Android O ccache record full path in .ccache folder

[jimmy...@fih-foxconn.com]

Hi, I saw .ccache record full build source code path, it will not re-use in different directory, even same source code.

Android N doesn't have this issue?

Does Android O need set other flag?

I posted a part of content for reference.

Hello, 

Have you tried upgrading the ccache version , or tried using the ccache from your Host machine.

I upgraded to the latest version(CCACHE 3.4.2+38_g13377bb) of ccache binary (compiled on my own)

with the following setting in ccache i could able to over the issue you have mentioned, 

/prebuilts/misc/linux-x86/ccache/ccache --set-config=hash_dir=false"

Regards
