Bug #14827
closed
Fails to compile on GNU/Hurd: IOV_MAX undefined
Description
Description
The existence of the writev() syscall does not imply that the IOV_MAX macro exists.
Because on GNU/Hurd operating systems the IOV_MAX macro does not exist, Ruby fails to compile there.
Reproduce
Install a GNU/Hurd operating system and try to compile Ruby.
The patch
The patch simply ignores IOV_MAX if it is not defined.

Thanks for the report.
I'm trying to reduce mixing CPP and C conditionals, so I hoisted
the IOV_MAX check into a new iovcnt_ok function in r63576 which
should still work for you.
