Re: Compile 4.7.1 problems
There's a couple of things about this script, useful as it is:
1. IIRC it downloads the minimal set of prerequisites. Wouldn't be bad
to have it optionally grab the optional prerequisites.
2. It uses wget. At this point I'm not sure if wget or curl are more
common; on OS X I had to rewrite the wget commands as curl commands.
I work on a bunch of large open source projects with many
prerequisites, of which Slicer is a prime example (http://slicer.org).
Slicer (and any projects my lab originates) use CMake, and
prerequisites are handled by a CMake macro that downloads, configures
and builds all prerequisites. It also subsumes a lot of the nuts &
bolts of autoconf system-sniffing into the 'it just works' background.
It also generates build files for a large set of build tools, like
Make and Visual Studio.
I can't imagine the GNU development community embracing CMake, for any
number of reasons -- licensing, 'not-invented-here', an existing,
functional build system, CLANG uses it ;-) -- but some of the things
that people find difficult about building and deploying the GNU
compilers are fairly easy with CMake. As the complexity of projects
like GCC grow, it's never the wrong time to try and refine and
simplify the way it's built and deployed.
