[Coin-discuss] Re: Coin-discuss digest, Vol 1 #98 - 1 msg

[Al Lee]

Yes, I ran bcps with the parameter file in the current
directory but it brought the same result. I traced
down the error using gdb and it was trying to open a
file "graphic.in" whose existence is completely
oblivious. Do you have any clue about what is going
wrong?

Thanks,
Al
