Chapter 1. Setting up a development workstation

Procedure

1. Install the git package:

   # yum install git

2. Optional: Set the full name associated with your Git commits:

   $ git config --global user.name "Full Name"

3. Optional: Set the email address associated with your Git commits:

   $ git config --global user.email "email@example.com"

   Replace Full Name and email@example.com with your actual name and email address.

4. Optional: To change the default text editor started by Git, set value of the core.editor configuration option:

   $ git config --global core.editor command

   Replace command with the command to be used to start the selected text editor.

Procedure

1. Install the Development Tools package group including GNU Compiler Collection (GCC), GNU Debugger (GDB), and other development tools:

   # yum group install "Development Tools"

2. Install the LLVM-based toolchain including the clang compiler and lldb debugger:

   # yum install llvm-toolset

3. Optional: For Fortran dependencies, install the GNU Fortran compiler:

   # yum install gcc-gfortran

Procedure

1. Install the tools useful for debugging:

   # yum install gdb valgrind systemtap ltrace strace

2. Install the yum-utils package in order to use the debuginfo-install tool:

   # yum install yum-utils

3. Run a SystemTap helper script for setting up the environment.

   # stap-prep

   Note that stap-prep installs packages relevant to the currently running kernel, which might not be the same as the actually installed kernel(s). To ensure stap-prep installs the correct kernel-debuginfo and kernel-headers packages, double-check the current kernel version by using the uname -r command and reboot your system if necessary.

4. Make sure SELinux policies allow the relevant applications to run not only normally, but in the debugging situations, too. For more information, see Using SELinux.

Procedure

1. Install the tools for performance measurement:

   # yum install perf papi pcp-zeroconf valgrind strace sysstat systemtap

2. Run a SystemTap helper script for setting up the environment.

   # stap-prep

   Note that stap-prep installs packages relevant to the currently running kernel, which might not be the same as the actually installed kernel(s). To ensure stap-prep installs the correct kernel-debuginfo and kernel-headers packages, double-check the current kernel version by using the uname -r command and reboot your system if necessary.

3. Enable the Performance Co-Pilot (PCP) collector service:

   # systemctl enable pmcd

4. Start the Performance Co-Pilot (PCP) collector service:

   # systemctl start pmcd
