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

I use gcc 3.4.4 (CodeSourcery ARM 2005q3-2) to install lighttpd, and following error:

See `config.log' for more details.

I searched google and saw many forums which this problem, but i can't check it.
What can i do?
I checked that g++ is installed.

I had similar errors trying to install Fuse I believe, or ntfs-3g, in Mandrake 10.2 (I think), I did not have gcc-c++ installed, or make for that matter, possibly even kernel-source. Having many distros is starting to have an effect. But basically there is some building tools (essentials) not installed or the wrong version installed as you mention you are using gcc-34, possibly libgcc according to where things came to a halt.
Which distribution is this?

Thanks, ernie and Junior Hacker.

config.log reports same error and so many other errors...
and I use embedded kernel on ARM9, so no distribution.
anyway, I resolved:
I just skipped C Preprocessor sanity check with editing "configure" file.
