Bug ID: 40668
Summary: `ninja` does not rebuild if sources change
Product: lldb
Version: unspecified
Hardware: Macintosh
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: thelastmamm...@gmail.com
CC: llvm-b...@lists.llvm.org
I'm on OSX and follow the steps here: https://lldb.llvm.org/build.html
```
git clone https://github.com/llvm/llvm-project.git
cd llvm-project
mkdir build
cd build
cmake ../llvm -G Ninja -DLLVM_ENABLE_PROJECTS='clang;lldb'
ninja lldb
```
this works, but then if I change sources [1], nothing is rebuilt after `ninja
lldb`, which completes almost immediately:
```
ninja lldb
[1/1] Python script sym-linking LLDB Python API
```
## note:
here's the change I was trying to make:

if i modify llvm-project/lldb/tools/debugserver/source/MacOSX/MachTask.mm
no recompilation happens; ditto with
`source/Plugins/Process/Darwin/MachException.cpp`
