The Wonderful toolchain lives in /opt/wonderful. Tools should avoid hardcoding that path, instead relying on the WONDERFUL_TOOLCHAIN environment variable.

The hierarchy of folders in the toolchain's directory is arranged as follows:

• bin - Toolchain-wide binaries; most of them are prefixed with wf-, so this directory should be safe to add to PATH without conflict.
• doc - Per-package documentation.
  • <package name>
• etc - Toolchain-wide configuration.
• lib - Toolchain-wide libraries.
• pacman - wf-pacman package manager state (cache, database, et cetera).
• share - Only used by wf-pacman's makepkg. (TODO: This is probably a good idea to merge with lib)
• tmp - Temporary files.

There are also per-target/per-toolchain folders:

• examples - Target-specific examples.
  • <target>
• target - Target-specific library and include files.
  • <target>
    • include
    • lib
    • …
• templates - Target-specific project templates.
  • <target>
    • <template>
• toolchain - Toolchain-specific binary and library files.
  • <toolchain>

Third-party projects packaged within wf-pacman (say, by using their own repository) should use their own subdirectory:

• thirdparty
  • …

Third-party code packaged outside of wf-pacman (say, provided by the user) should use the local subdirectory:

• local
  • …
