Re: [CM] s7, undefined reference errors

[bil]

As Kjetil points out, you must have configured Snd
with --with-gmp or somehow created mus-config.h
with WITH_GMP set to 1.  That file does not come with
s7 (on the theory that people will read the instructions).
If you want to use gmp, you'll need -lgmp -lmpfr -lmpc.
If not, just delete whatever is in mus-config.h and
recompile s7, or run configure again (for Snd) without
--with-gmp, make clean, make.

Hi,

It seems like you compile s7 with "WITH_GMP" defined somehow.
Perhaps you have a mus-config.h file where WITH_GMP is defined?

I guess it compiles if you remove WITH_GMP from mus-config.h,
 or link in libgmp: -lgmp

[CM] s7, undefined reference errors

[James Hearon]

Hi,

I was trying to get back to looking at s7 as interpreter but I'm failing to 
compile for some reason.


I have s7.o, s7.h, and snd is working ok.  But I'm getting undefined ref errors 
trying to compile below and a little stumped what might be going wrong?  Seems 
like it's not finding something it needs.


//gcc -o repel_test repel_test.c s7.o  -Wl,-export-dynamic -lm -I. -ldl
#include "/opt/snd-16/s7.h"
int main (int argc, char **argv)
{
s7_scheme *sc;
sc = s7_init();
s7_load(sc, "/opt/snd-16/repl.scm");
s7_eval_c_string(sc, "((*repl* 'run))");
return(0);
}
