Not trying to hijack this thread into a different subject, I was messing with the external in order to understand how it works. I got my mods on, compiled it, all ok.
But how can I load it? pdextended always load a default "filetext", I even started with the -nostdpath but no luck. It doesn't load mine. I'm launching pd from the same dir as the filetext.pd_linux... What's the correct way to test externals in these conditions..? Some help? Best regards to all, Pedro p.s. also tryed >pdextended -path textfile.pd_linux (nothin'..)
