configure: error: Fluxbox requires the X Window System libraries and headers.
Tuukka:/home/duukkis/paketit/fluxbox-0.1.14#

I have xlibs= X Window System libraries installed but I don't know the name of that header package. What's the name of it?

well when it doesn't find the includes and libraries you can specify it with the configure script with the following syntax::
./configure --x-includes=DIR --x-libraries=DIR
where you will replace DIR with the appropriate path.

You will need to install the "xlibs-dev" package.

# apt-get install xlibs-dev

I installed that xlibs-dev package successfully and now I have done the ./configure but when I try to execute Makefile (./make) in root it says:

bash: ./make: No such file or directory

There are INSTALL help file in that fluxbox dir and they tell that I should make commands:

./configure
./make
./make install (Don't need in Debian I think)

So what's wrong?

./configure
make
make install

duukkis@Tuukka:~/paketit/fluxbox-0.1.14$ make
bash: make: command not found
duukkis@Tuukka:~/paketit/fluxbox-0.1.14$ make install
bash: make: command not found
duukkis@Tuukka:~/paketit/fluxbox-0.1.14$

???

umm looks like you havnt got make installed, although i find that very suprising, whats the output of 'which make' if its not there then you'll need to install it i think the debian package manager is apt-get but a debian person can tell you more

Like kev82 says, look at the output of `which make', and if you don't have make then run `apt-get install make'.

In fact you don't need to do any of this. Just run `apt-get install fluxbox'. That will install version 0.1.14. That's really the easiest way to do it.
