OpenSSL - Symbol not found _rb_cArray

[johnnyt]

Hey @AllenOtis or @timfel - I'm getting this error now when trying to load openssl:

-- RubyFile>>load  : loading $MAGLEV_HOME/lib/ruby/1.9/openssl.rb
ERROR 2702 , a RubyLoadError occurred (error 2702),
dlopen(...maglev/ruby/1.9/openssl/ext/openssl.bundle, 265): Symbol not found: _rb_cArray
  Referenced from: ...maglev/lib/ruby/1.9/openssl/ext/openssl.bundle
  Expected in: flat namespace
 in ...maglev/lib/ruby/1.9/openssl/ext/openssl.bundle (LoadError)
topaz 1> exit

any thoughts?

Is this Darwin or Linux ?
Does it work on Linux ?
Did work using the 3.1.0.2.1 server ?

The basic tool for diagnosing symbol referencing errors like this is
to use nm
on both libraries involved, such as

nm -A *.so *.bundle | grep rb_cArray

rb_cArray should be exported by the
libgcilnk . In the C sources it is

ruby.h:RUBY_DLLSPEC extern VALUE rb_cArray;
rubycext.c:VALUE rb_cArray;

On Linux it is exported as a type "B" symbol .

libgcilnk-3.1.0.2.2-64.so:00000000006c4278 B rb_cArray

nm should show it in the ruby ssl library as an unresolved data reference.
all of this rb_ stuff could be moved to libmagparse eventually .

Awesome - I'll try those tips.

The error is on Darwin - I'll try it out tomorrow at work on Linux.

I see .c files in lib/ruby/1.9/openssl/ext in the maglev checkout,
What do I need to do to get the .o and shared libraries produced ?
i.e. ruby command line(s) to get to the point of the error you see ?

With the current MagLev build on darwin - after building/starting the stone just running this will get you the error:

maglev-ruby -e 'require "openssl"'

[AllenOtis]

I am getting to line 17 of lib/ruby/1.9/openssl.rb where the following
require fails

require 'openssl/ext/openssl'

For server development,
after doing a git checkout and bulding the server,
and in the git/src/kernel/parser do make clean ; make build ; make
install
to build the libmagparse,

I then load these 3 files into
a virgin stone with topaz
input $MAGLEV_HOME/src/smalltalk/baseruby.gs
input $MAGLEV_HOME/src/smalltalk/loadfiletree.gs
input $MAGLEV_HOME/src/smalltalk/ruby/allprims.gs

Then I am able to run vmunit tests, etc.
Not sure what I am missing to get further on the require openssl .

But I do think the server file rubycext.c should be moved from libgcilnk
to libmagparse , since that is where the rb_cArray symbol export problem
would have to be fixed, so I will work on that this week.

@AllenOtis:

To manually poke at this:

cd ext/openssl
ruby extconf.rb
make

There will be a file in there mkmf.log that will show the tests that it ran to determine eligibility. ext/extmk.rb is responsible for getting all ext's built from the top level. A plain make from the top should build all eligible extensions and their mkmf'log files should explain why they aren't.

[AllenOtis]

I think you mean
cd lib/ruby/1.9/openssl/ext
ruby extconf.rb

which yields
% ruby extconf.rb
extconf.rb:17:in `require': no such file to load -- mkmf (LoadError)
from extconf.rb:17

There is no extmk.rb anywhere in the maglev checkout .
And the only Makefile is src/kernel/parser/Makefile

I am working on a 3.1.0.2.3 server
that will move most of the ruby C extension support into libmagparse,
so we can fix whatever symbol exporting problems exist on Mac .
Should have this server build ready by July 21.

Believed fixed by the merge to master of 407 today.
