Hi,
it looks like i can't capture with recordmyDesktop... i only get error code 256
/ 2816
I would like to give [pdp_rec~] a try, but i can't make a [pix_2pdp] object. The
error message here is:
/usr/lib/pd-extended/extra/pix_2pdp.pd_linux:
/usr/lib/pd-extended/extra/pix_2pdp.pd_linux: undefined symbol:
_ZN9CPPExtern4postEPKcz
but the object is there and the help file refers to pix_freeframe, which could
be because of the version of GEM from svn.
