我无法从 flandmark v0.7 Plataform x86 Win 7 生成 dll答案

【问题标题】：I Can't generate dll from flandmark v0.7 Plataform x86 Win 7我无法从 flandmark v0.7 Plataform x86 Win 7 生成 dll

【问题描述】：

我正在尝试编译我的 flandmark，但它非常复杂。 C:\flandmark\libflandmark\CMakeLists.txt 我放在第一行：

set(OpenCV "C:/opencv248/sources/cmake")

对吗？

关注我的完整文件 CMakeList.txt：

set(OpenCV "C:/opencv248/sources/cmake")
find_package( OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})

add_library(flandmark_static STATIC flandmark_detector.cpp flandmark_detector.h liblbp.cpp liblbp.h)
target_link_libraries(flandmark_static ${OpenCV_LIBS})
if(CMAKE_COMPILER_IS_GNUCC)
    set_target_properties(flandmark_static PROPERTIES COMPILE_FLAGS -fPIC)
endif(CMAKE_COMPILER_IS_GNUCC)
set_property(TARGET flandmark_static PROPERTY COMPILE_DEFINITIONS FLANDMARK_STATIC)

add_library(flandmark_shared SHARED flandmark_detector.cpp flandmark_detector.h liblbp.cpp liblbp.h)
target_link_libraries(flandmark_shared ${OpenCV_LIBS})

#setup Config.cmake
SET(FLANDMARK_BASE_DIR "${PROJECT_SOURCE_DIR}/libflandmark")
set(FLANDMARK_BINARY_DIR "${PROJECT_BINARY_DIR}/libflandmark")
configure_file(flandmarkConfig.cmake.in
  "${PROJECT_BINARY_DIR}/libflandmark/flandmarkConfig.cmake" @ONLY)

export(PACKAGE flandmark)

查看我通过 CMake-gui 执行时的结果：

OpenCV ARCH: x86
OpenCV RUNTIME: mingw
OpenCV STATIC: OFF
CMake Warning at C:/opencv248/build/OpenCVConfig.cmake:161 (message):
  Found OpenCV Windows Pack but it has not binaries compatible with your
  configuration.

  You should manually point CMake variable OpenCV_DIR to your build of OpenCV
  library.
Call Stack (most recent call first):
  libflandmark/CMakeLists.txt:2 (find_package)


CMake Error at libflandmark/CMakeLists.txt:2 (find_package):
  Found package configuration file:

    C:/opencv248/build/OpenCVConfig.cmake

  but it set OpenCV_FOUND to FALSE so package "OpenCV" is considered to be
  NOT FOUND.

拜托，你能详细告诉我我必须做什么吗？我不知道他们为什么不提供已经为我们编译的 .dll！ :(

谢谢

【问题讨论】：

实际上，如果您已经运行了 opencv，您可以通过将 libflandmark 中的文件添加到您的项目来快捷方式（从而跳过整个 dll/cmake 问题
感谢回复，但我的问题是：我的应用程序是 JAVA，我使用了 java wrapper (javacv) + opencv（工作正常），但我需要生成 .dll 来集成 JAVA + dll。

标签： c++ opencv cmake mingw feature-detection

【解决方案1】：

您只需将 cmake-gui 中的 OpenCV_DIR 变量设置为 OpenCV 的构建目录即可。然后它应该可以正常工作。

【讨论】：

感谢尿酸！！但是你能指定我把这个 OPENCV_DIR 放在什么文件上吗？将是：将(OpenCV_DIR "C:\opencv248\build\x86\vc10\lib") 设置为 libflandmark\CMakeLists.txt ?
我需要放置什么特定路径？你是说特指这条路吗？ OPENCV_DIR: C:/opencv248/build/x86/vc12/staticlib

【解决方案2】：

大家好，感谢您在这一步中帮助我。我已经解决了这个问题我遵循了 Uricamic 的指导，让我关注解决方案的详细信息：

在 cmake-gui 中设置变量 OPENCV_DIR = C:/opencv/build/x86/vc12/staticlib 我选择在哪里构建二进制文件：c:/flandmark-bin 然后通过Cmake-gui生成，生成的结果：

C:\flandmark-bin
  - CMakeCache.txt
  - CMakeFiles
  - examples
  - libflandmark
  - matlab_toolbox
C:\flandmark-bin\CMakeFiles
   - cmake.check_cache
   - CMakeGNUtoMS_lib.bat
   - CMakeOutput.log
   - CMakeTmp

   - CMakeCCompiler.cmake
   - CMakeCXXCompiler.cmake
   - CMakeDetermineCompilerABI_C.bin

   - CompilerIdCXX

   - CMakeCXXCompilerId.cpp

   - CMakeFiles
   - face.jpg
   - flandmark_model.dat
   - groupphoto.jpg
   - haarcascade_frontalface_alt.xml
   - seq_bruges04_300frames.avi
C:\flandmark-bin\examples\CMakeFiles
C:\flandmark-bin\libflandmark
  - CMakeFiles
  - flandmarkConfig.cmake
C:\flandmark-bin\libflandmark\CMakeFiles
C:\flandmark-bin\matlab_toolbox
   - mex
   C:\flandmark-bin\matlab_toolbox\mex
     - CMakeFiles

这个疑问解决了！

我的另一个疑问是如何从 C:/flandmark-bin 生成（上图）开始生成 .dll 文件？
