From: Kristian Høgsberg Date: Sat, 23 Apr 2011 17:04:11 +0000 (-0400) Subject: compositor: Support loadable shells X-Git-Tag: 0.85.0~520 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=02ec0a5d3a42ff7ceff54acdcd57fad8c5573912;p=platform%2Fupstream%2Fweston.git compositor: Support loadable shells The shell module is responsible for implementing the higher level compositor behavior. We default to the desktop-lite shell built in to the compositor. --- diff --git a/compositor/Makefile.am b/compositor/Makefile.am index 47f8091..7855feb 100644 --- a/compositor/Makefile.am +++ b/compositor/Makefile.am @@ -8,8 +8,10 @@ AM_CPPFLAGS = \ AM_CFLAGS = $(GCC_CFLAGS) +compositor_LDFLAGS = -export-dynamic compositor_LDADD = \ - $(COMPOSITOR_LIBS) + $(COMPOSITOR_LIBS) \ + $(DLOPEN_LIBS) if ENABLE_DRM_COMPOSITOR drm_compositor_sources = compositor-drm.c tty.c evdev.c diff --git a/compositor/compositor-x11.c b/compositor/compositor-x11.c index fe8038b..2f02ec3 100644 --- a/compositor/compositor-x11.c +++ b/compositor/compositor-x11.c @@ -448,7 +448,7 @@ x11_compositor_handle_event(int fd, uint32_t mask, void *data) output = x11_compositor_find_output(c, focus_in->event);
