Marble on android compilation problem

[Jean GUARDIA]

Many thanks Dennis, for your response.
As I need really,really quick this, I managed to compile marble. 
Here what i have done to make it work. It is absolutely ugly but it worked
for me.

In the NDK, i link every x86 folders as if they where arm. and link every 
compiler files as if they were arm. Then I compile and it produces the build 
with no more errors. I know it's really ugly, bad, and dirty ...
I do this because it was the mess and whatever parameter I give, compiler or 
libs were not found.
In a later mail, i will give you all the tests i've made
One more time, thank you for your support and your quick response.

Sincerely yours.  Jean Guardia
