4 Initialization and Output Files

Autoconf-generated configure scripts need some information about how to initialize, such as how to find the package's source files and about the output files to produce. The following sections describe the initialization and the creation of output files.

• Initializing configure: Option processing etc.
• Versioning: Dealing with Autoconf versions
• Notices: Copyright, version numbers in configure
• Input: Where Autoconf should find files
• Output: Outputting results from the configuration
• Configuration Actions: Preparing the output based on results
• Configuration Files: Creating output files
• Makefile Substitutions: Using output variables in makefiles
• Configuration Headers: Creating a configuration header file
• Configuration Commands: Running arbitrary instantiation commands
• Configuration Links: Links depending on the configuration
• Subdirectories: Configuring independent packages together
• Default Prefix: Changing the default installation prefix
