Thanks Shoaib for a great summary. To summarize this as an answer to Louis' questions: 1. What is a "Standalone build"? What does it enable that a normal monorepo build can't? This means building any of the runtimes separately, where the runtime's CMakeLists.txt (e.g. path/to/my/llvm-project/libcxx/CMakeLists.txt) is the top-level one. The reason for using this variant is

[Cross-post to llvm-dev to make sure everybody relevant sees this] Hi, I'm currently trying to simplify the libc++/libc++abi/libunwind build systems and testing setup. In doing so, I am encountering issues related to "unusual" ways of building them. By unusual, I just mean "not the usual monorepo build with LLVM_ENABLE_PROJECTS". I would like to pin down what the set of

Hi, I'm working on cross-compiling llvm and sub-projects to dynamically build Clang toolchain and associated libraries for an embedded project. I'm starting with this mailing list, as I see the pattern using "config-ix.cmake" a common one; it's found in all the sub-projects. For those that are not aware, in CMake the standard approach for dealing with unique toolchains,

Folks, I'm running the libc++ tests in tree [1] and I'm seeing two class of errors: 1. -lrt is used, but there is no such "librt.a" in the path. Results are that some symbols are not found, or that the DSO object wasn't. Adding a symlink in build/lib/librt.a to build/clang/3.8.0/lib/linux/libclang_rt.builtins-aarch64.a worked. 2. "collate_byname failed to construct

Thanks a lot, but tried it and I get this: CMake Error at projects/libcxx/CMakeLists.txt:361 (message): LIBCXX_ENABLE_STATIC_ABI_LIBRARY is not supported on OS X Why is it not supported? If I manually embed libc++abi.a inside libc++.a it seems to work. Thanks! ardi On Mon, Oct 1, 2018 at 4:20 AM Petr Hosek <phosek at chromium.org> wrote: > > You can use

Isn't libc++.so dependent on libc++abi.so?

libc++.so should be a linker script that automatically pulls in libc++abi (see "Failed to read file header" in your output). And IIRC libc++abi is only one possible implementation that may be used by libc++, but I'm no expert here...

It was just brought to my attention that the RPATH configuration isn't uniform among the libraries produced by the release. Some use $ORIGIN../lib/ and others have none. Is this by design? It seems like it might be ideal for all of them to be configured the same way. If that makes sense I'll create a corresponding feature request. $ for f in

From what I can see all of the libraries without RPATH are runtime libraries that are used by binaries compiled with Clang. I think they don't have a dependency on other libraries in that directory, so what would be the advantage of having RPATH set on them?

Hello, I'm trying to create a pure LLVM toolchain (that will not depend on GNU and produce GNU-free code too) on a musl based distribution. For now, I use gcc to bootstrap and build all LLVM components. I do it individually because I was running out of space and memory trying to build all using LLVM_ENABLE_PROJECTS. Also, I don't want to create a all-in-one package. Then, once

If we are going to create a top level CMake file, we should just go ahead and eliminate all the standalone build configuration. The standalone build should just be `cmake <monorepo-root> -DLLVM_ENABLE_PROJECTS=standalone-project ...`. That means less build configuration to

Hello all, I have written a pass, which replaces condition branchinst using indirectBr to obfuscate program. The origin IR is as the following: br i1 %1, label %2, label %3 And the transformed IR is as the follwoing: %4 = select i1 %1, i8* blockaddress(@func, %2), i8* blockaddress(@func, %3) indirectbr i8* %4, [label %2, label %3] The pass's core function is as the

Hi! I sometimes build LLVM with a static libc++.a in MacOS, so that I use the LLVM libc++ instead of the system-wide one. However, when doing so, I always get link errors when building LLVM, because the build system links with libc++.a, but not with libc++abi.a and so there are quite a few missing symbols that the linker cannot find. My workaround (which always seems to work) is to embed
