Compiling PTAM (Win32)

It took quite some time to get everything working. Here is a quick break-down. Compling works fine. But PTAM isn't doing anything meaningful so far. Everything was done using Visual Studio 2010 Ultimate.

1. get the PTAM source code
   • unpack and read the containing README.txt
2. get all dependencies named in the README.txt
   • fltk-2.0
   • gvars3 (see 3. )
   • jpeg-6b
   • libvcd (see 3. )
   • pthreads
   • TooN
   • 1394camera645
   • glew 1.6.0
   • lapack
3. I noticed that the code revision for gvars3 and libvcd, which is referenced in the README.txt, dosen't work quite well. So I took the HEAD revision (date: 19.05.2011)
4. unpack all dependencies (some come as self-extracting or install packages, so it is necessary to watch where the files go and move all the one place)
5. adjust the include/library paths of libvcd and gvars3 and compile both (using the included VC2005 projects)
   • gvars3 include:
     $(ProjectDir)..\..;$(ProjectDir)..\..\..;$(ProjectDir)..\..\..\pthreads\Pre-built.2\include;$(ProjectDir)..\..\..\fltk-2.0;%(AdditionalIncludeDirectories)
   • libcvd include:
     ..\..;$(ProjectDir)..\..\..\jpeg-6b\include;$(ProjectDir)..\..\..\pthreads\Pre-built.2\include;$(ProjectDir)..\..\..\
   • libcvd lib:
     $(ProjectDir)..\..\..\jpeg-6b\lib;$(ProjectDir)..\..\..\pthreads\Pre-built.2\lib
6. (from now on everything in the PTAN project) adjust the include/lib paths also
   • include paths:
     include;$(ProjectDir)..\ptam dependencies;$(ProjectDir)..\ptam dependencies\gvars3;$(ProjectDir)..\ptam dependencies\pthreads\Pre-built.2\include;$(ProjectDir)..\ptam dependencies\libcvd
   • lib paths:
     $(ProjectDir)..\ptam dependencies\pthreads\Pre-built.2\lib;$(ProjectDir)..\ptam dependencies\gvars3\lib;$(ProjectDir)..\ptam dependencies\libcvd\lib;lib
7. open SymEigen.h and search for //calculate eigenvalues (at line 184)
   replace in the next line the two calls of sqrt from sqrt(3) to sqrt(3.0)
8. add /FORCE:MULTIPLE to the linker options (suggested by JC) and compile
9. copy the following dlls from the dependencies to the Release folder
   • pthread*.dll
   • glew32.dll
   • lapack_win32_MT.dll, blas_win32_MT.dll
10. run PTAM.exe
