same problem too. I installed gcc with 'yum install gcc' successfully. So why does it say that gcc doesn't work? I used ISPConfig-2.2.8 on Centos 4.4 after doing perfect install setup. Here's the shell output: --------------------------------------- Configuring libtool checking build system type... i686-pc-linux-gnu checking for ld used by gcc... /usr/bin/ld checking if the linker (/usr/bin/ld) is GNU ld... yes checking for /usr/bin/ld option to reload object files... -r checking for BSD-compatible nm... /usr/bin/nm -B checking how to recognise dependent libraries... pass_all checking for object suffix... o checking for executable suffix... no checking for c++... no checking for g++... no checking for gcc... gcc checking whether the C++ compiler (gcc ) works... no configure: error: installation or configuration problem: C++ compiler cannot create executables.

needed gcc-c++ too ok, after a simple google search I found out I also needed to 'yum install gcc-c++' .
