Hi:
DFB adopts Slave/Master model to handle multiple applications
(Fusion world),check Fusion documents.
If "gdk_open_display" failed , why not first identify this issue.
That's what I thought,:) Anyway, Mozilla over DFB is a nice stuff.
Look forward your cool work.

Hi,
We came to know that we have to pass --enable-multi for DFB configuration
and it needs fusion to be installed. We downloaded linux-fusion for this
purpose. It is compilling fine but gives a warning: implicit declaration of
function 'remap_pfn_range' in fusiondev.c . We also get:
Building Modules, stage 2
MODPOST
Warning: "remap_pfn_range" [fusion.ko] undefined
We are running FC3.
When we do MODPROBE fusion, it says error inserting fusion, unknown symbol.
Any help..??
Regards,
Siddharth
Hi,
We were able to install fusion by replacing the call to "remap_pfn_range"
with "remap_page_range". Now when we run any dfb app, it says "DirectFB
/core: Multi Application Core; Direct / Thread: Running Fusion Dispatch".
And, the executable runs fine. But our problem remains as it is.
1. If we try to run two dfb test apps(from remote machines), only one of
them runs, for the other it says "DirectFB / gdk_display_open: can not open
display: some versions may have problem".
2. If we run a app which uses execv() to execute another app, then the other
app come in separate DFB blue screen. Once we exit this app then we are
returned to our calling app.
In both the cases we want the Apps to run in same DFB screen. Is it possible
by installing fusion.? If yes, then what are the areas that we should look
for to achieve this..??
While installing fusion, we followed the instructions provided in README
except the above mentioned function call replacement. Do we need to do
anything else..??
We need this for plugin support in Mozilla over DirectFB.
Regards,
Siddharth
