There are two thing I would like to address to here:
1.) In this LInux box I have two accounts; root and myaccount, when I
type:
$ pkg-config gtkmm-2.4 --cflags

I get the following message:

Package gtkmm-2.4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gtkmm-2.4.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gtkmm-2.4' found

How can I change that?


2.) I wrote this simple Makefile, which by the way is my first
Makefile, it is a test Makefile to make sure that everyting works. The
helloworld.??p and the main.cpp are copy/pasted from the manual's
book. So, I would say that they can be trusted.
And here is copy of my Makefile.jme

What Linux?  Distro and version please.  Helps us help you.  :-)

Are you running Slackware or one of its derivatives (ie., Zenwalk)?
Where did gtkmm-2.4 come from?  How did you get it?  What did you do
with it once you got it?

Where is gtkmm-2.4.pc?

find / -type f -name 'gtkmm-2.4.pc' -print

is the brute force method.  Alternatively, if updatedb has been run
recently, "locate gtkmm-2.4.pc" might find it for you.

I see "helloworld.??p" here.  What's that?  I assume we've a charset
collision; not your fault (I think) and pretty common these days
(drat).

We cannot trust your typing, sorry:

>  # Pogrammer:

# Programmer:

>  helloworld.o: helloworld.hpp

What is an ".hpp" file?

>  main.cpp:1:24: gtkmm/main.h: No such file or directory

Where's gtkmm/main.h?

>  In file included from main.cpp:2:
>  helloworld.hpp:4:26: gtkmm/button.h: No such file or directory
>  helloworld.hpp:5:26: gtkmm/window.h: No such file or directory

Ditto.

>  In file included from main.cpp:2:

Looks to me like you're missing the part where you tell the compiler
which libraries to link with.

>  helloworld.hpp:8: error: `Window' is not a class or namespace
>  helloworld.hpp:8: error: invalid base-class specification

Ditto.

>  helloworld.hpp:19: error: syntax error before `::' token

Another typo?

>  main.cpp:12:2: warning: no newline at end of file

Trivial warning.  Add a blank line at the end of main.cpp to eliminate
it.

I'd say you're right on track for a newbie (no offense meant).  Just
keep banging your head on that wall (google, man pages, re-read your
book), and it'll eventually fall over.  We've all been there, myself
included.

Other things you might explain:

- How did you get here?  What's the book you're reading?

- What are you really trying to do, and with what?  What is gtkmm?
Where'd you get it (if you got it), and in what form was it
received (.rpm, .deb, .tgz, .tar.gz, ...)?  Why is it involved in
your "helloworld" example proggie?

- Consider testing something even simpler than helloworld.C++ - try
helloworld.c:

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char *argv[] ) {

printf( "Hello World.\n" );

exit( EXIT_SUCCESS );
}

Then:

"gcc -o helloworld helloworld.c -Wall"

(just to ensure crucial underlying bits are there and functional).

Have fun.

Probably you need to install libgtkmm-2.4-dev (the development libraries
for developing C programs that link to libgtkmm-2.4).

I'm assuming you're using Debian/Sarge.

Just to be supportive jamil, there is a lot of good advice in s. keeling's
email. Some of it is obvious and some is 'between the lines'.

Most helpful posters like to see what effort you've already put into a
problem before they spend much effort trying to write out what can turn
out to be complicated answers. My guess would be that Dan C, for example,
would like your current question better than the way you previously asked
your questions.

I will mention one of my own tweaks, whenever I see 'help' (especially
capitalised with exclamation points), I think newbie. That often
translates into someone who is very difficult to help and I know some
people ignore those. In the present case, "My First Makefile" as a subject
says it all, you wouldn't be here if you weren't seeking help. But, you've
been getting good help here and have only run into a little impatience.
