#38582: RFE: update the configure.ac file in base to silence some warnings produced by autoscan --------------------------+-------------------------------- Reporter: egall@… | Owner: macports-tickets@… Type: enhancement | Status: new Priority: Normal | Milestone: Component: base | Version: 2.1.3 Resolution: | Keywords: haspatch Port: | --------------------------+-------------------------------- Comment (by egall@…): I don't think any of these macros can actually fail, so I don't see why they'd need fallback code. They're just for adding more information about the user's system to their `config.log` and to their `config.h` (which I guess MacPorts doesn't use, but it could do so easily...). Also it looks like a lot of the macros currently in `configure.ac` were originally added with an older version of `autoscan`, this would be just updating those to a more recent version. Anyway I'm planning on editing a table into this post showing more about these macros: ||= Macro =||= contents of line `autoscan` is referring to when it says a file wants this macro =||= context (how the line is used) =||= human explanation for how adding the macro will be useful =|| ||= `AC_CHECK_FUNCS([dup2])` =||= =||= =||= =|| (coming back to this later...) -- Ticket URL: <https://trac.macports.org/ticket/38582#comment:6> MacPorts <http://www.macports.org/> Ports system for OS X
