Created install script for Ubuntu:18.04 Bionic

[jendrusk]

I was trying to install Valhalla on Bionic and I faced several issues... finally I made it, so this is my script - you can link it in your documentation - could be handy. You can test it using lxc container with ubuntu:18.04 - after few minutes you should get ready to use container :)

Might also want to add this in the data building section:

ln -s /usr/lib/x86_64-linux-gnu/mod_spatialite.so /usr/lib/x86_64-linux-gnu/mod_spatialite

This issue describes the need for special handling for sqlite load_extension in 18.0.4: #1437

[kevinkreiser]

@dnesbitt61 about mod_spatialite, maybe we should have the code do the fallback instead of forcing the user to create a symlink. this would be nicer imho and would be a small amount of code i think!?

[dnesbitt61]

not sure how to do this, but if you walk me through it I can try later. It just seemed that others already have gone through the process of creating the symlink so figured that was the desired approach.

[kevinkreiser]

@dnesbitt61 we would just need to add a retry in the if that checks the return code of the module loading query. i'll open another issue for this! dont let me stop you guys merging this.

[dnesbitt61]

@jendrusk thanks for the PR! I am going to move this to the scripts directory and place a link to it in the Readme.

[jendrusk]

I'm glad I could help. :)

[erictheise]

Your script works flawlessly @jendrusk. Big thanks to you for contributing it to the project!

[erictheise]

I may have spoken too soon. Following the steps in Running I experience

$ valhalla_service valhalla.json 1
valhalla_service: error while loading shared libraries: libprime_server.so.0: cannot open shared object file: No such file or directory
$

although it's sitting right there in /usr/local/lib/.

[kevinkreiser]

Is that location on your LD_LIBRARY_PATH?

[ptodorov0]

Had the same problem on a fresh 18.04. Installed using the Ubuntu_Bionic_Install.sh script. Fixed it by running
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/

Thanks for the suggestion, @kevinkreiser

It will be nice if this fix is added to the Ubuntu_Bionic_Install.sh
