Compiling for Android

[beuc]

Hi,

Is there anybody working on compiling Guile for Android?

Here are some notes when trying to compile stable-2.0.

First important note: I had to move "AC_CHECK_LIB(m, cos)" (which btw
could be rewritten at LT_LIB_M()) before gl_INIT in configure.ac,
otherwise libunistring would fail to be detected.

The compilation fails when libgc tries to use pthread features not
implemented under Android (btw ./configure was happy to start
compiling even if libgc wasn't present).  Not sure where to go from
here, maybe other projects use libgc and already faced the issue?
Which version of libgc do you recommend?

Cheers!
Sylvain
