GNOME Commander

A powerful file manager for the GNOME desktop environment

Building a Gnome Commander RPM for CentOS 7 30 May 2019

Introduction

Gnome Commander is usually available from the nux-dextop repository. Until such time as GCMD version 1.10.2 is added (nux IS a volunteer effort) you can build your own rpm file to install or update GCMD on your CentOS 7 machines without installing all of the packages needed to build GCMD from source on each machine. This example assumes a CentOS 7 virtual machine is build to accomplish the task. VMWare Workstation/Player (the free for non-commercial use version) or Virtual Box should work fine. A development physical machine could also be installed or the necessary packages installed on an existing machine. The virtual machine approach just seems cleaner as it can be deleted or archived when the job is done.

Steps to build the VM

Install CentOS 7.6 Development and Creative Workstation from the installation DVD. Select these additional software groups:

After completing the installation, install all current updates and reboot the VM. A few additional packages are needed to build the .rpm package.

Steps to install Gnome Commander in CentOS

Add the CentOS SCl repository which provides the GCC version 8 compiler and then install the necessary packages:

    sudo yum install centos-release-scl
    sudo yum install devtoolset-8 libgnome-devel libgnomeui-devel
    sudo yum install rpmdevtools rpmlint exiv2-devel taglib-devel poppler-devel

If you desire to include the single instance option it is necessary to add the following package to the machine on which you are compiling the application: unique-dev (available in the epel repository). A new option will appear later on under Settings in Gnome Commander:

Multiple instances
     [X] Don't start a new instance

On a new installation this option is checked by default. If you are upgrading an existing installation from a .rpm package this option may be unchecked.

The next step is to obtain the Gnome Commander source code. It may be downloaded from the web site with a browser or if you prefer the command line:

    wget https://download.gnome.org/sources/gnome-commander/1.10/gnome-commander-1.10.2.tar.xz 

Extract the gnome-commander.spec file. This may be done with the archive manager in the GUI environment or by the command line

    tar -xvf gnome-commander-1.10.2.tar.xz gnome-commander-1.10.2/data/gnome-commander.spec

Edit the .spec file with your favorite editor and locate the line:

Epoch:         2

Change the 2 to 4. Scroll down to a block of lines which begin with “Requires:” and add a new line:

Requires:      gnome-icon-theme-legacy >= 3.0

Save the changes. Note: these changes should not be necessary in future versions of GCMD.

The next step is to create the necessary directory structure to build .rpm packages. The is done by executing:

   rpmdev-setuptree

Several directories will be created under the use home directory (~/)

rpmbuild
  BUILD
  BUILDROOT
  RPMS
  SOURCES
  SPECS
  SRPMS

Place the source code file (gnome-commander-1.10.2.tar.xz) in SOURCES and the gnome-commander.spec file in SPECS. Change directory to ~/rpmbuild/SPECS/ and issue the following commands:

   scl enable devtoolset-8 -- bash
   rpmbuild -ba gnome-commander.spec

After considerable processing a message containing “exit 0” should be displayed. Two shiny new .rpm files will be present in ~/rpmbuild/RPMS/x64_86/:

gnome-commander-1.10.2-1.el7.x86_64.rpm and gnome-commander-debuginfo-1.10.2-1.el7.x86_64.rpm

A few notes about using these RPM packages

It is necessary to access the epel repository in order to install these packages due to a dependency for the meld package. The epel repository may be disabled afterwards if desired. Install epel on each target machine as follows:

   sudo yum install epel-release

The newly created GCMD package can be installed with yum:

   sudo yum install gnome-commander-1.10.2-1.el7.x86_64.rpm 

If upgrading an existing GCMD installation prior to GCMD 1.10.1 it may be necessary to run the following command to accommodate preference changes in GCMD. Try running the newly installed GCMD from the command line with gnome-commander. If it fails to run and errors are displayed execute:

   sudo glib-compile-schemas /usr/share/glib-2.0/schemas

The new Gnome Commander icon should appear on the menu under “Accessories”.

Please feel free to communicate any questions, concerns or comments about these instructions to the Gnome Commander Mailing lists as described on the home page.
