This chapter describes how to build OpenAFS from source code. storing OpenAFS source in volume creating volume for OpenAFS source volume for OpenAFS source source (AFS) storing in AFS volume files OpenAFS source Working on an AFS client machine, login to AFS as a administrative user, then perform these steps to load the OpenAFS source tree from the OpenAFS Source Distribution. commands vos create src.afs volume vos commands create src.afs volume src.afs volume volume creating src.afs creating src.afs volume Create and mount a volume for housing the OpenAFS source tree. These instructions name the volume src.afs and mount it at the /afs/cellname/afs/src directory. Setting the -maxquota argument to 0 (zero) sets an unlimited quota on the volume, which enables you to copy all of the files into the volume without exceeding its quota. If you wish, you can set the volume's quota to a finite value after you complete the copying operation. At that point, use the vos examine command to determine how much space the volume is occupying. Then issue the fs setquota command to set a quota that is slightly larger. # vos create <machine name> <partition name> src.afs -maxquota 0 # cd /afs/.cellname # mkdir afs # fs mkmount afs/src src.afs # vos release root.cell # fs checkvolumes Download the latest stable OpenAFS source distribution (openafs-src.X.Y.Z.tar.gz) from openafs.org to the local /tmp directory. downloading source files from openafs.org In the local /tmp directory, unpack the source archive. # cd /tmp # gzip -dc openafs-src-X.Y.Z.tar.gz | tar xvf - unpacking source files from the archive Copy the source files from the unpacked archive into the newly created volume. # cd /tmp/openafs-X.Y.Z # cp -rp * /afs/.cellname/afs/src source (AFS) compiling compiling AFS from source building AFS from source The OpenAFS distribution uses the autoconf program and Makefiles for compiling the OpenAFS software. Create a subdirectory under the /afs/.cellname/afs directory for each system type for which you will build AFS binaries. Creating and mounting a volume for each system type is recommended, but you can also simply use the mkdir command. If you create a new volume, grant it an unlimited quota to avoid running out of space during the build process. # cd /afs/.cellname/afs If creating a new volume: # vos create <machine name> <partition name> sysname -maxquota 0 # fs mkmount sysname sysname If not creating a new volume: # mkdir sysname In the directory for each system type, create subdirectories called dest, dest/bin, and obj. If you plan to use the @sys variable in pathnames that refer to these directories, then you must use the conventional system names listed in the OpenAFS Release Notes. # cd sysname # mkdir dest # mkdir dest/bin # mkdir obj Create the indicated directories and symbolic links in the /afs/.cellname/afs directory. # cd /afs/.cellname/afs # ln -s @sys/dest dest # ln -s @sys/obj obj # ln -s . PARENT # ln -s src/Makefile Makefile The following is an example directory listing for the /afs/.cellname/afs directory after completing the preceding steps. It includes two example system types. lrwxr-xr-x admin 12 Jun 18 11:26 Makefile->src/Makefile lrwxr-xr-x admin 1 Jun 18 11:26 PARENT -> . lrwxr-xr-x admin 9 Jun 18 11:25 dest -> @sys/dest lrwxr-xr-x admin 8 Jun 18 11:25 obj -> @sys/obj drwxrwxrwx admin 4096 Jun 18 11:24 rcs drwxrwxrwx admin 2048 Jun 18 11:27 rs_aix42 drwxrwxrwx admin 2048 Jun 18 11:10 src drwxrwxrwx admin 2048 Jun 18 11:27 sun4x_56 (Optional) By default, the build procedure writes its results into a destination directory for each system type called /afs/.cellname/afs/sysname/dest. To write the results to a different destination directory, create a link from the dest directory to it. # cd /afs/.cellname/afs/sysname # ln -s full_path_of_alternate_directory dest commands For each system type you plan to build, run the following commands on a machine of that system type: # cd /afs/cellname/sysname # ../src/configure # make # make dest commands make configure command make command commands configure Working in the /afs/.cellname/afs directory on a machine of the system type for which you are building AFS, issue the make install command.
