I have some source codes from a friend that I would like to use as referenced library in my BlackBerry project. I'm not sure about how to package the source codes into a .jar file. I tried exporting the source to a JAR file and import it as external JAR in my project, it's giving me missing stack map error. I tried to preverify the .jar file generated from the source using the provided preverification tool from BlackBerry JDE, it didn't give me any output folder.
In fact, I'm not sure if the way I export the source is correct. Can anyone provide step-by-step instructions on how to package existing source code into a valid JAR file that can be imported into my project as a referenced library?
Again, I'm using eclipse.
I fought with this issue for months...
I have two solutions for you:
A-If you plan on having this library in more than one Application:
I posted my solution at the bottom of my original question: Blackberry Apps - Importing a code-signed jar into an application project
The basic solution was to build the library as a cldc project (plus some other magic), not as a library project. I actually had to open a case with RIM support to figure this out, it was a hot mess... Our case was complicated in that more than one application would have a copy of our "Library" and our library had to be signed. Which caused weird issues when two ALX files (from two different apps) both had the same signed library file.
The nice thing about this solution is that adding the library to the Application doesn't force you to have multiple COD files.
B - If your Jar is only going to be in one Application:
Then you should follow these instructions: http://supportforums.blackberry.com/t5/Java-Development/Eclipse-1-1-can-I-add-external-3-d-party-JAR-library/m-p/486787#M98033

I must have read over a dozen posts on possible techniques to link a local library into my Swift Package. Specifically, my package depends on libturbojpeg.a, which most users won't have installed anywhere. Even if they did install it (there is a DMG), I'd have to go through hoops to make sure I was linking in the correct version. I finally found a post in the Swift Forums that basically says you can't do it now.
It appears that the only way to link it now is using .linkerSettings(LinkerSetting.unsafeFlags(..., but if you use that your package can't be managed by Xcode (see above link, and I even tried it and verified it cannot be used).
Is there some kind of workaround that allows me to distribute my Swift Package with the library?
In my Package, I created a directory "Libraries" and added my library there.
I discovered that Xcode 11 places included Swift Packages in a specific location in the Derived Folders directory. This means that it is possible to tell Xcode where to find it during the link phase.
My Package has these instructions in it for users:
1) Add the Package using Xcode->File->Packages with the URL of https://github.com/dhoerl/
2) Open the app's Project Build Phases, and from the Package shown in the left file pane, drag the Libraries/.a file into the link phase. It will appear just above the that should already be there
3) In Application Build settings, under library search paths, add:
"$(BUILD_DIR)/../../SourcePackages/checkouts//Libraries"
Build and run! Voíla - works like a charm!
Note: obviously this is somewhat fragile, Xcode 12 could change how packages are managed, but its possible by then that the Swift Package Manager will support linking of local libraries (its mentioned in the above link.)
we want to create a MobFox-Plugin for our hybrid apps. It is already running well in CLI-Cordova Apps, but it does not work in our hybrid apps, because it seems that the directory structure of the framework (the symbolic links between headers and version directory) is destroyed by Windows, where the framework is inside the plugin in the mda project. If I start a build, the header directory of is not recognized as a symbolic link, but as an ordinary executable textfile on the Mac.
This is how I include the framework in the plugin xml:
<framework src="libs/ios/MobFox.framework" custom="true"/>
I also tried to copy the MobFox.framework to the SDK Frameworks Folder and reference it like the standard system libraries (which work well):
<framework src="MobFox.framework" />
But this also fails, though the Framework is now included correctly in Xcode. But the compiler now says that it cannot find the MobFox.h-class, this is how it's included:
#import <MobFox/MobFox.h>
So I really think that the problem is that Windows cannot handle the symbolic links inside the .framework File. Does anybody has a workaround or solution for this problem? Or an idea why my Workaround with placing the file in the Standard-Frameworks Folder does not work?
Any help would be highly appreciated.
Thanks
Same problem here - it appears that when the plugin is published to the cordova registry it loses the symbolic links inside the .Framework package that tell XCode where everything is.
They are maintained on git, so it is something in the plugman export/publish that is going wrong.
So for example
cordova plugin add https://github.com/uxcam/cordova-uxcam
will work for the plugin I am writing, but not
cordova plugin add com.uxcam.cordova.plugin
which is the published version.
If you delve down into the 'plugins' folder of the project you added it too and 'show package contents' on the com.uxcam.cordova.plugin file you can then get into 'src/ios'UXCam.framework' and see how it has messed up the symbolic links in the framework folder that should point at the Headers folder and a link the the library binary as well.
Reference: Cordova bug report here: https://issues.apache.org/jira/browse/CB-6092
Update: I've worked around the problem by manually putting files in the framework into the places they need to be. So now on the github project I reference above you can see that the framework library is directly in the UXCam.framework folder, and there is an explicit Headers folder that has the UXCam.h file in it. This works for a published plugin now.
Not an ideal solution and every time I update the framework I'll have to fix the layout again, but works for now until I can find the proper place to report the problem.
I've been playing around with the Starter Edition of Xamarin Studio to determine if it will meet my needs. I understand (so I thought) the limitations of this edition; 32K compiled IL limit, no native libraries, etc. Now, I understand native libraries to be C/C++ libraries, or even native Java libraries. This does not seem to be the case.
I have a solution in Xamarin Studio with 2 projects. One is an Android Class Library, the other is an Android Application. When I reference the class library from the application project and build, I get the following error.
Your app references native libraries. This functionality requires Indie Edition or higher.
I beg to differ! Every .cs file in the referenced Android class library project is simple .NET code. What am I missing? I can successfully run the Tasky Android_Starter solution without issue, and it is made up of 2 projects like mine.
I had to delete the Resources folder and manually edit the Android class library project file in order to get this working. I looked at the Tasky sample's project file as a reference.
After deleting the auto-included Resources folder from the project, edit the .csproj file in a text editor to remove the following XML elements:
Project\ProjectGroup\AndroidResgenFile
Project\ProjectGroup\AndroidResgenClass
With those things taken care of, I no longer get the error. I'm guessing, Xamarin Studio thought I was referencing another Android application instead of a class library. Not sure why the default project template includes things to break such a flow, but perhaps I'm not "doing" right" either. Go figure.
Deleting the Resources folder and manually editing the csproj file didn't work for me. I had to create a new C# Library project instead of creating an Android Library Project and import my .cs files into that. After that it compiled and ran fine.
here I have just started my fyp and ints gona be in opencv.
I needed to vectorize the image and in order to do that I chose to use cvblobslib.
I downloaded it and it was build successfully but when I use it in my project there's a link error saying that "could not open cvblobslib.obj"
the exact string is pasted below
fatal error LNK1104: cannot open file 'E:\Faizan\myWork\moCap\blobslib\Debug\cvblobslib.obj'
of the solutions which I found on net and tried on my project are to remove any spaces in path, build in release mode rather than in debug mode, but problem was not solved.
the thing is that the stated file does not get built with other files when cvblobslib is built, i.e it is not there in the stated folder.
any body please give a solution
What exactly are you trying to use the cvblobslib for? I also tried using this with no luck. I found that openCV has a lot of the same capabilities. For example, you can use cvCountours to detect "blobs" and filter them by area.
(ps. i tried leaving this as a comment. do you need certain amount of rep to do that?)
cvBlobsLib has been developed using Microsoft Visual C++ (6.0) and can also be used in .NET. A Linux version could be downloaded here.
cvBlobsLib is distributed in a static library (.lib). To use it, it is requred that you build the .lib file and later use that lib file in the desired project. To build the .lib file, simply open the MSVC++ project and build it (debug or release version).
To build the project where the library is to be used follow this steps (MSVC++ 6.0):
In Project/Settings/C++/Preprocessor/Additional Include directories add the directory where the blob library is stored
In Project/Settings/Link/Input/Additional library path add the directory where the blob library is stored and in Object/Library modules add the cvblobslib.lib file
Include the file BlobResult.h where you want to use blob variables.
In Project/Settings/C++/Precompiled Headers select Not use precompiled headers
NOTE: Verify that in the project where the cvblobslib.lib is used, the MFC Runtime Libraries are not mixed:
Check in Project->Settings->C/C++->Code Generation->Use run-time library of your project and set it to
Debug Multithreaded DLL (debug version) or to Multithreaded DLL ( release version ).
Check in "Project->Settings->General" how it uses the MFC. It should be "Use MFC in a shared DLL".
NOTE: The library can be compiled and used in .NET using this steps, but the menu options may differ a little
NOTE 2: In the .NET version, the character sets must be equal in the .lib and in the project. [OpenCV yahoo group: Msg 35500]
NOTE 3: cvBlobsLib might give errors when building with OpenCV v2.2 onwards. Try commenting out this line in file BlobLibraryConfiguration.h:
#define _SHOW_ERRORS
NOTE 4: If you are using the new cv::Mat for your images instead of the old IplImage, you can easily convert between them, such as by following the OpenCV C++ Cheatsheet.
i a developing blackberry aplication using eclipse can any one tell where to find the following library
package com.rim.samples.docs.notifications;
i have downloaded it from blackberry site but i dont know how to use it
com.rim.samples.docs namespace is common for samples BlackBerry Application Developer Guide.
On the other hand, "package" token defines the packege namespace, not the import.
If you have downloaded code and post it to namespace with other name, you may have trouble to compile it. Resolve it in two ways:
1. if your code file is placed directly in project src folder, simply remove
package com.rim.samples.docs.notifications;
from code, this will set namespace to default.
2. in project src folder create folder "com\rim\samples\docs\notifications" and move file to folder "notifications".
