problem compiling the example

[federicohyo]

Hi there!

thank you very much for sharing this code. I am Federico and I work at IniLabs GmbH, we produce and sell the neuromorphic vision sensors.

I am now trying to compile your code, however I am getting the following error, do you have any ideas on how to solve this?

thank you very much for your support. I look forward seeing the intensity reconstruction in live action.

attached the log

Hi! Did you manage to build the imageutilities with the iugui module? Before you edited your comment, you had a compiler error on that one IIRC. Seems like it can't link iugui. What is your system configuration?

Hi, thank you for your quick reply.

My current configuration is Ubuntu 16.04, gcc 4.9 and I cannot compile imageutils, I have CUDA 7.5 and an NVIDIA GPU.

Here is the log when I try to build imageutilities.

This issue is a direct consequence of https://github.com/VLOGroup/imageutilities/issues/1 so I'll close this one here for now.

Hi! I am now running the code, pretty neat!

Thank you for sharing.
