dependencies/cmake: blacklist cmake 3.7

2017-02-28T08:40:27+00:00

cmake-3.7 has a bug in how it handles rpath, linking with libraries from the host. Until we completely understand the issue, just blacklist cmake-3.7. The issue has been reported upstream: http://public.kitware.com/pipermail/cmake/2017-February/064970.html Reported-by: Baruch Siach Signed-off-by: "Yann E.

package: add generic support for lz archives

2017-02-15T21:11:11+00:00

This commit teaches the generic package handling code how to extract .tar.lz archives. When lzip is not installed on the host, host-lzip gets built automatically. Signed-off-by: Baruch Siach Reviewed-by: Thomas De Schampheleire Signed-off-by: Thomas Petazzoni

package: refactor listing of extractor dependencies

2017-02-15T21:11:11+00:00

Don't special case $(XZCAT) when constructing DL_TOOLS_DEPENDENCIES. The next commit will introduce another extractor that automatically builds when not installed. Introduce EXTRACTOR_DEPENDENCY_PRECHECKED_EXTENSIONS that lists archive extensions for which the extractor is already checked in support/dependencies/check-host-foo.mk. Use this in the newly introduced extractor-dependency to populate DL_TOOLS_DEPENDENCIES.

core: do not reset DEPENDENCIES_HOST_PREREQ in dependencies.mk

support/dependencies: ensure we have 'file' on the host

2016-12-27T17:02:42+00:00

Recently, the autoconf macros for libtool started using '/usr/bin/file' to determine the type of library that is generated by the toolchain. Packages that use this recent version of the libtool autoconf macros will fail in a rather dramatic way when /usr/bin/file is not present on the host: the package will still build but no shared library is generated, which in turn may cause build failures in other packages that link with it. For example, libpng's configure determines that it is not possible to build a shared library on MIPS64 because the expected output from 'file' is not present. Therefore, only a static libpng.a is built. Later, bandwithd links with -lpng but it doesn't use the pkg-config's Private-Libs (because it's not linking statically) and it doesn't have access to the NEEDED reference from the shared library. Therefore, it doesn't link with zlib and fails with pngrutil.c:(.text+0x55c): undefined reference to `inflate' We cant use host-file because it is itself an autotools package and is itself using libtool, so this would be a chicken-n-egg problem. Besides, the libtool script really wants to call /usr/bin/file, so it would not even find our host-file anyway. So, just require that '/usr/bin/file' is present on the host. Signed-off-by: "Yann E.

support/dependencies: use the new kconfig option to check UTF8 locale

2016-12-04T14:38:16+00:00

Currently, we require a host with an UTF-8 locale as soone as we build a Buildroot toolchain with support for locales. This means that we do erquire such a locale when building a toolchain with either uClibc, glibc or musl. However, glibc and musl do not require such a locale to be present. Use the new option to check if an UTF8 locale is needed on the host, rather than deriving that from toolchain settings. Signed-off-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

core: don't build host-cmake if it is available on the build host

2016-09-17T14:12:06+00:00

Currently all cmake packages depend on host-cmake. Unfortunately host-cmake takes a long time to configure and build: almost 7 minutes on a dual-core i5 with SSD. The time does not change even with ccache enabled. Indeed, building host-cmake is avoidable if it is already installed on the build host: CMake is supposed to be quite portable, and the only patch in Buildroot for the CMake package seems to only affect target-cmake. Thus we automatically skip building host-cmake and use the one on the system if: - cmake is available on the system and - it is recent enough. First, we leverage the existing infrastructure in support/dependencies/dependencies.mk to find out whether there's a suitable cmake executable on the system. Its path can be passed in the BR2_CMAKE environment variable, otherwise it defaults to "cmake". If it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using our own cmake (the old behaviour). Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE) instead of $(HOST_DIR)/usr/bin/cmake. Unlike what we do for host-tar and host-xzcat, for host-cmake we do not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake would be a dependency for _any_ package when it's not installed on the host, even when no cmake package is selected. Cmake versions older than 3.0 are affected by the bug described and fixed in Buildroot in ef2c1970e4bf ("cmake: add patch to fix Qt mkspecs detection"). The bug was fixed in upstream CMake in version 3.0 [0]. Amongst all the cmake packages currently in Buildroot, the currently highest version mentioned in cmake_minimum_required() is 3.1 (grantlee and opencv3). Thus we use 3.1 as the lowest required cmake for now, until a package is bumped, or a new package added, with a higher required version.
