mkisofs: Value too large for defined data type.

["Paul Smith" <phhs80@xxxxxxxxx>]

Dear All

I am trying to create an iso file with the command mkisofs, but
getting the following problem:

$ mkisofs -r -R -J -l -L -max-iso9660-filenames -V "ISOS 22" -o
~/Desktop/isos22.iso .
mkisofs: The option '-L' is reserved by POSIX.1-2001.
mkisofs: The option '-L' means 'follow all symbolic links'.
mkisofs: Mkisofs-2.02 will introduce POSIX semantics for '-L'.
mkisofs: Use -allow-leading-dots in future to get old mkisofs behavior.
Warning: creating filesystem that does not conform to ISO-9660.
Warning: ISO-9660 filenames longer than 31 may cause buffer overflows in the OS.
INFO:   ISO-8859-1 character encoding detected by locale settings.
       Assuming ISO-8859-1 encoded filenames on source filesystem,
       use -input-charset to override.
mkisofs: Value too large for defined data type. File ./myfile.iso is
too large - ignoring

myfile.iso is a 4,1GB file.

Any ideas?

Thanks in advance,

Paul
