Basicly its a problem that gambas2 is v4l1 and now most distros use v4l2
So you need to have v4lcompat and preload it like this
for 64bit
LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so (application name)
for _86
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so (application name)
In code you can try something like this
Public Sub Main()
DIM myname AS String
DIM myarch AS String
SHELL "uname -p" TO myarch
'frmMain.Show
IF Application.Args.Count <> 2 THEN
IF InStr(myarch, "64") <> 0 THEN
myname = "LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so " &
Application.Name & " v4l"
PRINT "Launch program with 64 bit v4l1compat.so"
ELSE
myname = "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so " &
Application.Name & " v4l"
PRINT "Launch program with 32 bit v4l1compat.so"
END IF
PRINT myname
SHELL myname WAIT
QUIT
ELSE
IF Application.Args[1] <> "v4l" THEN QUIT
'else continue
frmMain.Show 'this is the form to start.
END IF
End
This will relaunch your program preloading v4lcompat
Benniot said it is fixed in version 3
