brew install llvm@18 pkg-config bdw-gc openssl python@3.12
git clone https://github.com/goplus/llgo && cd llgo
make
# 运行
./llgo run main.go

<h2 class="llgo-summary-title">总结</h2>
<p class="llgo-text">
LLGo 不是官方编译器的替代品，而是"Go + C + Python"三栖场景的加速器。如果你需要：
</p>
<ul class="llgo-summary-list">
<li>在 Go 里直接调用现成 C 库/Python 模型</li>
<li>把 Go 跑在 WebAssembly、嵌入式或高性能计算环境</li>
<li>体验 LLVM 带来的优化潜力</li>
</ul>
<p class="llgo-text" style="margin-top: 16px;">
那么 LLGo 值得拉下来试跑一波。
