centos 7 Missing Python Libs?

[hung135]

I followed the steps to build for Centos. Looks like I got all the way down to the end and got this:

@andrewseidl Any idea what's wrong here?

[dwayneberry]

@hung135 Did this occur while you were trying to build the dependencies?

if you are using centos 7 you can grab the dependencies already built and ready for you. Please see instructions here https://github.com/mapd/mapd-core#centos-7

[andrewseidl]

You might need to install package python-devel. I'll update the docs once I get a chance to reproduce.

That being said, as @dwayneberry mentioned, the easiest and quickest way to get up and running is to use the prebuilt dependencies.

[hung135]

Thanks guys.
@dwayneberry those were the directions I followed. Manualy many times. I must be missing something.
I also made a vagrant file just so I can destroy and re-create the evironment from scratch each time. https://github.com/hung135/vagrant_mapd_centos/blob/master/Vagrantfile. I'll keep at it until I get it to compile. Any other guidence would be appreciated.

[dwayneberry]

You do not need to manually build the dependencies at all, you can download for centos 7 a prebuild set of dependencies

from the instructions I point to above:

Next download and install the prebuilt dependencies:

curl -OJ https://internal-dependencies.mapd.com/mapd-deps/deploy.sh
sudo bash deploy.sh

These dependencies will be installed to a directory under /usr/local/mapd-deps. The deploy.sh script also installs Environment Modules in order to simplify managing the required environment variables. Log out and log back in after running the deploy.sh script in order to active Environment Modules command, module.

The mapd-deps environment module is disabled by default. To activate for your current session, run:

module load mapd-deps

To disable the mapd-deps module:

module unload mapd-deps
