我正在尝试交叉编译我使用MinGW-w64交叉编译器和CMake在Arch for Linux上编写的c ++程序。该程序使用g ++ for linux进行编译。使用MinGW-w64（x86_64-w64-mingw32）我收到很多编译错误。
问题在于包含sqlext.h或sql.h头文件。这是device.h头文件，其中包含ODBC头：

#if defined(_WIN32)
#include <windows.h>

和arbin.cpp实现：
#include "main.h"
#include "device.h"
#include "math.h"
#include <iostream>
#include <algorithm>
using namespace std;
// error handler for odbc sql queries
void Device::showError(SQLSMALLINT handleType, const SQLHANDLE& handle)

if (SQL_SUCCEEDED(retCode)) {

}
} while (retCode == SQL_SUCCESS);
}

以下是编译错误：

我不明白错误＆＃34;在'{'令牌＆＃34;之前预期的类名。 c ++继承似乎没什么问题，因为代码用g ++编译得很好。无法找到＆＃34; SQLRETURN类型的定义＆＃34;，这似乎没有正确包含sql头。我尝试了sql.h，sqlext.h和sqltypes.h的变种，但没有成功。
有什么想法吗？
