Bug ID: 44888
Summary: "Clang - Getting Started" page says to use makefiles
Product: Documentation
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: General docs
Assignee: unassignedb...@nondot.org
Reporter: nbill...@google.com
CC: llvm-bugs@lists.llvm.org
The instructions for building clang (on Linux) at
https://clang.llvm.org/get_started.html say to configure cmake with "cmake
-DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm" and then to build
with "make".
This method of building is extremely slow compared with building with ninja. I
tried to follow these instructions naively and the build was so slow that,
after waiting about an hour it still self-reported about 12% progress. After
running "cmake -DLLVM_ENABLE_PROJECTS=clang -G Ninja ../llvm", and then
building with ninja, the entire build took at most 15 minutes.
Is it possible to at least describe both configurations so that readers don't
have to find and fix the issues with make on their own?
