Checking build dependencies
Note: make sure that you are in the build/ subdirectory of your source tree.
When ../configure is run without any arguments, it
checks whether your system has everything required for
compilation.
../configure
If any build dependency is missing, ../configure returns
with
ERROR: Please install required programs: foo
The following message is issued if you are missing programs that are only needed for building the documentation.
WARNING: Please consider installing optional programs: bar
If you intend to build the documentation locally, you need to install or update these programs accordingly.
Note: ../configure may fail to issue warnings for
certain documentation build requirements that are not met. If you
experience problems when building the documentation, you may need
to do a manual check; see Requirements for building documentation.
