[Image][1]I am using an Ubuntu machine. I want to run C program on Visual Studio code. I have installed C/C++ extension and CODE RUNNER extension to my VS Code. But when I am going to run a simple program, it is showing me errors. What should I do now ?
tony#Jarvis:~/Desktop/c program$ cd "/home/tony/Desktop/c program/" &&
gcc Hello World.c -o Hello World && "/home/tony/Desktop/c program/"Hello World
gcc: error: Hello: No such file or directory
gcc: error: World.c: No such file or directory
gcc: error: World: No such file or directory
gcc: fatal error: no input files
compilation terminated.
Your file name should not contain any spaces. I see Hello World.c. This will not work. Try changing it to HelloWorld.c
Your file name has spaces, Hello World.c. Having spaces while using a Command Line too like gcc is not good. Stay away from spaces as much as you can. In this case gcc thinks that Hello and World.c are separate files.

Hello I have a project written in C that contains four .c files in different directories.These are ipv4_lib.c udp_lib.c projekt_C.c programLib.c
I 've written it in eclipse and everything works fine and it's easy to run,but now I have to run it in console.I have already run programs in console,but they were much easier and usually contained one or two headers in the same directory,so all I had to do was compile each files and run the main one.
But I have no idea how to run project.Is there some command to do that or something like that? Thanks
Look into GCC and Clang:
GCC: https://en.wikipedia.org/wiki/GNU_Compiler_Collection
Clang: https://en.wikipedia.org/wiki/Clang, https://clang.llvm.org/
Both are compilers you can use to compile your source code via the terminal. GCC is has been around longer and has better support but can be a little slow. Clang is newer, so less widely used, but is noticeably faster than GCC at compiling source code.
An example Clang command in your terminal:
clang -o hello hello.c && ./hello
This will compile your hello.c file and give you a hello executable that you can then run. We'll just assume that running the hello program prints Hello, World! to the console.
Trying to compile a source code written in C.
Location of the code is: C:\Users\Chris\Documents\prog\c\learn\GOODBYE.C
In CMD I typed the code: gcc goodbye.c -o goodbye
Got this error:
gcc: error: goodbye.c: No such file or directory
gcc: fatal error: no input files
compilation terminated.
I wanted the output to be named goodbye.
How do I fix this?
Make sure that you are running gcc goodbye.c -o goodbye while you are in the C:\Users\Chris\Documents\prog\c\learn\ directory.
If the c file is named GOODBYE.c then you should run gcc GOODBYE.c -o goodbye
Enter the name of the directory in which the program is located. Like if the program is in "D" drive, then open the VS Code terminal and enter "D:" (without quotation) and hit enter, and then rerun the code like this.
what if you run gcc "C:\Users\Chris\Documents\prog\c\learn\GOODBYE.C" -o goodbye
I guess it could be the case sensitivity. Either rename the file or run gcc GOODBYE.C -o goodbye
I'm trying to do some basic programs in C in NetBeans, it worked well yesterday but now it shows some errors that I can't get rid off. First one shows when I try to compile my main.c file via NetBeans's terminal. I have included 2 files: stdio.h and stdlib.h. They don't show errors in code (it's not highlighted with red underline), only when I try to compile it via terminal. But when I tried to compile file via windows's cmd, it worked. Second error shows when I run program in NetBeans.
1st error: bash-4.4$ gcc main.c -o nav1 main.c:13:19: fatal error: stdio.h: No such file or directory
2nd error: bash.exe: warning: could not find /tmp, please create!
My Ubuntu version is 14.04 LTS. I have a C program copied on the desktop by the name sendRawEth.c. When I write:
gcc sendRawEth.c -o sendRawEth
The compiler complains:
gcc: error: sendRawEth.c: No such file or directory
gcc: fatal error: no input files
I have no idea how to solve this error.
please do the following.
On terminal check the present directory by 'pwd' command and then check the directory in which your programme is there and see if they are same or not. And while writing gcc yourfile it's case sensitive. Hope this helps
There are 2 reasons for such errors.
You said you copied your C programs in your desktop folder.
This means you may have only copied sendRawEth.c. file format not the executable file.
You should ensure you copy the .exe files as well.
You need to change the directory to the same folder that you copied your programs into.
First, check your current folder by typing pwd.
Then change it to your required folder with:
cd /outerfolder/your program folder
Then compile it with:
gcc -o programname programname.c
And finally execute it with:
./programname
I'm trying to compile my first "Hello World" application using GCC (build-on clang and stand-alone GCC-4.9.2) without any success:
OS version is OS X Yosemite 10.10.2.
I'm using the following code (main.c):
#include <stdlib.h>
#include <stdio.h>
int main (){
printf("Hello World!");
getchar();
return 0;
}
Then I compile it in terminal with a command (clang shipped with XCode):
gcc -o hello -c main.c
As a result I got following error whe running compiled hello file:
MBP-Andrii:cTest andrii$ gcc -o hello -c main.c
MBP-Andrii:cTest andrii$ hello
-bash: /Users/andrii/avrTest/cTest/hello: Permission denied
If I change the permissions for hello file to 777 and a new error again:
MBP-Andrii:cTest andrii$ chmod 777 hello
MBP-Andrii:cTest andrii$ hello
Killed: 9
MBP-Andrii:cTest andrii$
The same thing happens with stand-alone GCC-4.9.2.
I guess It might be something related to the output binary format or some missing flags for compiler.
Remove the -c from the command you're using to compile the application.
The -c tells the compiler to only compile and assemble but not link. You are not actually creating an application when using -c.
See the GCC Manual:
-c
Compile or assemble the source files, but do not link. The linking stage simply is not done. The ultimate output is in the form of an object file for each source file.
By default, the object file name for a source file is made by replacing the suffix ‘.c’, ‘.i’, ‘.s’, etc., with ‘.o’.
Unrecognized input files, not requiring compilation or assembly, are ignored.
Try executing it by typing ./hello
