We don't have cups-devel
installed on our production system and therefore don't have libcups.so
, but only libcups.so.2
.
Therefore using ffi-cups
fails with LoadError: Could not open library 'cups': cups: cannot open shared object file: No such file or directory. Could not open library 'libcups.so': libcups.so: cannot open shared object file: No such file or directory
.
Giving the full filename via ENV['CUPS_LIB']
(as implemented in ffi-cups.rb
) does not work, because ffi-cups/ffi/array.rb
, ffi-cups/ffi/cups.rb
and ffi-cups/ffi/http.rb
don't honor the value from ENV, but always use ffi_lib('cups')
.
In lib/ffi-cups/printer.rb:60
: last_error = Cups.cupsLastErrorString()
.
I guess that should be FFI::Cups.cupsLastErrorString()
.
