build: get rid of host.mk

2017-02-26T12:31:44Z

Defined required host related variables in toplevel.mk instead Signed-off-by: Felix Fietkau

build: add buildbot specific config option for setting defaults

2017-02-14T13:18:35Z

This can be used to tweak the buildbot behavior without having to change buildbot's configuration. It will also allow us to add more aggressive clean steps (e.g. on toolchain changes), which would break developers' workflows if enable by default. Signed-off-by: Felix Fietkau

imagebuilder: make submake invocations less verbose

2017-02-01T23:13:49Z

Use silent make invocations for sub-makes like build_image or checksum to avoid bloating the IB output with non-status info. Signed-off-by: Jo-Philipp Wich

build: introduce STAGING_DIR_IMAGE

2017-01-27T15:53:31Z

Introduce a new location STAGING_DIR_IMAGE which is intended to be used by bootloader iamges and similar image-related artifacts. This directory is guaranteed to be persistent across kernel upgrades which might involve a removal of KERNEL_BUILD_DIR and is guranteed to be bundled with the image builder.

imagebuilder: properly escape single quotes in device titles

2017-01-26T09:16:32Z

The name "Plat'Home OpenBlocks AX3" causes the imagebuilders "make info" command to fail with: bash: -c: line 0: syntax error near unexpected token `(' bash: -c: line 0: `echo; [...]' Makefile:99: recipe for target '_call_info' failed Properly escape single quotes to avoid breaking the echo commands.

build: rework library bundling

2017-01-10T11:27:28Z

Rework the bundle-libraries.sh implementation to use a more robust approach for executing host binaries through the shipped ELF loader and libraries. The previous approach relied on symlinks pointing to a wrapper script which caused various issues, especially with multicall binaries as the original argv[0] name was not preserved through the ld.so invocation. Another down- side was the fact that the actual binaries got moved into another directory which caused executables to fail looking up resources with paths relative to the executable location. The new library wrapper implements the following improvements: - Instead of symlinks pointing to a common wrapper, each ELF executable is now replaced by a unqiue shell script which retains the original program name getting called - Instead of letting ld.so invoke the ELF executable directly, launch the final ELF binary through a helper program which fixes up the argv[0] argument for the target program - Support sharing a common location for the bundled libraries instead of having one copy in each directory containing wrapped binaries Finally modify the SDK build to wrap the staging_dir and toolchain binaries which allows to use the SDK on systems with a different glibc version.

target/imagebuilder: Switch to xz compression instead of bz2

2016-10-15T09:36:51Z

Switch to xz compression instead of using bz2. Saves about 20% of total size (ar71xx) Signed-off-by: Daniel Engberg

target/{sdk,imagebuild}: Fix for symlink-tree

2016-09-29T22:39:25Z

With symlink tree some directories are just symlinked which means IB and SDK end up with a symlink instead of an actual directory; this fixes the missing files by dereferencesing the directories instead of copying the symlinks. Signed-off-by: Daniel Dickinson
