Package configurations -- what are they?

[jiapei100]

Hi, all:

For VTK (kitware) configuration,
I met the following configuration things,
which I need some clear explanation. Please do help




CMAKE_HP_PTHREADS OFF // what is HP_PTHREADS ?? It seems there are several types of pthreads.
CMAKE_USE_SPROC OFF // yes, sorry, till now, I've got no idea what is SPROC ?
// what for? See this many times in various packages

FFMPEG_INCLUDE_DIR FFMPEG_INCLUDE_DIR-NOTFOUND
// using Ubuntu 9.10, it looks like VTK only supports FFMPEG <= 0.5.
// the default FFMPEG in current Ubuntu 9.10 now doesn't afford an single "include" directory.

FFMPEG_dc1394_LIBRARY FFMPEG_dc1394_LIBRARY-NOTFOUND
FFMPEG_dts_LIBRARY FFMPEG_dts_LIBRARY-NOTFOUND
// why FFMPEG_dc1394 and FFMPEG_dts?
I installed libdc1394-22-dev ,
but it seems this has nothing to do with FFMPEG ???

MEMORYCHECK_COMMAND MEMORYCHECK_COMMAND-NOTFOUND
// Couldn't find any package related to MEMORYCHECK ? which package is required for this package?

OPENGL_xmesa_INCLUDE_DIR OPENGL_xmesa_INCLUDE_DIR-NOTFOUND
// strange tha under Ubuntu 9.10, this can not be found.
All mesa related packages have been installed including
libgl1-mesa-dev
libglu1-mesa-dev
libglw1-mesa-dev
libosmesa6-dev
mesa-common-dev
xlibmesa-gl-dev
xlibmesa-glu

Only except package "libgl1-mesa-swx11-dev".
However, if I tick this up, package "ubuntu-desktop" will be removed,
as well as some conflicted mesa packages listed above.
So, what is "OPENGL_xmesa_INCLUDE_DIR" for?


LIBPROJ4_INCLUDE_DIR LIBPROJ4_INCLUDE_DIR-NOTFOUND
LIBPROJ4_LIBRARIES LIBPROJ4_LIBRARIES-NOTFOUND
// In fact, I installed libproj-dev from current Ubuntu 9.10 repository. But,


PROJ_LIST_EXTERNAL OFF
PROJ_USE_GSL OFF
PROJ_USE_PTHREADS OFF
// What are these three choices for? If I picked ON for any of the three, I will obtain the following error message:
CMake Error at Utilities/vtklibproj4/CMakeLists.txt:28 (message):
You may not define both PROJ_LIST_EXTERNAL and BUILD_SHARED_LIBS. Turn one
off and re-run CMake.
Therefore, it's better I turn off these 3 choices right?

VERDICT_BUILD_DOC OFF
VERDICT_ENABLE_TESTING OFF
VERDICT_MANGLE ON
VERDICT_MANGLE_PREFIX vtk
VERDICT_USE_FLOAT OFF
// What are VERDICT for? Always meet this in many packages. Something is even more strange. If I enable "VERDICT_ENABLE_TESTING ON", after the configuration, it will be automatically change back to "VERDICT_ENABLE_TESTING OFF" !!! Amazing.... The same thing happens to "VERDICT_USE_FLOAT OFF" as well.

VLI_LIBRARY_FOR_VP1000 VLI_LIBRARY_FOR_VP1000-NOTFOUND
// what is this for? It seems nothing is related with this choice in Ubuntu 9.10?


X11_XTest_LIB X11_XTest_LIB-NOTFOUND
X11_Xaccessrules_INCLUDE_PATH X11_Xaccessrules_INCLUDE_PATH-NOTFOUND
// Strange that in ubuntu 9.10, these 2 packages are not able to be found. What are these 2 packages for?



Finally, I really hope all VTK_ settings can be carefully explained
because all these parameters are specifically for VTK !!
Here, I enumerate all I'm interested in as follows:

VTK_LARGE_DATA_ROOT VTK_LARGE_DATA_ROOT-NOTFOUND
// what is LARGE_DATA? is it VTKData? My directory tree is just like
some folder
----------- VTK
----------- VTKData
How should I arrange these 2 directories "VTK" and "VTKData"?

VTK_LEGACY_REMOVE OFF
VTK_LEGACY_SILENT OFF
// What are VTK_LEGACY for?

VTK_OPENGL_HAS_OSMESA OFF
// what is OSMESA? what's the relationship between opengl and osmesa?

VTK_TESTING_USE_FPE ON
// what does FPE refer to??
VTK_TESTING_USE_LOCALE OFF
// what does LOCALE refer to?

VTK_USE_FFMPEG_ENCODER OFF
// As you may see above, FFMPEG_INCLUDE_DIR FFMPEG_INCLUDE_DIR-NOTFOUND , so it's better for me to turn off VTK_USE_FFMPEG_ENCODER .

VTK_USE_MANGLED_MESA OFF
// OPENGL_xmesa_INCLUDE_DIR OPENGL_xmesa_INCLUDE_DIR-NOTFOUND , so it seems i'd better turn off VTK_USE_MANGLED_MESA

VTK_USE_MPEG2_ENCODER OFF
// This seems to be specific for vtkmpeg2encode, right?
which one should be installed first?
vtk or vtkmpeg2encode?
why not afford a standard installation for vtkmpeg2encode?
Or just integrate VTK and vtkmpeg2encode??

VTK_USE_TDX ON
// What is TDX for?
VTK_USE_TEXT_ANALYSIS ON
// What is TEXT_ANALYSIS for?

VTK_USE_VOLUMEPRO_1000 OFF
// What is VOLUMEPRO_1000?




Hope anybody can afford a detailed explanation on all the above VTK configuration settings.

Thank you very much.

Best Regards

Personally, I have never studied the parameters in detail. I have no idea what those do. Accepting the defaults have always worked for me.

You can see short parameter descriptions using cmake's gui. It is installed by...


sudo apt-get install cmake-gui

To start the gui go to Applications -> Programming -> CMake. Set the source and binary directories for vtk. Click "configure" which after completion (if I remember correctly), should show all the parameters. To see what a parameter does, hold your mouse cursor over its name. A description should popup after a few seconds.

By the way, I like the website in your signature :)

If you don't have GUI (e.g only terminal as in server version).
Then just install ccmake which is more convenient (GUI-like) running in terminal.

sudo apt-get install cmake-curses-gui
ccmake <whatever CMakeLists.txt>
