Bug 593922 – sys-block/thin-provisioning-tools-0.6.1 build failure with gcc-6.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description vltg0903 2016-09-16 06:39:36 UTC]

The build breaks off with an error complaining that a boost::optional value can't be implicitly converted to a bool, for which boost::optional presumably has an operator defined. Applying the appended patch fixes this problem by calling the method 'is_initialized()' rather than using the implicit conversion.

Reproducible: Always

This patch didn't work for me. I'm using boost 1.62 and gcc 6.20

It turns out that your patch wasn't liked very much by euser_patch, so I had to remake it. I also added some things to it and will be uploading that to the new version bug request. The new patch takes care of a lot. :)

Thanks for pointing me in the right direction.

upstream 0.6.3 seems fine with gcc-6.2, so, probably it just a matter of version bump.

[Comment 7 Robin Johnson 2017-01-30 00:11:12 UTC]

0.6.3 is already in the tree.
