OS: Windows 8.1 Perl: Strawberry Perl 5.30.0.1 (64bit) wxWidgets: Version 3.0.2 - automatically selected and downloaded by cpan Cpan was used to install Wx, which attempted to install wxWidgets and Alien::wxWidgets as dependencies. Both of these built and installed without error. Wx, however, fails to build. All programs in Wx-0.9932-0\ext fail with the same error: "'my_perl' was not declared in this scope". Research indicates this is related to threads.
