./configure fail -- gcc etc

Hi, I am getting a "Cannot find compiler message" from a configure script yet I know gcc ( I know as it wasn't by default and I had to install it later) is there -- how can I tell the script where it is. THis seems to be the relevant part of the script. Many TIA F # # $CXX # $echo 'Checking C++ compiler... \c'; cat <<EOF >$tmp_file.C; #include int main(int, char **) { cout << "hello" << endl; return 0; } EOF CXX=unknown; for i in "CC" "g++"; do if $i -c $tmp_file.C 2>/dev/null; then CXX="$i"; break; fi; done; if test "$CXX" = unknown; then $echo "Error: Could not find a working C++ compiler."; exit 1; fi; $echo "use \"$CXX\"";
