General Remarks

Requirements

• CMake 2.8.10
• Qt 5.1
• OpenGL support >= 3.2 (3.1 or below might work in some cases - use cmake option OPTION_NO_OPENGL_320)
• XCode/QtCreator/gcc/mingw/VisualStudio/etc..
• Partial C++11 support (as provided by MSVC11: http://wiki.apache.org/stdcxx/C++0xCompilerSupport)

Disclaimer

• FOR ASSESSMENT WE BUILD YOUR SUBMISSION IN WINDOWS WITH MSVC11 ONLY!
• WE OFFICIALLY SUPPORT WINDOWS WITH MSVC11 ONLY!
• Still, if you have problems on other platforms please let us know. We are dedicated to provide a framework that is working on all common desktop platforms.

Build Instructions

Windows

General Requirements:

• install cmake from http://www.cmake.org/cmake/resources/software.html
• install qt5.1 from (for this exercise we used visual studio 2012 x64 and 2013 x64) http://qt-project.org/downloads
• install visual studio or qt creator

Windows - Visual Studio (the preferred way)

Prerequisites

• Having a Visual Studio installed (MSVC11 or UP)

Building and Running an Exercise

• Start cmake-gui with batch or manually (but provide QT_DIR and make sure the Qt binaries are on the path)
• Open CMakeLists.txt with cmake-gui
• Specify path to build binaries (recommended in extra build directory) -> "build" folder
• Press configure and generate
• Open solution with batch
• setup working directory of cg2sandbox to ".." for each configuration you want to run
• compile and run as required...

Windows - Qt Creator

Prerequisites

• Use the qt creator 2.4 or newer (at best, the one that comes with qt 5.1)
• Set the path for the CMake executable in Tools > Options > Build & Run > CMake.
• Now you should be able to open CMakeLists.txt files (if not check http://doc.qt.digia.com/qtcreator-2.4/creator-project-cmake.html)
• NOTE: you need a CDB if you want to compile with MSVC... http://msdn.microsoft.com/de-de/windows/hardware/hh852363
• Installing the Debugging Tools should suffice.

Building and Running an Exercise

• File > Open File or Project
• select the CMakeLists.txt
• specify Build Directory
• Press Run-CMake, then finish
• Specify Working Directory via Projects > Run > Working Directory (see http://doc.qt.digia.com/qtcreator-2.3/creator-run-settings.html) to point to exercise folder, not the build folder
• Compile (e.g. with [Ctrl] + [R])

Windows - NMake

Prerequisites

• Cmake is available via command line
• You habe nmake installed and you can use ae.g. Visual Studio Command Promt

Building and Running an Exercise

• set PATH=%PATH%;"C:\Qt\5.1.0\qtbase\bin"
• mkdir build
• cd build
• cmake -DCMAKE_PREFIX_PATH="C:\Qt\5.1.0\qtbase\lib\cmake" -G "NMake Makefiles" .. # this worked for us... (perhaps you need to specify platform/compiler...)
• nmake
• cd ..
• set QT_DIR=C:\Qt\5.1.0
• set PATH=%PATH%;%QT_DIR%\qtbase\bin;
• ./build/exercise1

Linux

Only tested on Ubuntu 13.04 x64.

Gathering Requirements

• install cmake, this should give you 2.8.10 or above (in Ubuntu 13.04)
  • sudo apt-get install cmake
• install a C++ compiler with support for C++11 (GCC 4.7 or higher is recommended)
  • e.g. for Ubuntu 12.04:
    • add-apt-repository -y ppa:george-edison55/gcc4.7-precise
    • apt-get -y install gcc-4.7 g++-4.7
• download qt 5.1.0 (http://qt-project.org/downloads)
• suppose the filename is qt.run (replace appropriately)
• in downloaded folder do:
  • chmod u+x qt.run
  • sudo ./qt.run

Building and Running an Exercise

in your cg2 exercise1 (or exercise#) source folder do:

• mkdir build
• cd build
• PATH="/opt/Qt5.1.0/5.1.0/gcc_64/bin;$PATH" cmake .. # this worked for us...
  • you might need to set the newer compiler manually: -DCMAKE_CXX_COMPILER=/usr/bin/gcc-4.7
• make
• cd ..
• ./build/exercise1

OS X

Building and Running an Exercise

• The following instructions are used for XCode. You can also use other IDEs like QtCreator or Netbeans.
• Start CMake.
• Choose generator, e.g., XCode or Unix Makefiles.
• Configure and Generate.
• Open XCode project and run make

Third Party Libraries

In order to make the libraries compile with our compiler setup, the following modifications had to be made:

The following modifications where made in order to get things running. Note: these are not modifications you need to do when using this repo.

Assimp Modifications

assimp/CMakeLists.txt

• ENABLE_BOOST_WORKAROUND was set to ON by default
• disabled the uninstall capability

assimp/code/CMakeLists.txt

• COMPILE_FLAGS "-D_CRT_SECURE_NO_WARNINGS" was added to avoid secure warnings in msvc
• COMPILE_FLAGS "-D_SCL_SECURE_NO_WARNINGS" was added to avoid secure warnings in msvc

assimp/code/LWOAnimation.cpp

• #include was added in order to compile in windows

Qt 5.1.1 Compiling for Visual Studio 2013 RC

• http://qt-project.org/forums/viewthread/32508
• set CL=/MP
• set QMAKEPATH=C:/Qt/5.1.1.12/qtbase/bin
• configure -opensource -confirm-license -nomake examples -nomake tests -opengl desktop -platform win32-msvc2013
