^ this error?  I've seen that before and never could figure it out, nor was it ever the
cause of any problem running valgrind.

I would say build your own wxwidgets from the 3.0.1 source.  We're dealing with an unknown
problem, so one has to revert to probabilities at that point.

I think the highest probability is that there is some incompatibility in your software
stack.  Building wx from source is an easy experiment.  You do not have to remove the wx
package if it makes codelight happy.

Follow the instructions I gave in an earlier email today.  Then after configuring the
kicad build, I run

(ccmake is in the package cmake-curses-gui I think.)

$ ccmake .

in the build directory.  Then I paste in

  /opt/wx3.0-stl/bin/wx-config

into the field named:  wxWidgets_CONFIG_EXECUTABLE and reconfigure in ccmake.

Likewise for the debug build, which over time will be very helpful for you.


Obviously the first part of the /opt/wx3.0-stl/bin/wx-config string came from the --prefix
argument to the wx configure command.

Don't forget to run $ sudo ldconfig
after installing the home made wx libraries.
