Hello,
i finally have an evaluation licence for the HALCON lib, for 1 month.
cool.
i compile the halcon plug-in like explain in the readme. compilation was no problem. in Gem/src, i did a : ln -s plugins/*/.libs/*.so .
so i've got 5 gem_video plug in : DC1394, DV4L, HALCON, V4L, V4L2
not necessarily. you have compiled 5 plugins, but some of them might not have enabled their code. e.g. if configure cannot find libdv, then you will end up with a bare gem_videoDV4L.so, that basically does nothing.... anyhow
so, why did DV4L is not listed?
see above.
is DC1394 replacing it?
no, dc1394 uses idc (industrial video over ieee1394), wherase dv4l uses IEC 61834 (aka: consumer a/v over ieee1394)
i try to cp libhalconcpp.so in diferents place, but i still have the same error. what sould i do so that gem_videoHALCON.so can load libhalconcpp.so?
did you follow the steps in plugins/videoHALCON/README.txt that say: <snip> probably this won't work, with Gem complaining that it cannot find "libhalconcpp.so" or similar. in this case should tell the linker where to find the halcon-libraries, using the LD_LIBRARY_PATH variable: $ LD_LIBRARY_PATH=${HALCONROOT}/lib/${HALCONARCH} pd -lib Gem should do the trick. </snip>
