Hello I´m from colombia, i have been try to fix this problem 2 weeks ago.

i´m using a RPI3 B+ OS: jessie litte

Here the problem after running Webiopi default example

File "/usr/lib/python3.4/socketserver.py", line 305, in _handle_request_noblock self.process_request(request, client_address) File "/usr/lib/python3.4/socketserver.py", line 331, in process_request self.finish_request(request, client_address) File "/usr/lib/python3.4/socketserver.py", line 344, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/lib/python3.4/socketserver.py", line 669, in init self.handle() File "/usr/lib/python3.4/http/server.py", line 398, in handle self.handle_one_request() File "/usr/lib/python3.4/http/server.py", line 386, in handle_one_request method() File "/usr/local/lib/python3.4/dist-packages/WebIOPi-0.7.1-py3.4-linux-armv7l.egg/webiopi/protocols/http.py", line 267, in do_GET self.processRequest() File "/usr/local/lib/python3.4/dist-packages/WebIOPi-0.7.1-py3.4-linux-armv7l.egg/webiopi/protocols/http.py", line 258, in processRequest except (GPIO.InvalidDirectionException, GPIO.InvalidChannelException, GPIO.SetupException) as e: NameError: name 'GPIO' is not defined

How i fixed the error

1. run cat /proc/cpuinfo

will get revision number as a22082

1. then add this number in the cpuinfo.c located in /home/pi/WebIOPi-0.7.1/python/native as i show here in the next code. hope it work for you

int get_rpi_revision(void) { char revision[1024] = {'\0'};

if (get_cpuinfo_revision(revision) == NULL) return -1;

if ((strcmp(revision, "0002") == 0) || (strcmp(revision, "1000002") == 0 ) || (strcmp(revision, "0003") == 0) || (strcmp(revision, "1000003") == 0 )) return 1; else if ((strcmp(revision, "0004") == 0) || (strcmp(revision, "1000004") == 0 ) || (strcmp(revision, "0005") == 0) || (strcmp(revision, "1000005") == 0 ) || (strcmp(revision, "0006") == 0) || (strcmp(revision, "1000006") == 0 )) return 2; else if ((strcmp(revision, "a01041") == 0) || (strcmp(revision, "a21041") == 0 )|| (strcmp(revision, "a22082") == 0 )) return 3; else // assume rev 4 return 4;
