Re: Cross compile problem - glib and libiconv

[Tommy Tam <ttam aerio com>]

Someone has told me how to work around the problem.  Just want to put this 
back to the post.

In the file configure, you can remove the lines that generates the 
error.  In this case,

if test "x$found_iconv" = "xno" ; then
   { { echo "$as_me:$LINENO: error: *** No iconv() implementation
found in C library or libiconv" >&5
echo "$as_me: error: *** No iconv() implementation found in C library
or libiconv" >&2;}
# new line:
    }
# old line, commented out:
#   { (exit 1); exit 1; }; }

This prevents configure from aborting.  You also need to make sure the path 
is defined for your newly compiled libiconv library before you run 
configure for glib.  Like:

CPPFLAGS="-I/your/path/libiconv/include"
LDFLAGS="-L/your/path/libiconv/lib"
export CPPFLAGS LDFLAGS

I'm able to cross-compile now, but don't have the hardware to test yet so 
not sure if everything is correct.
