>From 5e9e94d33342fb8aec1b7b864f2344790e392d4a Mon Sep 17 00:00:00 2001 From: Robin Caloudis <53619127+robincalou...@users.noreply.github.com> Date: Sun, 5 Nov 2023 13:34:29 +0100 Subject: [PATCH] [clang][docs] Improve "Obtaining Clang" section The documentation is written relatively to `clang-llvm`, not the root repository directory. Therefore, the `llvm-project` repo needs to be cloned into the existing directory `clang-llvm`. I added `mkdir ~/clang-llvm` to make the intent of creating an empty directory explicit. Furthermore, additional steps have been modified accordingly. --- clang/docs/LibASTMatchersTutorial.rst | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/clang/docs/LibASTMatchersTutorial.rst b/clang/docs/LibASTMatchersTutorial.rst index 2a58502a8de4e7..d2883688ebfacc 100644 --- a/clang/docs/LibASTMatchersTutorial.rst +++ b/clang/docs/LibASTMatchersTutorial.rst @@ -22,7 +22,7 @@ started guide <https://llvm.org/docs/GettingStarted.html>`_. .. code-block:: console - cd ~/clang-llvm + mkdir ~/clang-llvm && cd ~/clang-llvm git clone https://github.com/llvm/llvm-project.git Next you need to obtain the CMake build system and Ninja build tool. @@ -33,11 +33,11 @@ Next you need to obtain the CMake build system and Ninja build tool. git clone https://github.com/martine/ninja.git cd ninja git checkout release - ./bootstrap.py + ./configure.py --bootstrap sudo cp ninja /usr/bin/ cd ~/clang-llvm - git clone git://cmake.org/stage/cmake.git + git clone https://gitlab.kitware.com/cmake/cmake.git cd cmake git checkout next ./bootstrap @@ -50,7 +50,7 @@ Okay.
