Subject: Undefined symbol "perl_clone" (0.65)
The test suite fails on most of my smokers like this: ... # Failed test 'use MPV::Simple;' # at t/MPV-Simple.t line 12. # Tried to use 'MPV::Simple'. # Error: Can't load '/usr/home/cpansand/.cpan/build/2020042606/MPV-Simple-0.65-4/blib/arch/auto/MPV/Simple/Simple.so' for module MPV::Simple: /usr/home/cpansand/.cpan/build/2020042606/MPV-Simple-0.65-4/blib/arch/auto/MPV/Simple/Simple.so: Undefined symbol "perl_clone" at /usr/perl5.28.1Dp/lib/5.28.1/amd64-freebsd-ld/DynaLoader.pm line 193. # # Compilation failed in require at t/MPV-Simple.t line 12. # BEGIN failed--compilation aborted at t/MPV-Simple.t line 12. # Looks like you failed 1 test of 1. t/MPV-Simple.t ..

On some systems (e.g. threaded perl 5.31.10 on Ubuntu 18.04) it's another missing symbol: # Failed test 'use MPV::Simple;' # at t/MPV-Simple.t line 12. # Tried to use 'MPV::Simple'. # Error: Can't load '/home/cpansand/.cpan/build/2020042606/MPV-Simple-0.65-6/blib/arch/auto/MPV/Simple/Simple.so' for module MPV::Simple: /home/cpansand/.cpan/build/2020042606/MPV-Simple-0.65-6/blib/arch/auto/MPV/Simple/Simple.so: undefined symbol: mpv_destroy at /opt/perl-5.31.9t/lib/5.31.9/x86_64-linux-thread-multi/DynaLoader.pm line 193. # # Compilation failed in require at t/MPV-Simple.t line 12. # BEGIN failed--compilation aborted at t/MPV-Simple.t line 12. # Looks like you failed 1 test of 1. t/MPV-Simple.t ..

> Possibly perl_clone is only available in threaded perls.
Dear Slaven Rezic, Thanks for the hint. The new version uses mpv_set_wakeup_callback() which runs a callback in a foreign thread. The callback changes a perl variable which signaled, that new events occured. In the old version everything of this happened in C. Therefore indeed MPV::Simple needs a threaded perl. For now I will add a simple check and clone the perl context only in threaded environments. Nevertheless the modul will not run correctly in non threaded perls! Best wishes, Max

Dear Slaven Rezic, Regarding the mpv_destroy problem, I think, on Ubuntu 18.04 there is an old mpv version? Because the binding doesn't need mpv_destroy I deleted the funtion in the XS file in ver. 0.66. I hope, this solves this issue... Best wishes, Max

Okay, I hope the test issues are solved in 0.67. Perhaps you can test this again? Thanks in advance, Max

Yes, things look better now. No more failures on my smokers.
