in autogen.input, with CLANGBUILD = CLANGDIR (though IIRC Lubos used a
somewhat different setup that did involve setting CLANGBUILD != CLANGDIR).
Then if it had worked, I wanted to try this:
CFLAGS="-fsanitize=memory -fsanitize-memory-track-origins
-fno-omit-frame-pointer -g -O2' CXXFLAGS='-fsanitize=memory
-fsanitize-memory-track-origins -fno-omit-frame-pointer -g -O2' make
as I read here:
https://wiki.documentfoundation.org/Development/BuildingOnLinux#Compiler_flags
I once toyed around a little with -fsanitize=undefined, but it took some
tweaking of solenv/gbuild/ to get the relevant flags properly into the
build IIRC. (I have those changes still lying around locally, but never
came around to look into it again and clean up. Also,
-fsanitize=undefined started to fail rather quickly due to problems
discussed in the thread starting at
"ubsan: check type_info equality via strcmp," which would need fixing in
our cppumaker-generated headers.)

That's odd (and unrelated to Clang); a plain "make" should create the
executable instdir/unxlngx6/program/soffice.bin. (But the switch to
instdir is relatively new, maybe you are working off an incremental
build that somehow got confused?)

Re: About Clang headers on Debian
Building with clang succeeded, it's the first time that I can build LO with
clang! :-)
Thank you!

Using the Clang plugin is very much optional. Don't worry. (But sure, if you can figure out what package to install to get the Clang API, then you will be able to build our Clang plugin and you will get warnings about your code in some more cases if you (or somebody else) introduces dubious things. --tml ___ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
About Clang headers on Debian
Hello, On pc Debian x86-64 testing updated today, I tried to build with clang. But I got this warning after autogen.sh Cannot find Clang headers to build compiler plugins, plugins disabled Checking in configure.ac, I found this: 5625 CPPFLAGS="$CPPFLAGS -I$CLANGDIR/include -I$CLANGDIR/tools/clang/include -I$CLANGBUILD/include -I$CLANGBUILD/tools/clang/include -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS" 5626 AC_CHECK_HEADER(clang/AST/RecursiveASTVisitor.h, 5627 [COMPILER_PLUGINS=TRUE], 5628 [ 5629 if test "$compiler_plugins" = "yes"; then 5630 AC_MSG_ERROR([Cannot find Clang headers to build compiler plugins.]) So I checked which package provided "RecursiveASTVisitor.h" root@julienPC:/home/julien# apt-file search RecursiveASTVisitor.h libclang-3.4-dev: /usr/lib/llvm-3.4/include/clang/AST/RecursiveASTVisitor.h libclang-dev: /usr/lib/llvm-3.2/include/clang/AST/RecursiveASTVisitor.h But this package is already installed: root@julienPC:/home/julien# apt-get install libclang-dev Reading package lists... Done Building dependency tree Reading state information... Done libclang-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. Should I create a symlink or should I override CLANGBUILD or CLANGBUILD so autogen.sh can find: /usr/lib/llvm-3.2/include/clang/AST/RecursiveASTVisitor.h ? Is/are Debian package(s) for clang/llvm buggy?
