I'm completely stuck with rebuilding xfsdump in slackware-current by the following message (gcc-7.1.0 I suppose?):

Can someone help with this message?

Maybe xfsdump-3.1.6 needs an older version of xfsprogs, like 4.8.0 for example.

The upstream repo is at https://git.kernel.org/pub/scm/fs/xfs/xfsdump-dev.git. Looking at the commits, they messed around with the includes a lot since 3.1.5, so maybe 3.1.5 will work (with an older version of xfsprogs to go with it).

Or maybe this is something completely new relating to gcc-7.1. Try building xfsprogs-4.10 and xfsdump-3.1.6 with gcc6 or gcc5.

thanks for your advice, it works with xfsprogs-4.8.0 and gcc-7.1.0.
