Subject: [PATCH] src/cpp: fix cmake >= 3.11 build
|
|
|
|
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.
