Issue #19268 has been updated by cfis (Charlie Savage). This is still happening in Ruby 3.2.2. I suspect I see this because I use mingw64 make versus msys make. ---------------------------------------- Bug #19268: Mingw64 Build Failure https://bugs.ruby-lang.org/issues/19268#change-104755 * Author: cfis (Charlie Savage) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x64-mingw-ucrt] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- For both Ruby 3.1.3 and Ruby 3.2.0, building on msys2/ucrt64 fails: ``` c linking miniruby.exe /usr/bin/sh: -c: line 1: syntax error near unexpected token `(' /usr/bin/sh: -c: line 1: `/usr/local/ruby/bin/ruby --disable=gems -n -e BEGIN{version=ARGV.shift;mis=ARGV.dup} -e END{abort "UNICODE version mismatch: #{mis}" unless mis.empty?} -e (mis.delete(ARGF.path); ARGF.close) if /ONIG_UNICODE_VERSION_STRING +"#{Regexp.quote(version)}"/o 15.0.0 ./enc/unicode/15.0.0/casefold.h ./enc/unicode/15.0.0/name2ctype.h' make: *** [uncommon.mk:878: .rbconfig.time] Error 2 ``` The fix that works for me is changing: ``` c -e '(mis.delete(ARGF.path); ARGF.close) if /ONIG_UNICODE_VERSION_STRING +"#{Regexp.quote(version)}"/o' \ ``` To ``` c -e "(mis.delete(ARGF.path); ARGF.close) if /ONIG_UNICODE_VERSION_STRING +\"#{Regexp.quote(version)}\"/o" \ ``` ``` -- https://bugs.ruby-lang.org/
