To help to less experienced users to participate to such tests , I have prepared a skeleton algorithm for application of such tests . The skeleton algorithm needs to be completed to make it a usable algorithm . I am NOT so much experienced to prepare it completely , and reason is that for preparing that skeleton . I do NOT have sufficient knowledge to complete places specified by ... and to write scripts to apply some steps repeatedly without re-keying the necessary statements over and over with possible errors . If that skeleton is re-worked and completed to be usable , it is likely that more people will be able to apply such tests , including me . It should be written in such a structure that a FreeBSD user having knowledge to . install FreeBSD , . add packages , . perform file operations ( cp , mv , etc. ) , . apply scripts , . and other minimal knowledge to apply steps explicitly specified in the following algorithm , will be able to apply it . The algorithm may be tested by less experienced users to report its difficult to understand or apply parts . ( Similar algorithms may be generated and used to test other aspects . This may be a starting template for them . ) If you find useful , the following text may be completed and incorporated into a suitable page of wiki.freebsd.org or any other one ( by using already present copyright of the attached page ) . Thank you very much . Mehmet Erol Sanliturk To apply a complete test cycle about building FreeBSD from source by using CLang and LLVM compiling system , the following steps may be applied . Some of them may be already completed with respect to installed parts , and those steps may be skipped . (A) Install FreeBSD 8.0 Stable from ftp://ftp4.freebsd.org/pub/FreeBSD/snapshots/201004/FreeBSD-8.0-STABLE-201004-amd64-dvd1.iso OR ... (B) Login as root . Add the following packages in the listed order : pkg_add -rv llvm pkg_add -rv clang pkg_add -rv subversion-freebsd . . . The following script ... may be downloaded to apply that step . (C) Login as root . Check the versions of the following packages : ... To ensure that the latest versions of the following packages are already installed , apply the following statements : ... The following script ... may be downloaded to apply that step . (D) Study the following pages to apply required steps to build a bootable FreeBSD operating system : (E) http://wiki.freebsd.org/SubversionPrimer Apply the steps described in that page to construct a source tree in your local computer . The following script ... may be downloaded to apply that step . (F) http://wiki.freebsd.org/Tinderbox Apply the following steps to be able to build FreeBSD from sources with CLang by scripts : ... The following script ... may be downloaded to apply that step . (G) http://wiki.freebsd.org/BuildingFreeBSDWithClang Download latest Makefile from ... to compile FreeBSD sources by the CLang compiler by applying the following steps : ... by using scripts downloadable from : ... Apply the scripts to compile FreeBSD sources . (H) If compilation fails , prepare a message containing the following information ... and send it to the following address : ... ( A sample message text may be downloaded from .... ) Start from step ( ... ) . (I) After a successfull compilation , create a bootable CD or DVD or USB disk or USB stick : http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-cds.html Apply the following steps to create a bootable FreeBSD CD : OR http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/creating-dvds.html Apply the following steps to create a bootable FreeBSD DVD : OR If the testing computer can boot from a USB port ( This can be checked from BIOS and set from BIOS if BIOS allows booting from USB ) : http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/usb-disks.html Apply the following steps to create a bootable FreeBSD USB disk or stick : (J) On another computer , try to install the newly created FreeBSD operating system . If FreeBSD could not be booted successfully , prepare a message containing the following information : ... and send that message to the following address : ... ( A sample message text may be downloaded from .... ) If FreeBSD could be booted and installed successfully , prepare a message having the following information ... and attach dmesg file ... to the message and sent it to the following address ... ( A sample message text may be downloaded from .... ) (K) Execute the following programs in succession to test their workability : . . . (i) Program name : ... On successful completion ,send the message created from template downloadable from ... to the following address specified in template : ... On failure of execution ,send the message created from template downloadable from ... by attaching the following information ( or files ) ... to the following address specified in template : ...
