BUILDING:
In order to install build dependencies on Debian / Ubuntu do the following:
sudo apt-get install build-essential git pkg-config -y
sudo apt-get install libtracefs-dev libtraceevent-dev -y
In order to install build dependencies on Fedora, as root do the following:
dnf install gcc make git pkg-config -y
dnf install libtracefs-devel libtraceevent-devel -y
In case your distribution does not have the required libtracefs and
libtraceevent libraries, build and install them manually:
git clone https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git/
cd libtraceevent
make
sudo make install
git clone https://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git/
cd libtracefs
make
sudo make install
To make trace-cmd
make
To make the gui
make gui
INSTALL:
To install trace-cmd
make install
To install the gui
make install_gui
To install libtracecmd libraries
make install_libs
Note: The default install is relative to /usr/local
The default install directory is /usr/local/bin
The default plugin directory is /usr/local/lib/trace-cmd/plugins
To change the default, you can set 'prefix', eg
mkdir $HOME/test-trace
make prefix=$HOME/test-trace
make prefix=$HOME/test-trace install
