Crash when compiling and running SensorBox

[paniq]

I'm getting a crash when SensorBox starts. The OVR is plugged in and has 0666 permissions.

terminate called after throwing an instance of 'boost::exception_detail::clone_implboost::exception_detail::error_info_injector<boost::system::system_error >' what(): assign: Bad file descriptor

I used this line to build:

gcc SensorBoxTest.cpp -I../../LibOVR/Include -I../../LibOVR/Src ../../LibOVR/Lib/Linux/Debug/libOculus.so ../build/Debug/libCommonSrc.a -o SensorBox -lGL -lpthread -ludev -lboost_thread -lboost_system -lglut

The stack trace shows this:

Oops, my bad - the permissions weren't set up correctly. It would be nice to get a more helpful error diagnosis here. ;)

Question is: how DO I setup the permissions correctly? (I manually chmodded all hiddraw* devices for now, but what would be the proper udev line to get this fixed?)

[jherico]

I used this as 99-hid..rules:

SUBSYSTEM=="hidraw", MODE="0666"

and then ran "sudo udevadm test -a -p udevadm info -q path -n /dev/hidraw0" (replace the path with the appropriate /dev/hidrawX path for your Rift.

You can see the output and look at the permissions of the hidraw device after to see if they're correct. I'll see if I can find a way to improve the error message output for a permissions issue.

FYI, the above udevrule is pretty insecure, obviously. I just use it for development. I intend to include a utility that will allow users to execute a command that will examine and fix permissions by putting in a much more specific rule, but since that wasn't on the critical path, it didn't make it into the initial release.

whoops. didn't mean to close it, not used the githibs interface
