iv. Host System Requirements

You should be able to build a CLFS system from just about any Unix-type operating system. Your host system should have the following software with the minimum versions indicated. Also note that many distributions will place software headers into separate packages, often in the form of “[package-name]-devel” or “[package-name]-dev”. Be sure to install those if your distribution provides them.

To see whether your host system has all the appropriate versions, run the following:

cat > version-check.sh << "EOF"
