libsndfile and Photoshop

Hi

i'm trying to compile a 64 bits version of my 32 bits plugin which works ok on CS2

i came to a point where when i add in my code any libsndfile related function (sf_open, sfinfo, sf_read_double) the plugin don't show anymore on the plugin list.

If i remove them, the plugin shows back.

So how come ?

I've tried to put a boolean before the code to false, and modify to true when the function is used but it doesn't work. The only thing that works, is when i put "if (false) {}" between the functions.

I don't understand how Photoshop works: Is it testing the plugin in some ways ? If so, the code part where i put a boolean to false, should not work, though should make the plugin appear...

please enlighten me.
