Re: [Cuis-dev] Larger mouse pointers on QHD screen?

Reported on Cuis, copying to vm-dev for follow-up. Replies should go to vm-dev.

Large cursor support is reported to be not working on 64-bit Linux VMs.
On Squeak, test this by enabling the "Use bigger mouse cursors" preference.

This is probably a build configuration issue. On a 64-bit interpreter VM
on Linux, larger cursors work as expected if and only if the xrender
development library is present in the build, e.g.

$ sudo apt-get install libxrender-dev

My memory jogger was this:

VMMaker 4.10.11

Enable large cursor support in the 64-bit image. Previous concern about
bitmap conversion is apparently no longer relevant, as #primitiveBeCursor
works properly on the 64-bit image (but tested only on little-endian).

Re: [Cuis-dev] Larger mouse pointers on QHD screen?

Hi all,

I just recompiled and tested cog branch head and confirm that neither 64 nor 32bits linux spur VM do honour the large cursor request.

The best would be to open an issue on https://github.com/OpenSmalltalk/opensmalltalk-vm.

Re: [Cuis-dev] Larger mouse pointers on QHD screen?

I wanted to check the legacy svn repository status, but what happened to it?

There have been some problems for a while; the board has been trying to get in touch with the owner of the domain etc etc.

The squeakvm.org server has been down. Until that is resolved you can check
out directly from the back end repository (which runs on a different
box) like this:

$ svn co http://180.235.36.229:8088/svn/squeak/trunk/platforms
$ svn co http://180.235.36.229:8088/svn/squeak/trunk/src

Aside from that, the build instructions at http://wiki.squeak.org/squeak/6354
are accurate.

I have not yet had a chance to check this out in the oscog code base,
but the original implementation has cmake checking for the xrender
development libs, and setting "#define HAVE_LIBXRENDER 1" in config.h.
Then in display_ioSetCursorARGB() in sqUnixX11.c, the code is active
if HAVE_LIBXRENDER is defined. There was also a VMMaker change to
activate this in VMMaker-dtl.298.

The oscog version of display_ioSetCursorARGB() has the necessary code,
but I don't see HAVE_LIBXRENDER being defined in my config.h, so my guess
is that it is something that needs to be backported to the build system
for oscog.

I'll try to follow up tomorrow, don't have time right now. But as a
quick check, maybe just add "#define HAVE_LIBXRENDER 1" manually to
config.h and see if it starts working?

Good to know!

since opensmalltalk is still using autotools, maybe something in configure.ac like

AC_CHECK_HEADER([X11/extensions/Xrender.h], [CPPFLAGS="${CPPFLAGS} -HAVE_LIBXRENDER "])
