clamav @0.102.4 does not build on older systems because of undefined symbols: "_unlinkat", "_renameat", "_openat"

Besides this, clamav does not compile with Apple's GCC on PPC Tiger but needs GCC7 or such.

Main.log from PPC Tiger

[ballapete (Peter "Pete" Dyballa)]

It builds when PortGroup legacysupport 1.0 is added to Portfile.

[kencu (Ken)]

thanks for sorting all that out.

[ballapete (Peter "Pete" Dyballa)]

The same happens on PPC Leopard, Mac OS X 10.5.8. I'll try the legacy support…

Main.log from PPC Leopard

[ballapete (Peter "Pete" Dyballa)]

The addition of PortGroup legacysupport 1.0 to Portfile allowed the recent version of clamav to build.

[danielluke (Daniel J. Luke)]

portgroup added - ​https://github.com/macports/macports-ports/commit/6bb0cd677a778b8c6f283d92e83df21c135795df
