Hi Faust list,
I'm using libfaust.a from Faust version 2.0.a33, LLVM version 3.3 and
Csound version 6.05
I have a problem when using foreign functions in csound.
Victor Lazzarini has ported an on-the-fly compiler for faust scripts in
csound which works like this:
giInst faustcompile{{
magicFct = ffunction(float cbrtf|cbrt|cbrtl (float), <math.h>,"");
process = 27:magicFct;
}},"-vec -lv 1"
iF1, asig faustaudio giInst
and the other csound opcodes can use the signal (constant=3 here) elsewhere.
This code compiles but this one doesn't:
giInst faustcompile{{
magicValue = ffunction(int getValue(), "myLocalHeader.h","");
process = magicValue;
}},"-vec -lv 1"
LLVM ERROR: Program used external function 'getValue' which could not be
resolved!
no matter what I put instead of "myLocalHeader.h" (absolute/relative path
relative to current directory/to libfaust.a/to csound/bin/to usr/bin ...)
where myLocalHeader.h contains
int getValue(void);
const int value = 7;
int getValue (void){
return value;
}
I was told that faust2 was the source of a similar problem with max.
Is is also the case here ?
Note that
magicValue=fconstant(int value, "myLocalHeader.h");
and
magicValue=fvariable(int value, "myLocalHeader.h");
compile but the returned value is 0 instead of 7.
