Hi,

I am a newbie in the Computer Vision field and I needed to build a marker-less ar app in windows phone which lead me to this impressive library. but I had two issues:

1- I am using visual studio, refering to libfastcvnative.lib that came with the FastCV windows phone SDK would gave me "unresolved externals" error when trying to use any of the FastCV functions. refering to the libfastcv.lib that came with the Android SDK (but under VS2012 folder) solved it. will this work fine for developing windows phone app or I am missing something?

(btw the download links have been giving me error from a couple of hours)

2- Do FastCV contain everything needed for the images recognition & trackig (i.e. can I rely on it?).because as I noted for example for the feature detection, FAST & Harris only supported with no support for the scale invariant algorithms that's important for the AR apps.

I hope I will be lucky enough to find some answers.

Hi,

Answer to query 1. Hi, as far as I can make out from your query, you are getting the error ""unresolved externals" while trying to include libfastcvnative.lib in your Visual Studio Project. These errors generally occur when you don't specify the path to the lib and to the includes(which come with the release package) propely. It's a standard proceedure and should be easy to do so. Please refer to the release notes for help. If you are still not able to resolve, then let me know. I will try to provide a further solution

Hi, I appretiate your help.

I did include the lib & include folders & I know it can find the library because changing the path would give the error :

Error 1 error LNK1104: cannot open file 'libfastcvnative.lib'

my problem is whenever I try to use any of the fastCV's functions it show me the "unresolved externals" error.

As a solution I am changing the path to the libfastcv.lib library that came with the Android SDK and it is working well but I am not sure if it is a right thing to do and whether it is gonna cause me any problems in the future.

thanks again for your help and I would be so grateful I can find an answer.

Hello!

I, too, have the same issue with 'unresolved externals' when referencing the FastCV libfastcvnative.lib. Trying to use libfastcv.lib that comes with the Android FastCV SDK does not help, since it comes with a whole bunch of new issues, most likely stemming from the fact that it wants older files (for example libcmtd.lib) than what come with VS 2013.

Any help is appreciated, preferably help that doesn't include 'should be easy' and then pointing to release notes.

Best regards,

Kristian

Hello,

I am trying to FastCV with win8phone too, and having some problems getting it setup. I am defining include and lib dirs. But after I try to compile the application, I get an error saying libcmt.lib cannot be opened. I searched for it and it is c standard lib with multithreading. Any case, shouldn't it be already in somewhere default?

I manually searched and found it in programfiles/visual studio 11/ vc/ lib dir, i can add this directory in linker options. But it doesnt feel quite right. Anyone stumbled onto something similar? By the way, I am using visual studio 2013 ultimate.

Thanks

Here's what I did to make it work:

New WP8-project, C++
From Build->Configuration manager, select ARM as your target platform
Then from Project->Properties
Configuration properties->linker->general, I added the libfastcvnative.lib folder to Additional library directories.

And in Linker->Input I added the following:
libfastcvnative.lib to Additional dependencies
ole32.lib;libcmt.lib;libcmtd.lib; to Ignore specific default libraries

It may or may not be required to set the previous settings for both debug and release builds.

For my case, ignoring libcmt.lib solved it. I am not sure about the exact functionality of it, and wonder if it may have other consequences. However, This is the best solution up to now I guess.

Hi,

Try The following settings:

1. Configuration properties:

Platform Toolset : WindowsApplicationForDrivers8.1

Target Windows Phone Version: 8.1

Build for Windows Phone : Yes

2. Library Directories :

$(WindowsPhoneSdkDir)\Lib\win8\um\arm\

$(LibraryPath)

3. Library WinRT Directories :

$(WindowsSDK_MetadataPath

4. Linker: Additional Library Directories: <Path to libfastcvnative.lib>

5. Linker: Additional Dependencies:

libfastcvnative.lib
msvcrt.lib
oleaut32.lib
xmllite.lib
user32.lib
Gdi32.Lib
mincore.lib

6. Linker :Ignore All Default Libraries : Yes

7. Linker: Ignore Specific Defalut Libraries : oldnames.lib;%(IgnoreSpecificDefaultLibraries)

These are the settingd that works for me. I hope this helps you too
