I am a bit confused, the patch you propose undo a patch that was added to support … ruby 1.9 on Fedora 17 (See root.cern.ch/viewvc/trunk/bindin … g#rev43004). Combined with the fact:[quote] the version of ruby packages is ruby{,-devel}-1.9.3.194-13. (though ruby -rrbconfig -e 'puts RbConfig::CONFIG["ruby_version"]' prints 1.9.1)[/quote]I wonder if in your case (or Matthias’ case) there was an installation problem for the ruby package?
Well, I looked into an old version of ruby (1.8.7) on a FreeBSD-9R machine and observed that there’re both
ID rb_frame_last_func _((void));
ID rb_frame_this_func _((void));
in /usr/local/lib/ruby/1.8/i386-freebsd9/intern.h.
I also confirmed the existence of the two in ruby-1.8.7 and the disappearance of the rb_frame_last_func in ruby-1.9.x by browsing rxr.whitequark.org/mri/ident?v=1 … _last_func and root.cern.ch/viewvc?view=rev&revision=16173 , and its correction by Matthias are correct and mine was nonsense…
I’ve also checked that the version-number pickup in the configure script and saw that it works fine. ; a build with the configure script (./configure linuxx8664gcc --enable ruby) finished succesfully
Well, this was my first build of ROOT using CMake and now I suspect the trouble might be due to CMake, although I know almost nothing about CMake…
My CMakeCache.txt contains the following lines; are these correct (“…: PATH=1” etc.)? How can I check that the version numbers are properly passed to bindings/ruby/src/drr.cxx etc?:
[code]//The Ruby major version
RUBY_VERSION_MAJOR:PATH=1
//The Ruby minor version
RUBY_VERSION_MINOR:PATH=9
//The Ruby patch version
RUBY_VERSION_PATCH:PATH=1[/code]
; a build with the configure script (./configure linuxx8664gcc --enable ruby) finished succesfully
