  20 2. Building squashfs tools
  21 --------------------------
  22
  23 The squashfs-tools directory contains the source code for the Mksquashfs and
  24 Unsquashfs programs.  These can be compiled by typing make (or sudo make
  25 install to install in /usr/local/bin) within that directory.
  26
  27 2.1 Compressors supported
  28
  29 By default the Makefile is configured to build Mksquashfs and Unsquashfs
  30 with GZIP suppport.  Read the Makefile in squashfs-tools for instructions on
  31 building LZO, LZ4, XZ and ZSTD compression support.
  32
  33 2.2 Extended attribute support
  34
  35 By default the Makefile is configured to build Mksquashfs and Unsquashfs
  36 with extended attribute support.  Read the Makefile in squashfs-tools for
  37 instructions on how to disable extended attribute support, if not supported
  38 by your distribution/C library, or if it is not needed.
  39
  40 2.3 Reproducible builds
  41
  42 By default the Makefile is configured to build Mksquashfs with reproducible
  43 output as default.  Read the Makefile in squashfs-tools for instructions
  44 on how to disable reproducible output as default if desired.
