Issue #21917 has been updated by mhashizume (Michael Hashizume). Thanks for the quick reply. Your second, more simple patch in https://bugs.ruby-lang.org/issues/21917#note-2 worked to resolve my build issue. I also tried your commit 361644c0cce3235e9cc6724994c6b5711deb10b8 but the build fails with a different issue: ```shell compiling strscan.c installing default strscan libraries strscan.c:621:1: error: static declaration of 'rb_reg_onig_match' follows non-static declaration 621 | rb_reg_onig_match(VALUE re, VALUE str, | ^~~~~~~~~~~~~~~~~ In file included from strscan.c:12: ../.././include/ruby/re.h:149:14: note: previous declaration of 'rb_reg_onig_match' was here 149 | OnigPosition rb_reg_onig_match(VALUE re, VALUE str, | ^~~~~~~~~~~~~~~~~ gmake[3]: Leaving directory '/var/tmp/tmp.DXpB2u0vTN/ruby-4.0.1/ext/strscan' gmake[3]: *** [Makefile:269: strscan.o] Error 1 gmake[2]: *** [exts.mk:322: ext/strscan/all] Error 2 gmake[2]: *** Waiting for unfinished jobs.... linking shared-object stringio.so gmake[3]: Leaving directory '/var/tmp/tmp.DXpB2u0vTN/ruby-4.0.1/ext/stringio' linking shared-object ripper.so ``` ---------------------------------------- Bug #21917: Unable to build 4.0.1 on AIX 7.2 https://bugs.ruby-lang.org/issues/21917#change-116506 * Author: mhashizume (Michael Hashizume) * Status: Closed * ruby -v: 4.0.1 * Backport: 3.2: DONTNEED, 3.3: DONTNEED, 3.4: DONTNEED, 4.0: REQUIRED ---------------------------------------- I'm attempting to build Ruby 4.0.1 on AIX 7.2. We have had successful builds of previous versions of Ruby on this platform, but are starting to see an issue when using miniruby to build Ruby: ``` shell ./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems -r./powerpc64-aix7.2.0.0-fake ./tool/rbinstall.rb --make="gmake" --dest-dir="" --extout=".ext" --ext-build-dir="./ext" --mflags="-j3 --jobserver-auth=fifo:/tmp//GMfifo9306586" --make-flags=" -j3 --jobserver-auth=fifo:/tmp//GMfifo9306586" --data-mode=0644 --prog-mode=0755 --installed-list .installed.list --mantype="man" --install=all --exclude=doc /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/common/monitor.rb:10:in 'Kernel#require': false() function is unimplemented on this machine (NotImplementedError) from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/common/monitor.rb:10:in '<top (required)>' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in '<top (required)>' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in 'Kernel#eval' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in '<top (required)>' from ./tool/rbinstall.rb:25:in 'Kernel#require' from ./tool/rbinstall.rb:25:in '<main>' ``` I'm not sure where the NotImplementedError is coming from, and when looking at the `truss` output from miniruby, I see a ENOTTY when miniruby attempts to load monitor.so: ```shell accessx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/powerpc64-aix7.2.0.0/monitor.so", 0, 0) = 0 statx("/", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp/tmp.INfzUXAeGi", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/powerpc64-aix7.2.0.0", 0x0FFFFFFFFFFFA680, 176, 011) = 0 statx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/powerpc64-aix7.2.0.0/monitor.so", 0x0FFFFFFFFFFFA680, 176, 011) = 0 __ksetjmp(0x0000000110019F88, 0x09000000026845A8, 2, 0x000000011001A1D8, 0x0FFFFFFFFFFFB790, 0x0000000022242202, 0x000000011011A658, 0x09000 00000260348) = 0 statx("/var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/powerpc64-aix7.2.0.0/monitor.so", 0x0FFFFFFFFFFFB800, 176, 0) = 0 kioctl(2, 22528, 0x0000000000000000, 0x0000000000000000) Err#25 ENOTTY /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/common/monitor.rb:10:in 'Kernel#require': false() function is unimplemented on this machine (NotImpl ementedError) from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/.ext/common/monitor.rb:10:in '<top (required)>' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in '<top (required)>' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in 'Kernel#eval' from /var/tmp/tmp.INfzUXAeGi/ruby-4.0.1/lib/rubygems.rb:1452:in '<top (required)>' from ./tool/rbinstall.rb:25:in 'Kernel#require' from ./tool/rbinstall.rb:25:in '<main>' ``` monitor.so is present in the path that miniruby is looking for it. Any pointers on where to start debugging this further or what changes in more recent versions of Ruby could have caused this would be greatly appreciated. Thank you! -- https://bugs.ruby-lang.org/
