Hi All, I am first time trying build CLANG+LLVM using cmake+ninja build system. I updated all my CLANG+LLVM sources to current trunk, and I successfully built it using classic *make* build system. But, trying to build the same with cmake+ninja build system resulting in following build failures for compiler-rt sources. Am I missing something basics here? ==================== cmake command used:

Hello, It looks like compiler-rt CMake scripts don't take CMAKE_CXX_FLAGS into account. This is because clang_compile and clang_link_shared functions call the newly-built compiler directly, and they don't add those flags. Using CMAKE_CXX_FLAGS is necessary on systems where the C++11-enabled libstdc++ is installed not in the default location. For example, the CentOS buildbot uses:

I'm seeing this too. CC'ing the author ubsan stuff. Richard, I know you were OK with only supporting Clang-bootstraps, but I don't think that's terribly viable here. We should be able to build ubsan's runtime with standards conforming code unless there is some fairly extreme reason not to...

I use latest cmake+ninja which are built from latest sources. ================================= > cmake --version cmake version 2.8.9.20121011-g2876 ================================= -- mahesha On Fri, Oct 12, 2012 at 7:35 PM, Mahesha HS <mahesha.llvm at gmail.com> wrote: > Hi All, > > I am first time trying build CLANG+LLVM using cmake+ninja build > system.

+Bob Wilson I don't know if this is a recent Apple regression, or if it's now catching something which had always been invalid. -bw On Mon, Nov 11, 2013 at 8:44 AM, Jack Howarth <howarth at bromo.med.uc.edu>wrote: > On Mon, Nov 11, 2013 at 11:03:47AM -0500, Jack Howarth wrote: > > On Mon, Nov 11, 2013 at 06:46:47PM +0400, Alexander Potapenko wrote: > > > This

I'd sort of hope to treat optional sanitizer runtimes

llvm/cmake/modules/HandleLLVMStdlib.cmake specifies "-stdlib=libc++" for CMAKE_CXX_FLAGS when LLVM_ENABLE_LIBCXX and CXX_SUPPORTS_STDLIB. From what I can see this is a flag intended for the linker and not the compiler. I'd like to submit a change to delete CMAKE_CXX_FLAGS from this append() but I wanted to check in with the list to see if that makes sense or if there are other

This file is for configure+make build, not CMake, so I'm not sure why it's being included into your build (these failures aren't reproducible for me). Can you please list the exact steps you're doing to build LLVM with CMake and make sure you don't have additional CFLAGS (LDFLAGS etc) defined?

​Hi again, Teresa. Looks like I had forgotten to report back with success when finally building 3.9.0 in ThinLTO linker mode back in October. Sorry about that and thanks for helping me out. I know how important it is to get success reports as well, as a developer myself, so sorry again :(. While that worked back then, last weekend I tried to build 3.9.1 using 3.9.0 as installed from Arch Linux

I had only a quick view on the blog-texts. It might be that a CLANG generated with LTO/PGO speeds up the build. Can you confirm this? Can you confirm binutils-gold speed up the build? Has LLVM an own linker? Can be used? Speedup the build? Yesterday night I loooked through available CMAKE/LLVM variables... ### GOLD # CMAKE_LINKER:FILEPATH=/usr/bin/ld #

Hi Dean, Wondering if you've seen anything like this: /usr/local/google/home/blaikie/dev/llvm/build/clang/debug/split/notypes/nostandalone/projects/compiler-rt/lib/xray/tests/unit && /usr/local/google/home/blaikie/dev/llvm/build/clang/debug/split/notypes/nostandalone/./bin/clang fdr_logging_test.cc.x86_64.o xray_unit_test_main.cc.x86_64.o gtest-all.cc.x86_64.o -o

I'm unsure why this is failing this week, but when I build for FreeBSD HEAD, I now get a failure to find <stdarg.h>. Very strange. Maybe its missing a -I /usr/include somewhere?
