I added the .so to LDConfig following this article. Still getting the following. You can get the source for the code here. Here is the log from the startup of the binary.

I am completely stumped. Any ideas as to whats going wrong?
FYI, I am invoking the following C# code:
[DllImport("libWinsockLib", CallingConvention = CallingConvention.Cdecl, EntryPoint = "dllInit")]
public static extern Double dllInit();
Finally, I used the following build commands to build the 39dll-4-linux project:
Executed for each .cpp file:
g++ -fPIC -c -o obj/<filename>.o <filename>.cpp
Then I executed:
ld -G obj/*.o -o 39dll4linux.so
Never mind! I figured it out. Turns out, ld is not a good way to package and link a shared library.
Instead of the ld command, i used:
g++ -shared obj/*.o -o 39dll-4-linux.so
It works like a charm!

I want to use:
co_await winrt::resume_foreground(window.DispatcherQueue());
(Type of "window" is: "winrt::Microsoft::UI::Xaml::Window")
But I cannot compile it because
winrt::resume_foreground(Microsoft::System::DispatcherQueue const& dispatcher)
is not defined.
I cannot include #include <winrt/Microsoft.System.h> which contains the DispatcherQueue class.
My environment:
Windows 10 Pro, 21H1, 19043.1083
Visual Studio Community 2019 (16.10.3)
Visual Studio Extension: Project Reunion Version 0.8.0.46122163
Project Template: C++, Blank App, Packaged (WinUI 3 in Desktop)
To reproduce the error I used the Project Template above and added the following method to the "App" class.
App.xaml.h
winrt::Windows::Foundation::IAsyncAction foo();
App.xaml.cpp
winrt::Windows::Foundation::IAsyncAction App::foo()
{
co_await winrt::resume_foreground(window.DispatcherQueue());
}
I get the error message:

Include
#include <winrt/Microsoft.UI.Dispatching.h>
#include <Microsoft.UI.Dispatching.co_await.h>
When updating from 0.8.0 preview to 0.8.0 there was a namespace change from
Microsoft.System to Microsoft.UI.Dispatching and resume_foreground is now defined in Microsoft.UI.Dispatching.co_await.h.
The answer from Markus does not work for me in the WinUI3 1.0 release because the Microsoft.UI.Dispatching.co_await.h header file does not exist. However, the following does work:
#include <wil/cppwinrt.h>
#include <wil/cppwinrt_helpers.h>
co_await wil::resume_foreground(DispatcherQueue());
My team and I are building gRPC using CMake. We have been building gRPC v1.26 (and v1.23 too) just fine with CMake 3.15.6, but since CMake 3.16.x is not building anymore.
This is the log of the tools we are using:

The only thing changed between working build and not working one is: removing build folder, uninstall CMake 3.15.x, reboot, install CMake 3.16.0, build grpc all over again.
Anyone faced something like this? Thank you
I think, I may have improperly set up cmake wrong,(or improperly set up cmake for that matter) or I'm bad and rusty at C++ or both and possibly more. I just want to add a header and separate code into a class that loads images for opengl. I also put them in another directory parallel to other libraries in my linux file tree.
The main project folder has the main cmakelists.text file in it it's called "maficengine". Inside it are also a "build" file a "common" file and "external" file and a file called "Mafic", "maficGuiSourceFiles" file and one called "distrib." I think we can just focus on 2. "mafic" and "external". Inside mafic I have one called mafic.cpp which has my main function and is the entry point. Inside external, there is another folder called "myCustomHeaders".. therein lies a file called "loadTexture.cpp" It contains the loadTexture class declaration and definition. Also inside "myCustomHeaders" there is an "include" file which contains "loadTexture.h"... I cannot seem to instanciate an instance of LoadTexture lt; and call the function of loadtexture(); I expect it to at line 187 in mafic.cpp

here's mafic.cpp
#include <loadTexture.h>
int main( void )

lt.loadtexture();
}
here's my loadTexture.cpp
class loadTexture
{
public:
loadTexture();
~loadTexture();
void loadtexture(){
fprintf(stdout, "loadtexture does something, that's a positive result for this test");
}
};
and finally my loadTexture.h
[code]
#pragma once
#include <GL/glew.h>
//GLuint image;
void loadtexture();
[/code]
Hoping it would build with no errors but I get ...

I use QT 5.1.1 and Qt Creator 2.8.1
I want use printer:
QPrinter printer(QPrinter::HighResolution);
QPrintDialog printdialog(&printer,this);
if (printdialog.exec() == QDialog::Accepted)
{
QTextDocument doc;
doc.setHtml(s);
doc.print(&printer);
}
And I get this error:
DictionaryWidget.obj:-1: error: LNK2019: unresolved external symbol "__declspec(dllimport) public: _thiscall QPrinter::QPrinter(enum QPrinter::PrinterMode)" (_imp_??0QPrinter##QAE#W4PrinterMode#0##Z) referenced in function "private: void __thiscall DictionaryWidget::on_pbPrint_clicked(void)" (?on_pbPrint_clicked#DictionaryWidget##AAEXXZ)
in .pro file I have:
QT += core gui xml printsupport
to build Environment in QT Creator LIBPATH as follows:
libpath: C:\Windows\Microsoft.NET\Framework64\v4.0.30319;C:\Windows\Microsoft.NET\Framework64\v3.5;C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\LIB\amd64;C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\ATLMFC\LIB\amd64;C:\Program Files (x86)\Windows Kits\8.0\References\CommonConfiguration\Neutral;C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0\ExtensionSDKs\Microsoft.VCLibs\11.0\References\CommonConfiguration\neutral;C:\Qt\5.1.1\msvc2012\lib;
In the folder C:\Qt\5.1.1\msvc2012\lib file is located Qt5PrintSupport.lib
What should I do to make the project work?
i encounter an error like

Error Message is
Error 1 fatal error LNK1107: invalid or corrupt file: cannot read at 0x2C8 C:\Program Files\OpenCV\bin\highgui110.dll 1 OpenCV Capture
What wrong with highgui.dll ?
Please help.
Thanks.
This is my source code.
Code:
#ifndef CAM_CAPTURE_H
#define CAM_CAPTURE_H
#include "cv.h"
#include "highgui.h"
class CamCapture
{
private:
CvCapture* myCaptureHandler;
IplImage* videoFrame;
int key;
public:
CamCapture();
~CamCapture();
void Init();
};
#endif
Remove highgui110.dll from your list of Additional dependencies. In additional dependencies you should list only lib files.
