* tools: add fakerootThomas Petazzoni2020-08-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | SELinux support requires setting the appropriate SELinux security context to files and directories, which needs to happen at build time in order to support read-only root filesystem scenarios. In order to create these security contexts, we will have to run some SELinux-specific tools on the host machine, but that requires root access. This adds support for fakeroot, which the build process will use to run the SELinux security context creation and the image creation.

* build: make prefix mapping of debug information optionalFelix Fietkau2020-08-061-1/+1
| | | | | | | | | | | | | | Remapping the local build path in debug information makes debugging using ./scripts/remote-gdb harder, because files no longer refer to the full path on the build host. For local builds, debug information does not need to be reproducible, since it will be stripped out of packages anyway. For buildbot builds, it makes sense to keep debug information reproducible, since the full path is not needed (nor desired) anywhere. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: improve ccache supportRoman Yeryomin2020-07-111-0/+3
| | | | | | | | | | | | | | | | | | Set CCACHE_DIR to $(TOPDIR)/.ccache and CCACHE_BASEDIR to $(TOPDIR). This allows to do clean and dirclean. Cache hit rate for test build after dirclean is ~65%. If CCACHE is enabled stats are printed out at the end of building process. CCACHE_DIR config variable allows to override default, which could be useful when sharing cache with many builds. cacheclean make target allows to clean the cache. Changes from v1: - remove ccache directory using CCACHE_DIR variable - remove ccache leftovers from sdk and toolchain make files - introduce CONFIG_CCACHE_DIR variable - introduce cacheclean make target Signed-off-by: Roman Yeryomin <roman@advem.lv>
* rules.mk: remove "$(STAGING_DIR)/include"Sebastian Kemper2019-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "$(STAGING_DIR)/include" was carried over from buildroot-ng to OpenWrt in commit 60c1f0f64d23003a19a07d6b9638542130f6641d. buildroot has dropped this directory a long time ago. In OpenWrt the directory is still created by the PrepareStaging macro and is part of the default TARGET_CPPFLAGS. But nothing at all installs headers into this directory, nor should anything be installed under this path. Removing this directory from TARGET_CPPFLAGS will cut down the log noise a bit. Not only will CPPFLAGS be shorter, there will be less warnings set off by "-Wmissing-include-dirs" (or even failures when paired with "-Werror"). After all the directory does not even _exist_ in the SDKs, which are used on the build bots when building packages (see [1] and [2]). make[8]: Entering directory '/builder/shared-workdir/build/sdk/build_dir/target-aarch64_generic_musl/libmbim-1.20.0/src/common' CC libmbim_common_la-mbim-common.lo cc1: error: /builder/shared-workdir/build/sdk/staging_dir/target-aarch64_generic_musl/include: No such file or directory [-Werror=missing-include-dirs] cc1: all warnings being treated as errors [1] https://github.com/openwrt/packages/issues/10377 [2] https://github.com/openwrt/packages/pull/10378 Signed-off-by: Sebastian Kemper <sebastian_ml@gmx.net> Acked-by: Jo-Philipp Wich <jo@mein.io> Acked-by: Rosen Penev <rosenp@gmail.com>

* rules.mk: drop `include_mk` build ruleAlexandru Ardelean2018-01-261-4/+0
| | | | | | | | | | | | | | | | | The only users of this were the python packages from the `packages` feed. The 2 python interpreters would export some mk files (e.g. python-package.mk) and then other python packages would include it via this rule. But there's a few things wrong with this approach, most of them drawing from the fact that python host needs to be built first, to export these mk files. By now all uses of include_mk have been corrected in the feeds and this can be removed. Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>

* build: Pass -iremap gcc option as a single argumentMichal Sojka2017-02-091-1/+1
| | | | | | | | | | | | | | | Passing -iremap argument separately causes problems with projects that use scons and its ParseFlags function. Consider this SConscript example: env = Environment() d = env.ParseFlags("-iremap one:two") ParseFlags will interpret one:two as a file name and the returned dict d will contain only "-iremap". When the -iremap is passed to the compiler without an argument, compilation obviously fails. Signed-off-by: Michal Sojka <sojkam1@fel.cvut.cz>

| | | | | | | | | | | | | | | Add a new "checksum" make target which generates an sha256sums file over the image files produced in bin/targets/ and automatically call it during make world after the package index generation. The advantage of this new target is that it is guaranteed to run after the images, the SDK and the ImageBuilder archives have been generated to ensure that they all end up in the checksum file.

* build: Allow kernel modules to set build ID debug symbolFelix Fietkau2015-10-301-1/+2
| | | | | | | | | | | | | | | | | | | | This change adds support for specifying a build ID for kernel modules. This is done by setting PKG_BUILD_ID to a hexadecimal string, which will then be passed to the kernel linker. In addition, when this flag is set, the build ID debug symbol (.note.gnu.build-id) will not be stripped from the kernel module. This symbol is exported in sysfs by the kernel (if the kernel is compiled with CONFIG_KALLSYMS) and so can be used to uniquely identify a version of a kernel module in a running kernel. This is useful for keeping track of different versions of a module when doing experiments and development. Modules that specify the build ID will be ~100 bytes larger (depending on the length of the build ID specified). There is no size difference for kernel modules that do not set this variable.
