From 97b1e368e51f2173577460c96a78f90347a4bf3b Mon Sep 17 00:00:00 2001 From: "Foad S. Farimani" Date: Wed, 17 Sep 2025 00:30:07 +0200 Subject: [PATCH] Fix HWND pointer casting errors on MinGW-w64 - Use uintptr_t for safe pointer-to-integer conversion of HWND - Fix Data32 call to pass address of tmp variable instead of casting integer to pointer - Resolves compilation errors with -Werror=int-to-pointer-cast on Windows cross-compilation Fixes build errors when cross-compiling with MinGW-w64 where HWND is a pointer type and direct casting between pointer and long of different sizes fails. --- src/XAppgroup.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/XAppgroup.c b/src/XAppgroup.c index b5642f3..6248c5d 100644 --- a/src/XAppgroup.c +++ b/src/XAppgroup.c @@ -337,7 +337,7 @@ Bool XagCreateAssociation(Display* dpy, Window* window_return, void* system_window) { #ifdef WIN32 - long tmp = *(HWND*) system_window; + long tmp = (long)(uintptr_t)(*(HWND*) system_window); XExtDisplayInfo *info = find_display (dpy); xXagCreateAssocReq *req; @@ -350,7 +350,7 @@ XagCreateAssociation(Display* dpy, Window* window_return, void* system_window) *window_return = req->window = XAllocID(dpy); req->window_type = XagWindowTypeWin32; req->system_window_len = sizeof(HWND); - Data32 (dpy, (long*) tmp, 1L); + Data32 (dpy, (long*) &tmp, 1L); req->length++; UnlockDisplay(dpy); SyncHandle(); -- 2.49.0.windows.1
