9 years ago There are multiple approaches to get the build sail through on ppc64le:
Approach 1 -> First install libxslt-1.1.28-5.ael7b.ppc64le rpm that is part of RHEL 7.1 distro -> Then build nokogiri gem by making use of the system library : "gem install nokogiri -- --use-system-libraries"
Approach 2 -> Build a local copy of the libxslt either by downloading the latest tarball and patching it OR with the latest git checkout of libxslt (which builds fine as right updated config.guess would get picked up by automake) -> Then build nokogiri using "--with-xslt-dir=DIR / --with-xslt-config=CONFIG " options and point to the dir where local libxslt is built.
Both these approaches have pros & cons: Pros : The build is successful. Cons : As per http://www.nokogiri.org/tutorials/installing_nokogiri.html#using_your_system_libraries this may be unsupported & users are warned on the same.
Approach 3 which seems to be the right approach is to -> Patch nokogiri to pull new libxslt tarball (would require a newer tarball with updated config.guess be made available at ftp://ftp.xmlsoft.org/libxml2/) OR -> Ensure that after un-tarring the current libxslt tarball, config.guess is either patched / picked rightly from the system (either from latest automake / libtool or redhat-rpm-config ) which has support for ppc64le arch.

On an RHEL 7.1 LE (ppc64le) OS, I tried installing 'nokogiri' gem using "gem install nokogiri" and the install fails while building the embedded libxslt sources (v1.1.28). Attached are the gem_make.out and libxslt 1.1.28 config error seen while building the native gems.
When I install below required libxml2 and libxslt rpms from the distro DVD and then try "gem install nokogiri -- --use-system-libraries", the installation succeeds.
[u0011847@sys-71809 ~]$ rpm -qa | grep libxslt libxslt-devel-1.1.28-5.ael7b.ppc64le libxslt-1.1.28-5.ael7b.ppc64le [u0011847@sys-71809 ~]$ rpm -qa | grep libxml libxml2-devel-2.9.1-5.ael7b.1.ppc64le libxml2-python-2.9.1-5.ael7b.1.ppc64le libxml2-2.9.1-5.ael7b.1.ppc64le [u0011847@sys-71809 ~]$
Please note that the version of libxslt available as part of RHEL 7.1 LE distro DVD and the version of embedded libxslt is the same.
First level of probe into the logs shows that the 'config.guess' and 'config.sub' in the embedded libxslt 1.1.28 are out-dated and needs to be patched / requires an update.
