similar to: Building LLVM and Clang using Clang?

Hi Folks, I am building LLVM 3.9.1 using the Yocto build system for a cross build. The compiled bins/libs work totally fine on the target machine however there seems to be an intermittent race condition during the build which causes a build failure. On the failed builds I usually see things being linking/compiling twice e.g. Linking CXX static library ../libLLVMSupport.a cd

Hi, Recently my libcxx enabled llvm/clang builds has started to fail in stage2. I must admit I am stomped because I cannot make sense of the error: [ 723s] FAILED: /home/abuild/rpmbuild/BUILD/llvm/stage1/bin/clang++ -DLLVMSupport_EXPORTS -DNDEBUG -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -stdlib=libc++ -fPIC -fvisibility-inlines-hidden -Wall -W

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?

Ok looks like r207606 regressed this. CC'ing Niko. Niko, please see the messages below. This is on openSUSE 13.1 both on i586 and x86-64. Reverting r207606 fixes the second stage bootstrap.

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

Hi, On the OpenMandriva side, x86_64 passes all checks. We're having some problems with other architectures though (see below): x86_64 succeeded, packages are here: https://abf.openmandriva.org/build_lists/76792 i586 fails to build, but this seems to be an issue with 3.8.1 (which we're using to build 3.9): /usr/bin/clang++ -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS

I'm trying to compile LLVM with musl libc library. The compilation process fails on the following: x86_64-linux-musl-g++ -DGTEST_HAS_RTTI=0 -DLLVM_BUILD_GLOBAL_ISEL -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -Ilib/Support -I../lib/Support -Iinclude -I../include -fPIC -fvisibility-inlines-hidden -Werror=date-time -std=c++11 -Wall -W -Wno-unused-parameter

I am updating our out-of-tree copy of LLVM to track the head (revision #272991 specifically). I have it building successfully with VC++ 2013 and CMake v3.5.2 on Windows, and with GCC v4.8.5 and CMake v3.5.2 on CentOS; but when I try building on Windows using Cygwin32 I get the following build failures: [ 4%] Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/Signals.cpp.o In file

I noticed a problem with llvm-config.exe on Windows: >"c:\Users\andy\llvm+clang-6.0.0rc2-win64-msvc-release\bin\llvm-config.exe" --system-libs psapi.lib shell32.lib ole32.lib uuid.lib But then when I link against LLVM and these libs, I get: lld: error: LLVMSupport.lib(Process.obj): undefined symbol: __imp_CryptAcquireContextW lld: error: LLVMSupport.lib(RandomNumberGenerator.obj):

*System:* Debian Linux Sid/Unstable amd64 *LLVM/Clang:* Trunk *Scenario:* In the past couple of days I've been compiling against trunk I get two separate and spurious hang ups with CMake. *Note:* I build against more than just X86 follow along the progress of other platforms, though just building for X86 produces the same results below. *Assumption:* Configure cmake with prior built

Hello LLVM developers, Following some hints on this mailing list earlier this year on how to make clang faster than stock llvm.org builds I have implemented a script that builds a PGO optimized version of clang by following the guide here: http://llvm.org/docs/HowToBuildWithPGO.html This works great on macOS and Linux - we gained almost 15% in our project with this technique. I am now looking at

Thanks Dimitry. That worked. I see some warnings in my compilations: > Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/IntEqClasses.cpp.o > [ 2%] clang-3: warning: argument unused during compilation: '-nostdinc++' > Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/IntrusiveRefCntPtr.cpp.o > clang-3: warning: argument unused during compilation:

Hi, I'm trying to build llvm (git monorepo) on Ubuntu 18.04 with EXPENSIVE_CHECKS enabled and running into various errors compiling SourceMgr.cpp, depending on which host compiler I use. For example with GCC: $ CC=gcc-8 CXX=g++-8 cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON ~/git/llvm-project/llvm/ && ninja ... [89/2690] Building CXX object

Googling indicates that cygwin doesn't have that functionality. Or, at least, didn't in 2010, when someone asked about the same problem: https://cygwin.com/ml/cygwin/2010-01/msg00596.html "cygwin has only dlsym() not the SGI DL_info + dladdr() yet. clang just needs it to get the path for the CIndex dll. This should be possible with the code in the LLVM_ON_WIN32 section, and convert

Dear testers, 3.9.0-rc1 was just tagged from the 3.9 branch at r277207. This took a little longer than I'd hoped, but I think the branch is in a decent state now. There are still open merge requests and bugs, but I'd like to get the real testing started to see where we're at. Please build, test, and upload binaries to the sftp. Let me know how it goes. I'll upload source, docs,

Hmm. What about the errors I quoted from using clang-7 (starting about a third of the way down my email, sorry if they got kinda lost in all the noise)? Thanks, Jay.

I just ran into this today. Do we need to update our requirements on libstdc++ version? Jay, did you figure out a way around this?

Hello everyone, I'm trying to compile LLVM and Clang into LLVM IR with debug info. I know that clang++ -g2 -S -emit-llvm <filename> does this, but I'm unfamiliar with CMake. I tried changing CMAKE_CXX_FLAGS in CMakeCache.txt to "clang++ -g2 -S -emit-llvm," "-g2 -S -emit-llvm," and "-emit-llvm," but everything I tried resulted in a failed build, and/or
