configure: error: C preprocessor “/lib/cpp” fails sanity check
See `config.log’ for more details.
Now for a quick introduction about Feather Linux. Feather is a Linux distribution which is able to run completely off a small cd or a thumbdrive, fitting in less than 128MB! Its a modification of DSL (Damn Small Linux), which is a Knoppix remaster, and Knoppix in turn is a cool modified Debian distro meant to boot up completely from a cd.
Why Feather? Perphaps because it works compared to other distros I tried for my old pc (PII 300mhz which doesnt have a working cdrom drive) . It detects all my hardware, comes with enough nifty packages, light on resources, making it relatively fast yet powerful. The fact its based on Debian, I can use the fravorite tool apt.
Now for the sanity part. Perphaps I screwed up some where configuring the system, and Feather, Knoppix, and Sarge -specific packages might have conflicted. Any software requring compiling normally throws that sanity check failure.
In this example, I’m trying to compiling the latest lilypond release, and as usual, failure.
And yes, I using ssh2 because my room was used by others as this time.
Seems that not only the C pre-processor lost it sanity, I too.
I crazily type apt-get remove cpp thinking that, maybe removing and reinstalling it would work.
Before I know it, many packages are removed too. Something like a few utils along with X and other stuff disappeared.
So what I did was basically follow this “obsolete” guide on configuring Feather posted on the forums.
And if you are wondering how I surf the net while X is down, I’ve been using links, a text-based WWW browser. And if “text-based” doesnt amuse you, look at the following shots.
And back to the sanity stuff. Arr! Making me lose my sanity. I’ve been trying all ways to work this whole day, without success till now. I could trace the error down only when installing the “unstable”, or “testing” deb of xserver-common. Running apt-get install xserver-common gets…

Who says Linux doesnt have a BSOD?
Moral for today: Don’t try apt-get remove cpp

installing g will make your system sane again…
sudo apt-get install g
your filter is removing the plus sign ” ” which obviously makes the command listed above not the correct command.
it would be
sudo apt-get install gpp (where p and p are the plus sign and another plus sign)
