How to Fix the "Source File Not Compiled" Error in Dev C++

✨ Introduction

While experimenting with C programming using Dev C++, I ran into an error that stumped me for hours:
“Source file not compiled”

At first, I thought it was just a syntax issue or something I’d overlooked. But after multiple failed attempts, I realized the issue was deeper, and I’m not the only one who’s faced it.

In this blog, I’ll share:

• What causes this issue

• What didn’t work

• What worked perfectly

• A step-by-step guide to setting up the right version of Dev C++ for Windows 10/11

• Plus, resources and alternative tools you can explore

😵‍💫 The Issue

After researching, I discovered that the original Bloodshed Dev C++ is not compatible with Windows 10. Worse still, it didn’t even detect intentional syntax errors during compilation, making debugging even more confusing.

🧪 Troubleshooting: What I Tried

When searching online, I came across many suggestions, including:

• Renaming or deleting collect2.exe — can break your compiler

• Manual compiling via command line — too advanced for beginners

• Changing compiler settings — hit or miss

• Deleting the .exe file manually — temporary fix

• Updating PATH environment variables — not always the issue

• Creating new projects instead of opening .c files directly — occasionally helpful

These were all “maybe” solutions that didn’t consistently work for me.

✅ What Actually Worked

After trying multiple fixes, the most reliable solution was:
🛠️ Installing the latest version of Dev C++ from Embarcadero.

The classic Bloodshed version is outdated and no longer maintained, leading to compatibility issues. The Embarcadero version, on the other hand, is actively maintained and includes an updated GCC compiler, making it much more stable on modern systems.

Where to Download:

• 🔗 Dev C++ on SourceForge

• 🔗 GitHub repositories (search “Embarcadero Dev C++”)

• 🔗 Official Embarcadero Dev-C++ page

🧭 How to Download & Install Dev C++ (Step-by-Step)

1. Visit the official download page

2. Click the green “Download” button (or wait for it to start automatically)

3. Open the installer once downloaded

   • If prompted by Windows, click “Run anyway”

4. Follow the installation wizard:

   • Choose your language

   • Accept the license agreement

   • Select installation location (default is fine)

5. Launch Dev C++

To Test:

1. Create a new C project:
   File > New > Project > Console Application > C

2. Add your .c file and write a simple program like:

#include <stdio.h>

int main() {
    printf("Hello, world!\n");
    return 0;
}

3. Click Execute > Compile and Run
   If everything’s working, “Hello, world!” will appear in a console window — success!

🧱 Bonus Tip: Consider Better Tools

While Embarcadero Dev C++ is a much-improved version, you might also want to try more modern IDEs:

• Code::Blocks – Great for both C and C++

• Visual Studio Code + MinGW – Clean, customizable, and modern

• Orwell Dev-C++ – Another actively maintained fork

But if you’re just starting out, Embarcadero Dev C++ is a solid starting point.

---

TL;DR

• That error happens because old Dev C++ is outdated and incompatible

• Don’t waste time trying to fix it. Install the Embarcadero version instead

• Follow the step-by-step guide above to get started easily

• Consider switching to modern IDEs later

Conclusion

If you’re new to C and encounter the “source file not compiled” error, don’t panic. It’s not your fault. It’s usually the tool.

Just install the updated version of Dev C++ from Embarcadero. Once I made the switch, everything worked smoothly. No strange fixes, no terminal commands.

Getting stuck on basic things can be frustrating, especially when you're just starting to learn a new language like C. But that’s normal — and totally fixable.
