Re: [SIP-devel] SIP and SIVP

[ZHANG, C. <zha...@gm...>]

Hi, Ricardo,

I noticed that there is another Image Processing Toolbox project
http://forge.scilab.org/index.php/p/IPD/

It seems to me that SIVP and IPD are gaining more popularizes than SIP. And
people are reinvesting the wheels over and over again.

Motivated by your previous email I made an attempt to build SIP for Window
last month. I added some CMakeLists.txt into CVS to make the build more
easier. But I noticed that the C code in CVS was heavily dependent on GNU
build toolchain. The config.h generated by running ./configure played a
irreplaceable role for a successful build under Linux. That is hard for code
to be build with CMake. By the way I also noticed that C99 syntax features
seemed to be used in the CVS code which were also badly supported by Visual
Studio.

I've been doing all my research under Linux these years. So porting to
Windows doesn't appear to be interesting to me even though I did it several
years ago.

Regards,
Cheng
