Platform Installation Notes

Please be sure to view the readme.html that is included in ICU. Most installation questions can be answered there. The z/OS (OS/390) unpax-icu.sh script is required to unpackage the compressed tar file on z/OS, and the i5/OS (OS/400) unpax-icu.sh script is required to unpackage the compressed file on i5/OS.

The ICU4C 4.0 source downloads contains a pre-built .dat data archive with ICU's data rather than the data source files. This is to simplify the build process for the majority of users and to reduce platform porting issues. If you need the data source files for customization, then please download the ICU source code from SubVersion repository. If you need to remove data from ICU's data library, you can also consider using the new icupkg tool to modify the data built into ICU.
