Add back-linking to libEGL

It seems EGL drivers should link back to libEGL.so on Cygwin.  Could you try again with this patch?

libEGL should have been built in src/egl/main/.  Does it not exist or does it have a different suffix?

Comment 7 Chia-I Wu 2010-05-18 12:22:32 UTC
I am not sure how to proceed from here.  Does progs/demos/ build on cygwin?  If it does, I suppose progs/egl/ should too.
Comment 8 Vinson Lee 2010-05-18 19:44:15 UTC
demos successfully builds on Cygwin.

fix building EGL demos by ignoring LIB_DEP

The GNU make manual says that a suffix rule cannot have any prerequisite.  It seems $(LIB_DEP) in progs/demos/Makefile is simply ignored.  Could you see if this patch helps?  It is a workaround instead of a fix.

give cygwin libraries the correct suffix

This patch tries to fix the issue by fixing the library suffix in cygwin.  This is a real fix, but I could not test it.  If it is not too much trouble, could you see if this fixes the issue too?  I would like to apply this patch instead of the workaround above.

The workaround patch gets progs/egl building.

I did a 'make realclean; autogen.sh; make'. This patch gets progs/egl working too. It also stops the unnecessary rebuilding of some DLLs on incremental makes as well.
