いくつかのメモリリークを伴うGTKのGUI

Question

短時間の間、私はGTK-3.0を学び始めました。私が働くプログラムのGUIを作成し始めました。

プログラムは警告なしでコンパイルされますが、valgrindで実行すると、メモリリークが多く発生し、私が何をやっているのか分かりません。

私は自分のプログラムを最小限のコードに減らしました。問題を簡単に説明できるようにしました。以下のコードに

は細かいが、メモリリークの多くでコンパイル：

#include <gtk/gtk.h> 

int main(int argc, char *argv[]){ 
    gtk_init(&argc, &argv); 
    GtkWidget *window; 
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 

    g_signal_connect(window, "delete-event", G_CALLBACK(gtk_main_quit), NULL); 
    gtk_widget_show(window); 
    gtk_main(); 
} 

私はそれをコンパイル：

gcc -Wpedantic -std=c11 -Wall -Wextra -Werror -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wconversion -Wshadow -Winit-self -Wfloat-equal -Wwrite-strings -O0 -g main.c -o app `pkg-config --cflags gtk+-3.0 ` `pkg-config --libs gtk+-3.0 ` 

と、私は次のコマンドでvalgrindを実行した後：

valgrind --leak-check=full --track-origins=yes --leak-check=full ./app 

私は以下の出力を得ます：

私が本を読んだ後、GTK3 Manualに続いて、どこに漏れがあるのか​​分かります。

私はここでGUIを間違って始めましたか？マニュアルから、私はそれが正しい方法でコード化されていると確信しています。

valgrind出力では、callocとreallocがコールされたことがわかります。これは、free()コールが必要であることを意味します。 GTK +でメモリを解放するにはどうしたらいいですか？

Answer 1

これは何度もここで回答されています。これは私が私が適度に使用フォーラムでこれを尋ねた他の誰かへの答えとして与えたものである：それはアプリケーションの人生の時間のために必要な内部バッファを割り当て、割り当て解除に来るとき

GTK +はかなり怠惰です。例えば、アプリケーションの寿命のために必要とされる、初期化中にルックアップテーブルのためのメモリ領域を割り当てることができる。 GTK +はこれを決して割り当て解除しません。 Valgrindの場合、これはメモリリークのように見えますが（技術的にはそうですが）、最適化としてGTK +はアプリケーションの終了時に割り当てが解除されるため、エラーではなく、割り当てを解除しません。 Valgrindがこれらを無視できるように抑制ファイルが必要なのはこのためです。問題は、ほとんどのGTK +バージョンの変更でこれらを変更する必要があることです。

あなたが見ているのは誤認です。 valgrindがこれらを無視できるように、抑制ファイルを使用することができます。自分で作成したり、すでに完了しているものを検索することができます。
