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;
}
我这样编译
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);
^
当我运行程序时,它崩溃了。然后我使用 gdb 运行它,gdb 告诉我程序在这一行崩溃了:
IupOpen(argc, argv);
我 rtfm 和 stfw 但我没有找到解决方案。
