Hello!
I'm having case as follow.
$ export|grep CC
declare -x CCACHE_COMPRESS="1"
declare -x CCACHE_DIR="/var/tmp/ccache/"
declare -x CCACHE_DISABLE="1"
declare -x CCACHE_UNIFY="1"
$ ccache -V
ccache version 3.3.3
[...]
When I want to see stats I'm getting:
$ ccache -s
ccache: error: /var/tmp/ccache//ccache.conf: Permission denied
it's ok. Problem appears in such ccache invocation:
$ ccache gcc
ccache: error: /var/tmp/ccache//ccache.conf: Permission denied
man page says:
" The priority of configuration settings is as
follows (where 1 is highest):
1. Environment variables.
"
So if I set CCACHE_DISABLE=1 is any reason to read other variables from
config files?
Should be "Permission denied" error in reading conf files critical?
Wouldn't be better to omit such conf file and emit warning only?
Marcin
