1 # Red Hat & CentOS Linux {#redhat}
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 is distributed in an RPM repository. The following steps can be performed to install gclib.
13 ### Download Galil's repository information
15 This step installs Galil's RPM repositories and only needs to be done once.
18 * **Red Hat 7 and CentOS 7**
19 * Point a browser at http://www.galil.com/sw/pub/rhel/7/galilrpm-2-1.noarch.rpm and install the rpm.
21 * **Red Hat 6 and CentOS 6**
22 * Point a browser at http://www.galil.com/sw/pub/rhel/6/galilrpm-2-1.noarch.rpm and install the rpm.
24 <!--- $ sudo wget http://www.galil.com/sw/pub/rhel/galil.repo -O /etc/yum.repos.d/galil.repo -->
27 Install gclib package, approve "Installed size" and "Importing GPG key", if prompted.
29 $ sudo yum install gclib
34 $ sudo yum remove gclib
37 * The gclib shared object files
38 * /usr/lib/libgclibo.so
39 * /usr/lib/libgclib.so
40 * The gclib header files
41 * /usr/include/gclib_errors.h
42 * /usr/include/gclibo.h
43 * /usr/include/gclib.h
44 * /usr/include/gclib_record.h
45 * gclib documentation tarball
46 * /usr/share/doc/gclib/gclib_129_doc.tar.gz
47 * Example source tarball
48 * /usr/share/doc/gclib/src/gclib_129_examples.tar.gz
49 * Source files to modify/rebuild libgclibo.so
50 * /usr/share/doc/gclib/src/gclibo_129_src.tar.gz
51 * GalilTools Communication Library (gcl) wrapper
52 * /usr/share/doc/gclib/src/gclib_129_gcl.tar.gz
54 * /usr/share/doc/gclib/src/gclib_129_pci.tar.gz
56 ##Serial Ports and USB
57 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.
59 ###Determine group with access
61 $ ls -l /dev/ttyUSB* /dev/ttyS*
62 crw-rw----. 1 root dialout 4, 64 Mar 3 16:39 /dev/ttyS0
63 crw-rw----. 1 root dialout 4, 65 Mar 3 16:39 /dev/ttyS1
64 crw-rw----. 1 root dialout 4, 66 Mar 3 16:39 /dev/ttyS2
65 crw-rw----. 1 root dialout 4, 67 Mar 3 16:39 /dev/ttyS3
66 crw-rw----. 1 root dialout 188, 0 Mar 6 11:08 /dev/ttyUSB0
68 In the above listing, **dialout** is the group that needs to be joined. **uucp** is another common group that may be listed.
70 ###Add the desired *username* to the group.
72 $ sudo gpasswd -a username dialout
73 [sudo] password for username:
74 Adding user username to group dialout
76 Log out and back in for change to take effect.
79 username wheel dialout
81 gclib can now connect to serial and usb devices from user *username*.
84 If using a Galil PCI controller, the PCI driver must be installed.
86 ###Install prerequisites
88 $ sudo yum install kernel-devel-$(uname -r)
89 $ sudo yum install kernel-headers-$(uname -r)
90 $ sudo yum install gcc
92 ###Extract source and build driver
94 $ tar -xf /usr/share/doc/gclib/src/gclib_202_pci.tar.gz
97 ###Copy module and add to kernel
99 $ sudo cp galilpci.ko /lib/modules/$(uname -r)
101 $ sudo modprobe galilpci
103 ###Add galil group for access to PCI
105 $ sudo groupadd -f -K GID_MIN=100 -K GID_MAX=499 galil
106 $ sudo cp 90-galilpci.rules /etc/udev/rules.d/
107 $ sudo udevadm control --reload-rules
108 $ sudo udevadm trigger
109 $ sudo 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
121 The documentation is left as a tarball to minimize disk usage. The latest release version of the user manual is available at the following link.
122 * http://www.galil.com/sw/pub/all/doc/gclib/html/
125 The following allows viewing of the html docs from the installation.
127 $ tar -xzf /usr/share/doc/gclib/gclib_132_doc.tar.gz html
128 $ firefox html/index.html
131 There may be a pdf shipped in the package. The following allows viewing of the pdf docs from the installation.
133 $ tar -xzf /usr/share/doc/gclib/gclib_132_doc.tar.gz gclib_132.pdf
