Exception in zlinux machine(s390x-Linux) #39

Closed praveenjala closed 7 years ago

praveenjala commented 7 years ago

Hi,

I am using docker-java(3.0.6) client to connect to Docker. When i am trying to connect in zlinux machine(s390x-Linux) i am getting error with following: Caused by: java.lang.RuntimeException: Unhandled architecture/OS: s390x-Linux mtcac_1 | at org.newsclub.net.unix.NarSystem.getAOLs(NarSystem.java:110) mtcac_1 | at org.newsclub.net.unix.NarSystem.loadLibrary(NarSystem.java:30)

Please find the complete log in the attached log file.

Can you please help me in resolving this as early as possible?

Thanks, Praveen. unixsockerror.txt

Hi Praveen,

s390x is an unsupported architecture (see the error message). You need to build a matching binary on/for your platform. (see the "junixsocket-native" Maven artifact) Let me know how that goes.

Cheers, Christian

Hi Christian,

Thanks a lot for you immediate reply. Do you want me to follow the steps given in this page https://code.google.com/archive/p/junixsocket/wikis/BuildingFromSource.wiki This page refers to build.xml, but i can find only pom.xml file.

How to update NarSystem.java file to include s390x-Linux?

Can you please give detail description of how to do?

Thanks, Praveen.

kohlschuetter commented 7 years ago

The Wiki on Google Code is outdated.

Please try the following:

  1. Checkout the source from https://github.com/kohlschutter/junixsocket
  2. mvn clean install -Pwith-native
  3. nar file should be in ~/.m2/repository//com/kohlschutter/junixsocket/junixsocket-native/2.0.5-SNAPSHOT/

If that works, check out the git tag corresponding to the version you want to use and try again

praveenjala commented 7 years ago

I have to build on zlinux machine, to generate the corresponding libs. Am i correct.

kohlschuetter commented 7 years ago

That would be preferable. I guess you could also build in an emulator or attempt cross-compilation. In any case, you're pretty much on your own here as I do not have access to such mainframes.

Hi Kohlschuetter,

I tried to build the jar by checking out the code from git. Initially i got the following error [‎6/‎5/‎2017 3:16 PM] Chakravarthula, Shivaramakrishna: [ERROR] Failed to execute goal com.github.maven-nar:nar-maven-plugin:3.2.0:nar-validate (default-nar-validate) on project junixsocket-native: NAR: One of two things may be wrong here: [ERROR] [ERROR] 1. tag is missing inside the tag of your NAR configuration [ERROR] [ERROR] 2. no linker is defined in the aol.properties file for 's390x.Linux.linker'

After adding the following lines to aol.properties file s390x.Linux.gpp.c.options=-Wall -Wno-long-long -Wpointer-arith -Wconversion -m64 -march=s390x s390x.Linux.gpp.cpp.options=-Wall -Wno-long-long -Wpointer-arith -Wconversion -m64 -march=s390x s390x.Linux.gpp.linker.options=-shared -shared-libgcc -fPIC -fexceptions -m64 -march=s390x s390x.Linux.linker=g++

I was able to build the jar file. But on opening the jar file "junixsocket-native-common-2.0.5-SNAPSHOT.jar" there is no lib directory in the jar file. Ideally there should be a lib directory containing the files which is present in 2.0.4 file.

I have attached the jar file. Please let me know what i am doing wro native-common-jarfile.zip ng as early as possible. Thanks, Praveen.

All the junit testcases are failing.

praveenjala commented 7 years ago

Hi Kohlschuetter,

Can you please let me know what i am doing wrong. I am struck.

Thanks, Praveen.

kohlschuetter commented 7 years ago

Modify junixsocket-native-common/pom.xml so it includes your nar.

praveenjala commented 7 years ago

Hi Kohlschuetter;,

I tried building with your suggestion. But i am not succesful.

I have attached a zip file containing the pom.xm and the output of the command.

Can you have a look and let me know what is work?

Now also no lib directory is not created containing the so files. Please help me sir i am struck.

Regards, Praveen

praveenjala commented 7 years ago

junixsocket.zip Attached the zip file.

kohlschuetter commented 7 years ago

Sorry, I don't have time to debug this right now.

You are trying to build on an unsupported architecture; junixsocket tells you this by throwing an exception "Unhandled architecture/OS: s390x-Linux".

kohlschuetter commented 5 years ago

For posterity: cross-compilation has become much easier with junixsocket 2.2.

see Cross-compiling junixsocket and Custom architectures for some information.
