Well, just don't use the clang plugins then?

Not specifically.
I'm still on Ubuntu 14.04 and didn't have the time to install a more 
recent version (apparently 3.8 should be available on my distro).


Thanks.

This specific issue should be fixed with 
 
"Use compat::isLookupContext."


However, most people (esp. those writing plugins) probably use newer 
Clang than 3.6 by now, so there may be more issues with older Clang 
remaining in compilerplugins/clang/ that remained undetected for a while.

Hello Giuseppe,

I downloaded 3.6.2 and 3.7 Clang version, it seems "isLookupContext" has
been added in DeclContext from 3.7

I think it should be taken into account here:
 38 inline bool isLookupContext(clang::DeclContext const & ctxt) {
 39 #if CLANG_VERSION >= 30700
 40 return ctxt.isLookupContext();
 41 #else
 42 return !ctxt.isFunctionOrMethod()
 43 && ctxt.getDeclKind() != clang::Decl::LinkageSpec;
 44 #endif
(see
http://opengrok.libreoffice.org/xref/core/compilerplugins/clang/compat.hxx#38)

Now I must recognize I don't know why CLANG_VERSION isn't detected as <
30700.

Just to be sure:
- you don't have 2 clang version in parallel
- you didn't downgrade your clang version
- you runned "ccache -C && make clean && ./autogen.sh && make" once to be
sure, there's no buggy remnants from old build
?
