Date: Sun, 09 Nov 2014 15:38:00 -0000 [thread overview] Message-ID: <545F8A73.6010206@alice.it> (raw) From another application I have an issue with libX11 which I can reproduce with the following STC, $ cat getch_test.c /* gcc getch_test.c -lX11 -o getch_test.out DISPLAY=127.0.0.1:0.0 ./getch_test.out */ #include <stdio.h> #include <stdlib.h> #include <X11/Xlib.h> #include <X11/Xutil.h> #include <X11/Xos.h> #include <X11/Xatom.h> #include <X11/keysym.h> Display *dis; Window win; int fun() { XEvent event; char c; printf("1\n"); while(1) { printf("2\n"); XNextEvent(dis, &event); printf("3\n"); if (event.type == KeyPress) { c = (char) XLookupKeysym(&event.xkey, 0); return (int) c; } } } int main() { dis = XOpenDisplay(NULL); win = XCreateSimpleWindow(dis, RootWindow(dis, 0), 1, 1, 500, 500, 0, BlackPixel (dis, 0), BlackPixel(dis, 0)); XMapWindow(dis, win); XFlush(dis); printf("Press a key:\n"); fun(); /*Sleep 5 seconds before closing.*/ //sleep(5); return (0); } Running it, one gets $ DISPLAY=127.0.0.1:0.0 ./getch_test.out Press a key: 1 2 HANGS it does not print "3", so it seems it does not return from XNextEvent(dis, &event); I am not an X11 expert, so it could be I am doing the wrong things but the same code runs fine on OSX+XQuartz and GCC-4.9.1. For completeness, I start the Cygwin X server with a link on status bar (W7+Cygwin64) whose target is: C:\cygwin64\bin\run.exe --quote bash -l -c "rm -rf /tmp/.X*; XWin -multiwindow -clipboard -silent-dup-error 2>/dev/null &" Ciao, Angelo. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
