C++ & ta_lib - 无法弄清楚如何使用TA_MACD函数
C++ & ta_lib - cannot work out how to use TA_MACD function
这是我的第一个c++程序，我对c也不是很熟悉，所以请对我温柔!
我试图从ta_lib库调用TA_MACD函数，但没有成功。有人能帮我一下吗?
我的代码是:
#include <iostream>
#include "ta_libc.h"
using namespace std;
void go(const TA_Real *array[], TA_Integer fastPeriod, TA_Integer slowPeriod, TA_Integer signalPeriod);
struct Struct_Macd
{
double Macd;
double Signal;
double Histogram;
} MacdResult;
int main(int argc, char**argv)
{

当我使用MinGW编译时，我得到以下错误:

我会第一个承认我不知道我在做什么，所以任何帮助都会很感激。
另外，当我不知道TA_MACD函数返回多少时，我如何设置输出变量的大小?
提前感谢。
使用c++ 11 Std修改后，我现在在这里，仍然有问题。

@truf发现了一个愚蠢的错误，即e c指针引用不指向单个数组。
这是我最后的代码(太长了，所以这里是一个片段!)帮助那些也有问题的人:
MacdResult.Macd = outMacd.at(lastElement);
MacdResult.Signal = outSignal.at(lastElement);
MacdResult.Histogram = outHistogram.at(lastElement);
有几个问题(至少三个):
- io.cpp:51: error: cannot convert
TA_Real*' toconst TA_Real**'…- 使用简单的'const TA_Real *array'代替'const TA_Real *array[]'
- 不要使用'sizeof(array)/sizeof(*array)'来确定数组长度(它在函数内部不起作用)，只需将此长度传递给附加参数:void go(const TA_Real *array[]， TA_Integer array_size，…)并调用它:go(close_data, sizeof(close_data)/sizeof(*close_data)， 12,26,9);
- io.cpp:57:错误:' outMacd'的存储大小不知道
- 将大小放在括号中，例如:'TA_Real outMacd[array_size]'代替'TA_Real outMacd[]'
- io.cpp:61: error: cannot convert
const TA_Real**' toconst double*'…- 我希望这将自行解决:)
编辑:相应的TA_MACD源(http://sourceforge.net/p/ta-lib/code/HEAD/tree/trunk/ta-lib/c/src/ta_func/ta_MACD.c)，我们的变量的大小是(endIdx-startIdx+1)。
EDIT2:嗯，c++ 11让事情变得更糟:)TA_Lib使用的是普通的C接口，所以你需要准确地转换c++对象和C类型。
我建议这样做:
-
使用vector代替array (c++ 11兼容编译器)
#include <array> vector<TA_Real> close_data { 31.09999000,1.09995000,1.09996000, ... } -
所以你不需要在调用
时传递数组长度go(close_data,12,26,9); -
编辑函数(vector::data()也需要c++ 11兼容编译器)
void go(const vector<TA_Real> &close, TA_Integer fastPeriod, TA_Integer slowPeriod, TA_Integer signalPeriod) { TA_Integer outBegin = 0, outElements = 0; vector<TA_Real> outMacd(array_size, 0.0); vector<TA_Real> outSignal(array_size, 0.0); vector<TA_Real> outHistogram(array_size, 0.0); TA_RetCode retCode = TA_MACD( array_size-1-slowPeriod, array_size-1, close.data(), fastPeriod, slowPeriod, signalPeriod, outBegin, outElements, outMacd.data(), outSignal.data(), outHistogram.data() ); if(retCode == TA_SUCCESS) { int lastElement = outElements-1; MacdResult.Macd = outMacd[lastElement]; MacdResult.Signal = outSignal[lastElement]; MacdResult.Histogram = outHistogram[lastElement]; cout << "Macd = " << MacdResult.Macd << " Signal = " << MacdResult.Signal << " Histograme = " << MacdResult.Histogram << endl; } }
不幸的是，我无法用编译器重新检查这段代码，所以使用它作为模板，并在出现错误时进行更改。
EDIT3:
到底是什么函数"Z2goRSt6vectorIdSaIdEEiii"????
是的，c++喜欢这样的名字!它是编码的，编译器内部名称的go()函数。你可以看到名称- 'go'，参数类型- 'vector'， i (integer)等等。
C:/Users/ypx7647/Documents/c++/Test/main.cpp:30:对' TA_MACD'的未定义引用
看起来TA_lib需要在链接器命令行中构建和指定外部库文件。您可以查看ta-lib/README.TXT文件获取说明。
- 。进入:ta-lib/c/make/csr/linux/g++/并在那里运行'make'
- 在编译器命令行中添加lib文件和lib文件的路径:
mingw32-g + + . exe[…-lta_libc_csr.a
另外，我不能检查这个，所以在错误的情况下要有创造性，祝你好运!
