CJIT

CJIT started as a hobby project around Fabrice Bellard’s tinyCC and slowly grew into something much more practical. It is now a small portable C compiler and runner that works across Linux, macOS, and Windows, can self host, and is packaged as a single executable. What mattered most to me was keeping the barrier to entry low. You can take one small binary, drop it onto a system, and compile or run C code using the libraries already available there, without setting up a full toolchain or installing a large stack of dependencies. I find that useful for quick prototyping, testing, auditing,…

What it does

CJIT is a C interpreter that lets you run C code instantly, without needing to build it first. It is just one 2MB file and can do everything a C compiler does, including call functions from any installed library. It works on Linux, Windows, and MacOSX.

Run, compile, and link C programs instantly with CJIT.

A tiny, portable C runner and compiler powered by TinyCC. Write C, run it immediately, or produce objects and executables without setting up a full toolchain. Compile C in memory and execute it directly for fast experiments, scripts, and prototypes. Compile one source file to an object or link an executable without running the program. Load shared libraries and make their exported symbols available to your C program. CJIT bundles TinyCC, its headers, and runtime assets into a portable command-line executable. cjit hello.c Pass arguments to the compiled program after -- : cjit app.c -- --name cjit --verbose Or produce a file without executing it: Follow the tutorial for installation and…from dyne.org

  • I built a Cargo-like build tool for C/C++Apr 2026 · github.com · ▲177

    I love C and C++, but setting up projects can sometimes be a pain. Every time I wanted to start something new I'd spend the first hour writing CMakeLists.txt, figuring out find_package, copying boilerplate from my last project, and googling why my library isn't linking. By the time the project was actually set up I'd lost all momentum. So, I built Craft - a lightweight build and workflow tool for C and C++. Instead of writing CMake, your project configuration goes in a simple craft.toml: [project] name = "my_app" version = "0.1.0" language = "c" c_standard = 99 [build] type = "executable"…

  • Talanoa▲341

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Lovable▲1,477

    Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…
