如何将我的C程序链接到静态/动态库？

Question

I'm trying to link my C program to both a static and dynamic library to see the difference. How do I do that? I've made my own Makefile:

# ------ executable rule  -----------
app : app.o
        -gcc -g  app.o -o app

# ------ intermeditate object files rule (.o) -------
app.o : main.c
         -gcc -g -c main.c -o app.o

I've only shown you some of my Makefile as I think the rest is unnecessary.
I've tried to write -L. lstatic -L. lstatic after -gcc -g app.o -o app but it didn't work.

Read about invoking GCC . Order of arguments to gcc matters a lot!

You could use -static or -Bstatic

You can also explicitly link with static libraries, by giving some /usr/lib/libfoo.a (or some appropriate file path) argument at link time.

You'll better improve your Makefile to use existing builtin rules (try make -p ) and conventional variables, eg like here . Read the documentation of GNU make .
