Hi List!
I had the same problem "The ordinal 50 could not be found in jpeg.dll".
The problem was, when starting my app from eclipse, i got the
ordinal-50-error above, but when starting from commandline everything was
ok.
the problem was, that eclipse at startup loaded another jpeg.dll from the
jdk directory per default. this jpeg.dll has nothing in common with the one
from SDL but its name. nevertheless, when running my app from eclipse, the
system reckognizes, that there is a jpeg.dll loaded yet and tries to find
the function with ordinal 50, but cannot find it, because in the loaded
jpeg.dll form the jdk directory there are less than 50 functions.
i solved the problem by explicitly loading my SDl-related jpeg.dll in my
application by calling
System.load(new File(".").getCanonicalPath() + "/dlls/jpeg.dll");
(the argument has to be the absolute path to the dll in question.)
this way, my app also works when started from eclipse!
maybe that works..
have fun
