MacOS -- how to link a dynamic library with a relative path using gcc/ld

If you are trying to understand dynamic linking, this question is likely to be of interest. One of the answers to that question provides a wonderful example of creating and using a dynamic library. Based on it, I some simple files: main.c: ``` extern void someFunction (int x); int main (int argc, char** argv ) { someFunction(666); } ``` mylibrary.c: ``` #include <stdio.h> void someFunction (int x) { printf ("\nsomeFunction called with x=%d\n", x); } ``` makefile: ``` main: mylibrary.c main.c gcc -c mylibrary.c gcc -dynamiclib -current_version 1.0 mylibrary.o -o libmylibrary.dylib gcc -c main.c gcc -v main.o ./libmylibrary.dylib -o main clean: rm *.o rm main rm *.dylib ``` So far, everything works great. If I make and then enter ./main at the command prompt, I see the expected output: ``` someFunction called with x=666 ``` Now, I want to mix things up a little. I've created a directory hidelib, which is a subdirectory of my main directory. And I'm adding one line to my makefile: ``` main: mylibrary.c main.c gcc -c mylibrary.c gcc -dynamiclib -current_version 1.0 mylibrary.o -o libmylibrary.dylib gcc -c main.c mv libmylibrary.dylib hidelib # this is the new line clean: rm *.o rm main rm hidelib/*.* ``` Now, I want to add another line to the makefile so it will find libmylibrary.dylib in the hidelib subdirectory. I want to be able to run ./main in the same way. How can I do that? EDIT: Thanks for the response. Having lots of options is wonderful, but a beginner just wants one concrete option that works. Here is what I am trying for the last line, but clearly I don't understand something. The makefile executes without errors, but at runtime it says "library not found." ``` gcc main.o -rpath,'$$ORIGIN/hidelib' -lmylibrary -o main ```
