| Description |
|
When building with zfs, ./configure lets us define specific paths for spl and zfs headers, in addition to spl and zfs object directories: The problem is there is no equivalent for zfs development headers. In config/lustre-build-zfs.m4, the 'LB_ZFS_USER' configure check looks at /usr/include/libzfs and /usr/include/libspl, and there is no way to specify alternate directories. It seems a configure option like --with-zfs-devel is missing. |

Nathaniel Could you please comment on this one? Thanks Peter |

Brian may be able to comment as well, since he added those configure checks (added him to watchers). |

yes, same problem here.. it'd be very nice if we don't need to install spl/zfs on a build system (os/x in my case). |

Right, a --with-zfs-user option for the user space libraries was accidentally omitted. I'm all for adding one, and updating the default behavior such that it automatically disables the zfs user builds if the libraries don't exist AND --with-zfs wasn't passed. For now you should be able to pass the --without-zfs option to disable the checks. |

Brian, would it be possible to build with in-tree headers? |

Adding an option to specify the libzfs and libspl include path should allow you to build using the in-tree zfs headers. Then you would then also need to add lib/libzfs and lib/libspl directories to your library path so dlopen(3) can find them at run time. Wouldn't it be easier just to install the devel headers and libraries? Unless your actively working on the ZFS tree I'm not sure building in-tree is worth the hassle. |

well, I do all the builds on the host (OS/X) and then run in a virtual machine. |
