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。いくつかのメモリリークを伴うGTKのGUI
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：
