library does not compile in ubuntu 16.04

[federicohyo]

Hi,

I just downloaded the library from the tag 2.1.
I have the following error while compiling it:

any ideas?
I look forward to your help.

I have no 16.04 machine yet, but for 14.04 I had to install Qt 5.6 by hand because the included version was too old (and something with OpenGL was broken).

[reini1305]

I'll try to reproduce the error using a fresh installation of 16.04 in a VM.

[reini1305]

I just downloaded a fresh copy of Ubuntu 16.04 from osboxes.org (64-bit). There I installed the following things using apt:

• cuda-toolkit-8-0
• libopencv-dev
• libqt5widgets5
• libqt5opengl5-dev

I could not reproduce your above error, the library compiled fine (including iuguiand iuio). You mentioned the tag 2.1, maybe try a checkout from master?

[reini1305]

Did you make any progress on this?

[federicohyo]

Hi,
yes I have been able to compile imageutilities.
I had to update cuda toolkit from 7.5 to 8.

thank you a lot for your support.
