Compiling Godot with SCons - scons

Today I want to build the open source godot project (http://www.godotengine.org/wp/) on Windows 7. I give attention to the compiling instructions (http://www.godotengine.org/wiki/doku.php?id=compiling_windows) but when I use SCons in the command line, I get this:
fatal error LNK1112: module machine type 'x86' conflicts with target machine type 'X64'
This problem is already described here:
[linking problem: fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86' (linking problem: fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'X86')
But I have another question.
I know, I have to define the architecture type of environment variable in SConstruct file (I can post it here, if you want). Unfortunately it doesn't work as thought.
At first I edited the line, where the environment variable is initialized:
env_base=Environment(tools=custom_tools,ENV = {'PATH' : os.environ['PATH']},TARGET_ARCH='x86');
I only added TARGET_ARCH='x86'. Is that wrong or should I set the target arch someplace else? The LNK 1112 error still occurs.
It would be great, if somebody could me help. :)

There is nothing to change in SConstruct, but the right compiler version is needed. So go to the directory C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\Tools\Shortcuts and call the VS2013 x86 Native Tools command line. Then it works. :)

Missing variable FLTK_FLUID_EXECUTABLE

While compiling ITKSNAP using ITK,VTK and FLTK on my computer(Windows 7 and Microsft visual studio 2012) shows following error:
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
FLTK_FLUID_EXECUTABLE
CMake Error at CMakeLists.txt:570 (ITK_DISABLE_FLTK_GENERATED_WARNINGS):
Unknown CMake command "ITK_DISABLE_FLTK_GENERATED_WARNINGS".
I don't know how to link fluid executable.
Please suggest some solution.

Audacity installation error

Getting following error on installing audacity in linux:
export/ExportPCM.cpp: In member function ‘bool ExportPCM::AddStrings(AudacityProject*, SNDFILE*, Tags*, int)’:
export/ExportPCM.cpp:740: error: ‘SF_STR_GENRE’ was not declared in this scope
export/ExportPCM.cpp:764: error: ‘SF_STR_TRACKNUMBER’ was not declared in this scope
make[1]: *** [export/ExportPCM.o] Error 1
make[1]: Leaving directory `/root/audacity/audacity-src-2.0.5/src'
make: *** [audacity] Error 2
Can any one help me in fixing the issue?
I also got the same error. The following is my solution:
From the first error line:
export/ExportPCM.cpp: In member function ‘bool ExportPCM::AddStrings(AudacityProject*, SNDFILE*, Tags*, int)’:
we see that it is caused by libsndfile. Therefore, you just need to compile the latest libsndfile. Download tarball here http://www.mega-nerd.com/libsndfile/#Download
After that, you compile audacity again and compilation will be successful.
This is an error when compiling that package, not during installation. It most likely is the result of some version incompatibility between the code you try to compile and some development version installed on your system which is referred to by the code. You will have to find out what packages usually declare those constants and adjust your versions accordingly.
Apart from that: sure you want to make such a "wild" installation? Typically packages are installed using your systems software management system these days. That is much easier, more robust and allows easy upgrades to newer versions. Audacity should be available for most GNU/Linux distributions.

OpenNI 2 and Visual Studio 2012

I just downloaded OpenNI 2 SDK (www.openni.org) and I am trying to setup a project in Visual Studio 2012.
What I did:
Create a new C++ Win32 Console Application Project
Go to Project>MyProject Properties and, in Configuration Properties>VC++ Directories...
Added C:\Program Files (x86)\OpenNI2\Redist\; to Executable Directories
Added C:\Program Files (x86)\OpenNI2\Include\; to Include Directories
Added C:\Program Files (x86)\OpenNI2\Redist\; to Reference Directories
Added C:\Program Files (x86)\OpenNI2\Lib\; to Library Directories
But when I try to build I have the following unresolved symbol error (where ConsoleApplication1 is my project's name)
Error 1 error LNK2019: unresolved external symbol
__imp__oniInitialize referenced in function
"public: static enum openni::Status __cdecl openni::OpenNI::initialize(void)"
(?initialize#OpenNI#openni##SA?AW4Status#2#XZ)

ConsoleApplication1
I know this linking error is saying that the linker can't find some libraries but I thought what I just did was enough.
I also tried the 64 bit version, creating a 64 bit project, but I have the same errors.
I couldn't find satisfying documentation on this topic.
I'm sure I'm missing something silly. Can you please give some advice on this?
Also you should do the below steps:
0-In the C/C++ section, under the "General" node, select
"Additional Include Directories"
and add
"$(OPENNI2_INCLUDE)" (if you use the 32-bit version) or
"$(OPENNI2_INCLUDE64)" (if you use the 64-bit version).
These are environment variables that point to the location of the OpenNI Include directory. (The defaults are :
C:\Program Files\OpenNI2\Include or
C:\Program Files (x86)\OpenNI2\Include)
1-In the Linker section, under the "General" node, select
"Additional Library Directories"
and add
"$(OPENNI2_LIB)" (if you use the 32-bit version) or
"$(OPENNI2_LIB64)" (if you use the 64-bit version).
These are environment variables that point to the location of the OpenNI Lib directory. (The defaults are:
C:\Program Files\OpenNI2\Lib or
C:\Program Files (x86)\OpenNI2\Lib)
2-In the Linker section, under the input node, select
"Additional Dependencies"
and add
OpenNI2.lib or OpenNI2.lib
3-Ensure that you add the Additional Include and Library directories to both your Release and Debug configurations.
4-Copy all the files from OpenNI's redist directory (see environment variable "$(OPENNI2_REDIST)" or "$(OPENNI2_REDIST64)") to your working directory. (The defaults are
C:\Program Files\OpenNI2\Redist or
C:\Program Files (x86)\OpenNI2\Redist).
Be aware that when you run from command line, the working directory is the directory where the executable can be found, and where you run from Visual Studio the default directory is where the project file (.vcproj, .vcxproj) can be found.
you also need to point to the actual library file: openni2.lib
If you add all of options (Include, Lib, ...) to your project setting and again get this error, maybe your project platform is Win32 and you want to use OpenNI x64
In this case, you must change the platform to x64 (Project properties at the top of the page)
If you don't have x64 option, make a new one ;)

CMake finds the correct library, but VC++ attempts to link with something else

I have a CMake module to locate FreeGLUT:
FIND_PATH(FREEGLUT_INCLUDE_DIR NAMES GL/freeglut.h)
FIND_LIBRARY(FREEGLUT_LIBRARY NAMES freeglut freeglut_static)
SET(FREEGLUT_LIBRARIES ${FREEGLUT_LIBRARY})
SET(FREEGLUT_INCLUDE_DIRS ${FREEGLUT_INCLUDE_DIR})
INCLUDE(FindPackageHandleStandardArgs)
FIND_PACKAGE_HANDLE_STANDARD_ARGS(FreeGLUT DEFAULT_MSG FREEGLUT_LIBRARY FREEGLUT_INCLUDE_DIR)
MARK_AS_ADVANCED(FREEGLUT_INCLUDE_DIR FREEGLUT_LIBRARY)
It works fine and locates freeglut_static.lib when I generate NMake Makefiles on Windows. I'm attempting to statically link FreeGLUT into my DLL:
FIND_PACKAGE(FreeGLUT REQUIRED)
ADD_LIBRARY(vti SHARED ${VTI_SOURCES})
ADD_DEFINITIONS("-DBUILD_VTI=1 -DFREEGLUT_STATIC=1")
INCLUDE_DIRECTORIES(${CMAKE_SOURCE_DIR}/include ${FREEGLUT_INCLUDE_DIRS})
TARGET_LINK_LIBRARIES(vti ${FREEGLUT_LIBRARIES})
My source code builds correctly, but when it gets to the linking stage, VC++ fails with:
LINK : fatal error LNK1104: cannot open file 'freeglut.lib'
Which is strange since freeglut.lib isn't mentioned anywhere that I can see in the generated NMake makefiles. It should be trying to link with freeglut_static.lib, which CMake locates and sets in FREEGLUT_LIBRARIES.
What might be causing this?
This is caused with pragma directives in FreeGLUT code (see freeglut_std.h). Using FREEGLUT_STATIC should really fix that for you, but I think you should pass it to CMake without quotes: ADD_DEFINITIONS(-DBUILD_VTI -DFREEGLUT_STATIC)

Problem in Cross-Compiling libSDL for MIPS Platform

I was trying to compile libSDL-1.2.14 for my mips platform.
But it was not successful.
These were the steps that I tried out :
export PATH=/opt/mips-4.3/bin:$PATH
Went inside the libSDL-1.2.14 source folder.
Gave a "./configure --prefix=/usr/local/SDL_Lib --host=mips-linux-gnu"
Executed the "make" command
This was the error received :
cc1: warning: include location
"/usr/include" is unsafe for
cross-compilation
./src/audio/dma/SDL_dmaaudio.c: In
function 'DMA_WaitAudio':
./src/audio/dma/SDL_dmaaudio.c:167:
error: can't find a register in class
'COP3_REGS' while reloading 'asm'
./src/audio/dma/SDL_dmaaudio.c:167:
error: 'asm' operand has impossible
constraints make: *
[build/SDL_dmaaudio.lo] Error 1
But then i reconfigured the make file by giving the following commands :
make clean
./configure --prefix=/usr/local/SDL_Lib --host=mips-linux-gnu CPPFLAGS=-I/opt/mips-4.3/mips-linux-gnu/libc/usr/include/
make
NOTE : /opt/mips-4.3/mips-linux-gnu/libc/usr/include/ - This is the path where you can locate the select.h file for the mips Platform.
It contains the definitions of the macros FD_ZERO and FD_SET.
Still I am getting the same error.
cc1: warning: include location
"/usr/include" is unsafe for
cross-compilation
./src/audio/dma/SDL_dmaaudio.c: In
function 'DMA_WaitAudio':
./src/audio/dma/SDL_dmaaudio.c:167:

./src/audio/dma/SDL_dmaaudio.c:167:

Please help me with some valuable pointers.
Thanks,

First, don't set the path to the cross-compiler as the first part of your PATH, set it as last:
export PATH=$PATH:<path to cross-compiler>
It's safer this way. Second, run ./configure --help to get all the options. What that error message would say if it was smarter is the following:
You're trying to cross-compile since you're setting the --host flag
But you're not changing any of the other options for where to find includes and libs for the target environment
I'm going to use /usr/include by default
But that's for the host system which will not work when cross-compiling
Check what other configure options you need to set to tell the configure script where to find the .h files (includes) and the libraries for your target. These usually come with the cross-compiler that you download. Also, you should probably set the CROSS_COMPILE environment variable to the cross-compiler prefix before running configure. The prefix is the part before gcc in a cross-compiler, assuming you're using GCC as your cross-compiler.
