ARM builds

Hi, Can you tell me what kind of systems you use for building for the armhfp architecture, and where to buy them? My group would like to start supporting that architecture but I can't find anything concrete. Or is emulation the way to go here? Thanks, -Mat

New Mock release (1.4.11)
by Miroslav Suchý 13 Jun '18

13 Jun '18

I just released Mock 1.4.11. Copy of release notes: https://github.com/rpm-software-management/mock/wiki/Release-Notes-1.4.11 Released on 2018-06-12. Features: Previously you were able to only build for compatible architectures. I.e., you can build i386 package on x86_64 architecture. When you tried to build for incompatible architecture, you get this error: $ mock -r fedora-28-ppc64le shell ERROR: Cannot build target ppc64le on arch x86_64, because it is not listed in legal_host_arches ('ppc64le',) Now, you can build for any architecture using new option --force-arch ARCH. GH#120 You have to have installed package qemu-user-static, which is a new soft dependence. Try this: $ sudo dnf install qemu-user-static $ mock -r fedora-28-ppc64le --forcearch ppc64le shell and you get the prompt in PPC64LE Fedora. You can do this for any architecture supported by QEMU. Note: Do not confuse --forcearch and --arch which are very different options. Mock previously only supported GNU Tar. Now Mock supports BSD Tar as well. GH#169 There is a new option in config available: # You can configure which tar is used (for root cache and SCM plugin) # valid options are: "gnutar" or "bsdtar" # config_opts['tar'] = "gnutar" Be aware that if you created a cache using gnutar then you cannot extract it using bsdtar. Therefore when changing this option, you have to scrub all caches. There is a new config option: # name of user that is used when executing commands inside the chroot # config_opts['chrootuser'] = 'mockbuild' This can be changed to different value. E.g., 'root'. However, be aware that any other value than 'mockbuild' is not tested by upstream. There is initial support for MicroDnf GH#76 Be aware the due MicroDNF is missing --installroot option, the buildroot and build dependencies are still installed by DNF. These are new options related to MicroDNF: # config_opts['microdnf_command'] = '/usr/bin/microdnf' ## "dnf-install" is special keyword which tells mock to use install but with DNF # config_opts['microdnf_install_command'] = 'dnf-install microdnf dnf dnf-plugins-core distribution-gpg-keys' # config_opts['microdnf_builddep_command'] = '/usr/bin/dnf' # config_opts['microdnf_builddep_opts'] = [] # config_opts['microdnf_common_opts'] = [] # config_opts['microdnf_command'] = '/usr/bin/microdnf' config_opts['package_manager'] = 'microdnf' Right now, Mock does not ship any config which use this package manager. There is a new option --spec, which you can use to build an SRPM. # dnf download --source foo # rpm2cpio foo.src.rpm | cpio -dimv (Add/modify compilation flags in .spec file) # mock --spec foo.spec foo.src.rpm --postinstall (or) # mock --spec foo.spec --sources ./ Bugfixes: The file /etc/resolv.conf is now empty when networking is disabled. RHBZ#1514028 This reduces timeout when code tries to connect to a network. Note that option config_opts['use_host_resolv'] changed from True to False as networking is disabled by default too. Note that --enable-network automatically set config_opts['use_host_resolv'] to True now.
