If I take the command from the page and add my triple like so:
$ cmake -G Ninja -S llvm -B build \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DLLVM_ENABLE_PROJECTS="clang" \ # Configure
-DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind;compiler-rt" \
-DLLVM_RUNTIME_TARGETS="aarch64-unknown-linux-gnu"
CMake Warning:
Ignoring extra path from command line:
" "
<...>
-- Build files have been written to:
/home/david.spickett/llvm-project/build -bash:
-DLLVM_ENABLE_RUNTIMES=libcxx;libcxxabi;libunwind;compiler-rt: command
not found
As the comment is after the backslash, it's considered part of the next
line. This comments out the ENABLE_RUNTIMES line and makes the
RUNTIME_TARGETS line look like another command.
To fix this, put the comment before the configure command.
I also moved the other inline comments (which are fine) closer to the
text since they don't have to line up with the configure one anymore.
The LLVM Compiler Infrastructure
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called "LLVM". This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Getting the Source Code and Building LLVM
Consult the Getting Started with LLVM page for information on building and running LLVM.
