Question

This is part of a homework assignment. What we have to do is write a makefile to compile previous homework solutions. The solutions were provided by the professor, and they’re what will be used to test our makefiles. One of the files has an #include "quicksort.c".

I know the usage of something like that is discouraged, but that doesn’t really help me 🙂

What would be the best approach to getting the two files to compile (the file quicksortTest.c, which includes quicksort.c, and quicksort.c itself)?

What I currently have as part of my makefile is the following:

    quicksort: quicksort.c quicksortTest.c
               $(CC) quicksortTest.c quicksort.c -o quicksortTest

Where quicksortTest.c has the #include "quicksort.c".

When I try it, I get several gcc compiler errors… ideas?

Answer 1

Don’t pass quicksort.c to gcc. Since you are including the file you should not compile it seperately:

quicksort: quicksort.c quicksortTest.c
       $(CC) quicksortTest.c -o quicksortTest
