In addition mount can set a device as noexec which pretty much is an good idea for devices as USB-sticks or unknown CD/DVD. Using udev or something else, somewhere else it can be also configured (read: than it depends, what you are using to mount the stick) On traditional Linux systems this can be configured in /etc/fstab. to execute something is based on the umask used for mounting. BTW: When compiling a C file via Geany, it's already set to be executable.Īs you mention your USB stick is formatted with FAT32 which is not supporting the POSIX things here so chmod will not take any effect. So chmod +x should work on most systems using e.g. x-x-x or in hex 0111 on POSIX file systems. Gordon – have recently downloaded this update with added serial commands.To run a file on Linux the user needs to have the x either on user or group. WiringPi is released under the GNU Lesser Public License version 3. That should give you some confidence that it’s working OK. Run the gpio command to check the installation: gpio -v Remmeber the actual filename will be different – you will have to check the name and adjust accordingly. Reboot the computer: Code: Select all sudo reboot Check to see if you can access the external drive using the file manager.

You then need to do this to install: tar xfz Note that the numbers and letters after wiringPi (98bcb20 in this case) will probably be different – they’re a unique identifier for each release. Permission denied while trying to install OpenVPN. This will download a tar.gz file with a name like .

Raspbian), you can install it with: sudo apt-get install git-core .108 of Chromium included Mesa updated to 19.3.2 for OpenGL ES 3.1 conformance Pixel doubling option added in Raspberry Pi Configuration on. Raspberry Pi hardware permissions can be quite tricky. If you do not have GIT installed, then under any of the Debian releases (e.g. WiringPi is now maintained under GIT for ease of change tracking, however there is a Plan B if you’re unable to use GIT for whatever reasons (usually your firewall will be blocking you, so do check that first!)
