GEOS not found after install

[joelmahoney]

Hi @cyberdelia. I'm having trouble installing postgis + RGeo on Heroku. @deafbybeheading recommended this buildpack. It seems to install correctly but after install RGeo can't find GEOS. Any suggestions?

This was an order of operations problem: I transferred an old database to the app before installing heroku-geo-buildpack. If I create the postgis extension in the database, then deploy to install heroku-geo-buildpack, and then import the pg_dump, it works fine. Thanks!

Hi, I'm not sure if this is the right place for this and I'm happy to take it elsewhere, but I've tried everything to get this working and can't make it work.

Like @joelmahoney it seems to install okay, but RGeo can't see Geos from a console. I've even tried reimporting my database after the buildpack was intsalled and no dice.

It does seem like Geos and Proj4 are getting installed, but that bundler is not compiling Rgeo with the correct paths to them.

± heroku run bash
~ $ ls vendor/
assets  bundle  gdal  geos  heroku  proj  ruby-2.1.0

And I can manually recompile the gem from the heroku bash prompt and get it working, but this change doesn't stick.

~ $ gem uninstall -i /app/vendor/bundle/ruby/2.1.0 rgeo

You have requested to uninstall the gem:
    rgeo-0.3.20

rgeo-activerecord-1.0.0 depends on rgeo (~> 0.3.20)
If you remove this gem, these dependencies will not be met.

I must be doing something wrong since it seems to work for everyone else... can anyone help me out? Thanks in advance.

Gemfile:

gem 'activerecord-postgis-adapter', '~> 1.1.0'

rurabe, I ran into this problem and found that this fork fixed the problem in one of it's commits

https://github.com/Tekco/heroku-geo-buildpack

[solenema]

I have the same issue as @rurabe and tried to use this forked version but I have still the same problem. RGeos is not supported.

[harmdewit]

Did anyone else manage to fix this one way or another?

[davidrleonard]

I know this isn't super valuable, but wanted to ping this thread and see if anyone watching has had some luck fixing the issue? Above recommendations did not work for us.

[cyberdelia]

After a long investigation, I believe this is due to a bug with rgeo ext compilation and libgeos 3.4.2, see: rgeo/rgeo#75

[mgiraldo]

pinging to see if any fixes have been found

anyone?

[harmdewit]

Nope, couldn't fix it yet

btw: finally worked for me. see: https://github.com/cyberdelia/heroku-geo-buildpack/issues/20#issuecomment-50666187

[charlesdg]

Still have this issue. Anyone found a solution?

[cyberdelia]

I move some files, so that cedar-14 packages are chosen by default, this should provides a workaround (and eventually break for people stolen cedar-14). A better fix coming up after the holidays.
