This week, a kind of rebuild for precise pangolin in the disguise of the armhf bootstrap did end. The build did expose some ARM unspecific build failures; please use the information from the armhf build logs to address these build failures. Please use the ftbfs pages to gather more information:
- http://qa.ubuntuwire.com/ftbfs/ (not yet showing armhf) This mostly shows failures introduced by syncs from Debian unstable (Debian didn't yet file bug reports after introducing the -Werror=format-security default).
- http://qa.ubuntuwire.org/ftbfs/primary-precise-armhf.html Shows armhf and armel build failures. Look at build failures which appear on armhf but not armel. These are likely build failures for other architectures as well.
There are some generic issues found in more than one package:
- default CFLAGS/CXXFLAGS include -Werror=format-security. Fixes are easy; don't stop fixing the first occurrence, but complete a local build.
- Gnome pkgconfig files dropping -lm from Libs, and other packages not explicitly linking with -lm (resulting in symbols like "sqrt" and "pow" not found).
- libreadline-dev dropping build dependency on libncurses-dev, and libncurses introducing a new libtinfo library.
ARM (hf) specific issues include
- compilers not yet built on armhf (gnat, fpc, ocamlopt), or not yet having the correct defaults (clang).
- packaging mentioning armel only, but not armhf; usually needs fixes in both the control and rules files. http://people.canonical.com/~adconrad/universe-armel-armhf_differences might help with these although it includes all the packages build depending on gnat and fpc.
- hard float issues, needing porting work. known ones are libreoffice, ocamlopt and fpc, but there will be more ...
The armhf precise archive is installable with debootstrap(1) in a chroot on any armel Ubuntu/Linaro release.
Thanks to Adam Conrad for driving the bootstrap, to Loic Minier for fixing ARM issues on the fly, to the Losa's for keeping the build farm alive, and many others.
