Subject: [ruby-core:109020] [Ruby master Bug#18808] Cannot compile ruby 3.1.2 on powerpc64le-linux without disabling the jit features

Issue #18808 has been updated by jaruga (Jun Aruga).


@npn What is the gcc version are you using on the RHEL 7? Are you using a default system gcc maybe 4.8?

For example, in the latest Red Hat Software Collections 3.8 that you can install to RHEL 7, there is a SCL devtoolset-11 including gcc 11.2 according to the document. Why don't you use the newer version?
See <https://access.redhat.com/documentation/en-us/red_hat_software_collections/3/html/3.8_release_notes/chap-rhscl>.

----------------------------------------
The system I am trying to compile on is a ppc64el system running RedHat 7 (3.10.0-1160.62.1.el7.ppc64le).  I can successfully compile on a x86_64 system running the same version RedHat 7 (3.10.0-1160.62.1.el7.x86_64)

When I configure with the following,  make completes fine,  but if I remove the `--disable-jit-support` it fails with the following error.


     ./configure --enable-shared --enable-load-relative  --disable-install-doc --prefix=$RUBY_PREFIX --exec-prefix=$RUBY_PREFIX/rh_ppc --disable-jit-support
