Not compatible with PROJ.4 v6.0.0 about rgeo-proj4 HOT 18 CLOSED

One of our team hammered at this yesterday.

The take home was to patch. He wrote:

Used brew edit proj and added the following code:

  head do
    url "https://github.com/OSGeo/proj.4.git"
    depends_on "autoconf" => :build
    depends_on "automake" => :build
    depends_on "libtool" => :build
  end

Executed brew reinstall proj -s and then bundle pristine. rake db:create worked.

While it's specific to our software he posted a precise list of commands for a clean install on os x, I've added a gist here- https://gist.github.com/mjy/02fc0bec94a3f0f4da792baad0df1a3f

from rgeo-proj4.

Thanks for reporting this.

This appears to be a band-aid, but not a long-term solution:

OSGeo/PROJ#836

from rgeo-proj4.

@sethdeckard Thanks much for the pointer, it resolved our issues as well. We were working with completely clean systems, so it wasn't cache related.

Moving forward ket me know I can help test things out somehow here, we really appreciate everyones work on this.

from rgeo-proj4.

I have created a Gist for anyone looking to get rgeo / proj4 working on a Mac with Homebrew - see https://gist.github.com/peterwake/b0fff0c5c018c655c6d5a4aee86aa8ef

from rgeo-proj4.

Any chance of getting support for the newer version? It's not just macOS machines that use this gem.

from rgeo-proj4.

Fixed by #10. Version 3.0.0 is now out which uses v6.2+. Thanks for the patience everyone!

from rgeo-proj4.

It seems this is now impacting a system setup with brew install postgis (gets 11.2), could that be right? We're getting "Coordinate system 'proj4' is not supported'? from the rgeo-2.0.1 gem.

from rgeo-proj4.

To follow up, switching back to 5.2.0 eliminates the first error, but we hit a second:

PG:UdefinedFile: ERROR: could not load library "/usr/local/lib/postgresl/postgis-2.5.0.so ... Library not loaded: /usr/local/opt/proj/lib/libproj.15.dylib. Seems we only have libproj.13.dylib via this route now. Exploring installing proj from source, but clearly need some other fixes.

Update

For others hitting this I think this ultimately let us use @sethdeckard's solution: brew link --overwrite proj, our system was obiously not "clean".

from rgeo-proj4.

Anyone have any suggestions on how to get this gem working with alpine linux 3.9? In alpine proj4 is only available in the edge/testing repo and I can't scope to a different version (currently 6.1.0).

from rgeo-proj4.

@mjy I've been hitting the same PG:UdefinedFile error and can't get the link command to change anything. I've tried starting fresh, messing with the postgis install, and several other things. Is there a reproducible set of steps I can follow to fix this?

from rgeo-proj4.

@MaxMartiFoundry I don't have the full list of steps, sorry. IIRC its something like: nuke as much as possible with brew, also nuke your geo gems. Follow Seth's steps, then my link step, then re-install the gems.

Again, sorry this is not very technical. If I hit it again I'll document explicitly here.

from rgeo-proj4.

I can't get this to work. I did this:

brew uninstall proj
brew tap sethdeckard/proj
brew install sethdeckard/proj/proj
gem uninstall rgeo-proj4
gem install rgeo-proj4

Am I missing a step? Can some other proj installation be on my system, how do I find which one it's linking to?

from rgeo-proj4.

Hi, all. Any solution on this, except downgrade?

from rgeo-proj4.

@baramik The patch mentioned above is technically not a downgrade, it's just delaying the inevitable as far as I understand it- i.e. it enables the use of proj 6.2.

from rgeo-proj4.

Hi @teeparham
Is there any plan to provide a long-term solution by replacing proj_api.h ?
Is it at least possible ?

from rgeo-proj4.

Looks like brew is starting to install proj version 7.0. The patch mentioned above will no longer work (as the patch itself warned about). Should still work if you force 6.x, though.

from rgeo-proj4.

Hello, Do you plan to support version 7?

from rgeo-proj4.

Looks like brew is starting to install proj version 7.0. The patch mentioned above will no longer work (as the patch itself warned about). Should still work if you force 6.x, though.

The patch above and @peterwake gist still works with 6.3.2.

As of today (May, 20 2020) it worked with the osgeo-proj.

The only changes are:

brew edit osgeo-proj
brew install osgeo-proj -s
gem install rgeo -- --with-geos-dir=/usr/local/Cellar/geos/3.8.1_1 \
--with-proj-dir=/usr/local/Cellar/osgeo-proj/6.3.2
gem install rgeo-proj4
