Issue #18808 has been updated by k0kubun (Takashi Kokubun). Status changed from Assigned to Closed I replaced the build process in [Feature #19420], and this issue seems irrelevant to today's build system. Closing. ---------------------------------------- Bug #18808: Cannot compile ruby 3.1.2 on powerpc64le-linux without disabling the jit features https://bugs.ruby-lang.org/issues/18808#change-102187 * Author: npn (John Davis) * Status: Closed * Priority: Normal * Assignee: k0kubun (Takashi Kokubun) * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- 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 building rb_mjit_header.h rb_mjit_header.h updated building .ext/include/powerpc64le-linux/rb_mjit_min_header-3.1.2.h error in final header file: In file included from /tmp/20220525-12786-q2ndz2.c:1:0: /tmp/20220525-12786-vf3xbh.h:16627:1: error: multiple storage classes in declaration specifiers __attribute__ ((__visibility__("default"))) extern ^ compilation terminated due to -Wfatal-errors. make: *** [.ext/include/powerpc64le-linux/rb_mjit_min_header-3.1.2.h] Error 1 ---Files-------------------------------- config.log (1.45 MB) rb_mjit_min_header-3.2.0.h (1000 KB) rb_mjit_header.h (1010 KB) rb_mjit_header.h (1010 KB) config.log (1.37 MB) -- https://bugs.ruby-lang.org/
