1 # Red Hat 7 & CentOS 7 Linux {#rhel7}
5 This version of Linux has **x64/AMD64 Support Only**. Contact Galil if another version
6 is required for an application.
8 See the \link installation \endlink page for supported versions.
11 On Red Hat, gclib and \link gcaps \endlink are distributed in RPM repositories. The following steps can be performed to install.
13 ### Download Galil's repository information
15 Point a browser at http://www.galil.com/sw/pub/rhel/7/galilrpm-4-1.noarch.rpm and install the rpm.
16 This installs Galil's RPM repositories and can be done from the terminal with the following.
18 $ wget http://www.galil.com/sw/pub/rhel/7/galilrpm-4-1.noarch.rpm
19 # rpm -Uvh galilrpm-4-1.noarch.rpm
26 Approve "Installed size" and "Importing GPG key", if prompted.
28 #### Install gcaps (optional)
30 Following Linux's daemon naming conventions, gcaps is called *gcapsd* on Red Hat.
31 See the \link gcaps \endlink documentation for more information.
35 Verify that the systemd unit is running.
37 $ systemctl is-active gcapsd
40 ### Uninstall Packages
42 If the packages need to be removed from the system, the following commands may be used.
52 ##Serial Ports and USB
53 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.
55 ###Determine group with access
57 $ ls -l /dev/ttyUSB* /dev/ttyS*
58 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
59 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
60 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
61 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
62 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
64 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
66 ###Add the desired *username* to the group.
68 $ sudo gpasswd -a username dialout
69 [sudo] password for username:
70 Adding user username to group dialout
72 Log out and back in for change to take effect.
75 username wheel dialout
77 gclib can now connect to serial and usb devices from user *username*.
80 If using a Galil PCI controller, the PCI driver must be installed.
82 ###Install prerequisites
88 # yum install kernel-devel-$(uname -r)
89 # yum install kernel-headers-$(uname -r)
92 ###Extract source and build driver
94 $ tar -xf /usr/share/doc/gclib/src/gclib_pci.tar.gz
97 ###Copy module and add to kernel
99 # cp galilpci.ko /lib/modules/$(uname -r)
103 ###Add galil group for access to PCI
105 # groupadd -f -K GID_MIN=100 -K GID_MAX=499 galil
106 # cp 90-galilpci.rules /etc/udev/rules.d/
107 # udevadm control --reload-rules
109 # usermod -a -G galil username #exchange "username" with actual user's name
111 Logout and back in. The PCI hardware is now available for access.
114 crw-rw---- 1 root galil 10, 56 Jun 9 11:07 /dev/galilpci0
115 $ echo -e "\x12\x16\r" > /dev/galilpci0
