undefined symbol: pcre2_jit_stack_create_16

edit

When I run rtq I get the following error:

Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
Traceback (most recent call last):
  File "/home/pi/ros_catkin_ws/install_isolated/lib/python2.7/dist-packages/qt_gui_cpp/cpp_binding_helper.py", line 43, in <module>
    from . import libqt_gui_cpp_sip
ImportError: /home/pi/ros_catkin_ws/install_isolated/lib/python2.7/dist-packages/qt_gui_cpp/libqt_gui_cpp_sip.so: undefined symbol: pcre2_jit_stack_create_16

I am fairly sure that pcre2_jit_stack_create_16 is in libqtpcre2.a which is in /usr/lib. So I don't see why it can't be found. Any suggestions?
