The recommend usage is make If cmake was found with ./configure it will use it automatically if you do make, if it was not found it will use the legacy make Barry On Apr 22, 2012, at 10:19 AM, Dave Nystrom wrote:

OK. I'll mail the configure.log to petsc-maint. But this did not start out as a configure problem - I was just asking for a recommendation on usage. And the response you cite below was to Aron before I received your response.

I have cmake on my system but configure.log does not document that approach.

We did not find it. This is a configure question, and should be mailed to petsc-maint, not the dev list.

What is your build command to build petsc with cmake?

make

I use the CMake build because it's the fastest, though it requires you to have CMake installed on your system.

At the end of configure.log, there are two possible ways to build petsc-dev that are specified. Which is the recommended way to build - using make or using python? I have been using make.

Also, one is labeled as legacy and one is labeled as experimental. That gives the impression of having a choice between an old, archaic method or a new, experimental approach. Should one just be labeled as production?

Thanks,

Dave
