Your Linux distribution probably did come with a compiler; it just did not get installed. Oftentimes you can choose what type of installation to do (e.g., workstation install, developer install, server install, etc.), and the installer will just install the most commonly used programs for that type of installation. It probably works out that the type of install that you selected didn't install development related files. It almost certainly didn't install everything on the CDs - that almost never happens by default. The fact that the glibc headers didn't get installed while GCC did was probably an oversight on the part of Connectiva. Also, you tried to install glibc with the apt-get command you used, but what you needed to try to install is glibc-devel. Probably everything you need is on your CDs. You should get familiar with the CDs and how your distribution handles software installation (for example, does it use RPMs, Debian packages, etc.?). Once you know that, you should be able to find everything that you need to compiler programs for your system on the CDs. Good luck, Lyle -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of calvesmit@xxxxxxxxx I also tried apt-get install glibc using suchs CD's and system says I already have last glibc version installed!
