/opt/fil

My favorite way to install Fil-C is the /opt/fil distribution, which places a Fil-C slice into the /opt/filc prefix. This includes a memory-safe OpenSSH client and server as well as many other useful programs compiled with Fil-C. In this world:

• The compiler is /opt/fil/bin/filcc and /opt/fil/bin/fil++. These are symlinks to /opt/fil/bin/filcc-clang-20.

• Fil-C system headers are in /opt/fil/include.

• All of the compiler's headers are in /opt/fil/lib/clang/20/include.

• Fil-C libraries are in /opt/fil/lib.

• Fil-C programs use /opt/fil/etc for configuration files.

• Programs compiled with Fil-C are in /opt/fil/bin and /opt/fil/sbin. This includes:

  • GNU bash
  • GNU coreutils
  • GNU binutils
  • Mg text editor
  • Compression utilities
  • OpenSSL library
  • OpenSSH client and server.

Additionally, /opt/fil/bin/pkgconf knows about the packages available in /opt/fil.

This allows Fil-C libraries and programs to coexist with non-Fil-C libraries and programs on any modern Linux distribution. Segregating Fil-C libraries and binaries into a separate directory structure avoids ABI compatibility problems. The Fil-C compiler is smart enough to know that if it finds itself installed in /opt/fil/bin, then it should:

• Use /opt/fil/include and /opt/fil/lib/clang/20/include for headers.
• Use /opt/fil/lib for libraries and CRT object files.
• Use /opt/fil/bin/ld as its linker.

The alternatives to /opt/fil are the pizfix slice and the Pizlix Linux distribution.
