Task: Linking Multiple Files

Access the directory tasks/multiple-link/support/example/. We want to follow the linking commands from multiple C source files: main.c, add.c, sub.c.

As in the previous exercises, there are three subdirectories for three different scenarios:

• a-no-header/: external function declarations are made directly in the C source file (main.c)
• b-header/: external function declarations are made in a separate header file (ops.h)
• c-lib/: external function declarations are made in a separate header file, and linking is done using a static library

In each subdirectory, we use the make command to compile the executable file main.

Access the directory tasks/multiple-link/support/diy/. We want to compile and link the source files in each subdirectory, following the model of the previous exercise.

Copy the Makefile files and update them in each subdirectory to obtain the executable file.
