[Rtk-users] Fwd: Remote Control Issue

[Simon Rit]

Hi Guangming and all,
Thanks for reporting this change of behavior. My first answer is that what
you find simple is not so simple... but you're right, v1.0.0 allowed to
compile RTK with CUDA and to run it without a CUDA device. After a bit of
trakcing, I found that the change of behavior has been introduced with this
patch
<https://github.com/SimonRit/RTK/commit/435c858b598f2bdad01d41760109acf347c98fb4>
so you can blame me. It has now fixed this issue with this patch
<https://github.com/SimonRit/RTK/commit/3a549c10193ecdbcd3a9192db53feb7b34eb80da>,
which seems to work on my laptop, I hope it does on your computer as well.
I can't help you with the fact that you can't run CUDA software with remote
control.
Simon
