使用 Cmake 构建 FLANN 失败

Question

我正在尝试构建 FLANN 库，以便之后构建 PCL 库。

使用 CMake 编译源代码时出现错误。 我想我错过了一些非常基本的东西。由于我找不到适合我的系统的编译库，因此我必须自己构建它。

使用命令

~/flann-1.8.4-src/build> cmake ..

我得到

CMake Error at src/cpp/CMakeLists.txt:86 (add_library):
No SOURCES given to target: flann
CMake Error at src/cpp/CMakeLists.txt:32 (add_library):
No SOURCES given to target: flann_cpp

SLES11 操作系统上的 flann 1.8.4 和 1.9.1 会发生这种情况。

有什么提示吗？

以下是cmake所说的完整转录：

In your flann dir 跑

touch src/cpp/empty.cpp

在 src/cpp/CMakeList 中.txt 取代

add_library(flann_cpp SHARED "") and add_library(flann SHARED "")

跟

add_library(flann_cpp SHARED empty.cpp) and add_library(flann SHARED empty.cpp)

希望这对:)有所帮助 链接，感谢齐瓦列夫的评论
