(OLPC build 602)
I have been trying a few things here and I stumbled
across a funny problem (this is quite specialised, so
I suppose only a few of you would know):

1. With Python, if I do

import gtk
import csnd

cs = csnd.Csound()
cs.Compile("myexample.csd")	

the csound compilation will fail with very unusual
syntax errors (which are not syntax errors at all)
(eg: "error: numeric syntax "11.1", line ...")

2. If I don't do

import gtk

Csound will happily compile my code.

Now this seems so weird that I can't understand
why it is happening.

Any clues why "import gtk" is causing this
behaviour?

thanks

Just to add a  little to say that this particular csound error is
issued when there is an incorrect numeric format, say
11.B or 11.1A. In here, if I only use integers, there is
no error, but all decimals are raising the error. Here's the
Csound code fragment that issues the error:


static int constndx(CSOUND *csound, const char *s)
{
     MYFLT   newval;
     int     h, n, prv;

     {
       volatile MYFLT  tmpVal;   /* make sure it really gets rounded to 
MYFLT */
       char            *tmp = (char*) s;
       tmpVal = (MYFLT) strtod(s, &tmp);
       newval = tmpVal;
       if (tmp == s || *tmp != (char) 0) {
         synterr(csound, Str("numeric syntax '%s'"), s);
         return 0;
       }
     }

(...)

}

Somehow the 'strtod'  conversion is getting it wrong.

But why only after 'import gtk', I cannot understand.

would this be the reason?

import gtk Changing the default encoding? Funny
I am not getting it on my other fedora systems (perhaps
because they are one version behind?).
