Project
You are supposed to work in groups of two to four people (we recommend four). On the page need partner there is a list of students looking for group members. E-mail sven.robertz@cs.lth.se if you have trouble finding a group partner, and you will be added to the list of students looking for project group members.
I also answer questions about the project, and I will publish questions of general interest here (and the answers).
The report is due Tuesday, April 21 Monday, April 27 2020.

Notes, corrections and comments
Problems building libraries on MacOS
On some versions of the XCode tools, building the library libclientserver.a with the commands used in the Makefile does not work. Creating the archive with the commands:
ar rv libclientserver.a connection.o server.o
ranlib libclientserver.a
will create an archive file that, when used, gives a linker error like
ld: warning: ignoring file /libclientserver.a, file was built for archive which is not the architecture being linked (x86_64): /libclientserver.a
and a list of undefined symbols.
The fix is to use the tool libtool instead or ar and ranlib:
libtool -static -o libclientserver.a connection.o server.o
