Hello, Thank you for the info. Is there any way to tell fontconfig not to check the mtime of font directories? Since I have full control over fonts installed in the device, and I would be pregenerating the cache file, I would be happy to tell fontconfig to just use the cache file without any further checks. Other than that, is there a recommended procedure for this? (pregenerating cache files) Thank you, Guillermo 2016-08-17 4:21 GMT+02:00 Akira TAGOH <akira@xxxxxxxxx>: > Fontconnfig is checking the mtime of the directories fonts installed > to detect the changes. that message means the mtime of > /usr/share/fonts/X11 is different where the caches originally > generated. > > On Tue, Aug 16, 2016 at 9:13 PM, Guillermo Rodriguez Garcia > <guille.rodriguez@xxxxxxxxx> wrote: >> Hi all, >> >> I have an embedded system where the list of fonts is known in advance >> and cannot change.
