Hi again
Followup! OK. I have solved a problem.
Bunch of leads/links compiled together read twice forward and backward
and the devil is in the detail...
Most of the stuff can be done according to:
http://docs.xamarin.com/ios/Guides/Advanced_Topics/Native_Interop
Only in the part for Linking:
http://docs.xamarin.com/ios/Guides/Advanced_Topics/Native_Interop#Linking_Your_Library
it is important to add that configuration of mtouch tool for linking
with extra arguments for gcc
[-cxx] -gcc_flags "-L${ProjectDir} -lMylibrary -lSystemLibrary
-framework CFNetwork -force_load ${ProjectDir}/libMyLibrary.a"
[-cxx] optional - for c++ only
******* makes exported symbols internal **************, so DllImport
should look like:
[DllImport("__Internal")]
happy hollidays

Hi
I'm trying to bind with PInvoke native c++ library for iPad. The
library is a part of the bigger project
and is ported from Windows Mobile to iOS (iPad to be more precise).
The c++ code was fixed to compile
with g++ in MonoDevelop and those *.h and *.cpp files were added to
Xcode project which compiled.
In the next step small shell script did shared libs for iOS (x86
simulator and arm7 for iPad) together with
fat lib. Library is added in the root of the MonoTouch project as
content and with property copy to output dir
for PInvoke. The app ran on 2 Macs, but had problems DLL not found
exception on third Mac - and this one
had break on all exceptions turned on.
Further investigation (adding -v -Wall options in mtouch Extra
arguments for gcc) showed that mtouch
does not copy this static lib to temp folder. ld and collect scream
that file is not found.
As a test I took a lib from monotouch-samples and could bind it, but
this is objective-c.
What could cause mtouch not to copy .a file to tmp folder (/var....)
during linking
thanks in advance
Merry Christmas to all

More details:
1. c++ library ported from WinCE
2. c++ fixes for g++ with MonoDevelop
3. Xode project creaed after fixes - compiles OK.
4. script that builds static libraries + fat library
5. PInvoke
[DllImport("libiPadNative.a")]
public static extern void RotateFromToIntAccHelper16BitZoom(short*
srcPointer, int srcWidth, int srcHeight, int srcOriginX, int srcOriginY,
6. mtouch options
-cxx -gcc_flags "-v -Wall -L${ProjectDir} -liPadNative -force_load
${ProjectDir}/libiPadNative.a"
NOTE: added -v -Wall to get more verbose output.
7. in MD - Excepion only if break on all Exceptions is enabled
System.DllNotFoundException has been thrown
System.DllNotFoundException: libiPadNative.a

8. Added LinkWith atribute
-> does not compile (link errors)
-> Liker errors
[assembly: LinkWith ("libiPadNative.a", LinkTarget.Simulator |
LinkTarget.ArmV6 | LinkTarget.ArmV7, ForceLoad = true)]
even w/o armv6
[assembly: LinkWith ("libiPadNative.a", LinkTarget.Simulator |
LinkTarget.ArmV7, ForceLoad = true)]
Just for test sake:
[assembly: LinkWith ("libXMBindingLibrarySampleUniversal.a",
LinkTarget.Simulator | LinkTarget.ArmV6 | LinkTarget.ArmV7, ForceLoad
= true)]
9. Build output -
