Right way to include files from an external project?

Josz

Hello everybody,

I would like to include a C++ project into my Qt project; I created a subdirectory for content all data with a .pri inside.

here is the tree from my project:

        drawRange+
		 +drawRange.pro
		 +main.cpp
		 +---->drawRangeGUI    (here ist my Qt MainWindow)
		 +
		 +---->hmisg+
			    +hmisg.pri       (the pri for my subproject)
			    +hmisg.cpp
			    +---->erpc-1.7.1+
				            +---->erpc_c+
							+---->config                    <---	In each subdirectory here
							+---->infra			<---	are many files 
							+---->port			<---    that I want 
							+---->setup			<---    for my 
							+---->transports	        <---    project

I created the .pri, first manually, after from Qt Creator with "(right mouse button in the project)-->Add Existing Files"

Here is my drawRange.pro

QT       += core gui charts

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = drawRange
TEMPLATE = app
include(drawRangeGUI/drawRangeGUI.pri)
include(hmisg/hmisg.pri)

    drawRangeGUI/drawrange.pri

and my hmisg.pri.pri

But after compile, I obtained 86 errors of a project that did work in Visual Studio. it seems to have to do with the inclusion of <Windows.h>, <winsock2.h>, <ws2tcpip.h> and others among the files, because when I comment in a File <winsock2.h> and <ws2tcpip.h>, the number of errors falls to 24, but I get fails like

D:\@Qt_Projects\drawRange\hmisg\erpc-1.7.1\erpc_c\transports\erpc_tcp_transport_win.cpp:159: error: C2079: 'hints' uses undefined struct 'erpc::TCPTransport::connectClient::addrinfo'

for the next line:

struct addrinfo hints = { 0 };

with a little patience, I discovered that the structure is defined in <ws2def.h> like

typedef struct addrinfo
{
    int                 ai_flags;       // AI_PASSIVE, AI_CANONNAME, AI_NUMERICHOST
    int                 ai_family;      // PF_xxx
    int                 ai_socktype;    // SOCK_xxx
    int                 ai_protocol;    // 0 or IPPROTO_xxx for IPv4 and IPv6
    size_t              ai_addrlen;     // Length of ai_addr
    char *              ai_canonname;   // Canonical name for nodename
    _Field_size_bytes_(ai_addrlen) struct sockaddr *   ai_addr;        // Binary address
    struct addrinfo *   ai_next;        // Next structure in linked list
}
ADDRINFOA, *PADDRINFOA;

Is my way the right to include the files? Why I get this issues in a project that compile in other tool?

please, any help will be welcomed.
Thanks in advance

I found a solution

using:

#define _WINSOCKAPI_            // stops windows.h including winsock.h

before

#include <winsock2.h>
#include <ws2tcpip.h>
