Qt creator community 5.8 on ubuntu 16.04

Hi,

I'm trying to install Qt creator on Ubuntu. I have set to debug a random example program to see if it works but whatever the program I wanted to debug, I get this erro message :

22:49:19: Configuration unchanged, skipping qmake step.
22:49:19: Starting: "/usr/bin/make"

I precise : I'm on a dual boot with windows 10. (i don't if it can affect) and I have fond any post discuss about this problem on the net..

Thanks for your help by advance!

Hi,

Did you had an update to libdrm recently ?

@SGaist said in Qt creator community 5.8 on ubuntu 16.04:

pdate to libdrm

I have made some general updates but I don't know for this specially ,what should I verify ?

SGaist

AFAIK, drmGetDevice2 drmGetDevices2 are from that library. It's pretty strange that these symbols become suddenly missing. One thing you can try is to add LIBS += -ldrm but it shouldn't be needed.

@SGaist Your solution is working... Thank you.
However I don't get why I need to add this, Qt isn't supposed to make the link by itself ?

SGaist

It does, however there might have been a change in the dependencies in which case Qt may not yet be aware of that.
