Re: [android-building] how to get compile_commands.json by mma or mm from android.mk in aosp project of android 9

[Paschalis Mpeis]

In my case SOONG_GEN_COMPDB exists (android 10), but following the 
instructions here 

 did 
not generate the json file,
unless you actually proceed with a full build (i.e., make nothing didn't 
produce the file, and `m ` also didn't work.

But the suggested approach of building the json file using the output build 
log did work.
So you do the compilation as you would normally do (either full, or a 
subset), and then use the log file to generate the compdb like:

`compiledb --parse out/verbose.log`

Hi Dan. It looks like the option SOONG_GEN_COMPDB is not available in Pie 
branches. Perhaps it was added later. I wish to make use of this option. 
Will it be safe to use soong from master branch with Pie source code ? Were 
any breaking changes made in soong since Pie was branched out ?

thanks, I've tried *compiledb-aosp.sh* in android-9.0.0_r34, but failed.
here is the out put

Re: [android-building] how to get compile_commands.json by mma or mm from android.mk in aosp project of android 9

[刘昊]

some module like frameworks/av is really hard to convert to Android.bp.  In
android-9.0.0_r34 , SOONG_GEN_COMPDB can't use directly, I need add related
file to aosp soong module, then recompile soong, then I can
SOONG_GEN_COMPDB, but the generated compile_commands is really big, like
83M. generated by CMakeLists.txt is much smaller. :)

Re: [android-building] how to get compile_commands.json by mma or mm from android.mk in aosp project of android 9

[Nick Diego Yamane]

An alternative option would be compiledb tool (
https://github.com/nickdiego/compiledb), which is able to parse compile
commands from a build log. Some years ago I've been able to parse
compilation database from some AOSP modules using a similar approach.

Re: [android-building] how to get compile_commands.json by mma or mm from android.mk in aosp project of android 9

['Dan Willemsen' via Android Building]

The ninja compilation database support doesn't work very well for our ninja
files due to kati using a rule per command. This upstream ninja feature
request may help, but that's assuming that whatever is parsing the compdb
files can understand the raw rules (which is usually a bash script, not
just a call to the compiler):
https://github.com/ninja-build/ninja/issues/1377

I'd recommend converting to Android.bp so that you can use SOONG_GEN_COMPDB.
