Digest::Base problem

[Martin Hansen]

I have the following problem:

maasha@mel:~$ irb
irb(main):001:0> require 'digest'
=> true
irb(main):002:0> Digest::Base
NameError: uninitialized constant Digest::Base
from (irb):2
from /usr/bin/irb:12:in `<main>'


Apparently, there is something wrong my Ruby compilation.

I have compiled Ruby 1.9.1 and 1.9.2 on Mac, Ubuntu, and Redhat. Same
result. I suspect a missing dependency that don't raise the alarm.

Suggestions?

Do you have OpenSSL devel packages installed? Are they found by ./configure=
?

./configure?

It doesn't look like configure do anything ssl - should it?

maasha@maxwell:~/Install/src/ruby-1.9.2-p180$ ./configure | grep -i ssl

This is what's installed sslwise:

maasha@maxwell:~/Install/src/ruby-1.9.2-p180$ dpkg -l | grep -i ssl
ii libcurl4-openssl-dev 7.18.2-8lenny4
Development files and documentation for libc
ii libssl-dev 0.9.8g-15+lenny11
SSL development libraries, header files and
ii libssl0.9.8 0.9.8g-15+lenny11
SSL shared libraries
ii openssl 0.9.8g-15+lenny11

Yes. OpenSSL provides the crypto-backend that Ruby uses.

/configure --with-openssl=/path/to/shared/library.so

should do the trick, though, since you seem to have everything in
order, otherwise.

Yes. OpenSSL provides the crypto-backend that Ruby uses.

./configure --with-openssl=/path/to/shared/library.so

I dont get it. First of all configure complains:

configure: WARNING: unrecognized options: --with-openssl
configure: WARNING: unrecognized options: --with-ssl

Second: I have no idea of what path to point to.

Third: I tried to manually compile ext/openssl and recompile ext/digest,
but still no Digest::Base.



Martin

 

[Phillip Gawlowski]

I dont get it. First of all configure complains:

configure: WARNING: unrecognized options: --with-openssl
configure: WARNING: unrecognized options: --with-ssl

/configure --help should, well, help.

Second: I have no idea of what path to point to.

That's highly specific to your environment, but a "find libssl0.9.8"
should help.

Third: I tried to manually compile ext/openssl and recompile ext/digest,
but still no Digest::Base.

Yeah, those are stubs (i.e. they don't do anything). There once were
export restrictions in the US on almost all cryptography (technically,
crypto is a weapon as far as US export law is concerned).

I dont really see anything:

Hm, I see now that /usr/lib contains these:

/usr/lib/libssl.a
/usr/lib/libssl.so
/usr/lib/libssl.so.0.9.8
/usr/lib/libssl3.so
/usr/lib/libssl3.so.1d

But /usr/lib is included per default, right?

Crazy!

I have the following problem:

NameError: uninitialized constant Digest::Base

Apparently, there is something wrong my Ruby compilation.

Indeed

I have compiled Ruby 1.9.1 and 1.9.2 on Mac, Ubuntu, and Redhat. Same
result. I suspect a missing dependency that don't raise the alarm.

Ubuntu: apt-get install libssl-dev
Red Hat: yum install openssl-devel
Mac: are you using a "ports" system?

 

[Martin Hansen]

Ubuntu: apt-get install libssl-dev

Already there:

maasha@maxwell:~/Install/src/ruby-1.9.2-p180$ dpkg -l | grep libssl
ii libssl-dev 0.9.8g-15+lenny11
SSL development libraries, header files and
ii libssl0.9.8 0.9.8g-15+lenny11
SSL shared libraries

Mac: are you using a "ports" system?

Yes, openssl @1.0.0d (devel, security) is installed


I am beginning to suspect that ssl is not the problem. openssl and
libssl and libssl-dev is installed on all systems. There is no options
to select alternative paths to libssl in Ruby's configure script.
Digest::Base does not work with neither my compilations of ruby1.9.1 and
ruby1.9.2 OR with the precompiled Ruby1.9 Debian and Ubuntu packages.

( - what then?


Martin

 

[Phillip Gawlowski]

I dont really see anything:

http://pastie.org/1892928

--with-PACKAGE is the correct one, where "PACKAGE" should be replaced
with "openssl" (so, adding the path was incorrect information on my
part).

But /usr/lib is included per default, right?

It should, yes.

Crazy!

Kinda. In the Bad Old Days nobody wanted to hand strong cryptography
to the Soviets. The easiest way was classifying crypto as weapons,
instead of creating a new category (since weapons could be traded with
NATO partners, obviously).

We already tried this:

configure: WARNING: unrecognized options: --with-openssl

Same with and without a path, and same for --with-ssl.

Can we somehow test if Ruby has SSL support - without using digest -
which appears to be broken?

Sure. Try to access a website that uses HTTPS, like so:

Sure. Try to access a website that uses HTTPS, like so:

OK, so something ssl is probably fubar. It is strange that it appears to
be a problem with both the precompiled debian packages and my ruby
do-it-yourself compile.

Grrr. I need some systematic approach to track down this issue.

[brabuhr]

Digest::Base does not work with neither my compilations of ruby1.9.1 and
ruby1.9.2 OR with the precompiled Ruby1.9 Debian and Ubuntu packages.

Debian package: apt-get install libopenssl-ruby1.9

 

[brabuhr]

Debian package: apt-get install libopenssl-ruby1.9

(Though I thought this step was no longer necessary?)

What versions of debian/ubuntu/redhat?

You could also try RVM (after installing the -dev[el] packages).

 

[Martin Hansen]

Debian package: apt-get install libopenssl-ruby1.9

I tested with the precompiled libopenssl-ruby1.9.1 and the precompiled
ruby1.9.1 from Ubuntu. Still no Digest::Base.

Ubuntu 10.04.2 LTS

And my Mac -> snoleopard.

You could also try RVM (after installing the -dev[el] packages).

No idea what this does. I would like to simply compile my own ruby and
have it working.

https://rvm.beginrescueend.com/

It grabs source code for Ruby implementations, and compiles it.

I've used this link for installing RVM on Ubuntu, it's very well-written
and easy to follow.

I think, that I want to get my ruby working the "old fashioned" way
before going fancy.

ruby -rdigest -e "p Digest.const_defined? :Base" => true

I get false on three different systems. Just tested on my office mate's
mac where it returns 'true' (though ruby 1.8.7).

Could it be a problem with old libs sitting around?
