• install the wxWidget 3.x development files (headers etc.) supplied for your distribution. (See "Other
requirements" above).
• fetch, compile and install the wxWidget 3.x packet from source downloaded from the website
( http://www.wxwidgets.org ).
• alter the Makefiles so as to find the wxWidget configuration script called wx-config.
The files you may need to alter are to be found here:
apps/mvPropView/Makefile.inc
You will find the compiled test programs in the subdirectories "apps/.../x86" . For 64 bit systems
it will be "apps/.../x86_64" . For ARM systems it will be "apps/.../arm" .
If you cannot build the wxWidget test program you should, at least, be able to compile the text-based
test programs in
apps/SingleSnap , apps/LiveSnap , etc.
(d) It may be possible to run applications as a non-root user on your system if you are using the udev
system or a fairly recent version of hotplug.
7.2.2.2 For udev (e.g. Gentoo
∗
, OpenSuSE 10.0 - 10.1)
Add the following 2 rules to one of the files in the directory "/etc/udev/rules.d" or make a new file in this
directory (e.g. "/etc/udev/rules.d/20-mvbf.rules" ) containing the lines below:
ENV{UDEVD_EVENT}== "1" , ACTION== "add" , BUS== "usb" , ENV{PRODUCT}== "164c/101/0" , /
RUN+= "/bin/sh -c ’chmod 0664 $env{DEVICE}; chgrp usb $env{DEVICE}’"
ENV{UDEVD_EVENT}== "1" , ACTION== "add" , BUS== "usb" , ENV{PRODUCT}== "164c/103/0" , /
RUN+= "/bin/sh -c ’chmod 0664 $env{DEVICE}; chgrp usb $env{DEVICE}’"
You will find an example file "20-mvbf.rules" in the scripts directory after installation.
Note
Do not forget to add your user to the usb group! You may have to create the group first.
Current Gentoo systems support udev with a minimal, legacy hotplug system. It is usually sufficient to add any
usernames that are to be used for the mvBlueFOX to the group "usb" because there is already a udev rule giving
write permission to all USB devices to members of this group. If this does not work then try the other alternatives
described here. The udev method is better because hotplug is likely to be removed eventually.
7.2.2.3 For udev (OpenSuSE 10.2 - 10.x)
In "/etc/fstab" in the line starting with usbfs change noauto to defaults
Afterwards either restart the system or execute "mount -a"
In "/etc/udev/rules.d/50-udev-default.rules" (or similar) change the line after a comment re-
garding libusb . Change 'MODE="0644"' in 'MODE="0664", GROUP="users"'
Connect the camera to the system now or re-connect it if it has been connected already
In case the environment variable USB_DEVFS_PATH is not set, it needs to be set to "/dev/bus/usb" ( 'export US
← -
B_DEVFS_PATH="/dev/bus/usb"' .
