FXRuby on Mandrake 8.2

Ludo · 25 November 2002 17:04

Hi, could someone help a beginner rubyer please ?

I’m trying to test FXRuby on Mandrake 8.2
I compile a fox library version 1.0.26 with no problem
Then compile the FXRuby-1.0.16 without problem
but when I try irb …

irb(main):001:0> require 'fox’
LoadError: /usr/lib/libcrypto.so.0: shared object not open -
/home/coquelle//lib/ruby/site_ruby/1.6/i686-linux/fox.so
from (irb):1:in `require’
from (irb):1

I’ve read some non soluced identical problem … and I don’t know what
to do now …
Anybody could advice please ???

LoadError: /usr/lib/libcrypto.so.0: shared object not open -
/home/coquelle//lib/ruby/site_ruby/1.6/i686-linux/fox.so

What give ldd for these libraries ?

This post:

http://www.ruby-talk.org/44338

suggests that you may be able to alter your LD_LIBRARY_PATH setting to
fix it.

Hope this helps,

all seems ok
and libcrypto.so.0 seems ok too !
really I don’t understand …
could it be a(nother) Mandrake problem ?

Well apparently the error message suggest that it has a problem with
libcrypto.so.0 but why ???

I have recompiled openssl (libcrypto is in it) but no change.
I do not understand the message “shared object not open” !!!

Try

export LD_DEBUG=symbols

Look for the last lookup before dl_signal_error

I don’t knew this possibility … and I have some difficulties to
understand all the messages that gives the linker … I will look more
in details later
(strange that I can’t pipe all the logs in a file by 'ruby test.rb 2>&1

lib_lookup.txt’ …)
but thanks a lot !

Is it possible that the FOX library (libFOX.so) and the FXRuby extension
(fox.so) were compiled with different versions of g++? I know that for
Red Hat 8.0 and Mandrake 9.0 they upgraded to g++ 3.2 as the default
compiler.

Yes, this was this.

Guy Decoux

Ludo · 26 November 2002 14:55

It was exactly my problem !

I had 2 libFOX.so, and the one dynamicaly loaded was compile with
gcc-2.96, wheras my lib FXRuby (fox.so) was compile with gcc-3.2 (even
if I have just Mandrake8.2)
so there was a problem of symbols (FXApp.metaClass from libFOX.so under
gcc-2.96 is named FXApp9metaCLassE under gcc-3.2) … but the error
message from the linker at execution time wasn’t really clear :)) seems
to be clearer under glibc-2.2.5 …

thanks a lot to every body who guided my research ! ;))
