Feature #16650

Updated by cfis (Charlie Savage) about 4 years ago

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 its s 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".
