Re: [bp-dev] Completion of loading and using sound-object prototypes

Dear Bernard,

Thanks for all of this work!  Having -mi files working will be awesome!

I've checked out your branch of the code.  It compiles fine but when I 
try to test creating an HTML image file, I get these warnings on the 
console:

‘CANVAS_header.txt’ is missing!
‘CANVAS_footer.txt’ is missing!

Have you committed these files yet?

I created temporary header and footer files containing these lines:

---- HEADER ----\n

---- FOOTER ----\n

But now I get a crash during CreateImageFile():

Creating image file: NadakaPOc5SSSOc4PGRSOc3NO_image_1.html
Current working dir: 
/Volumes/iMacSystem/Users/anthony/Projects/BP3_graphics_branch/bolprocessor
bp(65929,0x7fff77df7000) malloc: *** error for object 0x7fff54d44ee0: 
pointer being realloc'd was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

I haven't traced the error yet, but my guess is that it happens while 
reading the file "CANVAS_header.txt".  Probably in this code:

     else {
         while((number = getline(&someline,&length,thisfile)) != -1) {
             fputs(someline,imagePtr);
             }
         fclose(thisfile);
         fputs(word,imagePtr);
         }

The variable someline is uninitialized.  The error message suggests that 
a buffer allocated with malloc() should be passed.  I'm not sure where 
the getline() function is coming from.

This is the commandline that I am using:

./bp produce -d --midiout Nadaka.mid -gr data/-gr.Nadaka1 -se 
data/-se.hamsad --traceout Nadaka.txt

Thanks!

Anthony
