package/flann: fix build with cmake >= 3.11

2018-04-27T20:46:23+00:00

CMake < 3.11 doesn't support add_library() without any source file (i.e add_library(foo SHARED)). But flann CMake use a trick that use an empty string "" as source list (i.e add_library(foo SHARED "")). This look like a bug in CMake < 3.11. With CMake >= 3.11, the new behaviour of add_library() break the existing flann CMake code. >From CMake Changelog [1]: "add_library() and add_executable() commands can now be called without any sources and will not complain as long as sources are added later via the target_sources() command." Note: flann CMake code doesn't use target_sources() since no source file are provided intentionally since the flann shared library is created by linking with the flann_cpp_s static library with this line: target_link_libraries(flann_cpp -Wl,-whole-archive flann_cpp_s -Wl,-no-whole-archive) If you try to use "add_library(flann_cpp SHARED ${CPP_SOURCES})" (as it should be normally done), the link fail due to already defined symbol. They are building the shared version using the static library "to speedup the build time" [3] This issue is already reported upstream [2] with a proposed solution.

The HDF5 package is used by flann for testing purpose only and is not part of buildroot packages. However, if present in the host, it will be used and trigger the unsafe header/library path used in cross-compilation error. Signed-off-by: Johan Oudinet Signed-off-by: Thomas Petazzoni

See the conclusion about external toolchains during the Buildroot meeting [1]: "In the future, we stick to a single external toolchain version.

Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS

2014-12-11T21:48:13+00:00

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.
