gcc - /usr/bin/ld error: cannot find in /usr/local/lib though ldconfig list it, and path added to ld.so.conf

Question

I try to compile a C++ code, using a library I\'ve also compiled manually and installed in /usr/local/lib

ld, the linker, does not use external configuration files for that. ldconfig is for the loader, ld.so. Create a makefile if you want to set values for the linker somewhere.
