autoconf: Depends on m4 about legacy-linuxbrew HOT 12 CLOSED

You need m4 installed.

Thanks!!! Now it works.

@MikeMcQuaid Should autoconf depend_on m4?

@sjackman Really there should be a either requirement or code in Linuxbrew to check the existence of this stuff.

For packages that are provided by the base Mac OS X install, I had the idea adding, for example, the depends_on 'm4' to autoconf, and keeping a list of which packages are provided on OS X (such as m4) so as to mark those dependencies as satisfied. Thoughts?

I think this should be done in reverse; add a requirement or other code somewhere in Linuxbrew (and Winbrew) which contains dependencies that don't come with those systems to match them with what comes with OSX. OSX will always be the primary platform so it doesn't make sense to add such things to the primarily OSX autoconf.

The packages need to know their own dependencies (that autoconf depends on m4 for example). It makes more sense I think to have that information in the individual formula and so, I think, in the base Homebrew. Whether that dependency is satisfied by the OS is the next question. We can hardcode that list for OS X. For Linux it will vary depending on the Linux distribution and which packages are installed, and so will likely have to be a dynamic test.

I think the better solution for Linuxbrew would simply be to specify the dependencies in the formulae downstream, like I do in Tigerbrew when necessary. I add a depends_on 'homebrew/dupes/m4' if MacOS.version < :leopard in autoconf, for example.

I just tried to install ruby-build and the m4 dependency is still missing. Any plan to specify these system dependencies as @sjackman or @mistydemeo were proposing?

Fixed. Thanks, Alejandro.

Thanks for the quick fix! Linuxbrew is getting really stable. 😃

Thanks! It has come a long way.
