Greetings All<br>
<br>
I'm having trouble getting my external to work, It compiles with no<br>
errors and has 1 warning when I do a make but it completes<br>
successfully see warning below.<br>
<br>
cc -export_dynamic -shared -lc -lm -DPD -O2 -funroll-loops<br>
-fomit-frame-pointer -fPIC -Wall -W -Wshadow -Wstrict-prototypes -Werror<br>
-Wno-unused -Wno-parentheses -Wno-switch -I../../../../pd/src -o<br>
sineq.pd_linux sineq.c<br>
/usr/bin/ld: warning: cannot find entry symbol xport_dynamic; defaulting<br>
to 0000000000000980<br>
strip --strip-unneeded sineq.pd_linux<br>
make[1]: Leaving directory `/home/rat/Documents/pd/code'<br>
Compilation finished successfully.<br>
<br>
I copy over the sineq.pd_linux to the pd-externals directory but when I<br>
try and add the external in PD it says "couldn't create" on the main<br>
console screen.<br>
<br>
Here's a link to the workflow of my thinking and what I'm trying to do,<br>
notice I have 4 float inputs and 1 signal output<br>

<br>
My external is a reproduction of the sinewave equation with 4 inputs<br>
that are floats and one output signal my logic is to have 4 inlets one<br>
for the frequency,amplitude,phase and vertical offset and an output for<br>
the created signal. Granted this isn't the final equation but this will<br>
help me understand how to create the full equation once done. If you<br>
want to see the full equation I'll be using here's a link to it below.<br>
<a href="http://dl.dropbox.com/u/6576402/questions/eq1.txt" target="_blank">http://dl.dropbox.com/u/<u></u>6576402/questions/eq1.txt</a><br>
<br>
Basically it's a 1 second periodic signal with the sample rate at 44100<br>
which the equation gives me control over the frequency,amplitude,phase<br>
and vertical offset, which will be controlled by a usb midi controller.<br>
<br>
Another question I have is what do I use for the t (time) for my final<br>
equation is that the t_sample object in PD? or do I need to create a<br>
for loop counting from 1-44100 for a 1 second 44100 sampled equation?<br>
like this link uses<br>

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