Howtos - Hack on Windows 7, 8 and 10¶

You need to:

1. Install Git for Windows (needed by Tortoise Git) : https://gitforwindows.org/.
   1. Do not install in "Program files" or in a path which contains spaces. We recommend to install in C:\git.
2. Install Tortoise Git : http://code.google.com/p/tortoisegit/.
3. Install Qt and Qt Creator from https://www.qt.io/download-qt-installer
4. Install the latest version of MinGW from http://sourceforge.net/projects/mingw/files/Installer/mingw-get-setup.exe/download. GCC version 4.6.x or superior is required.
5. Add <path to mingw>\mingw\bin;<path to qt>\bin to your path environment variable.
6. Optional: It's now possible to recompile all Qt, see the section Custom Qt compilation below.
7. Install proto buff library source
   1. Download and uncompress the following file : https://github.com/google/protobuf/releases/download/v2.6.1/protobuf-2.6.1.tar.gz
   2. Rename the directory to protbuf
   3. Launch "Git Bash" and go to /c/protobuf then type :
      1. export MAKE=mingw32-make
      2. ./configure CXXFLAGS=-O2 --enable-shared=no
      3. mingw32-make
   4. Add to your path these directories : C:\protobuf\src\;C:\protobuf\src\.libs to reach executable protoc and library libprotobuf.a.
8. Git clone the repository :
   1. git://github.com/Ummon/D-LAN.git if you just want clone the repository (read-only).
   2. git@github.com:Ummon/D-LAN.git if you have a full access (read+write).
9. Generate the C++ code from the Protocol Buffer files (only for version 1.1)
   1. Open a Bash command line, you can use the shortcut "Git Bash" installed with git
   2. Go to the directory "D-LAN/application"
   3. Run the shell script file 1.generate_protos_cpp to generate the .h and .cc files in the directory Protos.
10. Set up Qt Creator
    1. Launch Qt Creator
    2. Open the projects d-lan/application/GUI.pro and d-lan/application/Core.pro
    3. For both projects:
       1. Uncheck Shadow build in the Build Settings tab.
       2. Add the argument debug -f Makefile-Core to Make for the build configuration Debug and release -f Makefile-Core for the build configuration Release. Replace 'Core' by 'GUI' for the GUI project.
    4. Add -e as an argument and check¹ Run in terminal in the Run Settings tab of the Core project.
    5. You can now compile and run the two projects.

¹ Without this option the Core cannot be launched in debug mode (stderr cannot be used).

Custom Qt compilation¶

Goals¶

• Add the support of C++11, it can improve a bit the performances, see http://labs.qt.nokia.com/2011/05/26/cpp0x-in-qt/ for more information.
• Recompile Qt with a more recent version of GCC. Qt binaries are released compiled with GCC 4.4.
• Remove unused components and reduce the size of DLL files.

Steps¶

• Add QMAKE_CXXFLAGS += -std=gnu++0x at the end of the file mkspecs/win32-g++-4.6/qmake.conf

• Configure Qt with the following command
  

  ./configure.exe -ltcg -opensource -debug-and-release -platform win32-g++-4.6 -nomake demos -nomake examples -qt-style-windowsxp -qt-style-windowsvista -no-style-plastique -no-style-cleanlooks -no-style-motif -no-style-cde -no-qt3support -no-opengl -no-accessibility -no-native-gestures
  

• Then compile with the command mingw32-make
