build: add support for PKG_SUBDIRS variable

2024-07-08T06:49:42Z

Add support for overriding the SUBDIRS variable while invoking Make by defining it after Make in the command line. This is useful for builds that have previously patched out the building of certain subdirectories in projects that use recursive and independent Makefiles, for example, to block the building of docs or test suites. The wildcard function is used in the case of there being subdirectories within any of the subdirectories, for example, in the building of gengetopt, in order to avoid the problem where Make will attempt to execute a Makefile in a subdirectory that does not exist within the subdirectory it is currently running from because it really exists at the top-level, or one that exists within one of the subdirectories when ran from top-level. There are also cases where the Makefiles in the subdirectories have the recursive building rules even though there are no more subdirectories beyond that point, for example, with gnulib.

build: add APK package build capabilities

2024-05-17T20:21:26Z

A new option called `USE_APK` is added which generated APK packages (.apk) instead of OPKG packages (.ipk). Some features like fstools `snapshot` command are not yet ported Signed-off-by: Paul Spooren

build: add support to use the mold linker for packages

2023-07-04T18:25:41Z

If CONFIG_USE_MOLD is set, all target packages will use the mold linker. Except the ones which opted-out via setting PKG_BUILD_FLAGS:=no-mold. Signed-off-by: Andre Heider

treewide: opt-out of tree-wide mold usage

2023-07-04T18:25:41Z

These use linker scripts, which mold doesn't support. Signed-off-by: Andre Heider

build: export GIT_CEILING_DIRECTORIES for package builds

2023-05-31T17:33:00Z

A package may run git as part of its build process, and if the package source code is not from a git checkout, then git may traverse up the directory tree to find buildroot's repository directory (.git). For instance, Poetry Core, a Python build backend, will read the contents of .gitignore for paths to exclude when creating a Python package. If it finds buildroot's .gitignore file, then Poetry Core will exclude all of the package's files[1]. This exports GIT_CEILING_DIRECTORIES for both package and host builds so that git will not traverse beyond $(BUILD_DIR)/$(BUILD_DIR_HOST).

build: remove backwards compatibility for PKG_USE_MIPS16

2023-05-12T11:06:14Z

All package feeds have been refactored to PKG_BUILD_FLAGS:=no-mips16. Signed-off-by: Andre Heider

build: add a config knob to enable LTO for all packages

2023-03-21T17:28:24Z

This enables LTO for all packages which haven't opted-out. Signed-off-by: Andre Heider

build: add a config knob to enable gc-sections for all packages

2023-03-21T17:28:23Z

This enables the linker's garbage collection for all packages which haven't opted-out. Signed-off-by: Andre Heider

treewide: add support for "lto" in PKG_BUILD_FLAGS

2023-03-21T17:28:22Z

This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-lto". Some packages used LTO, but not the linker plugin. This unifies 'em all to attempt to produce better code. Quoting man gcc(1): "This improves the quality of optimization by exposing more code to the link-time optimizer." Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed that every buildsystem uses +$(MAKE) correctly. Signed-off-by: Andre Heider

treewide: add support for "gc-sections" in PKG_BUILD_FLAGS

2023-03-21T17:28:22Z

This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-gc-sections". Note: libnl, mbedtls and opkg only used the CFLAGS part without the LDFLAGS counterpart. That doesn't help at all if the goal is to produce smaller binaries. I consider that an accident, and this fixes it. Note: there are also packages using only the LDFLAGS part. I didn't touch those, as gc might have been disabled via CFLAGS intentionally.
