I have installed geany and also have MinGW compiler. I am trying to print a simple "hello" but unable to do so. I have saved my file in the name of print.c.
The error that I am getting- .\print is not recognized as an internal or external command.
below I have attached the need:

I have a small C console program and I want to add an .ico file to it, so that the executable looks nice.
How can I do this in CodeBlocks with MinGW/gcc?
I could not find relevant help via google that a total beginner (like me for C) could follow, so I will Q&A this topic.
First of all you need an .ico file. Put it in the folder with your main.c file.
In CodeBlocks go to File -> New -> Empty File and name it icon.rc. It has to be visible in the Workspace/Project otherwise CodeBlocks will not be aware of this file. It will show up there in a project folder called Resources .
Put the following line in it: MAINICON ICON "filename.ico". MAINICON is just an identifier, you can choose something different. More info 1 & More info 2.
Save the files and compile - CodeBlocks will do everything else for you
What will happen now, is windres.exe (the Resource Compiler) compiling the resource script icon.rc and the icon to an object binary file to obj\Release\icon.res. And the linker will add it to the executable.
It's so easy yet it took me quite a while to find it out - I hope I can save someone else having the same problem some time.
This is my hello world program. It compiles, but when I Run it says :
"Source file not compiled"
I have included header files stdio.h and conio.h.
Any solution.? I installed code::blocks as well, I got a similar error in that IDE as well.
int main()
{
printf("Hello world");
return 0;
}
As it compiles, it is generating an exe file, which is not showing up in command prompt, it is somehow getting deleted(may be McAfee is doing it)
Specify path into the path variable...u can get your path variable into control panel ...if ur file successfully compiled ...means there is no error ..OK ...then if u run ur program then ur CPP file path should be set into path variable same like as java..
Are you making a C or C++ program? Include a header file that references iostream also.
What happens is that the .c files are not printing well to Eclipse's console.
printfs() print to console like they should but errors are not being showed.
I've tried:
-Go to Window->Preferences->Run/Debug->Console the option "Show when program writes to standard error" is toggled on.
My OP is Linux Cinnamon 32-bit.
Note: If I use the terminal it shows the errors of the program in question.
In my current example, I have a C file called 'Main.c' which converts and prints US pounds into UK stones/UK pounds/kilos, and the variable US pounds is currently defined by the user's input (scanf). The file itself is executed through Visual Express 2013; however, I want to change this so that I can navigate to the C file and execute the file directly through the commmand prompt (cmd) whiles passing a value to define US pounds.
I understand that this is required in main:
void main(int argc, char *argv[])
And I know how to navigate to the C file through the command prompt:
>cd Directory/To/The/File
However this is where I get stuck; I don't know how to execute the C file. I have researched into this and found several examples, such as using 'gcc' and 'cc', but the system doesn't recognise these commands. None of the materials that I have found fully explains what exactly I have to do in order to accomplish what I am trying to do; do I have to install something, or am I using the wrong commands, is it possible what I am trying to do, what excactly do I have to do?
Broadly speaking, you need to do the following:
Compile the program using a compiler to generate an executable.
Run the executable file.
When you "run the program in Visual Studio", it is doing all of those steps for you.
I don't know much about command line compiling in Windows, but I believe msbuild is the name of the compiler which Visual Studio uses. Look into that, and you'll see how to compile. Compilation will then generate the executable, which you just type into the command line to run.
EDIT: I found an article which suggests that cl is a C compiler command available on the command line.
Here is the relevant excerpt:
At the command prompt, specify the cl command together with the name of your source file—for example, cl simple.c—and press Enter to compile the program. The cl.exe compiler generates an .obj file that contains the compiled code, and then runs the linker to build an executable program that has the name of your source file, but has an .exe file name extension—for example, Simple.exe.
You cannot cd to the file, only to the directory. The cd command means "change directory".
You cannot execute a C file, it's just a text file and your computer doesn't know how to run it. You need to compile it first (this is what Visual Studio does). There should be an EXE file somewhere close, you need to find it. It is the binary, executable, form of your C program which you can run directly from the command line.
Before moving on to question, I'm 100% newbie to programming and I'm on my own.
So please answer my question even though you think it seems very silly.
Somehow I manage to install command line tools successfully:
LazyRen:~ LazyRen$ xcode-select -p
/Applications/Xcode.app/Contents/Developer
LazyRen:~ LazyRen$ xcode-select --install
xcode-select: note: install requested for command line developer tools
LazyRen:~ LazyRen$ gcc
clang: error: no input files
But the problem is when I tried to build the most basic codes with ST3 it gives me
clang: error: no input files
[Finished in 0.0s with exit code 1]
[cmd: ['gcc', 'Hello C World!', '-o', 'Hello C World!']]
[dir: /Users/LazyRen/Library/Application Support/Sublime Text 3/Packages/User]
[path: /usr/bin:/bin:/usr/sbin:/sbin]
This.
I just have no idea what kind of input file is needed. Any hints?
You appear to be lost inside ST3. As you have Xcode why not use it instead? To run a command line "Hello World" C program do the following:
Open Xcode
Select File > New > Project...
On the left side select Application under OS X
On the right select Command Line Tool
Press Next
Fill the 3 text fields with "hello" "LazyRen" & "com.lazyren" - these at not important in this situation, but the Next button won't be enabled till you fill them in.
In the Type menu select C
Press Next
In the standard save dialog locate the folder you wish to store your code in and then press Create
Project will now open in Xcode, select main.c on the left. On doing that the large editing area will show the starting template - which just happens to be "Hello World!"
Select Product > Run - you've run your first command line C program. Output will appear in a small window.
Now continue with your C textbook. Also look at the Xcode documentation. In the latter you will find out how to locate the code you just compiled on the disc to you can run it from Terminal if you wish.
