Ich kann gtk GUI nicht mit cmake und MinGW gcc Compiler

Question

Ich benutze mit Windows 8.1 OS. Beide MinGW- und GTK-Pfade werden zu meiner Pfadumgebungsvariablen hinzugefügt. Ich habe Probleme, meinen Code mit den gtk-Bibliotheken zu verknüpfen.

hier ist die CMakeLists

# Set project 
cmake_minimum_required(VERSION 3.0) 
project(gtk-test C) 

# Configure project paths 
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/bin) 
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/lib) 
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/lib) 
set(CMAKE_SOURCE_DIR ${CMAKE_SOURCE_DIR}/src) 

# Find dependencies 
find_package(PkgConfig REQUIRED) 
pkg_check_modules(GTK3 REQUIRED gtk+-3.0) 
link_directories(${GTK3_LIBRARY_DIRS}) 
add_compile_options(${GTK3_CFLAGS_OTHER}) 
set(LIBRARIES ${LIBRARIES} ${GTK3_LIBRARIES}) 

set(FLAGS "-I${GTK3_INCLUDE_DIRS}") 
message(STATUS "Flags: ${FLAGS}") 
string(REPLACE ";" " -I" FLAGS "${FLAGS}") 
set(CMAKE_C_FLAGS ${CMAKE_C_FLAGS} ${GTK3_FLAGS} ${FLAGS}) 

# Compile 
add_executable(main ${PROJECT_SOURCE_DIR}/example.c) 
target_link_libraries(main ${LIBRARIES}) 

hier ist die Patch-Datei, die ich zu bauen verwenden.

@echo off 

set CMAKE_PATH=%~dp0..\Tools\CMake\bin 
set MAKE_PATH=%~dp0..\Tools\Make 
set PKG_CONFIG_PATH=C:\gtk3\lib\pkgconfig 
set PATH=C:\gtk3\bin;%PATH% 
set PATH=%PATH%;%CMAKE_PATH%;%MAKE_PATH% 
rd /s /q .\Builds 
mkdir Builds 
cd Builds 
cmake .. -G "MinGW Makefiles" 
cmake .. -G "MinGW Makefiles" 
call mingw32-make all -j4 

cd .. 

Hier ist der GUI-Code, den ich versuche zu bauen.

#include <gtk/gtk.h> 

int main(int argc, char *argv[]) 
{ 
GtkBuilder *gtkBuilder; 
    GtkWidget *window; 
    GError  *error = NULL; 
    gtk_init(&argc, &argv); 

    gtkBuilder = gtk_builder_new(); 
    if(!gtk_builder_add_from_file(gtkBuilder, "gui_config.glade", &error)) 
    { 
     g_warning("%s", error->message); 
     g_free(error); 
     return(1); 
    } 
    window = GTK_WIDGET(gtk_builder_get_object(gtkBuilder, "crc_main")); 

    /* Connect signals */ 
    gtk_builder_connect_signals(gtkBuilder, NULL); 

    /* Destroy builder, since we don't need it anymore */ 
    g_object_unref(G_OBJECT(gtkBuilder)); 

    gtk_widget_show(window); 
    gtk_main(); 

    return 0; 
} 

MinGW versagt GTK-Bibliotheken mit meinem GUI-Code zu verknüpfen, ist hier der Fehler erhalte ich:

Answer 1

Ihre CMakelists sieht komisch aus, als ob Sie alles von Hand machen wollen. Schauen Sie sich das alte CMakeLists.txt: https://stackoverflow.com/a/5105523/518853

Es ist für GTK 2 aber leicht angepasst, wenn Sie die 2 durch 3 ersetzen.

By the way, ist das GTK-Projekt von Autotool zum Meson Build-System langsam migrieren, so wan Sie vielleicht einen Blick auf, wie eine Meson-Build-Datei für eine GTK app aussieht geben:

project('tutorial', 'c') 
gtkdep = dependency('gtk+-3.0') 
executable('demo', 'main.c', dependencies : gtkdep)
