Project
The project is to be done in groups of two to four people (we recommend four). You need to form groups yourselves, and to facilitate that there is a discussion "Looking for project group members" in Canvas.
I also answer questions about the project (preferably in Canvas), and I will publish questions of general interest (and the answers) there.
The report is due Wednesday, May 4 2022.

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
UBSan complains on M1 macs
Something in the library functions for getting the IP address for a hostname may cause the undefined behaviour sanitizer to complain about "load of misaligned address" on a Mac with Apple silicon. This can be disregarded.
