njsgcs2025-06-07 22:09

复制代码

find /usr -name Emscripten.cmake

复制代码

/usr/share/emscripten/cmake/Modules/Platform/Emscripten.cmake

复制代码

find /usr -wholename "*/emscripten/bind.h"

复制代码

/usr/share/emscripten/system/include/emscripten/bind.h
/usr/share/emscripten/cache/sysroot/include/emscripten/bind.h

上面那个文件夹缺version.h

include_directories(/usr/share/emscripten/cache/sysroot/include/)

apt的不行

复制代码

git clone https://github.com/emscripten-core/emscripten.git

/home/chen/代码/chili3d/cpp/build/emscripten/system/include

复制代码

export PATH="/home/chen/软件/emsdk:$PATH"
export EMSDK="/home/chen/软件/emsdk"
export EM_CONFIG="$EMSDK/.emscripten"
export EMSCRIPTEN="$EMSDK/upstream/emscripten"

总结，加环境变量，bootstrap一下就好了

The "workspaces" field in package.json is not supported by pnpm. Create a "pnpm-workspace.yaml" file instead.

用pnpm i 会这样

复制代码

npm install -g cnpm --registry=https://registry.npmmirror.com

cpp 复制代码

#include "shared.hpp"  
#include <emscripten/bind.h>  
#include <iostream>  
#include <string>  
  
using namespace emscripten;  
  
class HelloWorld {  
public:  
    static std::string sayHello() {  
        return "Hello, World from C++!";  
    }  
      
    static std::string greet(const std::string& name) {  
        return "Hello, " + name + " from C++!";  
    }  
};  
  
EMSCRIPTEN_BINDINGS(HelloWorld) {  
    class_<HelloWorld>("HelloWorld")  
        .class_function("sayHello", &HelloWorld::sayHello)  
        .class_function("greet", &HelloWorld::greet);  
}
