Unzip 6.0 won't work on large file zipped with Zip 3.0

Jim Pickard — Thu, 01 Apr 2010 20:07:38 GMT

I downloaded and built Zip 3.0 and UnZip 6.0 on VMS 7.3-2 Alpha from ftp://ftp.info-zip.org/pub/infozip/vms/ but am unable to get them to zip and unzip a large (10+GB) file:

Directory CLIENT1109:[FMC215]

TRANSREP.CUS;1 21108760/21108768 29-MAR-2010 20:00:08.77

Total of 1 file, 21108760/21108768 blocks.

$ ZIP BIGTEST TRANSREP.CUS
adding: transrep.cus
(deflated 89%)

$ unzip -o bigtest.zip
Archive: CLIENT1109:[FMC215]BIGTEST.ZIP;1
skipping: transrep.cus need PK compat. v4.5 (can do v2.1)

$ zip -v

Works fine for smaller (50-100MB) files.

Do I need to specify any options on the zip or unzip to handle the large files?

Your unzip build lacked the LARGE_FILE_SUPPORT option.

Doh! Missed that during the build, likely from trying to do four things at once.

That fixed it, thank you very much.
