Issue #16650 has been updated by nobu (Nobuyoshi Nakada). Status changed from Open to Closed It seems working now, by compiling with gcc 10.1.0. ---------------------------------------- Feature #16650: Ruby 2.6.* and 2.7* no longer compile on latest Mingw64 https://bugs.ruby-lang.org/issues/16650#change-85774 * Author: cfis (Charlie Savage) * Status: Closed * Priority: Normal ---------------------------------------- Using the latest version of mingw64 and msys2, neither ruby 2.6.5 nor 2.7.0 compile. The issue is with miniruby.exe - it gets built but does not work. For example: $ ./miniruby.exe -v Returns nothing (I assume it is crashing but its not triggering windows just in time debugger so hard to tell). Because of this, the various build rules that miniruby.exe execute do not work. For example, generating encdb.h from a template. The error is non-obvious: ./miniruby.exe -I./lib -I. -I.ext/common ./tool/generic_erb.rb -c -o encdb.h ./template/encdb.h.tmpl ./enc enc make: *** [uncommon.mk:1070: encdb.h] Error 4198400 After experimentation, the problem is the inclusion of -pie in the link command to make miniruby.exe. This can be worked around by: ./configure --prefix=/ CPPFLAGS=-I/mingw64/include LDFLAGS=-L/mingw64/lib --enable-shared=yes --disable-pie Note the inclusion of "--disable-pie". --------------- $ gcc -v Using built-in specs.
