 |
|
I have some data compressed with lzo2.02 on a 64 linux platform. I
can uncompress the data on that platform just fine. I then move the
compressed data over to a 32 bit linux platform and try to uncompress
it. The decompression functions don>t think the data is compressed.
I think the problem is the dictionary of common strings (sorry if this
not standard terminology) is constructed using data of type lzo_uint.
The size of this data type is 64 bits on the 64 bit platform and 32
bits on the 32 bit platform.
I>m about to hack around with lzo2 to create a decompress function for
32 bit platforms that understands compressed data produced on 64 bit
platforms.
Does anyone know if this problem has already been encountered and
fixed?
Am I misunderstanding what the problem is?
Thanks,
Paul |

I found out what is wrong. The compressed file format is portable
between 32 and 64 bit intel platforms. Please disregard my
baltherings.
