12 On Fedora, gclib and \link gcaps \endlink are distributed in RPM repositories. The following steps can be performed to install.
13
14 ### Download Galil's repository information
15
16 Point a browser at http://www.galil.com/sw/pub/fedora/galilrpm-3-1.noarch.rpm and install the rpm.
17 This installs Galil's RPM repositories and can be done from the terminal with the following.
18
19 $ wget http://www.galil.com/sw/pub/fedora/galilrpm-3-1.noarch.rpm
20 # rpm -Uvh galilrpm-3-1.noarch.rpm

30
31 Following Linux's daemon naming conventions, gcaps is called *gcapsd* on Fedora.
32 See the \link gcaps \endlink documentation for more information.
33
34 # yum install gcapsd
35
36 Verify that the systemd unit is running.

54 ##Serial Ports and USB
55 If access to the serial ports or USB (e.g. DMC-4103) is desired through gclib, the following will provide steps to join the correct access group. If using USB, be sure the controller is powered and the usb is plugged in before beginning.
56
57 ###Determine group with access
58
59 $ ls -l /dev/ttyUSB* /dev/ttyS*
60 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
61 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
62 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
63 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
64 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
65
66 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
67
68 ###Add the desired *username* to the group.
69
70 $ sudo gpasswd -a username dialout
71 [sudo] password for username:
72 Adding user username to group dialout
73
74 Log out and back in for change to take effect.
75
76 $ groups
77 username wheel dialout
78
79 gclib can now connect to serial and usb devices from user *username*.
80
81 ##PCI Controllers
82 If using a Galil PCI controller, the PCI driver must be installed.
83
84 ###Install prerequisites
85
86 $ sudo yum install kernel-devel-$(uname -r)
87 $ sudo yum install kernel-headers-$(uname -r)
88 $ sudo yum install gcc
89
90 ###Extract source and build driver
91
92 $ tar -xf /usr/share/doc/gclib/src/gclib_pci.tar.gz
93 $ make
94
95 ###Copy module and add to kernel
96
97 $ sudo cp galilpci.ko /lib/modules/$(uname -r)
98 $ sudo depmod
99 $ sudo modprobe galilpci
100
101 ###Add galil group for access to PCI
102
103 $ sudo groupadd -f -K GID_MIN=100 -K GID_MAX=499 galil
104 $ sudo cp 90-galilpci.rules /etc/udev/rules.d/
105 $ sudo udevadm control --reload-rules
106 $ sudo udevadm trigger
107 $ sudo usermod -a -G galil username #exchange "username" with actual user's name
108
109 Logout and back in. The PCI hardware is now available for access.
110
111 $ ls -l /dev/galil*
112 crw-rw---- 1 root galil 10, 56 Jun 9 11:07 /dev/galilpci0
113 $ echo -e "\x12\x16\r" > /dev/galilpci0
114 $ cat /dev/galilpci0
