Re: [ccache] ccache error: Failed to create temporary file... Read-only file system

Strange - I don't think - I fail to see any somewhat valid reason that - 
it makes sense to try to get ccache to work with a read-only cache 
directory 


Even if one disables all statistic stuff (in case that is possible - I 
never tried that) 



Error came up as a complete surprise, and I just wanted to verify whether any 
changes were made to ccache-4 that would throw up that warning.
I will keep investigating and will report back here, if I overcome this hurdle.


Kind regards,
Bernd

ccache *caches* something and writes the cache to some filesystem.
Obviously, that should be - thus - writable.
And obviously, the home directory of that use (or at least the
/home/ck/.ccache directory) is on a read-only mounted filesystem.

You need to tell more about your compiling environment (I never built
something for Android anywhere ...).

Oh.. Sorry for not elaborating.
The system worked fine earlier, in the same environment, where .ccache 
directory was read-write mounted system. No changes have been made to the 
configuration.

I am trying to build bootimage from kernel sources for android. I have ccache 
enabled with max_size 90G.
The ccache version is 4.2.1

Compilation stops, throwing a "ccache error: Failed to create temporary file 
/home/ck/.ccache/tmp/tmp.a.Xdafd Read only file system".

Can anyone help or show some resources to read/refer ?


Any basic Unix book/documentation should mention "rw vs ro" mounts of 
filesystems (of any type) ...
