allow to pass user-defined manylinux1 docker image url about multibuild HOT 10 CLOSED

Have you tried enabling ccache? How much is the build sped up?

from multibuild.

I haven't. Will let you know

from multibuild.

Yes, an environment variable would be fine - any interest in making a PR for that?

from multibuild.

I mean yes, it would be fine, but ccache accomplishes exactly the same thing, and it results in overall less maintenance. My concern is that people will try to solve "using your own docker image" when they're really trying to solve "speeding up their builds."

I'll try the ccache first. I don't particularly want to maintain a fork of the manylinux1 docker.

@anthrotype Just so we're on the same page, all you have to do is add these lines to travis.yml:

Thanks!

@xoviat how do I check that the USE_CCACHE option is actually doing anything? Sorry, I'm not familiar with this ccache thing. I don't see much of a difference. My (linux) builds still take 7 minutes and a half on average (which I guess it's ok).

from multibuild.

Seeing that OSX took 12 minutes and the libraries were pre-compiled, I doubt the the "building libraries" phase of the build is responsible for more than two or three minutes. 7 minutes though is an appropriate time for multibuild to run; it's not meant for iteration.

fair enough, thanks.
