Ive downloaded a sample code from here, but when I try opening it using visual studio code, I keep getting the following error:
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation
I have tried using xCode but this time it wont open at all,
As it can be figured Im using a mac, with the m1 chip to be precise.
This is a picture of the error:
How do I go about fixing the issue?
One can modify the configuration of Visual Studio code to support multiple files (header(s) and cpp ) running simultaneously on Mac.
Step 1
On the Virtual studio menu bar select
->terminal->configure task->Select the first option(C_Cpp_Runner)
Step 2
Go ahead and open the file folder in VS Code ->cmd+O ->select the file folder (with cpp and header included.)
At this point try running the code, if the same error still persist then, do Cmd+shift+P and make sure the Auto-header extension is installed.
That's what helped fixing my issue, hope it can benefit someone else out there.

I keep getting the same error on a simple piece of code after I downloaded multiple compilers and added them to 'PATH' in windows settings
Error :
E:\Programs\sublimeProjects\helloWorld: file not recognized: File format not recognized
collect2.exe: error: ld returned 1 exit status
[Finished in 985ms]
I downloaded multiple compilers and added them to 'PATH' in windows settings
This is a very bad idea. You will run into a complete mess where parts of one compiler interfere with parts of the other compiler due to them all being on the PATH.
I would recommend to immediately remove all compilers from the PATH. Instead, what you should do is have a batch file or shell script that you run to set up the environment for just that window.
Some compiler installations come already set up this way (e.g. mingw-w64/MSYS2).
In SublimeText you can set it to use that batch file or script to set up the build environment, e.g. see https://gist.github.com/sagebind/9039773048a3900fa49a .
I'm trying to run my C++ program on my Macbook and I'm trying to run my program in VSCode by running the build task C/C++:clang++ build active file. However, every time I do this I get this error ld: can't open output file for writing: /Users/admin/first/first, errno=21 for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The terminal process terminated with exit code: 1
This appears to be a simple permission problem here:
ld: can't open output file for writing
The linker cannot write to the file specified.
Edit: As correctly pointed to by molbdnilo, the error 21 is EISDIR, which means the file you are trying to write to already exists as a directory. So ... just this folder? :)
Did you brew install any c++ tools? Sometimes that is the source of these issues. The program is trying to use native OS versions of things when it should use Homebrew's or vice versa.
*This is my first programming course in over 20 years, so I am basically clueless.
I am trying to complete the last project in the course which includes installing and configuring SDL. Right now all I have is the basic "Hello World" code. I get the error when I add #include .
When I installed SDL, I copied the SDL2 folder and the entire lib folder to MinGW-w64 - as instructed by a tutorial.
I have MinGW-w64 installed. Here is the build error:
C:/MinGW64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):crt0_c.c:(.text.startup+0x2e): undefined reference to `WinMain'
collect2.exe: error: ld returned 1 exit status
I've been googling for hours and cannot seem to find any help.*
Edit:
Thank you both so much for your quick responses.
Here is what I did in settings:
Do I need to put an 'l' in front of these items?
I got some help elsewhere and added #define SDL_MAIN_HANDLED. This allowed the project to build, but it still doesn't run. I get nothing at all when I try to run it. I tried calling SDL_GetError(), but still nothing.
also make sure your main has the following signature:
int main(int, char**) - SDL is pretty militant about it
I want to add Unity to an existing ios Project,I have matched all the configuration of the two project, and import the frameworks.
I set Other Linker Flags : -weak_framework; -weak-lSystem; CoreMotion. just like the Unity Project.
and the error is：
clang: error: no such file or directory: 'CoreMotion'
when I deleted "CoreMotion" in Other Linker Flags, error changes:
ld: framework not found -weak-lSystem
how to fix it?
I have found that the order of the flags are important
It should be in this order :
-weak_framework
CoreMotion
-weak-lSystem;
All,
I have downloaded a Sample Project for Audio conversion:
https://developer.apple.com/LIBRARY/IOS/samplecode/iPhoneExtAudioFileConvertTest/Introduction/Intro.html
I had to take away all CAXException codes and CADebugPrintf codes. But then when I was trying to call the ExtAudioFileConvert.cpp's DoConvertFile function, it shows
"_DoConvertFile", referenced from:
....
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Please help.
Followed this post to remove "Preprocessor Macros" Setting
iOS,CoreAudio: a strange 'CADebugPrintf.h: no such file or directory ... ' error
and followed this post to add a .mm file as C++ wrapper to call DoConvertFile
