How to setup opcuaviewer example in QtCreator
James Mark Chan last edited by
Hi I'm trying to set up the opcuaviewer example in QtCreator in ubuntu 18.04.4 w Qt5.12 but I seem to have come across two issues:
- is that after compiling the opcua module in my local directory I have these:
jchan@jchan-Z170N:~/Qt5.12.6/5.12.6/gcc_64/lib$ ls -la *OpcUa* -rw-r--r-- 1 jchan jchan 742 Feb 5 17:44 libQt5OpcUa.la -rw-r--r-- 1 jchan jchan 1213 Feb 5 17:44 libQt5OpcUa.prl lrwxrwxrwx 1 jchan jchan 21 Feb 5 17:44 libQt5OpcUa.so -> libQt5OpcUa.so.5.12.6 lrwxrwxrwx 1 jchan jchan 21 Feb 5 17:44 libQt5OpcUa.so.5 -> libQt5OpcUa.so.5.12.6 lrwxrwxrwx 1 jchan jchan 21 Feb 5 17:44 libQt5OpcUa.so.5.12 -> libQt5OpcUa.so.5.12.6 -rwxr-xr-x 1 jchan jchan 1028576 Feb 5 17:43 libQt5OpcUa.so.5.12.6 -rw-r--r-- 1 jchan jchan 13759248 Feb 5 17:43 libQt5OpcUa.so.5.12.6.debug
but in qtcreator it seems to not be able to find my opcua module:
- the examples that i've copied and pasted from here:
don't seem to have a ui_certificatedialog.h
which is referenced in certificatedialog.cpp. Could I be missing some of the example files if so where would I get them or is this something that I should be implementing my self?
@James-Mark-Chan Your LIBS in pro file does not contain actual lib. It should be:
LIBS += -LPATH_TO_LIB_DIR -lQt5OpcUa
ui_certificatedialog.h will be generated when compiling.

Thank you for this post. I just discovered that I should have been using the examples from the qt clone instead of manually copying the text from the web url and it seems no LIBS += ... line was even needed as my creator was configured to use the default kit. It is launching now. I do wonder why my objects under the device folder node are not showing and will be looking into it.
