我尝试在c 中使用IUP
我测试这个例子
#include <stdlib.h>
#include <iup/iup.h>
int main(int argc, char **argv)
{
Ihandle *dlg, *label;
IupOpen(argc, argv);
label = IupLabel("Hello world from IUP.");
dlg = IupDialog(IupVbox(label, NULL));
IupSetAttribute(dlg, "TITLE", "Hello World 2");
IupShowXY(dlg, IUP_CENTER, IUP_CENTER);
IupMainLoop();
IupClose();
return EXIT_SUCCESS;
}
我像这个一样编译它
gcc q.c -liup -o q
gcc给了我这个
q.c: In function â€کmain’:
q.c:6:3: warning: passing argument 1 of â€کIupOpen’ makes pointer from integer without a cast [enabled by default]
IupOpen(argc, argv);
^
In file included from q.c:2:0:
/usr/include/iup/iup.h:35:11: note: expected â€کint *’ but argument is of type â€کint’
int IupOpen (int *argc, char ***argv);
^
q.c:6:3: warning: passing argument 2 of â€کIupOpen’ from incompatible pointer type [enabled by default]
IupOpen(argc, argv);
^
In file included from q.c:2:0:
/usr/include/iup/iup.h:35:11: note: expected â€کchar ***’ but argument is of type â€کchar **’
int IupOpen (int *argc, char ***argv);
^
当我运行这个程序时,它崩溃了。然后我用gdb运行它,gdb告诉我程序崩溃了,这一行:
IupOpen(argc, argv);
我进行了rtfm和stfw,但我没有找到解决方案。
您应该调用IupOpen(&argc,&rgv),这就是gcc警告您的。
