@aashish24 @doutriaux1 can you take a peek at https://travis-ci.org/PCMDI/pcmdi_metrics/jobs/109982706#L4194-L4204

CMake Error: Could not find CMAKE_ROOT !!!


CMake has most likely not been installed correctly.
Modules directory not found in
/home/travis/build/PCMDI/_build/PCMDI_METRICS/Externals/bin
CMake Error: Error executing cmake::LoadCache(). Aborting.

It would seem that there is a CMake install failure that is tripping over our travis testing..

@aashish24 what is a 1 return code from the CMake install mean? As it's nonzero is that indicating a build issue?

returning from build subshell with code: [1] ; # From install_metrics.bash
installed CMake version = 3.4.3

This is what we're getting on travis currently - it's also happening on linux builds..

[durack1]

@aashish24 can you please take a look at this ASAP.. It's causing problems downstream PCMDI/pcmdi_metrics#307

[durack1]

@gleckler1 @doutriaux1 pinging you here - this is relevant for PCMDI/pcmdi_metrics#307

[durack1]

@aashish24 it would seem that after a successful CMake install, it's not adding itself to the path, and consequently bombs

@aashish24 @doutriaux1 is this a known CMake bug - and if so, should we be using the CMake 3.4.x version instead?

[aashish24]

@durack1 yeah I believe CMake does not add itself to path which I think is the right behavior. We should set the path correctly. I will have a look at it unless someone else wants to take it.

[durack1]

@aashish24 if you could ascertain the best fix here that would be great.. I did test with CMake 3.4.x and that seemed to work, so I do wonder whether this behavior has changed in the later releases?

It'd be great to get a quick response to this too, we're hoping to get some folks up and running remotely with UV-CDAT and they're hitting issues with the install..

[durack1]

@aashish24 I've just tried to update CMake 3.4.3 to see if this fixes the problem, and it doesn't so it would be great if you can offer a solution here - the PR is at PCMDI/pcmdi_metrics#316 - it's a downstream problem in another project

[doutriaux1]

Conda switch solves thia, just uae conda to gwt uvcdat on travis
