Missing conftest.c

Dear all,
I'm installing comedi on a Ubuntu 2.6.15 and I get an error from the ./configure 
command on the comedi.tar.gz installation:

checking for C compiler default output file name... configure: error: C compiler 
cannot create executables

I have gcc-4.0 virtually linked also to gcc to be sure there are no problems 
with version strings.
I am root so no problems with rights and permissions.


Trying the same thing with comedilib (after having unpacked comedilib.tar.gz) I 
receive a similar error because there is no conftest.c file neither in the 
current folder nor in all others (nothing in the two tar.gz files!).

Any suggestions? :-)
thanks
andrea
