for some days now i have been struggeling with the following issue:
i have a C webapp running on a apache webserver, from this app i call to /sys/class/
gpio/... IO's by using a command like ->system("echo 1 > /sys/class/gpio/gpio5/value"). but this always results in a permission denied error in my apache error.log although i have done a chmod 777 on all the regarding files and i added the directory in the httpd.conf file.
please help me(!!!)
