Qmake and prl files

gserm

I am trying to get my head around how prl files work. Working on a Windows machine, I have created two static libraries, lib1.lib (exporting void my_lib1_func()) and lib2.lib (exporting void my_lib2_func() which uses my_lib1_func). I then create a console app which I link statistically against lib2.lib. Unfortunately, when trying to compile it the compiler complains that it can't find my_lib1_func.

I was under the impression that qmake's prl files would tackle this issue as explained here, but unfortunately I haven't been successful using it. Below is the source code, there are a few files but they are trivial. The directory structure structure is as follows:

    root
	|---my_lib1
		|---my_lib1.pro
		|---my_lib1.cpp
		|---my_lib1_header.h
	|---my_lib2
		|---my_lib2.pro
		|---my_lib2.cpp
		|---my_lib2_header.h
	|---main
		|---main.pro
		|---main.cpp


//my_lib1_header.h
#pragma once
void my_lib1_func();



// my_lib1.cpp
#include <iostream>
#include "my_lib1_header.h"

void my_lib1_func() {
	std::cout << "Hello" << std::endl;
}



#my_lib1.pro

TEMPLATE = lib

HEADERS += my_lib1_header.h
SOURCES += my_lib1.cpp

TARGET = my_lib1
CONFIG += static create_prl
CONFIG -= qt



//my_lib2_header.h
#pragma once

void my_lib2_func();




//my_lib2.cpp
#include "../my_lib1/my_lib1_header.h"
#include "my_lib2_header.h"
#include <iostream>

void my_lib2_func() {
	my_lib1_func();
	std::cout << "World" << std::endl;
}




#my_lib2.pro

TEMPLATE = lib

SOURCES += my_lib2.cpp

CONFIG += static link_prl create_prl
CONFIG -= qt

CONFIG(debug, debug|release) {
	LIBS += ../my_lib1/debug/my_lib1.lib
}

CONFIG(release, debug|release) {
	LIBS += ../my_lib1/release/my_lib1.lib
}



// main.cpp
#include "../my_lib2/my_lib2_header.h"

int main() {
	my_lib2_func();
}




#main.pro
TEMPLATE = app
CONFIG -= qt
CONFIG += console link_prl

CONFIG(debug, debug|release) {
	LIBS += ../my_lib2/debug/my_lib2.lib
}

CONFIG(release, debug|release) {
	LIBS += ../my_lib2/release/my_lib2.lib
}

SOURCES += main.cpp

The resulting Makefile for main.cpp links against the my_lib2.lib but not against my_lib1.lib, despite the prl file being generated. Any help would be appreciated!

I'd be interested to know if you came up with a solution for this, as I've also run up against the same problem. In our project, we've ended up having every of the dependent libs specified in the pro files which is not ideal.
