Building the net-p2p/eiskaltdcpp package fails with various Qt4 moc -related errors that occur (apparently) because an incompatibility between newer versions of the Boost libraries and the Qt4 libraries (a Qt bug). This bug is fixed by Upstream for Qt5 but a fix will not be back-ported to Qt4... Reproducible: Always Steps to Reproduce: 1. Update to =dev-libs/boost-1.57.0 2. Attempt to build =net-p2p/eiskaltdcpp-9999 package with qt4 use flag enabled Actual Results: various Qt4 moc build errors are generated... usr/include/boost/type_traits/detail/has_binary_operator.hp:50: Parse error at "BOOST_JOIN" usr/include/boost/type_traits/detail/has_binary_operator.hp:50: Parse error at "BOOST_JOIN" eiskaltdcpp-qt/CMakeFiles/eiskaltdcpp-qt.dir/build.make:77: recipe for target 'eiskaltdcpp-qt/src/moc_UCModel.cxx' failed make[2]: *** [eiskaltdcpp-qt/src/moc_UCModel.cxx] Error 1 ...

Created attachment 408224 [details] eiskaltdcpp-9999.ebuild I've attached a (very!!) hacked together ebuild that wraps the boost functions included (in the Qt header files) with "no-moc" C pre-processor tags. A work-around suggested by Upstream (see the Qt bug URL).
Yes we're aware of this, we've had other bugs. Nothing we can do about it. Just wrap the problematic includes in "#ifndef Q_MOC_RUN ... #endif" as suggested in the upstream bug. For an example see https://cgit.gentoo.org/proj/kde.git/commit/?id=cc2a85965f6be1c55f1f43fbbc4a85420186f8e4 Or the workaround can be applied directly to the boost header(s) I guess.
"we" in the previous comment stands for "the gentoo qt team"

Sure - like I said I've got working ebuilds for the package already. I'm just being "responsible" and filing a bug against the package. Since it won't build for other folks - I can offer a "quicker solution" for this issue after all... I've re-written it a little - to use a standalone Moc patch script (OK it's a just an awk hack). The "fixed" ebuilds, for net-p2p/eiskaltdcpp, are now in my overlay (bobwya).
Created attachment 429590 [details, diff] eiskaltdcpp-2.2.9-boost157.patch I've guarded all boost includes. Please give it a try.
I've just emerged eiskaltdcpp 2.2.9 with Boost 1.58.0-r1 without any problems. Is this issue still actual?

Uhhmm... I'd forgotten I'd even opened this bug report - it was many months ago though :-) I'm using my own qt5 EAPI 6 build of this package now - with boost 1.60.0 ... Time moves on, etc. ...
Please reopen if issue persists.
