problem compiling source

[lewisdw]

I'm trying to compile some apps from source, and ./configure fails on everything I try with the following:

...
checking for suffix of executables...
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ANSI C... none needed
checking dependency style of gcc... gcc3
checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check


What files/libraries am I missing? This is knoppix 4 (with a debian type install to the hdd).

Thanks

Do you have cpp installed?
markus@mrk-fujibox:~$ ls -l /usr/bin/cpp*
lrwxrwxrwx 1 root root 16 Jul 13 20:54 /usr/bin/cpp -> /usr/bin/cpp-3.3

markus@mrk-fujibox:~$ dpkg -l|grep cpp
ii cpp 4.0.0-2 The GNU C preprocessor (cpp)
ii cpp-3.2 3.2.3-9 The GNU C preprocessor
ii cpp-3.3 3.3.6-7 The GNU C preprocessor
ii cpp-4.0 4.0.1-2 The GNU C preprocessor

Best to use the same cpp and gcc versions.

Yes, it's installed:

wayne@erin:~$ ls -l /usr/bin/cpp*
lrwxrwxrwx 1 root root 7 Jul 11 21:08 /usr/bin/cpp -> cpp-3.3
-rwxr-xr-x 1 root root 88876 May 14 19:34 /usr/bin/cpp-3.3

And gcc is pointing to the same version?
markus@mrk-fujibox:~$ ls -l /usr/bin/gcc*

I'm not sure about that. Here's my output:

Hmm, try reinstalling the packages or switch to 4 with:
rm /usr/bin/gcc /usr/bin/cpp
ln -s /usr/bin/gcc-4.0 /usr/bin/gcc
ln -s /usr/bin/cpp-4.0 /usr/bin/cpp
