ninja output empty compdb content

When i tried to integrate Google Kythe system with my own Android source code. And i found i need to generate compile_commands.json first.

So i run command prebuilts/build-tools/linux-x86/bin/ninja -f out/combined-$target.ninja -t compdb, however generate nothing.

$ prebuilts/build-tools/linux-x86/bin/ninja -f out/combined-venus.ninja -t compdb

And my version of ninja:

$ prebuilts/build-tools/linux-x86/bin/ninja --version
1.8.2.git

I also created a Helloworld project to do the samething, yet still nothing. Is it a known issue?

Solution

  • OK, it seems only latest ninja process could generate the json file. so i download from github and compile ninja myself. now it works
