how to make rockbox support >4G file?

[powerpan]

what I could do to make it support a big file > 4G?

FAT32 doesn't support 4GB files, so I guess you'd have to add support for another file system.

Its probably easier to just not use >4GB files.

I ported rockbox on linux, so I need 4G file support

I'm pretty sure that Rockbox as an Application isn't bound by the FAT32 restriction.  The host operating system should handle file system access in that case.

but the data structure will limit this.
like size of off_t, I think there might be more than this limits the decode for large file.

uncompress file and lossless file will easily break 4G limit.

I'm starting to port it to support upnp, like renderer to be control by remote computer/android pad. file size will be a headache later while it could access NAS.

Various things will need to use off_t or fpos_t instead of long - the system headers should hopefully be defining those as 64-bit on platforms that support it. We may also need to change the firmware layer for RaaA to call 64-bit file APIs where available.

It shouldn't be too difficult, though. Patches are welcome.

several decoders don't handle files larger than 2G/4G at the moment even if the formats techincally support them
