[jira] [Updated] (HADOOP-8538) CMake builds fail on ARM

["Trevor Robinson (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-8538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Trevor Robinson updated HADOOP-8538:
------------------------------------

    Attachment: hadoop-cmake.patch

Patch CMake files to add -m32 compile/link flag only when using GCC on 64-bit platforms. Verified that native libraries build correctly on amd64 with 32-bit and 64-bit JVM and on ARM.

> CMake native builds fail with this error:
> cc1: error: unrecognized command line option '-m32'
> -m32 is only defined by GCC for x86, PowerPC, and SPARC.
> The following files specify -m32 when the JVM data model is 32-bit:
> hadoop-common-project/hadoop-common/src/CMakeLists.txt
> hadoop-hdfs-project/hadoop-hdfs/src/CMakeLists.txt
> hadoop-tools/hadoop-pipes/src/CMakeLists.txt
> hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/CMakeLists.txt
> This is a partial regression of HDFS-1920.
