Compile error for ubuntu 12.04: boost/make_shared.hpp missing

[wstrinz]

I've been trying to install the gem on ubuntu 12.04.

The best luck I've had so far is using the ppas on https://github.com/mapnik/mapnik/wiki/UbuntuInstallation, but the gem's failing to compile now.

I've tried with gem install ruby_mapnik, and cloning the repo and running rake. Both give me

Building native extensions.  This could take a while...
ERROR:  Error installing ruby_mapnik:

I'm guessing based on the fatal error: boost/make_shared.hpp: No such file or directory line that there may be a problem with my libboost installation, but I'm not sure how to go about attacking it.

Using ruby-2.0.0-p247 by the way.

Thanks!

It looks like you don't have the boost development headers installed. Try sudo apt-get install libboost-dev

[wstrinz]

Thanks for the quick reply :)

I've installed libboost-dev as part of the instructions on the ubuntu installation page already, but since I tried a couple of different ways of getting it to that point I may have screwed something up along the way. I purged everything and built mapnik from the v2.1 source, and now I'm getting a different error (installing from the git repo) complaining that agg_trans_affine.h is missing:

Looks like its from libcairo, so i tried apt-get install libcairo2 libcairo2-dev python-cairo python-cairo-dev libcairomm-1.0-1 libcairomm-1.0-dev, but no luck.

Progress!

Sorry about the trouble. I would recommend you use mapnik v2.2.0 from PPA (which will bring in boost 1.49) + ruby-mapnik from master here. If you hit any problems with that combination then it should be easy for me to fix on the spot.

[wstrinz]

Not at all, thanks for helping. I've reinstalled from the PPA, and I'm able to install the gem, but when I run the demo script, it seems to fail because it can't load proj4

I tried installing libproj-dev, libproj0, proj-bin, and proj.

[wstrinz]

It is working fine with most other mapnik functions though, so feel free to close this issue.

Thanks for all your help!

[springmeyer]

Lacking proj4 support -DMAPNIK_USE_PROJ4 is a compile time option in Mapnik. This should be enabled in the v2.2.0 Mapnik PPA. So perhaps you ended up installing Mapnik from source? If so, then you need to recompile mapnik after installing libproj-dev. But yeah, it is an optional feature, so not totally necessary.

[wstrinz]

Tried again on a clean ubuntu installation, everything went fine. My advice to anyone coming across this: don't try to install mapnik from the source.
