I have two simple questions regarding compiling Zaptel based on the confusing (to a kernel newbie) instructions at http://www.voip-info.org/wiki/view/Asterisk+Zaptel+Installation. The instructions say: For a Linux 2.6 kernel you may need to: modify the EXTRAVERSION statement in Makefile so it matches what you see in: cat /proc/version (see clarification in comments below) make modules_prepare and ln -s /usr/src/linux-2.6.9-5.0.3.EL /lib/modules/`uname -r`/build (replacing linux-2.6.9-5.0.3.EL with the appropiate value for your system) 1, My EXTRAVERSION statement in Makefile is blank but the 3 lines above contain the correct and current kernel: VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 13 Am I to simply write in the next line as: EXTRAVERSION = 2.6.13 ?? 2, The instructions say to make a soft link in the form of 2.6.13-5.0.3.EL I do not understand the -5.0.3.EL part. What should I put in where it says -5.0.13.EL ?? What is it about? Larry -- Larry Alkoff N2LA - Austin TX Using Thunderbird on Slackware Linux
