   1 The common case
   2
   3         ./autogen.sh && ./configure && make
   4
   5         If something fails read the last lines. Typical reason to
   6         fail is a missing dependency, such as libtool or gettext.
   7
   8 Autotools
   9
  10         `./autogen.sh' generates all files needed to compile
  11         and install the code (run it after checkout from git)
  12
  13         `make distclean' removes all unnecessary files, but the
  14         code can still be recompiled with "./configure; make"
  15
  16         `make dist-gzip' (or -bzip2) creates a tarball that can
  17         be configured and compiled without running `./autogen.sh'

  19 Compiling
  20
  21         Use SUID_CFLAGS and SUID_LDFLAGS when you want to define
  22         special compiler options for typical suid programs, for
  23         example:
  24
  25         ./configure SUID_CFLAGS="-fpie" SUID_LDFLAGS="-pie"
  26
  27         The SUID_* feature is currently supported for chfn, chsh,
  28         newgrp, su, write, mount, and umount.
  29
  30         Use DAEMON_CFLAGS and DAEMON_LDFLAGS when you want to define
  31         special compiler options for daemons; supported for uuidd.
  32
  33         Use SOLIB_CFLAGS and SOLIB_LDFLAGS when you want to define
  34         special compiler options for shared libraries; supported for
  35         libmount, libblkid and libuuid.
  36
  37         FIXME: add notes about klib and uClib.

  40 Compile certain portion
  41
  42         See ./configure --help and use --disable-* and --enable-* options.
  43
  44         It's also possible to disable all the programs and enable only wanted.
  45         For example:
  46
  47         ./configure --disable-all-programs --enable-fallocate
  48
  49         Note that the configure script tracks dependencies between libs and
  50         tools. Always see warning messages and follow error messages if any
  51         dependence is necessary. For example to compile mount(8) you need also
  52         libmount, libblkid and libuuid:
  53
  54         ./configure --disable-all-programs --enable-mount --enable-libmount \
  55                     --enable-libblkid --enable-libuuid
  56
  57
  58 Static linking
  59
  60         Use --enable-static-programs[=LIST] configure option when
  61         you want to use statically linked programs.
  62
  63         Note, mount(8) uses get{pw,gr}nam() and getpwuid()
  64         functions for translation from username and groupname to
  65         UID and GID. These functions could be implemented by
  66         dynamically loaded independent modules (NSS) in your libc
  67         (e.g. glibc). These modules are not statically linked to
  68         mount(8) and mount.static is still using dlopen() like
  69         dynamically linked version.
  70
  71         The translation won't work in environment where NSS
  72         modules are not installed.
  73
  74         For example normal system (NSS modules are available):
  75
  76                 # ./mount.static -v -f -n -ouid=kzak /mnt/foo
  77                 LABEL=/mnt/foo on /mnt/foo type vfat (rw,uid=500)
  78                                                          ^^^^^^^
  79         and without NSS modules:
  80
  81                 # chroot . ./mount.static -v -f -n -ouid=kzak /mnt/win
  82                 LABEL=/mnt/win on /mnt/win type vfat (rw,uid=kzak)
  83                                                          ^^^^^^^^
