ccache: error: Failed to create directory /home/toufu/.ccache/tmp: Read-only file system

20:56:21 ninja failed with: exit status 1

#### failed to build some targets (02:36 (mm:ss)) ####

 

I didn't get such an error on Android 11.

How can I solve it?

[Chang Kyo]

[current workaround]

a. disable ccache  (will impact compiling speed)

b. let ccache and AOSP source code to different partition (if your tmpfs bigger enough or you already had another partition)

c. mount --bind allow you put ccache and AOSP source code in the same partition.(reference: https://stackoverflow.com/questions/61923015/ccache-fails-with-read-only)

[root cause]

Need to check which commit cause it check this rule when AOSP building.

Because before Android 12, ccache files and AOSP source code in the same partition works fine.
If someone knowledge root case, please share with us.

Thanks a lot.
