#1274 Problem with deken and gem

[Anonymous]

I have a problem on MacOS Sierra 10.12 with deken and gem, where gem reports "can't load library". Steps described below.

remove all pd installations
remove preferences (rm /Library/Preferences/org.puredata...)
install a fresh pd0.47-1
add gem 0.93.3 (deken installable)
add gem to the startup
(and in a second attempt even libdir and -libdir, as in http://puredatajapan.info/?p=2073).
Restart pd, and it gives "gem: can't load library".
try to create [gemhead] and it does not create.

Now, if I navigate to Contents/Resources/extra/Gem and doubleclick e.g. alpha-help.pd, [gemhead] is indeed created, but most other objects are not.

The same behaviour is seen both when placing pd in Applications and outside.

Any ideas?

• the Gem library is called Gem - starting with an upper-case G. the library loading mechanism is case sensitive, so loading gem (all lower-case) cannot work

• the Gem-binaries (on OSX) are 32bit only. You cannot use them with a 64bit Pd.

• raise the verbosity (both by adding the -verbose startup flag and by changing the log-level in the Pd-console) to see whether you get more interesting information

1) Sorry, should have been clear on that. I searched lowercase, but the rest were uppercase.
2) Didn't know about the 64/32 bit issue! This made the difference and it does indeed work in 32 bit.
3) Didn't do this now as 2) solved the problem.

I am not sure I ever saw it written that Gem would not work on 64 bit, but I might have missed it. Thanks for the very quick help on a Friday night!

well, Gem does (kind of [1]) work on 64bit, but there are no binaries available.

[1] but uses QuickTime for any image acquisition, which is not available on 64bit; so any 64bit version of Gem on OSX lacks some functionality...
