hi!<br>
I changed inelegantly the configure script to get a vm-display-fbdev
and...<br>
...came to understand, that there are more issues with Cog + fbdev
(below is the make output).<br>
<br>
Now I wanted to put it in a general question: are there efforts to
maintain the vm-display-fbdev for CogVM? I guess there is little
need for it in general, but in some cases it is nice to have (for
building embedded or tiny systems the linux framebuffer is nice;
sleak, confless).<br>
Can anybody help me? Thanks.<br></div></blockquote><div><br></div><div>The Cog VM is derived from Qwaq/Teleplace (a defunct company that developed Croquet for business). There the display system was extended for additional host window support. That support was implemented for vm-display-X11 and vm-display-null but not for vm-display-fbdev. You'll need to implement similar stubs that you'll find in the vm-display-null, since most of these primitives don't make sense/don't do anything in the context of fbdav (which takes control of the frame buffer and is hence always full-screen). When you've implemented the stubs please send me the code so I can implement.</div>

<pre>hello everbody,
I want to build the CogVM (latest revision from <a href="http://squeakvm.org/svn/branches/Cog" target="_blank">squeakvm.org/svn/branches/Cog</a>),
but with the vm-display-fbdev module (for linux framebuffer device) as default.
Now I am a bit stuck in understanding the make process. Just leaving out the "--without-vm-display-fbdev" as argument to the configure script does not lead to it being included in the compile process.
Also I don't find the exact location in the scripts, where to tell that the vm-display-fbdev should not only be included, but shall also replace the default display-X11-module.
Thanks for your help,
best regards
Michael
