android_external_libiconv | Android port of GNU libiconv

As usual for GNU packages:. After installing GNU libiconv for the first time, it is recommended to recompile and reinstall GNU gettext, so that it can take advantage of libiconv. On systems other than GNU/Linux, the iconv program will be internationalized only if GNU gettext has been built and installed before GNU libiconv. This means that the first time GNU libiconv is installed, we have a circular dependency between the GNU libiconv and GNU gettext packages, which can be resolved by building and installing either.
first libiconv, then gettext, then libiconv again, or (on systems supporting shared libraries, excluding AIX)
first gettext, then libiconv, then gettext again. Recall that before building a package for the second time, you need to erase the traces of the first build by running "make distclean".
The library mode. This works on all systems, and uses a library libiconv.so' and a header file <iconv.h>'. (Both are installed through "make install".) To use it, simply #include <iconv.h> and use the functions. To use it in an autoconfiguring package: If you don't use automake, append m4/iconv.m4 to your aclocal.m4 file. If you do use automake, add m4/iconv.m4 to your m4 macro repository. Add to the link command line of libraries and executables that use the functions the placeholder @LIBICONV@ (or, if using libtool for the link, @LTLIBICONV@). If you use automake, the right place for these additions are the *_LDADD variables. Note that 'iconv.m4' is also part of the GNU gettext package, which installs it in /usr/local/share/aclocal/iconv.m4.
The libc plug/override mode. This works on GNU/Linux, Solaris and OSF/1 systems only. It is a way to get good iconv support without having glibc-2.1. It installs a library `preloadable_libiconv.so'. This library can be used with LD_PRELOAD, to override the iconv* functions present in the C library. On GNU/Linux and Solaris: $ export LD_PRELOAD=/usr/local/lib/preloadable_libiconv.so On OSF/1: $ export _RLD_LIST=/usr/local/lib/preloadable_libiconv.so:DEFAULT A program's source need not be modified, the program need not even be recompiled. Just set the LD_PRELOAD environment variable, that's it!
