saving the file first fixed it

RynEllis · May 17, 2019, 5:10pm

I got the program to compile. Simple program with clear instructions.

KnitterX · May 18, 2019, 2:08pm

When I try to compile the code for the first time it seems to compile but I get a warning.
When I try to run the exe it says access denied and my antivirus software gives me a warning and deletes the exe.
When I try to compile again it doesn’t work anymore and I get a Linker error “LINK : fatal error LNK1104: cannot open file ‘hello.exe’”

Does anyone know how to get this to work?
Thanks

compilation went ok, but afterwards i am not able to delete the .exe file! (win 10) it says access denied. i have to ask user (my own admin user i am logged in as) for permission… no way to authenticate again…

i am now unable to get rid of the file…

Welcome @Bitefish and @KnitterX to the community!

Danielle_H · May 26, 2019, 12:57am

I had no problem compiling.

Nanta · May 26, 2019, 7:14am

pretty sure that’s because it’s using normal windows console not developer console Don’t remember how I fixed it but it’s not hard

Nanta · May 26, 2019, 7:33am

It seems to work now except that I got the warning C4530 I just have no idea why it works now

(Edit
actually now I know why it works I added Windows 10 SDK both of them since I did add one before but it didn’t fix it
)

#include <iostream>

int main()
{
    std::cout << "Hello World!\n";
    return 0;
}

also I added Hello world there

KnitterX · May 27, 2019, 7:47pm

No, it was the right console. The problem was that my anti virus software was blocking it.
I had to add the project folder to the exceptions.

Jamie_Greenaway · May 29, 2019, 12:01am

When I am trying to compile I keep on getting the error message
“LINK : fatal error LNK1104: cannot open file ‘kernel32.lib’”
Does anyone know what is wrong?

nannakaroliina · June 4, 2019, 6:04pm

Yes, I was able to compile it!

WestCoastal · June 4, 2019, 8:48pm

Hello @Jamie_Greenaway , I think I am getting a similar error as you.
Using VS Code on windows 10 64. Please see the screenshot. Any help?

Saif_Almzrouei · June 6, 2019, 1:35pm

I’m using Mac and the
g++ hello.cpp -o hello
and then
./ hello
part didn’t work for me. anyone know why?

Jamie_Greenaway · June 7, 2019, 10:51pm

Yeah that’s the exact same error

iamaryanyadav · June 8, 2019, 3:04pm

No, I was not able to compile. When I entered “cl hello.cpp” it came in the terminal " ‘cl’ is not recognized as an internal or external command, operable program or batch file."
How do I resolve this?

Tanya613 · June 9, 2019, 3:02pm

Yep, got hello.cpp to compile. Because I had VS 2017 Enterprise installed, I had to find the 2019 command prompt, and then followed the prefernces>settings>shell, and included the line to find the buildtools cmd.

Mabkhout_alameri · June 10, 2019, 11:30am

hello there … i satrted new here but i got an error
“LINK : fatal error LNK1181: cannot open input file”. . how can i fix it … its in the compilar in VS code

TrafficProducer · June 10, 2019, 11:36am

Hello word First COMPLETE Begigner test

rob_mcq · June 11, 2019, 1:49am

I was not able to do it. When I press enter windows appears asking which app I want to use to open the hello.cpp file. I did chose Visual Studio Code… now when I type hello.cpp I just get a new line of my directory where hello.cpp is. sorry if its a silly question
