Ah.. it's config data. It's not supposed to need that. But when I added it I
got a
different error:

Adding lib py2html

That didn't work so I tried this:
skaller@felix:~/felix$
LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/felix/felix-1.1.7dev/lib/rtl/
webserver
and that actually works!
So there are two problems:
(1) I incorrectly assumed the default (builtin, hardcoded) config would
work, but there's a bug, the plugins aren't included in the config
at the point they need to be. Woops!
(2) On Mac, /usr/local/lib is on the default search path for shared libraries.
On Linux it isn't (at least on the Ubuntu install at Felix-lang.org).
Adding LD_LIBRARY_PATH is required, however not just for the plugins,
but also the Felix libraries, since the plugins depend on them.
It's kinda-weird this works on my Mac WITHOUT DYLD_LIBRARY_PATH
since the Felix libraries are still in /usr/lib/felix/felix-1.1.7dev/shlibs
which
is not on the search path. No idea why but I am guessing great EVIL:
the dylibs are remembering the build/release/lib/rtl libs they were linked
against, they're not linking against the installed ones at all.
Oh yes. Its EVIL: I deleted the build and ..

Adding lib py2html
Dynamic linkage error
filename: py2html.dylib
operation: dlopen
what: dlopen(py2html.dylib, 2): Library not loaded:
build/release/lib/rtl/libflx_pthread_dynamic.dylib
Referenced from: /usr/local/lib/py2html.dylib
Reason: image not found
Ok, I'll have to think how to fix this. Dynamic linkage is a pain!
[Especially as the webserver itself is statically linked and probably
already has the code from libflx_pthread linked in .. statically]
