Hi,
Thanks to Vishak and AWG I was able to cross compile DirectFB for Arm platform,
but now when I run sample application like directvnc, I am getting the
following error,
"DirectFB/core/system: No system found,"
dfb.c <47>:
(#) DirectFBError [DirectFBCreate( &dfb )]: No (suitable)
implementation found!
I have built directvnc by linking it to static library of directfb
(libdirectfb.a).
With Best Regards,
C. N. Harsha Sukeerthi

Hi Vishak,
Thanks for your help, but,
Config.log is not that descriptive, it provides information in the following
format:
"Config:6754: checking for jpeglib.h"
I have enabled the debug option while configuring.
With Best Regards,
Harsha Sukeerthi

Hi AWG,
Sorry I did not the get the part where you mentioned to check for .pc and .la
files?? Which .pc file should I have to check??
After building jpeg, png, zlib and freetype did not provide any .pc files to
add to the PKG_CONFIG_PATH
I have tried CPPFLAGS with CFLAGS and CPPFLAGS alone but it did not work.
Thanks for your help.
With Best Regards,
C. N. Harsha Sukeerthi
