--- Comment #25 from Guido Falsi <madpi...@freebsd.org> --- (In reply to Jason E. Hale from comment #24) Hi, I've had a quick look and this one looks a little nasty. the output from present port tree (working) is: Compiling content-server translations Detected locale "C" with character encoding "US-ASCII", which is not UTF-8. Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead. If this causes problems, reconfigure your locale. See the locale(1) manual for more information. QRhiGles2: Failed to create temporary context QRhiGles2: Failed to create context This plugin does not support createPlatformVulkanInstance QVulkanInstance: Failed to initialize Vulkan Unable to detect GPU vendor. WebEngineContext is used before QtWebEngineQuick::initialize() or OpenGL context creation failed. Detected locale "C" with character encoding "US-ASCII", which is not UTF-8. Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead. If this causes problems, reconfigure your locale. See the locale(1) manual for more information. So the same up to "WebEngineContext is used before QtWebEngineQuick::initialize() or OpenGL context creation failed." This compilation code runs the actual calibre code, and at some point it instantiates WebEngine. Looks like in the past OpenGL context creation failure was not fatal, but now it is. I will need some time to investigate this and see if a solution is possible. Doe snot look like upstream has any patches about this at present. -- You are receiving this mail because: You are on the CC list for the bug.
