Subject[Cs-dev] Gabriel's opcodes
I have been reviewing the code, and the functions tabplay_k and
tabrec_k contain a serious error I do not understand

        MYFLT *fno;             /* **** THIS IS AN ERROR **** Uninitialised */
        if ((*fno = (int)*p->kfn) <= 0 || *fno > csound->maxfnum || (ftp = ftnp2find(csound,fno)) == NULL) {
          /*sprintf(errmsg, Str(X_315,"Invalid ftable no. %f"),*p->kfn); */
          sprintf(errmsg, "Invalid ftable no. %f",*p->kfn);
          return perferror(errmsg);
        }

*fno is not a valid location and this may crash in an arbitrary way.
Does anyone understand what it is supposed to do?

SubjectRe: [Cs-dev] Gabriel's opcodes
That looks like a k-rate function table number, so you can access
different tables in performance. I suppose fno should get its
value from one of the opcode arguments. The code seems to test to see
if the function table number is valid and if the table exists.

SubjectRe: [Cs-dev] nub building csound5 fltk
Hi,
The file FL.h is found, since the thing builds, what's happening is the 
library isn't so the problem is during linking. The library is called 
libfltk.a.
Have you built fltk? Or did you install an rpm package?

SubjectRe: [Cs-dev] nub building csound5 fltk
it seems to have found /usr/lib/libfltk.a  all right, the default distro 
that you apt-get from ccrma wasn't working. having built fltk in 
/usr/local/lib with the options --enable-threads and hiding the 
apt-getted ccrma versions of fltk stuff got me to here:

gcc "-Wl,-Bdynamic -shared" -o libbabo.so Opcodes/babo.os -L. -L. 
-L/usr/lib -L/ usr/local/lib -L. -L. -L/usr/local/lib/python2.3/config

the quotes are messing up this line and so is the space inside 
-L/usr/local/lib i don't know scons well enough to figure where these 
artifacts come from....

You have an old version of scons; after upgrading it this error should be
fixed (a similar problem was reported by Dave Phillips).
