Mac OS X installation for 1.9.2 (rvm)

[ababich]

for 0.8.2 Mac OS X installation fails using

gem install ruby-stemmer

in case of badly compiled libstemmer.o

you have two bugs in extconf.rb where you attempt to determine arch for macs

I haven't tried to fix determination logic but fixed the mistake which blocked ARCH forced by external param. You need to change

unless ENV['ARCHFLAGS'].nil?

to

if ENV['ARCHFLAGS'].nil?

this allows you to start process correctly via ARCHFLAGS='-arch x86_64' gem install ruby-stemmer

but to finish it ok you need to use ranlib for libstemmer.o

so, I've added

if RUBY_PLATFORM =~ /darwin/
system "ranlib #{File.expand_path(File.join(LIBSTEMMER, 'libstemmer.o'))}"
end

after "#{make} libstemmer.o" case and built with this fixes gem was successfully installed under rvmed 1.9.2 ruby on Mac OS X 10.6 via "ARCHFLAGS='-arch x86_64' gem install ruby-stemmer" command

please investigate, and probably add these fixes to next version

Hi ababich,

Thanks for reporting this.

Somehow it works for me under Mac OS X 10.6.6 with ruby 1.9.2p136 under rvm 1.2.7:

$ rvm use ruby-1.9.2-p136
$ ruby -v
ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-darwin10.5.0]
$ gem -v
1.3.7
$ gem install ruby-stemmer

There must be some particularity of you system, can you please post more details?

1. What's the exact failure?
2. What gives you: %x[file #{File.expand_path(File.join(Config::CONFIG['bindir'], Config::CONFIG['RUBY_INSTALL_NAME']))}] if you run it in an irb session?
3. What's the output of echo $ARCHFLAGS (in bash or in your shell)?
4. Can you post (e.g. in a gist / pull request) your changes?

For a history of issues related with compilation problems on Mac OS X, please check: issue 3, issue 5 and issue 6.

1.

Your way didn't work for me and no solution was found, so what I did to solve the problem

https://gist.github.com/860186

This was caused by failing compilation of comptest.c using libstemmer.o in includes

https://gist.github.com/860194

This can be fixed using ranlib:

$ ranlib libstemmer_c/libstemmer.o

I've added a patch to extconf.rb:
# make libstemmer_c. unless we're cross-compiling.
unless RUBY_PLATFORM =~ /i386-mingw32/
system "cd #{LIBSTEMMER}; #{make} libstemmer.o; cd #{ROOT};"
exit unless $? == 0
end
if RUBY_PLATFORM =~ /darwin/
system "ranlib #{File.expand_path(File.join(LIBSTEMMER, 'libstemmer.o'))}"
end

last three lines - is my addition

after that it was almost work but compiling fails with ld message:
archive member '' with length 0 is not mach-o or bitcode

with exact empty '' - I found that this should hint to wrong arch when compiling internals of libstemmer.o

So, I have to provide ARCHFLAGS.

2.

The expression you have provided fails:

$ irb ruby-1.9.2-p136 :001 > %x[file #{File.expand_path(File.join(Config::CONFIG['bindir'], Config::CONFIG['RUBY_INSTALL_NAME']))}]
NameError: uninitialized constant Object::Config
        from (irb):1
        from /Users/coyote/.rvm/rubies/ruby-1.9.2-p136/bin/irb:16:in `<main>'

And I didn't resolve this.

3.

$ echo $ARCHFLAGS
    <- EMPTY

So, I've noticed that logic is a bit wrong and changed clause in your code in extconf.rb:
- ENV['ARCHFLAGS']= "-arch " + %x[file #{File.expand_path(File.join(Config::CONFIG['bindir'], Config::CONFIG['RUBY_INSTALL_NAME']))}].strip!.match(/executable (.+)$/)[1] unless ENV['ARCHFLAGS'].nil?
+ ENV['ARCHFLAGS']= "-arch " + %x[file #{File.expand_path(File.join(Config::CONFIG['bindir'], Config::CONFIG['RUBY_INSTALL_NAME']))}].strip!.match(/executable (.+)$/)[1] if ENV['ARCHFLAGS'].nil?

in fact changed unless to if which allows me to provide external ARCHFLAGS

which makes me successful execution:

Please, investigate :)

[ababich]

Yeah, some issues like foo.txt I've sorted out too, but yesterday it was 0.8.2 and today a 0.8.5 :)

Hi ababich,

Thanks for providing those details.
One more thing, what's the value of your COMMAND_MODE?

You can get it by running:

$ echo $COMMAND_MODE

in your shell. If is not unix2003 can you change it with:

$ export COMMAND_MODE=unix2003

and then try to compile it again? ( gem install ruby-stemmer should do it )

Does it work?

Thanks again.

ps. yeah, bumped the version number earlier today.

NameError: uninitialized constant Object::Config #---> forgot to add but most likely you'll need require 'mkmf' before :|

Hi ababich,

So, what's the value of your COMMAND_MODE? (see this comment: https://github.com/aurelian/ruby-stemmer/issues#issue/9/comment/847166 )

I'm trying to figure-out a solution for your problem without forcing -arch flag (rumors that Apple compilers will drop it).

[ababich]

Oh, sorry - few moments

[ababich]

Without setting COMMAND_MODE still does not work with the same errors

[ababich]

Looks like everybody who uses iTerm instead of system Terminal.app may be affected by COMMAND_MODE issue and should add this export to ~/.profile by default

[aurelian]

Great!

Will try to come up with a proper fix soon (like exporting unix2003 in extconf.rb).

[aurelian]

bump to 0.9.1 (closed by b124b72)
