* Prevent += called on temporary O[U]String instancesStephan Bergmann2015-11-091-0/+1
| | | | | | | | | | | | ...found regression e31205f3ec1f941ab5a188bfde6329edf2acc55b "EditUndoRemoveChars::GetStr must return a reference" and dubious code 0e23f7b0839df68d277186b4df54ba391ac3406a "Lets assume this doesn't want to update m_pForcedPrefix->GetText() anyway" in addition to the apparent sillies directly fixed in this commit.

* Avoid unhelpful -Wunused-variableStephan Bergmann2015-09-301-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | ...at least from "g++ (GCC) 5.1.1 20150618 (Red Hat 5.1.1-4)" with --disable-debug, when a namespace-scope const variable with a "complex" initializer declared in an include file remains unused. Avoid that warning via SAL_CONSTEXPR, which in turn requires large parts of o3tl::is_typed_flags to be SAL_CONSTEXPR, which in turn requires a new HAVE_CXX14_CONSTEXPR to allow assert in constexpr functions, which in turn requires using -std=c++14 instead of -std=c++11 where available, which in turn (a) requires to /not/ use -std=c++14 if it would run into a bug between Clang and libstdc++ discussed at <https://llvm.org/bugs/show_bug.cgi?id=24115> "llvm-nm fails to build with gcc 5.1's libstdc++" (and which hits us in sfx2/source/control/thumbnailview.cxx), and (b) requires a new HAVE_CXX14_SIZED_DEALLOCATION to work around GCC 5.1 -Werror=sized-deallocation (where Clang >= 3.7 only supports C++14 sized deallocation when explictly enabled via -fsized-deallocation, btw). This effectively reverts ff6462e6307e6924dc6c8178043ae9032f4b4152 "avoid unused variable warning:" again.

* Fix check for broken standard libraryStephan Bergmann2015-06-191-0/+1
| | | | | | | | The compiler's __GNUC__ etc. need not match the libstdc++ version used (esp. when using Clang as compiler), and libstdc++'s __GLIBCXX__ macro doesn't inrease monotonically with version numbers, so resort to a configure check. Change-Id: I06de6b68324169863f6f5c31ae5d855e8b04cd6b

* Check for the C++11 "final" specifier and introduce SAL_FINALTor Lillqvist2013-04-081-0/+1
| | | | | | | | | | | | I think it is useful to use SAL_FINAL mainly as a documentation aid, to make it clear to a code reader when a class is not expected to be derived from, and when a virtual function is not expected to be overridden in a derived class. Possibly there is also some class of bugs that using SAL_FINAL will help find? Change-Id: I45002f020dcb52e8a9f2962ff98780f2b80627af

| | | | | | | | | | | | | ...replacing hard-coded GCC version checks. Those checks that guard #pragma GCC diagnostic ignored "-Wnon-virtual-dtor" appear relevant only for GCC itself, not Clang (which used to fail the old guards because it typically announces itself with a rather low __GNUC__/__GNUC_MINOR__ version), see 6e67c03dc0225fc66343546b14e902b9d238b1a3 "Enable -Wnon-virtual-dtor for GCC 4.6" Change-Id: I6bfa4d5caa6192e7a203ce829682bf6bb8d61a1b

* rhbz#908674: Adapt rtl::Allocator::construct to C++11Stephan Bergmann2013-02-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | ...otherwise, at least with some --with-system-boost versions and C++11 compilers, like with Fedora's boost-1.50.0-4.fc18.x86_64 and gcc-c++-4.7.2-8.fc18.x86_64, using this to copy-construct an instance of boost::unordered::detail::ptr_node<std::pair<rtl::OUString,Bootstrap_Impl*>> in the call to p_bootstrap_map->insert(...) in rtl_bootstrap_args_open (sal/rtl/source/bootstrap.cxx) would memcopy the ptr_node and fail to call rtl_uString_acquire, leading to memory corruption later on when rtl_uString_release is called one time too often. It is not entirely clear to me whether this is a shortcoming of the given Boost version, but this patch solves the problem and brings rtl::Allocator::construct in line with the (changed) Allocator requirements of C++11 anyway. The problem potentially lurks with every use of rtl::Allocator, but only showed now begining with LO 4.0 where e5111574fd904b38a3980ca4ea3d21cfcb22dea6 "Revert 'sb140: sb140: #i116981# clean up memory upon exit'" re-introduced code into rtl_bootstrap_args_open that inserts into a boost::unordered_map that uses rtl::Allocator.

* Use separate config_*.h files for BUILD and HOST when cross-compilingTor Lillqvist2013-01-311-0/+22
We have only been lucky so far that there hasn't been any compilation errors caused by using the HOST platform config_*.h files also for the BUILD platform. But as more and more information found out during configury is stored in config_*.h files, sooner or later it will be a problem. Move config/* to config_host/*. When not cross-compiling, the config_*.h files in config_host expanded from config_*.h.in are all there is. When cross-compiling, the generated config_*.h files for the BUILD platform are put into a config_build folder. Then use config_build when building the cross_toolset and config_host otherwise.
