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.
Errata: Incorrect @stable ICU 4.0 tags in ICU4C (Bug #6435)
ICU4C 4.0 as shipped had several APIs incorrectly marked as '@stable 4.0' that should have been marked '@stable 3.8' following the ICU API Compatibility policy. This bug, #6435 has been corrected the post-4.0 trunk (r24395) as well as in the latest ICU 4.0 maintenance branch (r24398). The API Docs available on this download page and in the sidebar have been corrected, and an updated ICU4C 4.0 API Change Report is available. Please use this report instead of the one embedded in the ICU4C download.
