Hi list,
It seems expr isn't compatible with the libdir format. The code in expr_new of
vexp_if.c checks for unprefixed creator names, so if the user typed
"expr~/expr~" or "extra/expr~" or even
"the_libdir_that_I_put_in_my_patch_directory/expr~", the logic defaults to
creating an expr_class instead of an expr_tilde_class. It also outputs an
error.
Also, the error it outputs has a bug itself-- there is no corresponding
variable for the %s in this line:
post("expr_new: bad object name '%s'");
That will often cause a crash on 32-bit systems. I wasn't able to crash on a
64-bit system, although that %s will output a bunch of garbage characters to
the Pd window.
Obviously expr (and probably a lot of other code) expect the creator to be the
same as what the class author specified in the setup routine. So Pd should
deliver that symbol without the libdir prefix to the *_new function for that
class.
I tested on Pd 0.43 from Sourceforge on a 32-bit Wheezy machine, plus Pd-l2ork
which forked at 0.42. Has Pd Vanilla addressed this problem since then?
