I'm trying to build clang from svn trunk to give a try to MemorySanitizer.
So I followed, http://clang.llvm.org/get_started.html
but I don't know what to put in my autogen.input
Either I get this:
* WARNING : Cannot find Clang headers to build compiler plugins, plugins
disabled
or I get this:
make: *** No rule to make target `/home/julien/llvm-svn/build/bin/clang',
needed by
`/home/julien/compile-libreoffice/libo_clang/compilerplugins/obj/clang-timestamp'.
Stop
Here's the end of my autogen.input when I get last message:
CLANGBUILD=/home/julien/llvm-svn/build
CLANGDIR=/home/julien/llvm-svn/llvm
CC=/home/julien/llvm-svn/build/Debug+Asserts/bin/clang
CXX=/home/julien/llvm-svn/build/Debug+Asserts/bin/clang++
The script with which I build Clang trunk is
#!/bin/bash
set -ex
mkdir "${HOME?}"/clang/trunk
svn co http://llvm.org/svn/llvm-project/llvm/trunk "${HOME?}"/clang/trunk/src
svn co http://llvm.org/svn/llvm-project/cfe/trunk \
"${HOME?}"/clang/trunk/src/tools/clang
svn co http://llvm.org/svn/llvm-project/clang-tools-extra/trunk \
"${HOME?}"/clang/trunk/src/tools/clang/tools/extra
svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk \
"${HOME?}"/clang/trunk/src/projects/compiler-rt
mkdir "${HOME?}"/clang/trunk/build
cd "${HOME?}"/clang/trunk/build
"${HOME?}"/clang/trunk/src/configure --prefix="${HOME?}"/clang/trunk/inst \
--enable-optimized CC=gcc CXX=g++
make -j12
make install -j12
and then have
CC=/home/sbergman/clang/trunk/inst/bin/clang
CXX=/home/sbergman/clang/trunk/inst/bin/clang++
CLANGBUILD=/home/sbergman/clang/trunk/inst
CLANGDIR=/home/sbergman/clang/trunk/inst
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
<http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20130812/086127.html>
"ubsan: check type_info equality via strcmp," which would need fixing in
our cppumaker-generated headers.)
