cygwin-1.7, gcc4-4.3, and ruby-1.9. make btest #236 test_io.rb Segmentation fault

ruby 1.9.2dev (2009-04-08 trunk 23198) [i386-cygwin]


Cygwin 1.7 is currently under beta testing. It is currently at cygwin-1.7.0-46. If nothing goes overly wrong, the official 1.7.1 is planned to be released in June.

Two issues blocking the release are:

1) Stabilization of gcc-4.3; It is currently at gcc4-4.3.2-2, and several to-do's remain.
Hopefully it will get ready in gcc4-4.3.2-3.

2) Compilation of all packages using the stable gcc-4.3.

This bug report is about making ruby-1.9 ready for these new cygwin-1.7 and gcc-4.3. These are some of the patches required to make ruby trunk get compiled.

  • eval_intern.h [CYGWIN]: Remove #ifdef CYGWIN for _setjmp() and _longjmp(). Cygwin-1.7 has its own definition in /usr/include/machine/setjmp.h . This is the minimally required patch to make the compilation go through to the end.

With the above three patches, ruby-1.9.2-r23198 can get compiled with only one warning:

** Ruby is compiled with --enable-pthread, but your Tcl/Tk library
** seems to be compiled without pthread support. Although you can

This is expected because cygwin tcltk-20080420-1 is compiled without pthread support. But when I try to compile like

CC=gcc-4 configure --program-suffix="-19" --disable-pthread

compilation fails.

make: *** No rule to make target thread_.h', needed byminiprelude.o'. Stop.
*** ERROR: make failed

This is because THREAD_MODEL is empty in Makefile. Looking into, I can see that when

if test "$rb_with_pthread" = "yes";

is false and

case "$target_os" in

then THREAD_MODEL gets undefined. (when(mingw*) is true, THREAD_MODEL=win32.) If I compile like

CC=gcc-4 configure --program-suffix="-19" --disable-pthread

the compilation goes through to the end, and thread-win32.c seems to be used instead of thread-pthread.c. But the same warning persists.

** Ruby is compiled with --enable-pthread, but your Tcl/Tk library
** seems to be compiled without pthread support. Although you can

This is wrong because --disable-pthread is used. Looking into ext/tk/extconf.rb, I can see that this warning is emitted when

# check pthread mode
if (macro_defined?('HAVE_NATIVETHREAD', '#include "ruby.h"'))
# ruby -> enable
unless tcl_enable_thread
# ruby -> enable && tcl -> disable

But include/ruby/ruby.h has


without any #ifdefs. So the pthread mode check in ext/tk/extconf.rb always evaluates to be true even when pthread support is disabled. This should be corrected. If these issues are corrected, then ruby-1.9 trunk can get compiled without warnings.

When I tried make run or make runruby, it failed.

With this patch, the results of make run or runruby are

make run

Fnot ok system 9 -- .../ruby-1.9.2-r23198/sample/test.rb:1948:in `'

which is expected and good. miniruby.exe does not support euc-jp, shift_jis, windows-1251, cp932 in Encoding.name_list, so make run is expected to fail at that test. But the result of make btest is bad.

make btest-ruby also emits several errors, but I will submit it as another issue because this report is already too long...
