similar to: error in building llvm with default options

Various options for reducing memory usage when building LLVM: * Don't use bfd-ld, at least use gold, probably use lld if you have it available * With Ninja and/or CMake there's some way to specify the maximum number of concurrent linkactions - lower this to fit in your available memory * If you're building with debug info: Use Split DWARF On Thu, Jan 2, 2020 at 5:21 AM Kókai Péter

The last time this came up, we agreed something should be done to fix the defaults, but nobody picked it up and ran with it. I think there was consensus, it just needs legwork now.

Dear llvm developpers, I followed the tutorial to build llvm and clang provided here: https://clang.llvm.org/get_started.html The sources are in sync with subversion repository, and I ended up with more than 30GB of binaries in llvm/bin as shown at the end of this message. I assume I did something wrong, but I did not find any entry in the doc that helps me understand how to reduce the size of

Hello, Maybe this is not a bugs. But i fail to install llvm many times and different machine(debian os). First, i follow the instruction: http://cilium.readthedocs.io/en/latest/bpf/#llvm But during in compiling, i alway get: ... /home/yubo/git/llvm/tools/clang/lib/Basic/VirtualFileSystem.cpp: In member function ‘virtual llvm::ErrorOr<std::unique_ptr<clang::vfs::File> >

Hi, I tried to build LLVM 4.0.1 on a Slackware Linux box with 3 GB of RAM using gcc-7.1.0. Near the end of the build process, I hit the following error: [ 89%] Linking CXX shared library ../../lib/libLTO.so collect2: fatal error: ld terminated with signal 9 [Killed] compilation terminated. tools/lto/CMakeFiles/LTO.dir/build.make:269: recipe for target 'lib/libLTO.so.4.0.1' failed

Hi. I'm using llvm DataFlowSanitizer. I add such code in library libtiff. dfsan_label lt_label = dfsan_create_label("buf_offset", 0); dfsan_set_label(lt_label, (unsigned char *)buf, size); But when i compile libtiff with "-fsanitize=dataflow" option, then there is an error as follows: ../libtiff/libtiff.so.5.2.5: undefined reference to `dfs$jbg_enc_init'

Hello everybody, I am very new to llvm and I am struggling to install it on my 15.10 Xubuntu with kernel 4.2.0-34-generic #39-Ubuntu SMP x86_64 GNU/Linux. I essentially intend to use the clang static analyzer, but it seems that I have to build it on top of llvm and clang. Unfortunately I run into the following problem. CXX shared library ../../../lib/libc++.so at around 52% of the procedure

Hi I am trying to install llvm and clang on ubuntu 16.04, I tried installing them using apt command but while running the pass it gives me error "error: llvm/pass.h not found *#include"llvm/pass.h"* so i tried installing using the source code and building it my self, *make *fails at 98% with this error *collect2: error: ld returned 1 exit

As the question asks, I'm having some trouble using initializeAllTargets(). I have a CMakeLists that uses: llvm_map_components_to_libnames(LLVM_LIBS ... AllTargetsAsmParsers AllTargetsAsmPrinters AllTargetsDescs AllTargetsInfos ...) However, even with these, when I try to compile my program, I get linker errors: CMakeFiles/sxhc.dir/src/main.cpp.o: In function

Hi Dimitry, I do not particularly need to build libc++ from the package. Is the name of the package's libc++, libcxx, because this is where the installation starts finding undefined references, during linking CXX shared library ../../../lib/libc++.so. Please check below the first part of the log when the first error appear, I omited repeating results. Furthermore, the undefined references are

I tried deleting my build directory and restarting from scratch $ cd llvm-project $ mkdir build && cd build $ cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS=lld ../llvm $ make I got this error: make[2]: *** No rule to make target 'llvm/cmake/modules/GenerateVersionFromVCS.cmake', needed by 'tools/lld/Common/VCSVersion.inc'.

The problem is that test-suite is now building as part of the Phase[123] builds (because this project contains CMakeLists.txt's now) but cmake 3.0.2

Hi, I try to build lldb with Cmake (gcc-5.3.0 is necessary for CUDA) on my "SUSE Linux Enterprise Server 12.2 (x86_64)". Unfortunately the build process breaks for lldb with the below mentioned error message. I've downloaded the following packages and configured with the following commands. svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm cd llvm/tools svn co

Hi Ioannis, If you only want the clang static analyzer, there is no need to check out and build libc++ as part of the process. The rest of the build can just use the system C++ library, which will be libstdc++ on Xubuntu. That said, without the full build log, it is hard to say what went wrong. Specifically, which references were undefined? -Dimitry > On 26 Mar 2016, at 16:04, Ioannis

Let in a program a variable 'x' is tainted. There is an assignment 'y=x' where y is untainted. How to check the taintflow in the output or data flow graph ? Any suggestions? Thank you.

The trigger for this build failure is the usage of -DLLVM_BUILD_EXTERNAL_COMPILER_RT:BOOL=ON. If I drop that
