Hit by this, too. build.log: code.l:3700:2: error: #error "You seem to be using a version of flex newer than 2.5.4 but older than 2.5.33. These versions do NOT work with doxygen! Please use version <=2.5.4 or >=2.5.33 or expect things to be parsed wrongly!" eix tells me that i have sys-devel/flex-2.6.0, so I don't really understand the error message ...(?)
Same issue here. Looks like the check thinks that 2.6.0 is older than 2.5.33, most likely because its comparing 0 from 2.6.0 against 33 from 2.5.33.
This is an error in doxygen's build system.
commit 01e26b007b888ff0b0931f41531319de2a8fbb8f Author: Matthias Maier <tamiko@gentoo.org> Date: Thu Dec 10 17:25:08 2015 -0600 app-doc/doxygen: fix version check for sys-devel/flex-2.6.0 Apply a patch to fix doxygen's build system to successfully detect flex-2.6.0 as sufficiently modern version. The build system accidentally only compared the minor version number... Upstream: https://github.com/doxygen/doxygen/pull/413 Gentoo-Bug: 567018 Package-Manager: portage-2.2.26
