Oh, thanks<br>
<br>
I tried what you said, and this example works! So I suppose the
problem is in the imshow() function. It's <span class="tag_e"><span
class="tag_t">annoying but no blocking so go go go.<br>

Thanks<br>

<pre wrap="">Hi JoseAntonio,
that seems more an OpenCV problem than a JdeRobot one :-)
The "init done opengl support available" are warning messages
according to these webs [1][2]. Try to explore the OpenCV example
demos, like grabcut.py to check that OpenCV is working fine on your
machine.
Cheers,
JoseMaria

<pre wrap="">Hi all, I update my situation.
I did a apt-get dist-upgrade and the import problem disappeared. However i
can't do a simple read image and show it.
I do
im = cv2.imread('images/plazaMayor600x600.png');
cv2.imshow('image',im)
And i get
init doneSef
opengl support available
And a window open and close with no error. If i execute from terminal I get
the same problem however produces a crash on ubuntu with more information:
"Segfault happened at 0x7f5fe89fb629 can't access to this direction not
located in a know VMA region
Stack memory exhausted"
Thanks everybody

Hi all,
I've a problem when i do the import in my python code. In this simple line
of code my program crashes:
from cv2 import *
With the following error:
ImportError: /usr/lib/x86_64-linux-gnu/libQt5OpenGL.so.5: undefined symbol:
_ZN15QStaticTextItem13setFontEngineEP11QFontEngine
I not have idea of what is wrong I installed the jderobot from apt
repositories an it didn't give me any problem
thanks all
