I've got reports that AlgoScore doesn't work with the double version of
csound, and I wonder what I should take care of to make it work? Which
variables in the API are affected?

If you want to build it using the doubles version of the API, you need
to set -DUSE_DOUBLE in your compiler options (as well as
linking to the correct library).

Yes, I noticed that the new library was named libcsound64 instead of
libcsound, that was why my buildscript didn't find csound.

But now I got another problem, I use code like this to send score events
from AlgoScore to Csound:

    MYFLT *parms;
    int i;
    naRef vec = VECARG(2);
    int sz = naVec_size(vec);
    parms = malloc(sizeof(MYFLT)*sz);
    for(i=0;i

That is because MYFLT is set to be float not double. You will need
-DUSE_DOUBLE to set MYFLT to double. The insert_score_event() is
basically getting garbage as the pointer sizes don't match.

Oh, I didn't realize that I must set USE_DOUBLE also on my own sources.
I assumed that MYFLT would be defined as double if csound was compiled
with useDouble=1. Why else export MYFLT to the public API?

The scons build script could easily write a simple "#define MYFLT
double" to myflt.h and let csound.h include it. Then apps using the
csound API could just relax and use MYFLT and it would just work. Now I
need to check if csound was built with double precision by checking if
the library name is "csound" or "csound64" which is kind of ugly. And
does this work on MacOSX framework? Is there any other way to check if
csound is float or double?

I agree this perhaps needs a better solution. As for the OSX framework,
I have not yet decided which way I am going to package the doubles
build.
