compiling error in osmium/osm.hpp

[wiso]

Hello, I'm trying to copile the code with g++ (GCC) 4.6.2 20111027 (Red Hat 4.6.2-1) on fedora 16. I get this error. I'm following the instruction, the version is here:

that sounds like an incompatible version of geos. I'm compiling fine against 3.2.0. What does geos-config --version tell you?

I've 3.3.1

@joto it seems the C++ interface of geos was changed. The geos-guys recommend using the C interface - and now I know why.. I guess there are three poss ibilities:

1. rewrite osmium to use the C interface
2. fix the LinearRing-cast and possibly other problems with geos 3.3
3. use geos 3.2 for now

[wiso]

1. write an adaptor?

By the way, let me know when this problem is fixed, I'm really interested.

[joto]

If somebody sends me patches that make it work with geos 3.3 and geos 3.2 I'll integrate them. I don't have a machine with geos 3.3, so until I have one and need it myself I probably won't look into it (unless somebody pays me money to do that).

[MaZderMind]

joto/osmium#36 should fix it. I also updated my Makefile to work under fedora and debian.

[wiso]

Thanks, can you help me, I'm really ignorant on git. I see you have created a new branch. How can I download it? I'm following this instruction: https://github.com/MaZderMind/osm-history-renderer/blob/master/TUTORIAL.md

[MaZderMind]

Best thing would be to wait another day until joto reviewed and merged the patch and i've updated the importer to use the new osmium head.

[MaZderMind]

the patch has been merged, the importer now compiles under fedora 16.

[wiso]

sorry, but I tried to redownload it with these instruction https://github.com/MaZderMind/osm-history-renderer/blob/master/TUTORIAL.md and I get the same error as before

[MaZderMind]

This is how it looks to me: http://mazdermind.de/temp/fedora.png

[wiso]

in fact my error is about osm-history-splitter, not osm-history-renderer

[MaZderMind]

Sorry, I forgot to update the osmium reference of the splitter. Should work now.
