Chapter 1. Setting up a development workstation

Procedure

1. Install the git package:

   # dnf install git

   Copy to Clipboard

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

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

   Copy to Clipboard

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

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

   $ git config --global core.editor command

   Copy to Clipboard

   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:

   # dnf group install "Development Tools"

   Copy to Clipboard

2. Install the LLVM-based toolchain including the clang compiler and the lld linker:

   # dnf install llvm-toolset

   Copy to Clipboard

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

   # dnf install gcc-gfortran

   Copy to Clipboard

Procedure

1. Install the tools for debugging:

   # dnf install gdb valgrind systemtap ltrace strace

   Copy to Clipboard

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

   # dnf install dnf-utils

   Copy to Clipboard

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

   # stap-prep

   Copy to Clipboard

   Note that stap-prep installs packages relevant to the currently running kernel, which might not be the same as the installed kernel. 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:

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

   Copy to Clipboard

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

   # stap-prep

   Copy to Clipboard

   Note that stap-prep installs packages relevant to the currently running kernel, which might not be the same as the installed kernel. 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.

   # systemctl enable pmcd && systemctl start pmcd
