I tried to use this
on Ubuntu/Maverick 10.10. It built find, but when I loaded the help
patch I got:

/media/share/code/lp/pdtest/pdtest.pd_linux: /media/share/code/lp/pdtest/pdtest.pd_linux: undefined symbol: lua_getfield
pdtest l s f b
... couldn't create

maybe a problem linking with liblua... I will look more closely at the build steps for linux when I get some time...

About the design, is this just meant to test compiled externals, or do
you see it as testing abstractions too?

.hc

I believe abstractions could be tested too, pdtest main limitation now is to only output and understand lists, symbols and floats but no signals. As a matter of fact, I don't see clearly how signals could be tested.
