@whale-av Tried to copy all the externals from ye 'olde source code from Pd-extended to my own installation dir of Pd. That got rid of some errors. But some errors about " | " stayed. That's strange because that's a Vanilla logical operator.
Then I tried to compile ye 'olde source code from Pd-extended from source code. Got some error about pthread_create@@GLIBC
Maybe because pthread does not work anymore in modern C compilers? The current source code compiled without problems on my PC.
Anyway, I was about to give up and then I tried to install an old Linux Mint package (i.e. pre-compiled software). This luckily installed just fine. And guess what? The Moog patch works excellent.
There is a downside to all this, however. It's a shame that de kind developers of Pd make a version that does not work w/ our beloved patches anymore. Not even when you use the 'Find Externals' utility. And not even when you copy all the old Pd-extended externals to your current externals directory. A shame that ll that work on great patches from a few years ago go to waste.
Does anybody know how to compile the old Pd-extended on a mdern Linux system?
Now for that Pd-extended on a Raspberry Pi....
