* build: disable automake dependency trackingMichael Pratt2023-03-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of Automake have changed dependency tracking significantly (reference commit below) causing breakage in some package builds when using newer Automake with packages that need autoreconf that were bootstrapped with an old version of Automake. Those changes cause a great inconsistency between packages over time where some packages may or may not use this feature, and may or may not update the .ac and .am files to work with the new methods. This problem might exist in many packages where autoreconf is not currently required, but would cause build failure if autoreconf is used. Fortunately, this feature is practically useless for the purposes of Openwrt and the average developer, so we can disable it. GNU Automake manual states in part: "Because dependencies are only computed as a side-effect of compilation... no dependency information exists the first time a package is built... dependency tracking is completely useless for one-time builds..." A nice side-effect is that build times are slightly faster. Ref: 6a675ef17edf7109da189f5ae70e2dc6b7665896 (automake.git) Signed-off-by: Michael Pratt <mcpratt@pm.me>
* build: skip download for host build with AUTOREMOVE if already compiledChristian Marangi2023-01-231-1/+5
| | | | | | | | | | | | | | | | | | | | | | Packages in general use 4 check to trigger a recompile: - timestamp for the build_dir - timestamp for the staging stamp dir - depends hash for the build_dir prepared file - presence of package archieve in dl If host tools are prebuilt and shipped in a container or manually installed from an archieve, it would be ideal to skip including the package archieve and just provide the build_dir prepared files and the staging stamp file (and the actualy prebuilt tools). Add some logic to skip dl download for host tools if AUTOREMOVE is selected and checks for the presence of staging dir stamp file and build dir stamp file. If one of these requirements are not met, the package is redownloaded and rebuilt. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
* build: make find_md5 reproducible with AUTOREMOVEChristian Marangi2022-09-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | While experimenting with the AUTOREMOVE option in search of a way to use prebuilt host tools in different buildroot, it was discovered that the md5 generated by find_md5 in depends.mk is not reproducible. Currently the hash is generated by the path of the file in addition to the file mod time. Out of confusion, probably, there was an idea that such command was used on the package build_dir. Reality is that this command is run on the package files. (Makefile, patches, src) This is problematic because the package Makefile (for example) change at each git clone and base the hash on the Makefile mtime doesn't really reflect if the Makefile actually changes across a buildroot or not. A better approach is to generate an hash of each file and then generate an hash on the sort hash list. This way we remove the problem of git clone setting a wrong mtime while keeping the integrity of checking if a file changed for the package as any change will result in a different hash. Introduce a new kind of find_md5 function, find_md5_reproducible that apply this new logic and limit it only with AUTOREMOVE option set to prevent any kind of slowdown due to additional hash generation.

* build: handle directory with whitespace in AUTOREMOVE cleanChristian Marangi2022-09-111-2/+2
| | | | | | | | | Package with whitespace in their build directory are not correctly removed when CONFIG_AUTOREMOVE is enabled. This is caused by xargs that use whitespace as delimiters. To handle this use \0 as the delimiter and set find to use \0 as the delimiter. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

* download: improve handling of invalid local filesEneas U de Queiroz2021-11-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 4e19cbc5533: [download: handle possibly invalid local tarballs] added a FORCE rule to downloaded files, so that they will be always checked by download.pl. As a side-effect, check-compile will fail, forcing unnecessary package rebuilds. The check-compile.txt log shows (for libxml2 for example): Considering target file '.../dl/libxml2-2.9.12.tar.gz'. ... prerequisite 'FORCE' of target '.../dl/libxml2-2.9.12.tar.gz' does not exist. Must remake target '.../dl/libxml2-2.9.12.tar.gz'. ... Giving up on target file '...libxml2-2.9.12/.prepared_...'. Giving up on target file '...libxml2-2.9.12/.configured_...'. Giving up on target file '...libxml2-2.9.12/.built'. Giving up on target file '...stamp/.libxml2_installed'. Giving up on target file '.compile'. Then the package is rebuilt even if it is not otherwise needed. To fix this, instead of always forcing the download target to be remade, check its hash first: if it matches, then the FORCE is not added. Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com>

* download: handle possibly invalid local tarballsPetr Štetiar2020-11-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it's assumed, that already downloaded tarballs are always fine, so no checksum checking is performed and the tarball is used even if it might be corrupted. From now on, we're going to always check the downloaded tarballs before considering them valid. Steps to reproduce: 1. Remove cached tarball rm dl/libubox-2020-08-06-9e52171d.tar.xz 2. Download valid tarball again make package/libubox/download 3. Invalidate the tarball sed -i 's/PKG_MIRROR_HASH:=../PKG_MIRROR_HASH:=ff/' package/libs/libubox/Makefile 4. Now compile with corrupt tarball source make package/libubox/{clean,compile} Signed-off-by: Petr Štetiar <ynezz@true.cz>
* build: improve ccache supportRoman Yeryomin2020-07-111-1/+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.

* build: fix HOST_CONFIGURE_VARS placementJo-Philipp Wich2017-01-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Instead of passing HOST_CONFIGURE_VARS as arguments to the configure script, pass it as environment variables which brings the logic in line with the behaviour of package-defaults.mk. The change is needed since passing environment variables as configure parameters only works with GNU autoconf which evaluates command line arguments looking like variable assignments. Doing the same with non-autoconf configure scripts is not guaranteed to work since such scripts might terminate due to unknown argument errors. One example case is the cmake configure script which bails out when called as "./configure LDFLAGS=..." but not when called as "LDFLAGS=... ./configure". Also change the SHELL override to CONFIG_SHELL in the default HOST_CONFIGURE_VARS as the former is not properly propagated through the various GNU configure invocations since it gets lost when configure re- executes itself. A prior attempt to change the variable placement had to be reverted due to the missing SHELL -> CONFIG_SHELL change, leading to misgenerated libtool executables in various packages.

* build: copy contents of 'src' folder to build dirs (if present)Alexandru Ardelean2016-10-151-0/+1
| | | | | | | | | | | | | | | | | | | | | The normal Prepare step for a build is unpack, apply patches. But for certain packages, patches contain whole files, which would be nice to have separately and copied over as a last step in the Prepare phase. We need it for some other packages + patches, but I think the 'hostapd' package can be used as a test for this. As a quick note: the reason the condition is being evaluated as `[ ! -d ./src/ ] || $(CP) ./src/* $(HOST_BUILD_DIR)` and not with `[ -d ./src/ ] && $(CP) ./src/* $(HOST_BUILD_DIR)` is that the latter would translate in a build failure if the `src` folder is not present (the exit code would be 1). The first one, succeeds for both cases (if `src` present or not). Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com>

| | | | | | | | | | | | | | | | | | Make usually passes -j and jobserver arguments as part of MAKEFLAGS. LEDE removes MAKEFLAGS to have better control of the build, and re-adds the jobserver arguments with -j to the Make commandline where desired. Make 4.2+ behave differently with these arguments passed on the commandline than in MAKEFLAGS: -j will override the jobserver argument and the job count will be unlimited. Moving the flags to MAKEFLAGS will need many packages to be changed and tested; therefore, we opt for a less invasive change for now and just remove -j for Make 4.2+, as the jobserver argument alone is enough to enable parallel builds for these Make versions.
