Hi Phil: I guess the above was just sent too late in the day in your time zone for you to catch the message. I did develop a cross-platform wxwidgets version check which is currently set to 2.8.12 (the current fairly ancient version for Debian wheezy) or above. In other words, it currently accepts virtually all versions of wxwidgets on modern Linux, but it could easily be adjusted so our minimum version is 3.0.0 (or whatever) if/when needed. I did not set the limit at 3.0.0 because it turns out that although I did have build success for 3.0.2 (an epa_built version that has worked before) there were run-time segfault issues with that version when running examplex/c/x01c -dev wxwidgets Therefore, because of the severe current build issues for wxwidgets 2.8.12 and current severe run-time issues with wxwidgets-3.0.2, I have decided to disable the wxwidgets device by default as a temporary emergency measure (as of commit ID bacd638). That means, those that are currently doing default run-time testing will not be affected by this, and those like you who want to test the device will need to specify -DPLD_wxwidgets=ON. My plan is to enable wxwidgets by default (so you no longer have to specify -DPLD_wxwidgets=ON) just as soon as these recently introduced build and run-time issues on Linux (and presumably other platforms) are straightened out.
