Subject: [ruby-core:44824] [ruby-trunk - Bug #6391] Segment Fault while execute make_encmake.rb for Ruby 1.9.3 P194 ( MinGW64)


Issue #6391 has been updated by raylinn@gmail.com (ray linn).


Here is the update:

1. I renamed my folder local to local.old, so that any 3rd partt lib will not be linked.
2. Rolled back GCC from 4.7.0 to 4.6.2.
3. just use the following command to configure : ./configure --build=x86_64-w64-mingw32 CFLAGS="-Ox" x will be replaced as 2 or 3.

after took all these actions, I got the following result:

1. Ruby 1.9.3P0                      x=3 passed; x=2 failed
2. Ruby 1.9.3P194                    x=3 passed; x=2 failed
3. Snapshot {ruby 2.0.0)             x=3 passed; x=2 failed.

ruby -v: ruby 1.9.3p194 (2012-04-20) [x64-mingw32]


The Ruby is compiled by MinGW64 (GCC 4.7.0 ), configure script is :

./configure --build=x86_64-w64-mingw32 CFLAGS="-O2 -mieee-fp -I/usr/local/include" LDFLAGS="-L/usr/local/include"

when miniruby executing, error occurs with the following message:


        CC = gcc
        LD = ld
        LDSHARED = gcc -shared
        CFLAGS = -O2 -mieee-fp -I/usr/local/include
        XCFLAGS = -include ruby/config.h -include ruby/missing.h -fvisibility=hi

        CPPFLAGS =   -I. -I.ext/include/x64-mingw32 -I./include -I.
