g++ include all /usr/include recursively

Question

I\'m trying to compile a simple program, with

#include 

The path to gtkmm.h is /usr/include/gtkmm-2.4/gt

I guess you are not using a makefile? The only thing that could be annoying is having to type the long -I option each time you compile your program. A makefile makes it a lot easier.

For example, you could modify the hello world makefile from wikipedia to something like the following:

INC=-I/usr/include/gtkmm-2.4/

helloworld: helloworld.o
    g++ -o $@ $<

helloworld.o: helloworld.c
    g++ $(INC) -c -o $@ $<

.PHONY: clean

clean:
    rm -f helloworld helloworld.o
