I'm trying to run a simple c++ program that open a window using the SFML library in Xcode 13
#include <iostream>
#include <SFML/Window.hpp>
int main(int argc, const char * argv[]) {
sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");
return 0;
}
When i try to run it under native arm64 at compile time show this error:
Undefined symbols for architecture arm64:
"sf::String::String(char const*, std::__1::locale const&)", referenced from:
_main in main.o
"sf::Window::Window(sf::VideoMode, sf::String const&, unsigned int, sf::ContextSettings const&)", referenced from:

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
And when I try to run it under rosetta (x86_64) show this:
Undefined symbols for architecture x86_64:

Idk what to do, I'm new to c++. THANKS

I am trying to compile this code mentioned below.
#include "Poco/Net/HTTPRequest.h"
#include "Poco/Net/HTTPResponse.h"
#include "Poco/Net/HTTPMessage.h"
#include "Poco/Net/WebSocket.h"
#include "Poco/Net/HTTPClientSession.h"
#include <iostream>
using Poco::Net::HTTPClientSession;
using Poco::Net::HTTPRequest;
using Poco::Net::HTTPResponse;
using Poco::Net::HTTPMessage;
using Poco::Net::WebSocket;
int main(int args,char **argv)
{
HTTPClientSession cs("echo.websocket.org",80);
HTTPRequest request(HTTPRequest::HTTP_GET, "/?encoding=text",HTTPMessage::HTTP_1_1);

try {

char *testStr="Hello echo websocket!";
char receiveBuff[256];
int len=m_psock->sendFrame(testStr,strlen(testStr),WebSocket::FRAME_TEXT);
std::cout << "Sent bytes " << len << std::endl;
int flags=0;
int rlen=m_psock->receiveFrame(receiveBuff,256,flags);

std::cout << receiveBuff << std::endl;
m_psock->close();
} catch (std::exception &e) {
std::cout << "Exception " << e.what();
}
but it is not compiling in terminal even though i installed the poco libraries in my PC by using the following commands:
$ git clone -b master https://github.com/pocoproject/poco.git
$ cd poco
$ mkdir cmake-build
$ cd cmake-build
$ cmake ..
$ cmake --build . --config Release
$ cmake .. -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=/path/to/mytoolchain.cmake -DCMAKE_INSTALL_PREFIX=/path/to/target
$ sudo cmake --build . --target install
The default install location is /usr/local/ on Linux and macOS and C:\Program Files (x64)\ on Windows and can be overridden by setting the CMAKE_INSTALL_PREFIX CMake variable.
here are the errors showing after compiling it with this command in terminal::-->g++ -Wall -std=c++11 EchoRequest.cpp -o echo
where EchoRequest.cpp is the file name and echo is the i mentioned for compiled file
Here are errors showing-->

any help me out with this error. I checked in online it is showing the solutions for cpp IDE's and afterr exploring I got to know it is a OS error so what to do to rectify this error.
can anyone suggest a command line for compiling it properly or any required changes that must be need to do it as per the OS.
please help me out if anyone knows the answers
I followed the instruction on thier github https://github.com/openvinotoolkit/openvino to build it on macOS, done it and when i wrote a small code to check was all clear or not

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Did anyone had the same problem as me, and did anyone know how to fix it?
First and foremost just need to cross check with you on your toolkit installation. Since you are trying to run a model already, I assume you already set it up properly as in (fyi latest version is 2020.4): https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_macos.html
The error that you are getting, the Undefined symbols for architecture x86_64 is an Xcode build failure indicating you missed out something in your inference engine or the way you link the model with certain resources are incorrect or some other reasons. As long as this error persist you won't be able to compile your code. That is why you got the linker command failed with exit code 1.
Most error occurs because the users did not Set the OpenVINO environment variables or Configure the Model Optimizer correctly. This is why it's really important to Run verification scripts to verify installation and compile samples.
Before running any custom model, it is good to have a solid working Openvino environment, hence please help to check whether you could run the default models as in example here https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_macos.html
By default, you should already have pre-trained models including open zoo model, Model Optimizer and Inference Engine which are working example to work with if you configured the toolkit correctly. These should already located in your installed toolkit's directory which you don't have to install separately from other resources.
Please take a note that you need:
CMake 3.4 or higher,
Python 3.5 or higher,
Apple Xcode Command Line Tools*,
(Optional) Apple Xcode* IDE (not required for OpenVINO, but useful for development),
And supported MAC OS is macOS 10.14.4*
Again, please help to cross check what you have in your Openvino environment and steps you had used to configure with the official documentation https://docs.openvinotoolkit.org/latest/openvino_docs_install_guides_installing_openvino_macos.html
Thanks!

As it stands your program does not have a main function. If you compile it, the linker will complain about the absence of a main function. Since you are writing unit tests using the catch framework, you want that framework to generate a main function for you.
The catch framework looks whether CATCH_CONFIG_MAIN is defined and if yes, it generates a main function for you which runs all the tests you define. Because compilation is a linear process, the macro CATCH_CONFIG_MAIN has to be defined before including catch.hpp. Otherwise, the library will never “see” this macro.
#define CATCH_CONFIG_MAIN
#include "catch.hpp"
TEST_CASE("CATCH TEST"){
REQUIRE(1 == 1);
}
Live example
I'm building a big project related to a simulation of a detector in physics.
I have to compile the project using CMAKE on macOS Sierra 10.12.5 and my processor architecture is 64-bits.
I built all the requirement programs using "homebrew".
I tried to compile in different CMAKE architecture modes:
cmake ../mu3e
cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 ../mu3e
cmake -DCMAKE_OSX_ARCHITECTURES=i386 ../mu3e
cmake -DCMAKE_OSX_ARCHITECTURES="ppc;i386" ../mu3e
cmake -DCMAKE_OSX_ARCHITECTURES="x86_64;i386" ../mu3e
../mu3e is the directory of the source.
I always ended up with the same or similar error regarding the "Undefined symbols for architecture x86_64:" and "ld: symbol(s) not found for architecture x86_64":

Thank you for any possible advice and please let me know if you need further information.
I'm new to c++, so sorry if there is an obvious solution I'm missing. I'm trying to run this example code for dlib in c++. I'm getting this error...

#error "Also make sure you have libx11-dev installed on your system"
I've tried going into /dlib/CMakeLists.txt and adding
set(DLIB_NO_GUI_SUPPORT OFF)
I know it's found the X11 package as I'm not getting a message from the cmake there (and I just installed XQuartz)
Also, I'm using Clion, so I'm not running cmake from the command line. And I'm on OSX
Edit: I tried removing the parts of the code that use the gui, just to see if it would work. But I then get this error:

I think this is a separate issue from the first one, but idk, maybe they are related? For this issue, I've tried doing what was mentioned here https://github.com/davisking/dlib/issues/57 I made the link for the first part, then added these lines to my cmakelist.txt
include_directories(../../../../usr/X11/lib)
include_directories(../../../../usr/local/include)
include_directories(../../../../usr/local/lib)
Didn't seem to fix the issue though.
Edit 2: So I think both these issues are resolved now. I think added those include_directories lines that I mentioned above help. Also, I started using cmake from the command line, instead of with clion.
However, I am now getting a new error :/

One issue after another :/
Edit 3: Success! So I was using Clion for compiling. Even though the cmake from clion is the same version as the cmake I'm using in the command line, it just didn't work for some reason.
I solved this by deleting the "cmake-build-debug" directory.
Then reopen the project(CLion will regenerate it).
It seems there remain some cache files would affect the compiling.
But before this step, please make sure you do install XQuartz.
