Hello there, I'm building a Linux distribution based on musl and LLVM as default toolchain (including lld/libc++/libc++abi/libunwind rather than GNU). For most of the time this works pretty well. However I'm having troubles with few packages, webkit for instance fails because of max_align_t being redeclared in musl's stddef.h I see that stddef.h is provided by both musl and in the

Here is tests/reg-tests-1c.Rout.fail - http://pastebin.com/raw/3QVDUBwT About the libm, I don't know which one R uses. musl has its on libm. http://git.musl-libc.org/cgit/musl/tree/src/math I think I also have openlibm installed, but I don't think that's used. Any more information I can give to help debug this? Thanks. On Mon, Feb 1, 2016 at 3:49 PM, Martin Maechler <maechler

I want to build LLVM-based toolchain with Musl, I have LLVM sources with clang and lld (under `tools` directory) and libunwind, compiler-rt, libcxx and libcxxabi (under `projects` directory). All are the latest versions cloned from GitHub mirror, branch `master`. I'm trying to configure with the following options: CLANG_DEFAULT_CXX_STDLIB = libc++ CLANG_DEFAULT_RTLIB = compiler-rt

Alpine linux is a distribution that uses musl libc instead glibc. Here are my steps to reproduce: On Alpine linux, download LLVM, Clang, LLD 6.0.0 from releases.llvm.org, and build them from source. $ clang -c hello_world.c $ ld.lld --gc-sections -m elf_x86_64 -o hello_world /usr/lib/gcc/x86_64-alpine-linux-musl/6.4.0/../../../../lib/Scrt1.o

There is incompatibility between R strptime and musl libc. I posted about it on their mailing list, but they need more information I can't provide, so I'm forwarding the message here in hope R developers can help.

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 have managed to compile llvm and clang against musl, but it behaves really strange: At first I tried to launch the compiler with musl dynamic loader: $ LD_LIBRARY_PATH=/path/to/musl/lib /path/to/musl/lib/ld-musl-x86_64.so.1 /path/to/llvm/bin/clang -v clang version 4.0.0 (https://github.com/llvm-mirror/clang 40adebeca0f99006d407508653c2cbd270a1a51c) (https://github.com/llvm-mirror/llvm

Can you add `--reproduce=repro` to lld command line? That generates repro.tar in your current directory which contains all input files. And then please compress and upload it somewhere so that we can take a look.
