Question

我发现了android_cmake和boost的奇怪行为。我使用

开始使用cmake

cmake ../ -DCMAKE_TOOLCHAIN_FILE=/opt/android/android-cmake/android.toolchain.cmake -DBOOST_ROOT=/opt/android/android-cmake/common-libs/boost -DBOOST_INCLUDEDIR=/opt/android/android-cmake/common-libs/boost/boost-trunk/boost -DBOOST_LIBRARYDIR=/opt/android/android-cmake/common-libs/boost/libs/armeabi-v7a -DBoost_DEBUG=1

如您所见，设置了所有3个boost变量BOOST_ROOT，BOOST_INCLUDEDIR和BOOST_LIBRARYDIR。通过“find_host_package”函数找到提升。下面是输出的一部分：

-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:646 ]   BOOST_ROOT = /opt/android/android-cmake/common-libs/boost
-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:648 ]   BOOST_INCLUDEDIR = /opt/android/android-cmake/common-libs/boost/boost-trunk/boost
-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:650 ]   BOOST_LIBRARYDIR = /opt/android/android-cmake/common-libs/boost/libs/armeabi-v7a
-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:705 ] Include debugging info:
-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:707 ]   _boost_INCLUDE_SEARCH_DIRS = /opt/android/android-cmake/common-libs/boost/boost-trunk/boost;/opt/android/android-cmake/common-libs/boost/include;/opt/android/android-cmake/common-libs/boost;C:/boost/include;C:/boost;/boost/include;/boost;/sw/local/include
-- [ /opt/sw/cmake-2.8.10.2/share/cmake-2.8/Modules/FindBoost.cmake:734 ] location of version.hpp: /usr/local/include/boost/version.hpp

正如您所看到的，提升版本不是来自设置位置，而是来自

/usr/local/include/boost/version.hpp

即使我指定的位置包含version.hpp：

/opt/android/android-cmake/common-libs/boost/boost-trunk/boost/version.hpp

现在我无法确定发生了什么以及cmake在哪些方面取得了进展......有什么建议吗？

您可能需要强行排除默认搜索

Boost_NO_SYSTEM_PATHS - 设置为ON以禁用在位置搜索这些提示变量没有指定。默认为OFF。

尝试，

cmake ../ -DCMAKE_TOOLCHAIN_FILE=/opt/android/android-cmake/android.toolchain.cmake -DBOOST_ROOT=/opt/android/android-cmake/common-libs/boost -DBOOST_INCLUDEDIR=/opt/android/android-cmake/common-libs/boost/boost-trunk/boost -DBOOST_LIBRARYDIR=/opt/android/android-cmake/common-libs/boost/libs/armeabi-v7a -DBoost_DEBUG=1 -DBoost_NO_SYSTEM_PATHS=ON

android cmake发现提升包含错误
