[CRIU] Android cross-compilation

[Domenico Iezzi]

Hi everyone,

I want to ask you if it's possible to cross-compile criu for android 
(arm-linux-androideabi).

I am trying to cross-compile it with the android ndk, following the 
instructions both on the wiki and on github. For the ndk, I'm using the 
script 'make_standalone_toolchain.sh' inside the build/tools folder, 
which prepares an environment similar to the linaro toolchain, but the 
compilation results in some errors related to redefined or non-existant 
variables, like this:

   CC       compel/plugins/std/std.o
   CC       compel/plugins/std/fds.o
In file included from compel/plugins/std/fds.c:10:0:

  #define __section(S)  __attribute__ ((__section__(#S)))

   PBCC     images/autofs.pb-c.c

Can you point me in the right direction? Here [0] are the file I use to 
cross-compile.

Many thanks
