Question

我需要为我的项目生成dll才能使用Qt Cryptographic Architecture，正如this简短的教程所说，我试着一步一步走。所以我开始将qmake添加到qt。

然后从qca下载git://anongit.kde.org/qca.git，导致该帖子中的svn过时。之后我从extra-cmake-modules获取了git://anongit.kde.org/extra-cmake-modules。

现在是编译它的时候了，我是从extra-cmake-modules的qt cmakelist.txt打开的，出现了CmakeWizard，我选择了没有任何参数的MinGw Generator。

输出如下：

    -- The C compiler identification is GNU 4.8.2
-- Check for working C compiler: C:/Qt/Qt5.3.1/Tools/mingw482_32/bin/gcc.exe
-- Check for working C compiler: C:/Qt/Qt5.3.1/Tools/mingw482_32/bin/gcc.exe -- works

-- Sphinx Documentation Builder not found - documentation will not be built (see http://sphinx-doc.org/)
-- Configuring done
-- Generating done
-- Build files have been written to: G:/qca_new/extra_cmake_m-build

在下一步中，我打开了qt中的qca。 CMake向导再次出现，正如教程所说我添加了这个论点：

-DECM_MODULE_PATH=G:\qca_new\extra_cmake_m-build

输出如下：

CMake Warning:
  Manually-specified variables were not used by the project:

之后我被困住了。我尝试构建项目qca但我得到了错误

...\qca\plugins\qca-ossl\qca-ossl.cpp:5808: error: 'SSL_SESSION_get_compress_id' was not declared in this scope
   sessInfo.isCompressed = (0 != SSL_SESSION_get_compress_id(ssl->session));

我搜索了它，发现有人已经创建ticket与此问题有关。当这条路径没有给我需要的结果时，我走了另一条路。

我也尝试过cmake-gui。我的参数是源代码（我从git下载的这个qca repo）和我应该构建二进制文件的文件夹的路径。配置并生成单击，这是输出。

在两个metod之后我搜索了任何dll但没有出现，这两种方法都生成了包含内容的构建文件夹，但我不知道如何获取dll并将其添加到项目中。

构建内容出现的文件夹树看起来像this

更新：我在虚拟方法中评论了一些代码，以避免在构建期间出错。现在我可以构建3个dll：

libqca-qt5，
libqca记录器，
libqca-gnupg的，当qt尝试构建libqca-ossl.dll时出现错误：

C：/ Program Files / OpenVPN / bin / ssleay32.dll：文件无法识别：文件
格式无法识别 collect2.exe：错误：ld返回1退出状态 plugins \ qca-ossl \ CMakeFiles \ qca-ossl.dir \ build.make：104：目标'lib / qca-qt5 / crypto / libqca-ossl.dll'的配方失败 mingw32-make 2： * [lib / qca-qt5 / crypto / libqca-ossl.dll]错误1 CMakeFiles \ Makefile2：395：目标'plugins / qca-ossl / CMakeFiles / qca-ossl.dir / all'的配方失败 mingw32-make 1：* [plugins / qca-ossl / CMakeFiles / qca-ossl.dir / all]错误2 Makefile：137：目标'all'的配方失败 mingw32-make：*** [全部]错误2 15:17:12：进程“C：\ Qt \ Qt5.3.1 \ Tools \ mingw482_32 \ bin \ mingw32-make.exe”退出，代码为2。

我很好奇为什么它会转到openVpn文件夹。

然后呢

如果对此问题有任何帮助，我将不胜感激。
