Not a gcc issue. mythtv/libs/libmythmetadata/imagemetadata.cpp has this: // libexiv2 for Exif metadata //#include <exiv2/exiv2.hpp> // Note: Older versions of Exiv2 don't have the exiv2.hpp include // file. Using image.hpp instead seems to work. #ifdef _MSC_VER #include <exiv2/src/image.hpp> #else #include <exiv2/image.hpp> #endif Contrary to that comment, image.hpp does not work, and exiv2/exiv2.hpp should be used instead.
Yeah, I'm not sure how far back one has to go for that comment to be true. It seems that exiv2/exiv2.hpp was included 9 years ago first. https://github.com/Exiv2/exiv2/blame/19e0693920b687ee789c37c4068e829e083d3838/include/exiv2/exiv2.hpp
And can you confirm that uncommenting this header makes mythtv then build?
Created attachment 586784 [details, diff] mythtv-exiv2-fix I can confirm that the proposal resolves build errors. I'm including the patch here; it can be added into a revbump commit for media-tv/mythtv. $ grep -n PATCH media-tv/mythtv/mythtv-29.1-r2.ebuild 140:PATCHES="${FILESDIR}/${PN}-exiv2-fix" I would need to clone the gentoo git tree in order to open a pull request. If that's necessary, I'll do so. However, if someone else is able to apply the patch into the tree, it's preferable.
