swig && c++ 安装

swig 版本必须 >= 3.0以上,最新的4.1;

yum install gcc-c++ 安装C++;

Go 低版本的 比如: 1.8.7 编译时报错 -std 的问题; 升级 Go版本, 1.10以上未出现问题,1.9不清楚;

goctp/goctp.swigcxx 修改

# 注释掉如下代码 => 在 example/goctp_md_example.go 中,修改如下:

func (p *GoCThostFtdcMdSpi) SubscribeMarketData(symbols []string) {

    args := make([]*C.char, 0)
    for _, v := range symbols {
        symbol := C.CString(v)
        defer C.free(unsafe.Pointer(symbol))
        args = append(args, symbol)
    }

    iResult := p.Client.MdApi.SubscribeMarketData((*string)(unsafe.Pointer(&args[0])), len(symbols))

    if iResult != 0 {
        log.Println("发送行情订阅请求: 失败.")
    } else {
        log.Println("发送行情订阅请求: 成功.")
    }
}

func (p *GoCThostFtdcMdSpi) SubscribeForQuoteRsp(symbols []string) {

    args := make([]*C.char, 0)
    for _, v := range symbols {
        symbol := C.CString(v)
        defer C.free(unsafe.Pointer(symbol))
        args = append(args, symbol)
    }

    iResult := p.Client.MdApi.SubscribeForQuoteRsp((*string)(unsafe.Pointer(&args[0])), len(symbols))

    if iResult != 0 {
        log.Println("发送询价订阅请求: 失败.")
    } else {
        log.Println("发送询价订阅请求: 成功.")
    }
}

//%typemap(gotype) (char **ppInstrumentID, int nCount) "[]string"
//
//%typemap(in) (char *ppInstrumentID, int nCount)
//%{
//  {
//    int i;
//    _gostring_* a;

//%}

ThostFtdcUserApiDataType.h 问题

# v6.3.15_20190220_api_tradeapi_se_linux64 版本的该头文件 将字符串以 ''括起来,导致 SWIG翻译时报错;

将类似 '102001' 的都转为 ""; 否则编译成.go之后 出现
  const THOST_FTDC_VTC_BankBankToFuture byte '102001' 编译器退出报错; 
  实际上应该是:
  const THOST_FTDC_VTC_BankBankToFuture string "102001"

#define THOST_FTDC_VTC_BankBankToFuture "102001"
#define THOST_FTDC_VTC_BankFutureToBank "102002"
#define THOST_FTDC_VTC_FutureBankToFuture "202001"
#define THOST_FTDC_VTC_FutureFutureToBank "202002"
 
#define THOST_FTDC_FTC_BankLaunchBankToBroker "102001"
#define THOST_FTDC_FTC_BrokerLaunchBankToBroker "202001"
#define THOST_FTDC_FTC_BankLaunchBrokerToBank "102002"
#define THOST_FTDC_FTC_BrokerLaunchBrokerToBank "202002"

编译后 libthostmduserapi.so => not found 的问题

# 默认的动态加载库在 /usr/lib 目录下,而非 /usr/local/lib (建立软连接即可)

sudo ln -s /usr/local/lib/libthostmduserapi.so /usr/lib/libthostmduserapi.so
sudo ln -s /usr/local/lib/libthosttraderapi.so /usr/lib/libthosttraderapi.so

最后执行例子

./goctp_md_example

CTP: 2019/07/10 13:49:33.854960 usage: ./goctp_md_example -BrokerID 9999 -InvestorID 000000 -Password 000000 -MarketFront tcp://180.168.146.187:10010 -TradeFront tcp://180.168.146.187:10000
