LD_LIBRARY_PATH and Dreamhost

[Emanuel Carnevale]

Hi all,
Does anyone know how to set a path on Dreamhost?
I have a custom install of ImageMagick and rmagick gem that works
flawlessly from irb and the shell, but it doesn't work under
passenger.

I've tried ENV['LD_LIBRARY_PATH']='/home/
username/local/lib' in my config.ru file, but it doesn't yield any
good result..,

any clue?

Thanks in advance,
regards
Emanuel

I don't know how Passenger handles environment variables but it's
possible SetEnv would work from a .htaccess file....

Let us know if it works.

In my experience, SetEnv *won't* work, since those values are only
picked up by processes forked by the Apache worker processes, rather
than the master (which is in turn the parent of the Passenger parent
process).

The more reliable solution, in my experience, is to set the
PassengerRuby path to a wrapper script which sets LD_LIBRARY_PATH (or
any other needed environment vars) before exec'ing your choice of Ruby
runtimes.

Hmm, that's too bad. The PassengerRuby setting can only be set once
for the entire Apache. We could do that for customers using our
DreamHost PS servers, but not on shared servers (since Apache settings
are shared across several customers).

If one of our customers is interested, on a DreamHost PS server, and
willing to work with us on it, we can get something going.
