sanity check failed for g++

I'm trying to compile mpeg4ip on a Fedora Core2-machine and I always get the same anxious message, when I run ./configure:

Code:

checking how to run the C preprocessor... g++
configure: error: C preprocessor "g++" fails sanity check
See `config.log' for more details.

config.log says:

Code:

[.............]
| #endif
|                      Syntax error
configure:3926: g++  conftest.c
./configure: line 1: g++: command not found
configure:3932: $? = 127
configure: failed program was:
| #line 3912 "configure"
| /* confdefs.h.  */
[..............]
BILLS_CPPWARNINGS=''

CCDEPMODE='depmode=gcc3'
CFLAGS='-g -O2'
CPP='g++'
[..........................]
#define PACKAGE_VERSION ""
#define VERSION "1.1"

configure: exit 1

So, I've seen thousands of threads that treat this problem, but not one could solve the mine.

- gcc is installed
- X11lib is installed
- cpp is installed....

Here is what I get when I enter...:

Code:

ls -l /lib/cpp
lrwxrwxrwx  1 root root 14  2. Nov 11:34 /lib/cpp -> ../usr/bin/cpp

And my c++ runs well, usually, compiling is no problem on that machine.
Yet, what can I do? Have I goto change something in configure.in?

Is g++ installed?

gcc is the Gnu C Compiler. g++ is the Gnu C++ compiler, they're different.

I'm running Fedora Core 2 and just downloaded mpeg4ip and ran configure and had no problems. I realize it isn't the best answer, but if I were you, I'd make sure I had g++ installed.

For me, cpp is the package you're mentioning.

Is there another package I should have installed? Which packages do you mean with the "g++"-package? For me, cpp is meant, cause it's the only c++-package I could find for fedora 2.

Please explain me, which packages you've meant (and where I can download them). Thanks.
