Ubuntu Manpage: build - build SUSE Linux RPMs in a chroot environment

Provided by: obs-build_20210120-1_all

NAME

       build - build SUSE Linux RPMs in a chroot environment

SYNOPSIS

       build [--clean|--no-init] [--repo dir_or_url] [--repo...]  [--root buildroot] [recipefile]
       build --help
       build --verify

DESCRIPTION

       build  is  a tool to build binary packages in a safe and reproducible way.  The default is
       to build in a chroot sandbox, but build also supports building in a  virtual  machine  for
       better security.

       If  a recipe file is specified on the command line, build will use this file and all other
       files in the directory for building the package. If no recipe argument is provided,  build
       will search the current directory for a file.

       The build tool understands the following recipe file types:

       spec   A specfile used to generate rpms.

       src.rpm
              A source rpm, which will be unpacked for the build.

       kiwi   A kiwi config file used to generate a kiwi image.

       dsc    A dsc file used to generate Debian binary packages.

       PKGBUILD
              A file used to generate Arch Linux binary packages.

       build.collax
              A shell script used to generate a Collax binary package.

OPTIONS

--clean
Remove the build system and reinitialize it from scratch.

--no-init
Skip the build system initialization and start with build immediately.

--repo dir_or_url
Either a directory containing binary packages (optionally with repository
metadata), or a url pointing to some remote repository. Multiple --repo options can
be used so create a specific repository layering. Note that packages are searched
in the specified repository order, i.e. the first repository containing a package
with a specific name wins regardless of the version. As a special form,
'zypp://reponame' can be used to specify a system repository. 'zypp://' selects all
enabled system repositories. This is also the default if BUILD_RPMS is not set and
no --rpms or --repo option is used.

--dist distribution
Set the distribution. If this option is not given, build tries to guess the
distribution by looking at the available packages. The specified distribution can
either be a string like "11.2" or "sles9", "debian7", or the pathname of the build
configuration to use.

--root buildroot
Specifies where the build system is set up. Overrides the BUILD_ROOT enviroment
variable.

--help Print a short help text.

--norootforbuild
Force building with user abuild. Otherwise, build searches the recipe file for a
"needsrootforbuild" hint to decide what user to use.

--list-state
list packages 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 packages needed to create the build system. This option
overrides the BUILD_RPMS environment variable. This option is deprecated, use
--repo instead.

--arch arch1:arch2:arch3...
What architectures to select from the RPMs. build automatically sets this to a
sensible value for your host if you do not specify this option so you should almost
never need it.

RPM BUILD SPECIFIC OPTIONS

       --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.

       --stage
              Pass a stage option to rpmbuild. The default is -ba.

       --target
              Call rpmbuild with a target option. This can be used for cross building.

       --verify
              Verify the files in an existing build system.

VIRTUAL MACHINE SPECIFIC OPTIONS

--xen --kvm --uml --qemu --emulator --zvm --lxc
Sets a specific vm type.

--vm-type type
As above.

--vm-disk file
Specifies the location of the disk image to use. If this option is not given,
buildroot.img is used (e.g. /var/tmp/build-root.img).

--vm-disk-size size_in_mb
Specify the size of the disk image to create.

--vm-disk-filesystem type
Sets the filesystem type to use when creating the disk image. The default is to use
the ext3 filesystem.

--vm-swap file
Specifies the location of the swap file to use. If this option is not given,
buildroot.swap is used (e.g. /var/tmp/build-root.swap).

--vm-swap-size size_in_mb
Specify the size of the swap file to create.

--vm-memory size_in_mb
Sets the desired memory size of the virtual machine.

--vm-kernel kernel_file
Set a specific kernel to boot in the virtual machine.

--vm-initrd initrd_file
Set a specific kernel to boot in the virtual machine.

--vm-disk-clean
Force the recreation of the disk image.

--vm-telnet PORT
Is forwarding PORT to a telnet session inside of the VM. Specify also needed extra
packages via -x parameter, usually: --vm-telnet 1234 -x telnet-server -x net-tools
And connect from the host via: telnet localhost 1234
NOTE: The telnet server gets started after all packages got installed.

RECIPE FILE OPTIONS

       The build command interprets some special control comments in the recipe file:

       # 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 respectively.

       # 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. See the --root option.

       BUILD_RPMS
              This can be used instead of the --rpms option. Deprecated.

       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 descriptions.  "-ba" is the default. You should
              probably use the --stage option instead.
