Library-only project generates an "empty" compile_commands.json

oatberry commented 3 years ago

What kind of issue is this?

[x] PlatformIO Core. If you’ve found a bug, please provide an information below.

Configuration

PlatformIO Version (platformio --version): 5.1.1

Description of problem

Steps to Reproduce

run $ pio run -t compiledb in a library that doesn't generate binaries

Actual Results

compile_commands.json contains only []

Expected Results

compile_commands.json should I think at least contain info for building the library objects

If problems with PlatformIO Build System:

The content of platformio.ini:

[native]
platform = native
test_transport = native
build_flags = -std=c++17
debug_build_flags = -g -DDEBUG
lib_ldf_mode = deep

[env:release]
extends = native
build_type = release

[env:debug]
extends = native
build_type = debug

Additional info

We have tests that we run natively as this library contains no embedded-specific behavior, just business logic. I would think this would enable generation of a useful compile_commands.json that I can feed to clangd...

Fixed in https://github.com/platformio/platform-native/commit/5124578abb60f04bdc48d521d9613686c5ef6f03

Please update dev-platform native to the latest version via pio update.
