10 ##Installation
11 On Red Hat, gclib is distributed in an RPM repository. The following steps can be performed to install gclib.
12
13 ### Download Galil's repository information
14
15 This step installs Galil's RPM repositories and only needs to be done once.
16
17 Point a browser at http://www.galil.com/sw/pub/rhel/6/galilrpm-2-1.noarch.rpm and install the rpm.
18
19 ### Install Package
20 Install gclib package, approve "Installed size" and "Importing GPG key", if prompted.
21
22 # yum install gclib
23
24 ### Uninstall Package
25 To uninstall gclib.
26
27 # yum remove gclib
28
29
30 ##Serial Ports and USB
31 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.
32
33 ###Determine group with access
34
35 $ ls -l /dev/ttyUSB* /dev/ttyS*
36 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
37 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
38 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
39 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
40 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
41
42 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
43
44 ###Add the desired *username* to the group.
45
46 $ sudo gpasswd -a username dialout
47 [sudo] password for username:
48 Adding user username to group dialout
49
50 Log out and back in for change to take effect.
51
52 $ groups
53 username wheel dialout
54
55 gclib can now connect to serial and usb devices from user *username*.
56
57 ##PCI Controllers
58 If using a Galil PCI controller, the PCI driver must be installed.
59
60 ###Install prerequisites
61
62 # yum update kernel
63
64 ####Reboot
65
66 # yum install kernel-devel-$(uname -r)
67 # yum install kernel-headers-$(uname -r)
68 # yum install gcc
69
70 ###Extract source and build driver
71
72 $ tar -xf /usr/share/doc/gclib/src/gclib_pci.tar.gz
73 $ make
74
75 ###Copy module and add to kernel
76
77 # cp galilpci.ko /lib/modules/$(uname -r)
78 # depmod
79 # modprobe galilpci
80
81 ###Add galil group for access to PCI
82
83 # groupadd -f -K GID_MIN=100 -K GID_MAX=499 galil
84 # cp 90-galilpci.rules /etc/udev/rules.d/
85 # udevadm control --reload-rules
86 # udevadm trigger
87 # usermod -a -G galil username #exchange "username" with actual user's name
88
89 Logout and back in. The PCI hardware is now available for access.
90
91 $ ls -l /dev/galil*
92 crw-rw---- 1 root galil 10, 56 Jun 9 11:07 /dev/galilpci0
93 $ echo -e "\x12\x16\r" > /dev/galilpci0
94 $ cat /dev/galilpci0
