Hello Jeff, thanks for the answer, I solved it by also importing the library when compiling the shared one, I put my codes so that someone wants to try to do the same as me.
Make file.o ======= g++ -c -g3 -Wall -Werror -Wextra -fpic file.cpp -l:libcryptopp.a Make file.so ======== g++ -shared -o file.so file.o -lcryptopp -lpthread Now you can get your shared c++ library so you can use it in any language, in this case I use .so since I am in a linux environment.
