Update build environment with CMake 2.8.8 or later

[rhyolight]

We are having cmake problems, which seem to be caused by using features of cmake that were added in 2.8.8. My feature request is to update cmake within build boxes to use the latest version of cmake.

[roidrage]

Have you considered manually installing a newer version in the meantime?

[rhyolight]

Yes, we're considering it, thanks for the suggestion.

Unfortunately, there doesn't seem to be a 64b CMake download available. So I would have to build it myself in the appropriate environment, upload it to S3, and download it from there to install on travis.

@roidrage Do you have any sense of how long it will be before Travis supports CMake 2.8.8? I'm not sure it's work the effort at this point, and we may end up reverting the new features from our build to get it green again.

Even better, 2.8.12. 👍

[rhyolight]

🎉 Awesome! How will I know when it's in production?

[kylog]

I was just voting for it. Didn't mean to get your hopes up ;)

[rhyolight]

Oh crap, I thought I saw a merged PR, but it was just a duplicate issue.

I would like to have cmake 2.8.12 out of the box as well, still having version 2.8.7 which is failing.

I think that a tool like cmake should be always up-to-date.

We are installing the package available for precise. The trusty one is 2.18.12, so until we upgrade to it (no ETA yet), this is unfortunately unlikely to happen. If anyone wants to take a shot at a custom recipe, we can help along.

[kobalicek]

Thanks for the answer!

Well, it would be nice if the right approach to install newest cmake is mentioned in documentation, would have saved me some time googling:)

[winterz]

yeah I really need cmake 2.8.9 or higher as well. so +1 from me on this request.

for the record, here' my before_install script for installing a cmake version that works for me on Linux and Mac: https://gist.github.com/10cc2741d466cbd8ff21

The older version of cmake is also breaking me; thanks @winterz for the workaround recipe!

[winterz]

you're welcome. I'm pretty sure the Mac workers now have cmake installed. so I updated my gist accordingly. https://gist.github.com/10cc2741d466cbd8ff21

Has anyone found a cmake 3 ppd or dpkg ?

My build depends on a few functions from 3.0 that I don't want to take out just because of Travis.

[jaredready]

Is there anything that people building on Ubuntu servers can do? Or are we just stuck waiting until they update to 14.04?

[BanzaiMan]

Unless there is a PPA that provides 64-bit image, you'd have to wait for Trusty support, on which we are working.

[BanzaiMan]

Closing this, as we've shipped Trusty support.
