Greetings All
I'm having trouble getting my external to work, It compiles with no
errors and has 1 warning when I do a make but it completes
successfully see warning below.
cc -export_dynamic -shared -lc -lm -DPD -O2 -funroll-loops
-fomit-frame-pointer -fPIC -Wall -W -Wshadow -Wstrict-prototypes -Werror

sineq.pd_linux sineq.c
/usr/bin/ld: warning: cannot find entry symbol xport_dynamic; defaulting

strip --strip-unneeded sineq.pd_linux
make[1]: Leaving directory `/home/rat/Documents/pd/code'
Compilation finished successfully.
I copy over the sineq.pd_linux to the pd-externals directory but when I
try and add the external in PD it says "couldn't create" on the main
console screen.
Here's a link to the workflow of my thinking and what I'm trying to do,
notice I have 4 float inputs and 1 signal output

My external is a reproduction of the sinewave equation with 4 inputs
that are floats and one output signal my logic is to have 4 inlets one
for the frequency,amplitude,phase and vertical offset and an output for
the created signal. Granted this isn't the final equation but this will
help me understand how to create the full equation once done. If you
want to see the full equation I'll be using here's a link to it below.

Basically it's a 1 second periodic signal with the sample rate at 44100
which the equation gives me control over the frequency,amplitude,phase
and vertical offset, which will be controlled by a usb midi controller.
Another question I have is what do I use for the t (time) for my final
equation is that the t_sample object in PD? or do I need to create a
for loop counting from 1-44100 for a 1 second 44100 sampled equation?

PS: I'm compiling on ubuntu 10.04 using gcc
Sorry for the link / information overload. After going over the
d_osc.c, bassemu.c and the pan~ tutorial I'm a little stuck and not sure
what's causing the issue.
