To do so, we usually need a custom g++.
ppc64le binary is built by @odaira, and I think his OS's glibc version is newer than yours.
For example, linux, x86_64 native libraries is built using a custom g++ to do static link to embed libc++ (https://github.com/xerial/snappy-java/blob/master/BUILD.md#building-linux-x86_64-binary)
If you build your own snappy-java, using
make nativecommand, it should work even in RHEL74. Generally speaking, to build snappy-java for supporting older glibc versions, we need to use really old versions of Linux.@xerial we have run into this as well.
We need to support RHEL7 on PPC - and RHEL7's glibc version is glibc 2.17+ ldd ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so: /lib64/ld64.so.2: version `GLIBC_2.22' not found (required by ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so) linux-vdso64.so.1 => (0x00003fff7d300000) libm.so.6 => /lib64/power8/libm.so.6 (0x00003fff7d050000) libc.so.6 => /lib64/power8/libc.so.6 (0x00003fff7ce70000) /lib64/ld64.so.2 (0x0000000047020000)This is not a problem with snappy-java's builds on x86 - these work fine on RHEL7 - so they must be built against an older glibc than that used on ppc64le.
Could you please reconsider & do a build and release which is compatible with RHEL on ppc64le?
We would really prefer not to maintain a forked build - but could provide a build of libsnappyjava.so built on RHEL7/ppc64le if you would consider releasing it.
edit:
Please note that the prior ppc64le build worked on RHEL7 --#!/bin/bash set -x uname -a lsb_release --all git log -n 3 --date=iso ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so echo "The current build" git checkout 13299c1fda0df153d5ec651f829e861d28d2b9be ldd ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so echo "The prior build" git checkout 4ff7447abf8a5fa24c366e7637bd44e597a60c47 ldd ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so$ ./do + uname -a Linux rhel71-ppc-dev.pic.build.10gen.cc 3.10.0-229.ael7b.ppc64le #1 SMP Fri Jan 30 12:03:50 EST 2015 ppc64le ppc64le ppc64le GNU/Linux + lsb_release --all LSB Version: :core-4.1-noarch:core-4.1-ppc64le Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 7.1 (Maipo) Release: 7.1 Codename: Maipo + git log -n 3 --date=iso ./src/main/resources/org/xerial/snappy/native/Linux/ppc64le/libsnappyjava.so commit 13299c1fda0df153d5ec651f829e861d28d2b9be Author: Rei Odaira <[email protected]> Date: 2017-11-16 13:15:41 -0600 Update Linux/ppc64le/libsnappyjava.so commit 4ff7447abf8a5fa24c366e7637bd44e597a60c47 Author: Taro L.

If we can create a docker image that contains a cross compiler for ppc64le and uses an older version of glibc (e.g., REHL7), we can build a binary for your environment by simply changing this line:
https://github.com/xerial/snappy-java/blob/master/Makefile#L204It should be fixed in snappy-java 1.1.7.4
java.lang.UnsatisfiedLinkError: /tmp/snappy-1.1.7-47312095-8ab9-48a7-885f-cea7c7614fd6-libsnappyjava.so: /lib64/ld64.so.2: version `GLIBC_2.22' not found (required by /tmp/snappy-1.1.7-47312095-8ab9-48a7-885f-cea7c7614fd6-libsnappyjava.so)
Any specific reason why this dependecy is introduced in the first place?
Secondly, I couldn't find the GlibC 2.22 for ppc64le for RHEL74 and RHEL75 , in that case can snappy be compiled with GLIB2.17 itself ?
