That or perhaps try say: mkdir ~/centos5 cd ~/centos5 wget http://mirrors.kernel.org/centos/5/os/x86_64/CentOS/glibc-devel-2.5-118.x86_64.rpm wget http://mirrors.kernel.org/centos/5/os/x86_64/CentOS/glibc-headers-2.5-118.x86_64.rpm wget http://mirrors.kernel.org/centos/5/os/x86_64/CentOS/kernel-headers-2.6.18-371.el5.x86_64.rpm for i in *.rpm; do rpm2cpio $i | cpio -id done and then compile with g++ -nostdinc `g++ -v -E -xc++ /dev/null 2>&1 | sed -n '/^#include </,/^End of/{/\/usr\/include/d;s/^ \//-isystem /p}'` -isystem ~/centos5/usr/include/ This command will use all standard C++ search paths except for /usr/include, and will use ~/centos5/usr/include/ instead of that. Similarly for various other distros. Jakub
