Create a directory in which we can't write to and use this as the location
|
||
|
|
where Dune is supposed to store the cache:
|
||
|
|
|
||
|
|
$ mkdir readonly
|
||
|
|
$ chmod a-w readonly
|
||
|
|
$ export DUNE_CACHE=enabled
|
||
|
|
$ export DUNE_CACHE_ROOT=$(pwd)/readonly/cache-dir
|

|
|
|
||
|

$ dune build
|

|
|
Warning: Cache directories could not be created: Permission denied; disabling
|

cache
|

Hint: Make sure the directory
|
||
|
|
$TESTCASE_ROOT/readonly/cache-dir/temp
|
||
|
|
can be created
|
||

|
||
|

Likewise, this should also happen if the location is set via XDG variables.
