[Solved] Building a simple example using MinGW from command line

I have MinGW on Windows. I downloaded Urho3D-1.7.1-MinGW-STATIC and I placed the “include” and “lib” folders here:

• E:\Libs\Urho3D-1.7.1-MinGW-STATIC\include
• E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D

The “lib\Urho3D” folder contains the “libUrho3D.a” file.

I wrote a very simple example with minimal code to show that it compiles and works:

#include <iostream>
#include <Urho3D/Engine/Application.h>

class MyApp : public Urho3D::Application
{
public:
    MyApp(Urho3D::Context * context) : Urho3D::Application(context)
    {
    }

    virtual void Setup()
    {
        std::cout << "Setup" << std::endl;
    }
};

URHO3D_DEFINE_APPLICATION_MAIN(MyApp)

I try to compile it using this command:

g++ main.cpp -I"E:\Libs\Urho3D-1.7.1-MinGW-STATIC\include" -L"E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D" -lUrho3D -o app.exe

I see a lot of errors like:

E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D/libUrho3D.a(SDL_winmm.c.obj):SDL_winmm.c:(.text+0x942): undefined reference to `_imp__waveOutGetNumDevs@0’

E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D/libUrho3D.a(SDL_winmm.c.obj):SDL_winmm.c:(.text+0x97b): undefined reference to `_imp__waveOutGetDevCapsW@12’

E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D/libUrho3D.a(SDL_winmm.c.obj):SDL_winmm.c:(.text+0xa32): undefined reference to `_imp__waveInAddBuffer@12’

I added this key -lwinmm and I do not see the error message related to SDL_winmm.c above.

What key do I need to solve this error:

E:\Libs\Urho3D-1.7.1-MinGW-STATIC\lib\Urho3D/libUrho3D.a(SDL_windowsframebuffer.c.obj):SDL_windowsframebuffer.c:(.text+0x38a): undefined reference to `_imp__DeleteObject@4’

I would strongly suggest using CMake to get all the build flags correct. If you wish to switch over to just the command line after that you can just run make with VERBOSE=1 and see what the actual commands to compile the project were.

Also, welcome to the community!

Welcome to the community!

I can offer some minor notes…
Building from the master branch on github is frequently recommended as it maintains good stability, and there have been a number of fixes since last release.

Possibly helpful to MingW users,

#pragma once
// Somewhat limit windows header namespace pollution.

#ifdef _WIN32
#define WIN32_LEAN_AND_MEAN
#define NOSERVICE
#define NOMCX
#define NOIME
#define NONLS
#include <windows.h>
#undef CreateDirectory
#undef GetClassName
#undef GetProp
#undef RemoveProp
#undef SetProp
#endif

S.L.C offers a more sophisticated method:

Thank you, guys!

My steps:

1. I downloaded a source from the master branch.
2. I run CMake GUI.
3. I selected “MinGW Makefiles” and “Use default native compilers”
4. I choose the “source” and “dist” folders.
5. I pressed the “Configure” button. There are some warnings at the beginning that I do not understand:

6. I just unchecked some Assimp Importers. I pressed the “Configure” button again.
7. I pressed the “Generate” button.
8. I went to the “dist” folder and I run the “mingw32-make” command.
9. Even EXE’s for examples was created successfully.
10. I have the “include” folder and the “libUrho3d.a” library. I think it must be enough to build a simple program:

#include <iostream>
#include <Urho3D/Engine/Application.h>

class MyApp : public Urho3D::Application
{
public:
    MyApp(Urho3D::Context * context) : Urho3D::Application(context)
    {
    }

    virtual void Setup()
    {
        std::cout << "Setup" << std::endl;
    }
};

URHO3D_DEFINE_APPLICATION_MAIN(MyApp)

11. I run the command:

g++ -Wall -g -std=c++11 main.cpp -I"C:\Users\8Observer8\Downloads\Urho3D-master\dist\include" -L"C:\Users\8Observer8\Downloads\Urho3D-master\dist\lib" -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -lwinmm -limm32 -lversion -lws2_32 -ldbghelp -ld3dcompiler -ld3d11 -ldxgi -ldxguid -o app.exe

12. This is the whole output:

For example, I use a similar command for building apps with the SFML library. This command works correctly:

g++ main.cpp -I"E:\Libs\SFML\SFML-2.5.1-windows-gcc-7.3.0-mingw-32-bit\SFML-2.5.1\include" -L"E:\Libs\SFML\SFML-2.5.1-windows-gcc-7.3.0-mingw-32-bit\SFML-2.5.1\lib" -lsfml-graphics -lsfml-window -lsfml-system -o hero.exe

Maybe do I use incorrect keys? Where can I find correct keys?

This problem was solved using this key: -lSetupapi

But what key will solve this problem:

C:/Users/8Observer8/Downloads/Urho3D-master/dist/include/Urho3D/Engine/Application.h:37: undefined reference to `_imp___ZN6Urho3D8TypeInfoD1Ev’

This command:

g++ -Wall -g -std=c++11 main.cpp -I"C:\Users\8Observer8\Downloads\Urho3D-master\dist\include" -L"C:\Users\8Observer8\Downloads\Urho3D-master\dist\lib" -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -lwinmm -limm32 -lversion -lws2_32 -ldbghelp -ld3dcompiler -ld3d11 -ldxgi -ldxguid -lSetupapi -o app.exe

gives me these errors:

Looks like it can’t find the libUrho3D.a, are you sure you’re linking to the correct folder?

When I break the path:

g++ -Wall -g -std=c++11 main.cpp -I"C:\Users\8Observer8\Downloads\Urho3D-master\dist\include" -L"C:\Users\8Observer8\Downloads\Urho3D-master\dist" -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32

I get this:

C:/Program Files (x86)/mingw-w64/i686-8.1.0-win32-dwarf-rt_v6-rev0/mingw32/bin/../lib/gcc/i686-w64-mingw32/8.1.0/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lUrho3D collect2.exe: error: ld returned 1 exit status

As I suggested before, run the make command verbosely and see the actual commands used to compile something, let’s say one of the samples. I think you’re missing some of the flags, but I can’t tell you just from looking at then which will be needed.

From your CMake output:

CFLAGS: -mtune=generic -march=native -msse3 -static -static-libgcc -fno-keep-inline-dllexport -mstackrealign -fdiagnostics-color=auto -IC:/Users/8Observer8/Downloads/Urho3D-master/Source/ThirdParty/SDL/src/hidapi/hidapi
EXTRA_CFLAGS: -Wshadow -Wdeclaration-after-statement -Werror=declaration-after-statement -fno-strict-aliasing -Wall

EXTRA_LIBS: m;user32;gdi32;winmm;imm32;ole32;oleaut32;version;uuid;advapi32;setupapi;shell32;dinput8;dxerr8

I did not understand you before. Now I understand that I need to run the next command and I will try it later:

mingw32-make VERBOSE=1

The build command above works with “shared” version of Urho. I downloaded Urho3D-1.7.1-MinGW-SHARED. When I run the command:

g++ -Wall -g -std=c++11 main.cpp -I"C:\Users\8Observer8\Downloads\Urho3D-1.7.1-MinGW-SHARED\include" -L"C:\Users\8Observer8\Downloads\Urho3D-1.7.1-MinGW-SHARED\lib\Urho3D" -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -lSetupapi -ladvapi32 -lwinmm -limm32 -lversion -lws2_32 -ldbghelp -lopengl32 -o app.exe

I get “app.exe”. But I get this warning after compilation:

I copied the “Urho3D.dll” from the folder:

• C:\Users\8Observer8\Downloads\Urho3D-1.7.1-MinGW-SHARED\bin

to

• C:\Windows\SysWOW64

I run “app.exe” and It works! I read here that I need to add “Data” and “CoreDate”.

// #include <Urho3D/Urho3D.h>
#include <Urho3D/Engine/Application.h>
#include <iostream>

class MyApp : public Urho3D::Application
{
public:
    MyApp(Urho3D::Context * context) : Urho3D::Application(context)
    {
    }

    virtual void Setup()
    {
        std::cout << "Setup" << std::endl;
    }
};

URHO3D_DEFINE_APPLICATION_MAIN(MyApp)

It is time to study and practice with Urho. I will try to compile statically an example later. Thank you, guys!

Glad you got it working! To fix those errors make sure you have the necessary files in either Data or CoreData (they should be in bin/*Data/

Other than that, the only thing I would recommend is that you use Urho’s log macros (in IO/Log.h) rather than std::cout in general so that the redirection to a file and such will all be handled uniformly.

I will save my Makefile for the future. Maybe it will useful for beginners. If you want to use VSCode install the C/C++ for Visual Studio Code plugin. Press Ctrl+Shift+P and select C/C++: Edit Configurations (UI). Open the .vscode/c_cpp_properties.json file and include path to the Urho3D include folder:

            "includePath": [
                "${workspaceFolder}/**",
                "E:/Libs/Urho3D-1.7.1-MinGW-SHARED/include"
            ],

Makefile

CC = g++

INC = -I"E:\Libs\Urho3D-1.7.1-MinGW-SHARED\include"

LIB = -L"E:\Libs\Urho3D-1.7.1-MinGW-SHARED\lib\Urho3D"

FLAGS = -c

	$(CC) main.o -Wall -g -std=c++11 $(LIB) -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -lSetupapi -ladvapi32 -lwinmm -limm32 -lversion -lws2_32 -ldbghelp -lopengl32 -o app

URHO3D_DEFINE_APPLICATION_MAIN(MyApp)

Build the project: mingw32-make

My step-by-step tutorial for beginners: [Tutorial] How to set up Urho3D (Shared, MinGW) in Qt Creator IDE

I tried to build Urho3D statically from source using CMake and MinGW32 but it is really looks like it cannot find the libUrho3D.a. Because I tried to delete “-lUrho3D” from settings and I get 21 errors like:

My settings:

CONFIG += c++11

INCLUDEPATH += "C:\Users\8Observer8\Downloads\Urho3D-1.7.1\dist\include"

LIBS += -L"C:\Users\8Observer8\Downloads\Urho3D-1.7.1\dist\lib"

LIBS += -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32

LIBS += -ldbghelp -limm32 -lversion -lwinmm -lws2_32

SOURCES += \
    main.cpp

I want to mention that if I delete -lUrho3D I get 21 errors and if I do not delete -lUrho3D from settings above I get the same 21 errors in any case. This path is correct: C:\Users\8Observer8\Downloads\Urho3D-1.7.1\dist\lib:

Since MinGW is just GCC you could #pragma push those macros in case you need them later. You probably don’t but a mere suggestion.

#if defined (__MINGW32__) || defined (__MINGW64__)
#pragma push_macro("CreateDirectory")
#endif
#undef CreateDirectory
//...

And later if you need one:

#pragma pop_macro("CreateDirectory")

Although this probably complicates things more than it should
Reason I included this suggestion is in case you do it in a global header.

By Building from source do you mean using the supplied urho3d build setup?

I downloaded the Urho3D-1.7.1 archive here: https://github.com/urho3d/Urho3D/releases I used CMake-GUI to configure and generate a project. And I use the mingw32-make command to make libUrho3D.a.

These are my settings. I just deleted some importers:

image553×720 29.7 KB

image553×720 30.3 KB

image553×720 28.6 KB

image553×720 25.5 KB

image553×720 26.8 KB

image553×720 27.1 KB

image553×720 26.6 KB

Ok. I assume from this stage you go ahead to click the “Generate” button.

After it is done generating your build files, you navigate to your build directory and through CMD run

mingw32-make -f makefile install

Was that your procedure?

Yes, I clicked the Generate button. I opened the “dist” folder and opened CMD in the “dist” folder. I wrote the “mingw32-make” command. After 10 minutes of successful building I got libUrho3D.a in the folder: C:\Users\8Observer8\Downloads\Urho3D-1.7.1\dist\lib

I will try this command.

To use the command

mingw32-make -f makefile install

ensure that your properly set the value for CMAKE_INSTALL_PREFIX, it should be the directory you want Urho3D to be installed in

I think I must to run CMD as Admin:

It does not work again:

But a few days ago I made the same steps (CMake and so on) with Allegro5 and it works:

        {

            al_flip_display();
            redraw = false;
        }

        al_wait_for_event(queue, &event);

        switch (event.type)
        {
            case ALLEGRO_EVENT_KEY_DOWN:
                if (event.keyboard.keycode == ALLEGRO_KEY_ESCAPE)

                break;
        }
    }

    return 0;
}

It very complicated for me. I am not an expert in .pro files but I will try later. Thank you! But it is very strange that Urho3D does not work in my settings because Allegro5 works fine with the same steps and settings.

Is it possible to post the content of your main.cpp and any companion header file of your urho3d setup.

Using a Urho3D-1.7.1 build I was able to successfully reproduce the error and seems to have identified what was actually causing it. Below is the modified .pro file of QT Creator that should work

CONFIG += c++11

INCLUDEPATH += "C:\Program Files (x86)\Urho3D\include"

LIBS += -L"C:\Program Files (x86)\Urho3D\lib"

DEFINES += URHO3D_STATIC_DEFINE

LIBS += -lUrho3D -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
LIBS += -ldbghelp -limm32 -lversion -lwinmm -lws2_32 -lopengl32

SOURCES += \
    main.cpp

The first of the additions to your previous setting is DEFINES += URHO3D_STATIC_DEFINE. Personally I usually include all the Urho Defines used in building the lib, however, URHO3D_STATIC_DEFINE seems to be the minimum needed for the code in your main.cpp to run.

The next addition is -lopengl32 added after the last LIBS +=

With these modification I was able to build and run the main.cpp you posted without any error.

21 errors again:

I even tried to build to Static Release:

But in this case I got 51 errors:

Might I ask where did you get the MinGW you’re using?

From Qt: C:\Qt5\Tools\mingw810_32\bin

@Bluemoon, what MinGW version did you use to build Urho3D? I think it is better to use the same MinGW that I use for my development environment. I use Qt Creator and Qt libraries.

My MinGW is v8.1.0

One more request.

navigate to the installation directory of your urho3d build. inside the /lib/pkgconfig folder look for a Urho3D.pc file. Post the content of this file let me take a look, you can also study the content yourself.

prefix=C:/Program Files (x86)/Urho3D
exec_prefix=${prefix}
libdir=${exec_prefix}/lib/.
includedir=${prefix}/include

# Additional Cflags for various build configurations, which can be accessed as normal pkg-config variable using '--variable' option
CFLAGS_DEBUG=-g -DDEBUG -D_DEBUG
CFLAGS_RELEASE=-O2 -DNDEBUG
CFLAGS_RELWITHDEBINFO=-O2 -g -DNDEBUG

Name: Urho3D
Description: Urho3D is a free lightweight, cross-platform 2D and 3D game engine implemented in C++ and released under the MIT license. Greatly inspired by OGRE (http://www.ogre3d.org) and Horde3D (http://www.horde3d.org).

So what I have below is QT Creator .pro file generated from the values in your Urho3D.pc . You can try using it

CONFIG += c++11

INCLUDEPATH += "C:\Program Files (x86)\Urho3D\include"

LIBS += -L"C:\Program Files (x86)\Urho3D\lib"

SOURCES += \
    main.cpp

As an addition, can you ensure that the compiler has access permission to C:\Program Files (x86)\Urho3D

Result:

Result for Qt Static:

I found the problem for Qt Debug! I made “Clean” here:

And now It works for Qt Debug:

But it does not work for Qt Static Release. What ideas?

I made “Clean” for Static Release and now I have another errors:
