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 am new to c language and I am trying to compile my first program, following a tutorial.
My file hello.c :
#include <stdio.h>
int main(void)
{
printf("hello, world\n");
}
I use "make hello" command to compile it but I get the error:
cc hello.c -o hello
process_begin: CreateProcess(NULL, cc hello.c -o hello, ...) failed.
make (e=2): The system cannot find the file specified.
<builtin>: recipe for target 'hello' failed
make: *** [hello] Error 2
I have MinGW installed and I have it in my environment variables PATH.
I am trying it on Windows 8.
Please any help I would very appreciate.
Maybe there is another way to compile a c files?
MinGW is actually a gcc compiler. So the C compiler is invoked with gcc instead of cc. Try running this command:
make hello CC=gcc
[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.
I am learning C and I have a simple hello world program that I am trying to run on Windows 10. Here is the code:
#include <stdio.h>
int main() {
printf("Hello, world!\n");
return 0;
}
I have installed GCC compiler and I tried the following in order to run it in the command prompt:
gcc hello.c
a
I also tried:
gcc hello.c
./a.exe
and:
gcc hello.c
./a
and:
gcc hello.c -o hello
./hello
The program does not run displaying hello, world and it gives the following error:
bash: a.exe: command not found
What am I doing wrong and how can I run the program after the compilation?
It appears that your compilation succeeded successfully.
See if there is an a.out or a.exe file present, as you didn't indicate a non-default executable name.
Note that running a alone typically won't do anything, because it is highly unlikely that your executable is on the bash PATH. This means you need to run ./a.out or ./a (depending on base operating system).
Binary executables under windows typically must have .exe extension to be recognized as such.
I am not sure if gcc under windows adds the right extension automaticaly when outputting executables.
I would try:
gcc hello.c -o hello.exe
./hello.exe
I've watched tons of videos about how to use sublime text 3 I do what they say but it doesn't work. When i type "subl test.c" in terminal it opens up a a file called test.c in sublime text 3 when i use the command gcc -c test.c everything is fine too, but when I try to run the code using ./test it says bash: ./test: No such file or directory
Bash says that there is no such file or directory because you haven't created a file called 'test'. You should specify an output filename, i.e. you should type gcc test.c -o your_out_filename. Then you may run your program using ./your_out_filename. Without -o flag gcc will create a a.out by default, so your out_filename will be a.out.
You have to use the following command to create a file called test:
gcc test.c -o test
If you don't use the -o option (gcc test.c) your created file will be a.out.
The option -c of gcc only compiles your file and doesn't link it to a program which you can run. The result of the -c option is only an object file called test.o.
Therefore the easiest way is the one I have mentionend above (-o option).
You have to run:
gcc -o output test.c
output is the file you have to do ./output in terminal for it to execute
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
