* rules.mk: export TMPDIRJo-Philipp Wich2017-12-121-0/+1
| | | | | | | | Set TMPDIR to the same value as the existing TMP_DIR variable in order to let gcc and various other utilities use the local temporary directory instead of the system-wide one. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* rules.mk: make PKG_CONFIG_DEPENDS properly track string valuesMatthias Schiffer2017-02-271-1/+1
| | | | | | | | | The confvar macro is adjusted to not only consider if a variable has a value or not, but also the value itself. Instead of creating a string of 'y' and 'n' characters, all variable names and values are concatenated and hashed. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
* 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>

* build: Suffix build directory with _$(LIBC) for external toolchainsFlorian Fainelli2017-01-291-1/+2
| | | | | | | | For external toolchain, we also know the type of C library used, and the toolchain triplet may not always be reflective of that, therefore make $(TARGET_DIR_NAME) suffixed with _$(LIBC). Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
* build: introduce STAGING_DIR_IMAGEJo-Philipp Wich2017-01-271-0/+1
| | | | | | | | | | | 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.

| | | | | | | | | | | | | directory for all targets Using a single host package staging dir (and build dir) significantly speeds up builds when multiple targets are built in succession, especially for large host packages like NodeJS. $(STAGING_DIR)/host is kept in addition to $(STAGING_DIR_HOSTPKG) in most places; it is still used as destination for host files in Build/InstallDev.

* build: add defaults for PKG_SOURCE, PKG_SOURCE_SUBDIR, PKG_VERSIONFelix Fietkau2016-12-221-0/+2
| | | | | | | | This makes it easier to unify versioning of git based package downloads. PKG_SOURCE_DATE along with an 8-character abbreviation of the git hash is used as PKG_VERSION, PKG_RELEASE should be used like normal packages. Signed-off-by: Felix Fietkau <nbd@nbd.name>
* build: implement make check and make package/X/checkFelix Fietkau2016-12-171-0/+8
| | | | | | | | | | | | | | | | This is intended to be used for a wide array of package sanity checks. The first check that is implemented is for the hash of downloaded files. It checks: - Missing hash - Use of SHA256 instead of MD5 - dl/<file> hash not matching hash in makefile - deprecated MD5SUM variable The deprecated MD5SUM variable check is skipped for feeds/ until OpenWrt is updated as well Signed-off-by: Felix Fietkau <nbd@nbd.name>
* rules.mk: add STAGING_DIR_HOSTPKG variableJo-Philipp Wich2016-11-011-0/+1
| | | | | | | Add a STAGING_DIR_HOSTPKG variable which refers to $(STAGING_DIR)/host in order to prepare support for relocating that directory in the future. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* build: add checksum targetJo-Philipp Wich2016-08-011-0/+7
| | | | | | | | | | | | | | | 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. Fixes FS#51. Uses sed to postprocess the OpenSSL digest output into an sha256sum command compatible format. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
* rules.mk: introduce new variable OUTPUT_DIRJo-Philipp Wich2016-04-061-1/+4
| | | | | | | | | | | Introduce a new variable OUTPUT_DIR which refers to the parent bin/ directory without the architecture specific component. Also construct the BIN_DIR variable based on OUTPUT_DIR now and add both target and subtarget components to it to prevent different subtargets from overwriting each others files in bin/.

* 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.

* build: use gcc-provided ar, nm and ranlib where appropriateFelix Fietkau2014-12-271-5/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since GCC 4.7, GCC provides its own wrappers around ar, nm and ranlib, which should be used for builds with link-time optimization. Since GCC 4.9, using them actually necessary for LTO builds using convenience libraries to succeed. There are some packages which try to automatically detect if gcc-{ar,nm,ranlib} exist (one example is my package "fastd" in the package repository, which tries to use LTO). This breaks because the OpenWrt build system explicitly sets the binutils versions of these tools. As it doesn't cause any issues to use gcc-{ar,nm,ranlib} instead of {ar,nm,ranlib} even without LTO, this patch just makes OpenWrt use the GCC-provided versions by default, which fixes the build of such packages with GCC 4.9. (I know that builds fail though when clang is used with -flto and gcc-{ar,nm,ranlib}, but as all OpenWrt toolchains are based on GCC, this isn't a real issue.) Completely cleaning the tree (or at least `make clean toolchain/clean`) is necessary to get a consistent state after the binutils plugins support patch and this one (as trying to use gcc-{ar,nm,ranlib} with a binutils built without plugin support will definitely lead to a build failure).
