I am trying to port XMP toolkit over to android device. I was able to build xmpcore successfully, and have a libXMPCore.so. When I try to make libXMPFile.so using ndk-build, I am running couple of problems I don't understand.
1) Seems like libXMPFile.so is depended on libXMPCore.so. I managed to include libXMPCore.so in the Android.mk for libXMPFiles. My Android.mk looks like this:

However, when I tried to run ndk-build, it complains link errors such as:
WXMPFiles.o: in function WXMPFiles_GetXMP_1:/home/w18656/workspace/xline2/main-jb-qcpro-4.2-xl ine/motorola/hal/ispbypass/xmp/XMP-Toolkit-SDK-CS6/XMPFiles/jni/../sou rce/WXMPFiles.cpp:288: error: undefined reference to 'TXMPMeta<std::basic_string<char, std::char_traits<char>, std::allocator<char> > >::TXMPMeta(__XMPMeta__*)'
I am pretty confused as for TXMPMeta class implementation. Seems like the definations are in TXMPMeta.hpp, and implmentation of the class in the client-glue/TXMPMeta.incl_cpp.
However, I checked the XMPFiles.mak, and TXMPMeta.incl_cpp is not one of file we compile. How do we compile the implemenation of class TXMPMeta in? (Same issues with other TXMPxxx.incl_cpp)
I am using 8e android NDK, and trying to build a native shared lib for XMPCore and XMPFiles.
Thanks for all your help.
