Using gcc-6* to compile sys-block/thin-provisioning-tools-0.5.3 fails with:


error: cannot convert 'persistent_data::btree<1u, thin_provisioning::device_tree_detail::device_details_traits>::maybe_value {aka boost::optional<thin_provisioning::device_tree_d

Created attachment 433886 [details, diff]
thin-provisioning-tools-0.5.3-gcc6.patch

A patch to compile thin-provisioning-tools-0.5.3 with gcc-6*.  boost::optional doesn't seem to implicitly cast to bool so this patch just applies some explicitly casts.

please test/check thin-provisioning-tools-0.6.1 as that's the latest in the tree.  if that still fails, upstream is github, so it should be trivial for you to fork & get your patch merged there (i got a few PRs accepted in the last few days).

Hmmm.  Looks like it was already resolved in git, seemingly for a separate issue, by forcing g++-98 dialect:

Hello there!

This bug affects me also
Mein output of 'emerge --info'
https://paste.pound-python.org/show/A4dXW34qq4nxwGIg1Bcj

Also I have installed GCC 6.2.0 and sys-block/thin-provisioning-tools-0.6.1
Nothing fixed. Please as was 6.2.0 released, prepare patch.
Thank You!

Or put thin-provisioning-tools-0.6.2 or thin-provisioning-tools-0.6.3 in the portage tree since this was fixed in 0.6.2-rc3.

thanks.  this one is older, but that one is fixed, so easier to dupe that way.
