build(1) General Commands Manual build(1) NAME
build - build SuSE Linux RPMs in a chroot environment SYNOPSIS
build [--clean|--no-init] [--rpms path1:path2:...] [--arch arch1:arch2:...] [--root buildroot] [specfile|srcrpm] build --help build --verify DESCRIPTION
build is a tool to build SuSE Linux RPMs in a safe and clean way. build will install a minimal SuSE Linux as build system into some direc- tory and will chroot to this system to compile the package. This way you don't risk to corrupt your working system (due to a broken spec file for example), even if the package does not use BuildRoot. build searches the spec file for a BuildRequires: line; if such a line is found, all the specified rpms are installed. Otherwise a selec- tion of default packages are used. Note that build doesn't automatically resolve missing dependencies, so the specified rpms have to be sufficient for the build. If a spec file is specified on the command line, build will use this file and all other files in the directory for building the package. If a srcrpm is specified, build automatically unpacks it for the build. If neither is given, build will use all the specfiles in the current directory. OPTIONS
--clean remove the build system and reinitialize it from scratch. --no-init skip the build system initialization and start with build immediately. --list-state list rpms that would be used to create a fresh build root. Does not create the build root or perform a build. --rpms path1:path2:path3... Where build can find the SuSE Linux RPMs needed to create the build system. This option overrides the BUILD_RPMS environment vari- able. --arch arch1:arch2:arch3... What architectures to select from the RPMs. build automatically sets this to a sensible value for your host if you don't specify this option. --root buildroot Specifies where the build system is set up. Overrides the BUILD_ROOT enviroment variable. --useusedforbuild Tell build not to do dependency expansion, but to extract the list of packages to install from "# usedforbuild" lines or, if none are found, from all "BuildRequires" lines. This option is useful if you want to re-build a package from a srcrpm with exactly the same packages used for the srcrpm build. --norootforbuild --help Print a short help text. --verify verify the files in an existing build system. .spec FILE OPTIONS The build command interprets some special control comments in the specfile: # norootforbuild # needsrootforbuild build uses either user root or user abuild in the build system to do the build. For non-SUSE distros as well as since SUSE 10.2, the default build user is abuild. For 10.2 and before, the default build user is root. These two flags in the spec file allow to deviate from the defaults and force-set the build user to abuild and root (for # norootforbuild and # needsrootforbuild respec- tively. # needsbinariesforbuild provide the binary rpms that have been used to set up the build root in /.build.binaries within the build root. ENVIRONMENT
BUILD_ROOT The directory where build should install the chrooted build system. "/var/tmp/build-root" is used by default. BUILD_RPMS Where build can find the SuSE Linux RPMs. build needs them to create the build system. "/media/dvd/suse" is the default value which will do the trick if you have the SuSE Linux DVD mounted. BUILD_RPM_BUILD_STAGE The rpm build stage (-ba, -bb, ...). This is just passed through to rpm, check the rpm manpage for a complete list and descrip- tions. "-ba" is the default. You can use this to add more options to RPM. SEE ALSO
