Knoppix 3.4 compiling problems cpp

**Frost** · 06-08-2004, 11:28 AM

hi,
most of the time when I try to compile a program I get the following message:

Code:

configure: error: C preprocessor "/lib/cpp" fails sanity check

I reinstalled cpp with apt-get. And I'm running from a HD install with kernel 2.6.5.

/lib/cpp --version

Code:

cpp (GCC) 3.3.3 (Debian 20040422)

Someone who knows how to solve this?

thx,

Which cpp did you get?

Could it be that gcc and cpp are different versions?

Have you tried removing cpp and compiling?

I'm a bit puzzled by this as I've never, on any Linux system, had to install cpp as a seperate entity. Even when I've had to install gcc the pre processor has been sorted by whichever/whatever installation tool I used.

Try g++ from GCC which is included in KNOPPIX. I never had a problem with it!

Good Luck,

cpp, gcc and g++ are all version 3.3.3, I have removed and reinstalled these packages but without result. (apt-get)

How can I use g++ instead of cpp, or what do you mean AJG? I'm just doing ./configure, and that's what's giving me the CPP errror...

thx for the response so far,
F.

I wonder if you're using the wrong version of GCC for that particular package?

Generally, the later the version of GCC is, the more ansi compliant (and the fussier) it is, especially with regard to C++.

What's the output of

gcc -v

?

You'll probably find there's a symlink in /usr/bin: you could try pointing that to the other version (or re-setting the environment).

If all else fails, contact the developer of the package.

gcc -v gives:

Code:

I really don't see what's wrong... (maybe 'cause I'm not really poweruser...but I'm working on it...:P)

c ya,

What are you trying to compile?

I tried several sources to compile, kbootsplash, modules for my printer/scanner, lirc, muse, some tv apps, ... most of the things are also available in debian packages but not all of them...
