I'm building a static library for a small project, and when I compile it with ar, it correctly links.
When I go to include the relevant header file and link the test script to the archive;
LINK = -lpthread -lcryptopp -L./path/to/archive/ -luttu
r: ../inc/uttu.hpp
g++ -std=c++20 rnet.cpp -o r.out $(LINK)
I get linker errors;
/usr/bin/ld: /tmp/cc7h6RHu.o: in function `main':
rnet.cpp:(.text+0x263): undefined reference to `np::np()'

Running ar t libuttu.a returns
linux.o
uttu.o
timeout.o
peer.o
relay.o
sec.o
np.o
My test script includes the main header file, uttu.hpp, which itself refers to the np header file, under the name of protocols.hpp
The path to the archive file is correct, the archive itself contains the correct object file, and the test script refers to the main header file, which includes the correct definitions.
I'm stuck on what could be going wrong.
