Hi, all:

I dropped this Email just in order to understand the configuration for VXL
compilation thoroughly.

My configuration for compiling current VXL SVN  is as follows, which brings
me a successful configuration before "make" !!

 XERCES_NEW_BXML_LIBRARY_PATH     XERCES_NEW_BXML_LIBRARY_PATH-NOTFOUND

However, I tried the following configurations with failure, I really want to
know why it is so and what happened to these settings.

1) if
BUILD_FOR_VXL_DASHBOARD          OFF

I got the following error message for configuration
 CMake Error: The following variables are used in this project, but they are
set to NOTFOUND.
 Please set them or make sure they are set and tested correctly in the CMake
files:
 MPEG2_vo_LIBRARY
     linked by target "vidl1" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/core/vidl1
     linked by target "vidl_vil1" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/core/vidl_vil1
     linked by target "oxp" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/contrib/oxl/oxp

So, what is BUILD_FOR_VXL_DASHBOARD for?

2) if
 BUILD_UNMAINTAINED_LIBRARIES     ON
I got the following error message for configuration
CMake Error: The following variables are used in this project, but they are
set to NOTFOUND.
 Please set them or make sure they are set and tested correctly in the CMake
files:
 MPEG2_vo_LIBRARY
     linked by target "vidl1" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/core/vidl1
     linked by target "vidl_vil1" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/core/vidl_vil1
     linked by target "oxp" in directory
/home/jiapei/Tools/CV/vxl-svn-20091206/contrib/oxl/oxp

So, what is BUILD_UNMAINTAINED_LIBRARIES for? What are those unmaintained
libraries.

3) if
BUILD_VGUI                       ON
This will brings me a lot of GUI choices including GTK, QT, X11, etc. ignore
this setting

4) What is ECW_INCLUDE_DIR                  ECW_INCLUDE_DIR-NOTFOUND
 for ? What is ECW? On my Ubuntu 9.10, I don't have ECW package in the
default repository at all.

5) FFMPEG now seems to be well supported

FFMPEG_CONFIG                    FFMPEG_CONFIG-NOTFOUND
 FFMPEG_INCLUDE1_DIR              FFMPEG_INCLUDE1_DIR-NOTFOUND
 FFMPEG_INCLUDE2_DIR              /usr/include
 FFMPEG_avcodec_LIBRARY           /usr/lib/libavcodec.so
 FFMPEG_avformat_LIBRARY          /usr/lib/libavformat.so
 FFMPEG_avutil_LIBRARY            /usr/lib/libavutil.so
 FFMPEG_swscale_LIBRARY           /usr/lib/libswscale.so

I guessed
FFMPEG_CONFIG                    FFMPEG_CONFIG-NOTFOUND
 FFMPEG_INCLUDE1_DIR              FFMPEG_INCLUDE1_DIR-NOTFOUND

are for old FFMPEG, while

 FFMPEG_INCLUDE2_DIR              /usr/include
 FFMPEG_avcodec_LIBRARY           /usr/lib/libavcodec.so
 FFMPEG_avformat_LIBRARY          /usr/lib/libavformat.so
 FFMPEG_avutil_LIBRARY            /usr/lib/libavutil.so
 FFMPEG_swscale_LIBRARY           /usr/lib/libswscale.so

are for FFMPEG 0.5 or above, right??

6) What is MPEG2_vo_LIBRARY                 MPEG2_vo_LIBRARY-NOTFOUND
 for?? Which package is required for this setting?

7) VCL_INCLUDE_CXX_0X can be ON and OFF, both are ok for configuration
But, what is VCL_INCLUDE_CXX_0X  for?

8) if
VIL_CONFIG_ENABLE_SSE2_ROUNDIN   ON
I got the following error message for configuration

 The current compiler flags do not allow the SSE2 instructions to be used.
It looks like if you add the flag
 '-msse2' you will be able to use the SSE2 instructions. If you make this
change and still see this message,
 you may need to set VXL_UPDATE_CONFIGURATION to ON.

 CMake Error at core/vil/CMakeLists.txt:102 (MESSAGE):
   Cannot have VIL_CONFIG_ENABLE_SSE2_ROUNDING because there is no SSE2
   hardware support

Strange why is it so?

9) What are XERCES_BXML and XERCES_NEW_BXML?

 XERCES_BXML_INCLUDE_PATH         XERCES_BXML_INCLUDE_PATH-NOTFOUND
 XERCES_BXML_LIBRARY_PATH         /usr/lib/libxerces-c.so
 XERCES_NEW_BXML_INCLUDE_PATH     XERCES_NEW_BXML_INCLUDE_PATH-NOTFOUND
 XERCES_NEW_BXML_LIBRARY_PATH     XERCES_NEW_BXML_LIBRARY_PATH-NOTFOUND

I installed package libxerces-c-dev already. But I've got no idea what are
XERCES_BXML and XERCES_NEW_BXML respectively for?

Please, can anybody give me a detailed explanation for all these settings of
VXL?

Best Regards
JIA Pei
