Resolution: Duplicate
> Native code needs to be built to match the 32/64 bitness of the JVM
> -------------------------------------------------------------------
>
> Key: HADOOP-11975
> URL: https://issues.apache.org/jira/browse/HADOOP-11975
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: build
> Affects Versions: 2.7.0
> Environment: Solaris
> Reporter: Alan Burlison
> Assignee: Alan Burlison
>
> When building with a 64-bit JVM on Solaris the following error occurs at the
> link stage of building the native code:
> [exec] ld: fatal: file
> /usr/jdk/instances/jdk1.8.0/jre/lib/amd64/server/libjvm.so: wrong ELF class:
> ELFCLASS64
> [exec] collect2: error: ld returned 1 exit status
> [exec] make[2]: *** [target/usr/local/lib/libhadoop.so.1.0.0] Error 1
> [exec] make[1]: *** [CMakeFiles/hadoop.dir/all] Error 2
> The compilation flags in the makefiles need to explicitly state if 32 or 64
> bit code is to be generated, to match the JVM.
