Вопрос:
Прежде всего, спасибо, что уделили мне время.
Я довольно долго искал эту ошибку здесь и там, но, похоже, не могу найти ее причину.
(Я совершенно уверен, что это нечто очевидное, что я просто не учел)
Итак, у меня есть эта библиотека : libraft.so, в котором есть экспортированные символы :
root@chuck-VirtualBox:/# nm -D /usr/local/lib/libraft.so

Однако, когда я пытаюсь скомпилировать, используя следующую команду :
g --std=c 2a -O3 -Wall *.cpp -o a.out `pkg-config --cflags --libs raft libuv`
(что переводится как )
g --std=c 2a -O3 -Wall *.cpp -o a.out -I/usr/local/include -L/usr/local/lib -lraft -luv -lrt -lpthread -lnsl -ldl
