invalid ELF header (Possible cause: endianness mismatch) error for sigar jar on ppc64le.

[rashmi-ibm]

Getting the below error when trying to use sigar jar on a ppc64le system during mvn build of the source project.

WARN 27-11 03:54:24,870 (SystemInfoFactory.java:initialize:311) -Native library not available on this platform: java.lang.reflect.InvocationTargetException:null -> org.hyperic.sigar.SigarException:/root/.m2/repository/org/hyperic/sigar/1.6.5.132-6/sigar-1.6.5.132-6.jar: /root/.m2/repository/org/hyperic/sigar/1.6.5.132-6/sigar-1.6.5.132-6.jar: invalid ELF header (Possible cause: endianness mismatch)

I was able to build sigar jar successfully on power. Need pointers on how this issue can be fixed.

From which source code you are building ? Also, paste all commands executed to build.

I am trying to build the Rhq repository which internally uses sigar.

Below are the commands used to build the repo.

git clone https://github.com/rhq-project/rhq.git
cp rhq/etc/m2/settings.xml ~/.m2/
cd rhq
mvn clean -Ddbsetup -Penterprise,dev install

Can you pls point me to the documentation as to how I can use the ppc64le specific generated sigar jar.

I build sigar.jar successfully. Where do I specify the .so file

ls -1 sigar-bin/lib
history.xml
libsigar-ppc64le-linux.so
sigar.jar

[rashmi-ibm]

I suspect the error I am getting is due to a mismatch thats happening in the sigar-dist zip file.

https://repository.jboss.org/nexus/content/groups/public/org/hyperic/sigar-dist/1.6.5.132-6/

The zip file contains platform specific so files and the power specific files are namely as shown below::
libsigar-ppc64-linux.so

on the current power machine when I run the build the so file that is generated is libsigar-ppc64le-linux.so

Any pointers how i can explicitly fix this out ???

[rashmi-ibm]

I manually added the libsigar-ppc64le-linux.so in the sigar-dist/1.6.5.132-6/sigar-dist-1.6.5.132-6.zip file and tried to build the RHQ project.
The above sigar error went off with the above temporary fix.

Can you please help to add the libsigar-ppc64le-linux.so in the maven published version of sigar-dist.

It looks like sigar required for RHQ is from private redhat repository. Also, this project is quite inactive these days. I would suggest to contact admins on RedHat side ( https://github.com/rhq-project/rhq) and ask them if it is possible. For now, if you can fork the project, you can add additional step in ma
