我想运行需要提升库的代码。我使用 CMake 构建了它。其他人已经编写了此代码和 cmakelist。它需要与 boost 正则表达式、文件系统和系统库链接。
我下载了 boost 1.48 并构建了上面提到的 3 个库。现在我有 dll 和静态库（.a）。我运行了一个使用这些库的简单程序。它工作得很好。
现在在使用 CMake 时，它给出了与 boost 库相关的链接器错误。我检查了cmakelist，但我不明白要修改什么。cmakelist 的相关部分是：
set(WITH_BOOST_REGEX ON CACHE BOOL "Include BOOST REGEX support")
set(WITH_BOOST_FILESYSTEM ON CACHE BOOL "Include BOOST FILESYSTEM support")
set(WITH_BOOST_SYSTEM ON CACHE BOOL "Include BOOST SYSTEM support")
if(WITH_BOOST_REGEX)
CHECK_MODULE(libboost-regex HAVE_BOOST_REGEX)
else()
set(HAVE_BOOST_REGEX FALSE)
endif()
if(WITH_BOOST_FILESYSTEM)
CHECK_MODULE(libboost-filesystem HAVE_BOOST_FILESYSTEM)
else()
set(HAVE_BOOST_FILESYSTEM FALSE)
endif()
我认为我只是在指定链接路径时犯了一个错误，但我无法找到如何更正它。
通过成功指定该程序和库的目标文件的路径，我成功地运行了一个与 boost_regex 的动态和静态库链接的简单示例程序。
现在在这段代码中，还有各种其他模块。它说 boost_regex 库丢失。link.txt 在那里说明要链接到哪些库，如下所示：
/usr/bin/c++ CMakeFiles/test_ensembletraining.dir/ensembletraining.o -o ../../bin/test_ensembletraining -rdynamic ../../lib/libensembletraining.so.0.3.2 ../../lib/libutils.so.0.3.2 ../../lib/libfeatureextraction.so.0.3.2 ../../lib/libintegraltransform.so.0.3.2 -lboost_regex.so -lboost_filesystem -lboost_system.so -lopencv_core -lopencv_flann -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_objdetect -lopencv_features2d -lopencv_calib3d -lopencv_legacy -lopencv_contrib -Wl,-rpath,/home/rizwan/vosm-0.3.3/lib:
它成功链接到 opencv 库，但没有链接到 boost 库。我认为指定链接库的路径有误。我试图通过浏览所有 cmakelist 文件来查找指定此路径的位置。
如果有人想提供帮助，请先从 VOSM 下载代码。使用 CMake 构建它。从 boost 网站下载 boost 1.48 库。如果它有效，请告诉我你是如何做到的。
这是 cmakecachelist 的一部分：
//Include BOOST FILESYSTEM support
WITH_BOOST_FILESYSTEM:BOOL=ON
//Include BOOST REGEX support
WITH_BOOST_REGEX:BOOL=ON
//Include BOOST SYSTEM support
WITH_BOOST_SYSTEM:BOOL=ON
//Include OPENCV 2.x support
WITH_OPENCV:BOOL=ON
这是cmakelist ..
