It's strange - if I run: ./pharo -headless Pharo6App.image eval "MyApp run"
then I get the error: /libSDL2-2.0.so.0: cannot open shared object file: No such file or directory/ But the main pharo window opens up followed by my OS WIndow. So that works fine despite the seeming error, But if I run ./pharo *-headless* Pharo6App.image eval "MyApp run" then I get the same error but no window opens up at all. -- View this message in context: http://forum.world.st/Launching-OSWindow-windows-when-in-headless-mode-tp4928139p4928142.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
