I am also very interested in externals in Rev. From little I know so
far you need a different external, not only for each platform, but for
each (major?) system version. To me this is understandable, as
different systems work differently, so the interfacing part with the
system needs to be different, as well as possibly the numbers and
sorts of variables you'll be passing to/from that particular system.
There is an excellent REV Tutorial on Externals :
http://www.runrev.com/developers/tutorials/advanced-externals-part-1/
There is also a part 2. You can download the 'External Creator V3'
stack which will create the external for you, if you have the
compilation of the code (in C , C++ and others) done. I don't know if
you can use Java.
I managed to comple the first examp[le (rnahello) but get a compile
error on the second example (rnaeffect) which I am not able to fix
because my barely existing C knowledge. After exactly copying in the
rnaeffect example from the tutorial I had some errors. Some had to do
with the 'exeption handling', which I had to change in the preferences
I think. Then I was down to 1 error, which persists.
