Hello!
I have a problem when installing eggdrop.
When i do ./configure it shows me this error - C preprocessor "/lib/cpp"
Here is the log

checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no
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 how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check

do you have kernel-headers package installed?
ls /var/log/packages/ | grep kernel-headers

no i don't.
but i will try to install it.
Should it fix my problem?

now i have them

but still no efect, still the same problem !

does this happen only when compiling eggdrop or other programs give this error to?
and check if you have gcc-g++ package installed to

i didn't install headers correctly.
so now when i have done it correctly ./configure doesn't give out any kind of errors.
tnx a lot
