I can't compile anything on knoppix 3.3

[rex64]

Hi!

When i do ./configure the console says:

root@nerv:/home/rex# cd /home/rex/aMule-2.0.0rc2/aMule-2.0.0rc2/
root@nerv:/home/rex/aMule-2.0.0rc2/aMule-2.0.0rc2# ./configure

Why this error?

Don't know about your .configure problem, but you can get amule with apt.
If you have a debian style hd-install, start with typing "dselect update" to update your database, then type "apt-cache search amule" to find something installable, "apt-cache show amule" to check the version if you're interested, "apt-get -s -t unstable install amule" to see if it would install ok and leave out the -s for simulation to actually install if the output looked ok.

You are right, but aMule is only an example!
I have to compile a lot of other things, like many themes for KDE 3.2

Thanks anyway

Try "COLUMNS=150 dpkg -l|grep cpp" to see which you have installed, and then "apt-get -s install --reinstall packagename" for each one of them or just one if you find it in the config.log you got with the error message. If it works remove the -s for simulation.
