Hi All, I am trying to build the 'lld' linker on Mac OS 10.9, but during the build, I am getting the errors. Following are the steps that I have followed: 1.     I have downloaded the ‘llvm-stable’ source code from the following location:   https://github.com/llvm-mirror/llvm/tree/stable   2.     Machine details(on which llvm source code isbeing built) are as follows: $ sw_vers

+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

Hi, I switched from "configure and make" to "cmake" build-system and wanted to speedup my build. In my build-script I use... CMAKE_JOBS="1" ##CMAKE_JOBS=$(($(getconf _NPROCESSORS_ONLN)+1)) JOBS_CMAKE_OPTS="-DLLVM_PARALLEL_COMPILE_JOBS=$CMAKE_JOBS -DLLVM_PARALLEL_LINK_JOBS=$CMAKE_JOBS" [1] says in "LLVM-specific variables" section... ***

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?

Hallo all, I was trying to Build LLVM with the cmake option LLVM_ENABLE_MODULES just out of curiosity. I used the RELEASE_400/final tag. It didn't work as I almost expected. So I'm wondering if the modulemaps aren't maintained anymore? If they aren't maintained anymore, why aren't they removed and that cmake option also removed?

Hello, on the problems cross-building compiler-rt: Tried to follow https://llvm.org/docs/HowToCrossCompileBuiltinsOnArm.html which lead to this cmake: cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF

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 #

Hello Peter and Lists, thanks a lot, that way it worked out! The final cmake was cmake -G "Ninja" ../llvm/projects/compiler-rt/ -DCOMPILER_RT_BUILD_BUILTINS=ON -DCOMPILER_RT_BUILD_SANITIZERS=OFF -DCOMPILER_RT_BUILD_XRAY=OFF -DCOMPILER_RT_BUILD_LIBFUZZER=OFF -DCOMPILER_RT_BUILD_PROFILE=OFF -DCMAKE_C_COMPILER=/usr/local/myclang/bin/clang -DCMAKE_AR=/usr/local/myclang/bin/llvm-ar

Hi cschen, It seems that libunwind (the one included in libcxxabi) is mandatory at the moment. Use the second build command instead: $ CROSS_COMPILING=arm ENABLE_LIBUNWIND=1 ./scripts/compile-all.sh Logan On Tue, Oct 7, 2014 at 5:32 PM, gamma_chen <gamma_chen at yahoo.com.tw> wrote: > After do "sudo apt-get update", the following are pass. > > Install the

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 again Christian, I've posted https://reviews.llvm.org/D55709 to see if we can get the documentation on how to cross-compile compiler-rt improved. I'll be out of office until next year so I may be a bit slow to respond to any follow ups.
