hello,

i have dedicated some time to updating my system, ending up with ubuntu 14.04 doing the occasional patching now. everything pd related went relatively painless, just had to rebuild Gem, but gridflow's stuck and won't move a bit and i have no clue.

i have gridflow in it's own builddir: /home/ub/build/gridflow here i do update per svn, then configure and make, but when loading in pd i consistently get:

home/ub/build/gridflow/gridflow.pd_linux: /home/ub/build/gridflow/gridflow.pd_linux: undefined symbol: cvEllipse gridflow: can't load library /home/ub/build/gridflow/gridflow_gem9393.pd_linux: /home/ub/build/gridflow/gridflow_gem9393.pd_linux: undefined symbol: _ZTI7FObject gridflow_gem9393: can't load library

system is amd64, pd: 0.43-3, GEM: 0.93.3, gridflow says it's "At revision 6881"

ideas anyone?

thanks+ciao, ub

hello, it seems that gem libraries aren't linked correctly by the build system, gridflow might run if Gem libs are disabled in configure, what about posting build logs?

thanks for the quick reply.

i tried ./configure --no-opengl upon make distclean but that lead to the same result for gridflow.pd_linux: undefined symbol: cvEllipse

as this seems an openCv object, which is included directly by gridflow (not via Gem) from src/opencv.cxx i checked the config.log for opencv and really there was a line saying: "Package opencv was not found in the pkg-config search path"

installing libopencv-dev fixed that and it's all good now :)

thanks+cheers, ub
