With any luck, you're using a modern, package-based operating system
that has all of these packages available in the distribution. In that
On Debian and similar systems:
- sudo apt-get install libtalloc-dev libelf-dev
+ sudo apt-get install libtalloc-dev libelf-dev \\
+ libgl1-mesa-dev
Or on Fedora and similar systems:
- sudo yum install libtalloc-devel libelf-devel
+ sudo yum install libtalloc-devel libelf-devel \\
+ mesa-libGL-devel
On other systems, similar commands can be used, but the details of the
package names may be different.
