Error: "Please install SW4STM32 toolchain to open the project. Or associate the file type of the project with your Toolchain in System Default Program Settings"
associate .cproject file with Ac6. I don’t know how to do it on Mac but in gnome based linux make “application/x-SystemWorkbench=sw4stm32.desktop” entry to “/usr/share/applications/defaults.list”
I presume you have sw4stm32.desktop file in /usr/share/applications folder. If not make a desktop shortcut for Ac6 and name it sw4stm32 then copy that file to /usr/share/applications folder.
any modification on defaults.list file and/or copying a file to /usr/share/applications folder require root password.
