qca how to generate dll's needed for project

ketjow

I need generate dll's for my project to use Qt Cryptographic Architecture, I try to go step by step as this short tutorial says. So I started with adding cmake to qt.

Then downloaded qca from git://anongit.kde.org/qca.git, cause this svn in the post was outdated. After that I took extra-cmake-modules from git://anongit.kde.org/extra-cmake-modules .

Now is time for compile it, I opened in qt cmakelist.txt from extra-cmake-modules , the CmakeWizard appears and I choose the MinGw Generator without any parameters.

The output looks like this:

-- 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 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Looking for Sphinx Documentation Builder... -- 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

In next step i opened the qca in qt. The CMake wizard appeard one more time and as tutorial said I added this argument:

-DECM_MODULE_PATH=G:\qca_new\extra_cmake_m-build

The output looks as follows:

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

And after that I'm stuck. I try to build project qca but I get the errors

...\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));

I searched for it and I found that somebody already created ticket connected with this issue. When this path didn't give me needed result, I went other way.

I commented some code in virtual method to avoid error during bulding.
Right now I can build 3 dll's:

libqca-qt5,
libqca-logger,
libqca-gnupg,
and when qt tries to build libqca-ossl.dll the error apears:

C:/Program Files/OpenVPN/bin/ssleay32.dll: file not recognized: File format not recognized collect2.exe: error: ld returned 1 exit status plugins\qca-ossl\CMakeFiles\qca-ossl.dir\build.make:104: recipe for target 'lib/qca-qt5/crypto/libqca-ossl.dll' failed mingw32-make[2]: *** [lib/qca-qt5/crypto/libqca-ossl.dll] Error 1 CMakeFiles\Makefile2:395: recipe for target 'plugins/qca-ossl/CMakeFiles/qca-ossl.dir/all' failed mingw32-make[1]: *** [plugins/qca-ossl/CMakeFiles/qca-ossl.dir/all] Error 2 Makefile:137: recipe for target 'all' failed mingw32-make: *** [all] Error 2 15:17:12: The process "C:\Qt\Qt5.3.1\Tools\mingw482_32\bin\mingw32-make.exe" exited with code 2.

I'm curious why it goes to openVpn folder at all.

I tried with cmake-gui as well like in this tutorial.
My parameters are source code (this qca repo which I downloaded from git) and my path to folder where binaries should be build. Configure and generate clicked and this is the output.

Configuring done Generating done

After that I searched for any dll's but nothing appears, this both method generated build folders with content,but I don't know what to do to get all dll's and add it to project.

Tree of folder where build content appeared looks like this

I would be grateful for any help in solving this problem.

Hi,

One fast way to build QCA with your Qt version is to build QCA using Qt Creator, you'll have everything setup correctly.

If you want the features using OpenSSL you also need to install OpenSSL first.

Hope it helps
