How propertly add my program in C?

Open 0xor opened this issue 9 years ago • 2 comments

I'm search information, scripts, Makefiles. How create simple 'hello world' in C. How compiling it (parameters?) and on what enviroment, distribution.

I have only source code of my program. What next?

I'm not sure how this is related to Alpine. Are you asking how to get utilities for building C applications inside a Alpine Linux Docker container? Usually, a good place to start is the build-base package.

To create and compile a simple "Hello, World!" program in C, follow these steps:

  1. Create Your Source Code First, create a file with your C source code. Name it hello.c. Here’s a basic example:

c Copy code #include <stdio.h>

int main() { printf("Hello, World!\n"); return 0; } 2. Set Up Your Environment You need a C compiler. On most Unix-like systems (like Linux and macOS), you can use gcc. On Windows, you can use MinGW or Microsoft Visual Studio.

On Linux/macOS: Ensure gcc is installed. You can install it using your package manager:

sh Copy code

On Debian-based systems (e.g., Ubuntu)

sudo apt-get install gcc

On Red Hat-based systems (e.g., Fedora)

sudo dnf install gcc On Windows: You can use MinGW:

Download and install MinGW from MinGW's website. Add the bin directory (where gcc.exe is located) to your system PATH. 3. Compile the Program Open a terminal or command prompt and navigate to the directory containing your hello.c file.

On Linux/macOS: Use the following command to compile the code:

sh Copy code gcc -o hello hello.c gcc is the compiler. -o hello specifies the output file name. hello.c is your source file. This will generate an executable named hello.

On Windows (with MinGW): Use the following command:

sh Copy code gcc -o hello.exe hello.c 4. Run the Program On Linux/macOS: Execute the program with:

sh Copy code ./hello On Windows: Run the executable:

sh Copy code hello.exe 5. Create a Makefile (Optional) If you want to automate the build process, you can create a Makefile. Here’s a simple example:

makefile Copy code all: hello

hello: hello.c gcc -o hello hello.c

clean: rm -f hello all is the default target. It depends on the hello target. hello is built from hello.c using gcc. clean is a target to remove the generated files. Run make to build the program and make clean to clean up m64plus fz pro apk última versión.
