[lxc-devel] [PATCH 00/21] Enable building with bionic (Android C library)

[Stéphane Graber]

The following changes allow for LXC to be built on bionic using the
Android NDK.

The code has been test built with both eglibc and bionic and builds cleanly.
I unfortunately can't test the resulting Android binaries myself, so hopefully
someone can.

Quite a few of those changes is simple detection of missing functions and
updates to LXC to avoid using those features (capability, personality).

Some compatibility code was also added for openpty and mntent, those files are
based on the eglibc implementation of those functions and are only used when on
a libc implementation that doesn't have those functions.

This also does a bit of cleaning up of configure.ac.


Stéphane Graber (21):
  configure.ac: Add code to detect bionic C library
  configure.ac: Cleanup, comments, indent, ...
  Replace all reference to ushort by unsigned short
  Support both getline and fgetln
  No need to link against rt and util on bionic
  Replace get_current_dir_name by getcwd
  Add/remove extra includes
  conf.c: Define LO_FLAGS_AUTOCLEAR if it's not
  clone: Support bionic's clone() defintion
  tty.h: Ship our own minimal openpty.h
  Don't hard depend on capability.h and libcap
  personality.h: Make the personality code optional
  Workaround missing functions in other libc
  Make utmpx.h optional
  Add a bionic_alphasort function on bionic
  Replace strdupa call by standard strdup
  caps.h: Rename __errno to ___errno
  Add local implementation of mntent.h
  conf.c: Cleanup __S_ISTYPE
  lxc_unshare: Replace getpw*_r by getpw*
  utmp.c: Avoid duplicate definition of __USE_GNU
