Description Fabio Scaccabarozzi 2016-07-07 16:49:50 UTC

Created attachment 439972 [details, diff]
Include sys/types.h and fix compile phase

As per title, the package fails to build with musl.
The reason being the package using (caddr_t), which is not pulled in from musl's headers (as it is with glibc's ones I would guess).
Dropping the attached patch in patches/ and making the ebuild apply it is enough to solve the issue.
Note that musl seems to provide this as a compatibility layer and declares caddr_t as "char *" (sys/types.h).

Please note that there is an open issue upstream, but the project seems dead:

    net-proxy/macchanger: add patch for compilation with musl

    The patch is used by Alpine Linux, and has been submitted upstream:

    https://github.com/alobbs/macchanger/issues/14

    Also, do a revbump, bump EAPI, and eprefixify.
