this project.
Thanks.
