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 or 2.7.0 compile. 

 The issue is with miniruby.exe - it gets build but does not work. For example: 

 $ ./miniruby.exe -v 

 Returns nothing (I assume its crashing but its 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".
