I want to get the message from a Lora communication (which is in a .iq file), by using GNU-Radio but when i try to use one of the "Lora" block i have an error "AttributeError: module 'lora' has no attribute 'lora_receiver'".
I run GNU-Radio 3.8.1.0 in a VM (DragonOS_focal_R22.1) where gr-lora is already installed.
Here is some screen of my blocks and the error :
Any ideas ?

I'm trying to use Material Custom Component and also using some other components. But I have version conflict Uncaught DOMException.
Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': the name "mwc-icon" has already been used with this registry.
Currently, I'm using the yarn package manager to handle custom-component versions.
Somewhere in your code, you're trying to register the same custom element more than once. Maybe you're importing a library twice?
Recently iam trying to update my angular project from 8 to 9. While updating i also updated wijmo from wijmo/wijmo to #grapecity/wijmo package as it supports IVY.
But after the completing the upgradation, i can able to compile the application but i am getting the following error at run time
global-error-handler.service.ts:43 Error: Uncaught (in promise): TypeError: (0 , t[n]) is not a function
TypeError: (0 , t[n]) is not a function

I'd like to get some more info about this error. The quick thing to check is property initialization order. In Ivy, the properties are interpreted as they are specified in markup (previously wijmo controlled how they were interpreted). So you can break components by setting certain properties before others.
For example, if I tried to set the selectedIndex on a combobox BEFORE I set the data source, then the app would break at runtime because there are no items in the list to select yet.
More info here: https://www.grapecity.com/wijmo/docs/GettingStarted/Angular-Components#property-initialization-order-in-angular-9-ivy-and-higher
The next thing to check is component decorators (if you are inheriting our components). There are some breaking changes in decorators in Ivy.
For example, you might need to add {descendants: true} to ContentChildren queries.
Or you might need to add an #Injectable decorator to your class.
You can read more about breaking changes in Ivy and how to fix them here: https://angular.io/guide/ivy-compatibility-examples

I just started using feathers-blob for uploading files from a angular4 client using dropzone.
I followed the example but made an explicit service for the upload not tu blur up the app.js.
It compiles without error, but on execution i receive the following error, even i do NOT use multipart portion:
Info: error:
system/file-upload - Method: create: Cannot read property 'startsWith'
of undefined error: TypeError: Cannot read property 'startsWith' of
undefined

I also made sure to use the same versions of feathers-blob and dauria and multer as in the sample and not the newer ones from the npm. Result is the same.
What am i doing wrong? Any help appreciated. Thanks
If you look into dauria's code you'll see where the problem comes from:
Dauria.prototype.parseDataURI = function(dataURI){
if(!( dataURI.startsWith('data:') )) throw new Error(
this.errors.MISSING_PREFIX
);
Which means that somehow the value that you pass to the caller dauria.parseDataURI(yourDataVariable) - the yourDataVariable value does not start with 'data:'.
I made a test on Node and I had the same error while trying to upload an image. I solved it by adding the string "data:image/jpeg;base64" followed by the 64 encoded image.
Flash exceptions can provide: code,stacktrace, message and parameters.
I.e. ( from Here: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/runtimeErrors.html)
#2121 Security sandbox violation: %1: %2 cannot access %3. This may be worked around by calling Security.allowDomain.
In standard flash player (Not debug) normally i see just error code.
I can configure: -compiler.verbose-stacktraces=true to see the stacktrace.
Can I somehow get the arguments as well?
(%1, %2, %3)
Property "message" of the Error object will return a text description of the error. The only way to read parameters is to parse a text description.
I'm trying to run my Game created using cocos2d-x-v2.2.3 (language cpp) for windows phone. But it shows following error.
error C2440: 'type cast' : cannot convert from 'void (__cdecl StartScene::* )(void)' to 'cocos2d::extension::SEL_CCControlHandler'
If I include pch.h file in all class file above error is removed then new error created. The error is
"Cannot open include file: 'pch.h': No such file or directory"
Though pch.h and pch.cpp are presented in CocosDenshion. In this circumstances what should i do?
Thanks in Advance
i think this because you use wrong function, fowllow this (CCObject::SEL_CCControlHandler)(CCObject, CCControlEvent) so the func you use must have func(CCObject*, CCControlEvent),
