我正在使用此https://github.com/nodejs/node-addon-api/blob/master/master/doc/bigint.md文档作为参考,以从C ,但我会收到以下错误:
error: ‘BigInt’ in namespace ‘Napi’ does not name a type
Napi::BigInt HelloWrapped(const Napi::CallbackInfo& info);
这是我的源代码:
#include <napi.h>
#include "bigintexample.h"
std::int64_t bigintexample::hello() {
return 1234;
}
Napi::BigInt bigintexample::HelloWrapped(const Napi::CallbackInfo& info) {
Napi::Env env = info.Env();
Napi::BigInt returnValue = Napi::BigInt::New(env, bigintexample::hello());
return returnValue;
}
Napi::Object InitAll(Napi::Env env, Napi::Object exports) {
exports.Set("hello", Napi::Function::New(env, bigintexample::HelloWrapped));
return exports;
}
NODE_API_MODULE(NODE_GYP_MODULE_NAME, InitAll)
在napi.h中,只有在napi_version定义大于2147483646的情况下,bigint功能才能使用。
/home/user/bigint-napi/node_modules/node-addon-api/napi-inl.h:573:24: error: ‘napi_create_bigint_int64’ was not declared in this scope
napi_status status = napi_create_bigint_int64(env, val, &value);
通过添加一个定义解决了:
