From: Daniel Carrera >Date: Sun, 12 Jan 2003 04:30:03 +0900Hi Daniel,Ok, here’s some more info:>ruby -e ‘puts $LOAD_PATH’/boot/home/Programming/Ruby/Extensions/sys-uname-516>ruby -e ‘puts $LOAD_PATH’/boot/home/config/lib/ruby/site_ruby/1.8/boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/boot/home/config/lib/ruby/site_ruby/boot/home/config/lib/ruby/1.8/boot/home/config/lib/ruby/1.8/i586-beos.Looks alright.The extconf.rb for uname is simply (after I removed the solaris specific have_header):require 'mkmf’create_makefile(‘sys/uname’)Output of manually building uname in its own directory:/boot/home/Programming/Ruby/Extensions/sys-uname-538>makegcc -g -O2 -I. -I/boot/home/config/lib/ruby/1.8/i586-beos -I/boot/home/config/lib/ruby/1.8/i586-beos -I. -c uname.cld -shared -L/boot/develop/lib/x86 -lbe -lroot -L"/boot/home/config/lib" -o uname.so uname.o -lruby/boot/home/Programming/Ruby/Extensions/sys-uname-539>make installuname.so → /boot/home/config/lib/ruby/site_ruby/1.8/i

586-beos/sys/uname.sochmod 0755 /boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/sys/uname.soSeems to be in the load path. I also tried adding have_library(“be”), and have_library(“root”) just for kicks because I saw it during the ruby build process. No effect one way or the other (not that I really expected any). The result in every case:>ruby test.rb/boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/sys/uname.so: Failed to load /boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/sys/uname.so (LoadError)>Did you ./configure again after you made the changes? >Does the new directory contain extconf.rb?Yes to both. I also just tried make’ing without reconfiguring as well as moving the .so file into other directories within the $LOAD_PATH.Oh, btw, I don’t see a Test.c anywhere in the ruby source. Is this something you just made up? The file I used is sys-uname, available on ruby-sysutils.sourceforge.net if you want to look at it.Any other ideas?Regards,DanOT Stuff:>Cool.

Great to see another OS supported. I’ve heard good things of BeOS. >I hope it growsIt’s more or less dead, unfortunately. If you want to give it a shot, I suggest the “Developer’s Edition”, available on bebits.com. You can also check out the openbeos project at openbeos.org. It really is a good OS - I prefer it over Linux in many ways. Too bad MS effectively killed it.

Oh, btw, I don’t see a Test.c anywhere in the ruby source. Is this
something you just made up?

OOps, sorry. Test.c is what I called the very first example in PickAxe.
It seems like a good test because it’s just about the simplest extension
you can make. Take a look at it. You might want to try it.

Ok, here’s some more info:

ruby -e ‘puts $LOAD_PATH’
/boot/home/config/lib/ruby/site_ruby/1.8
/boot/home/config/lib/ruby/site_ruby/1.8/i586-beos
/boot/home/config/lib/ruby/site_ruby
/boot/home/config/lib/ruby/1.8
/boot/home/config/lib/ruby/1.8/i586-beos

I notice that ‘.’ is not present (but that doesn’t matter for this
particular case).

Output of manually building uname in its own directory:

Seems to be in the load path.

Yes it does. That’s odd. Try

$ ls /boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/sys

To verify it’s there. I’m sure it is.

You could cd to that directory and try :

ruby -e ‘require “uname”’

after adding ‘.’ to the LOAD_PATH. There’s an environment variable todo
this, but I forget what it is.

Try the example from PickAxe. I’ll get back to you if I think of
anything.

First off, my apologies for that last response. Apparently, Phoenix
for BeOS has some problems with newlines. I have no idea what
happened.

Oh, ok. Well, I didn’t try that but I did try a simpler version of
sys-host and even that failed.

Ok, here’s some more info:

ruby -e ‘puts $LOAD_PATH’
/boot/home/config/lib/ruby/site_ruby/1.8
/boot/home/config/lib/ruby/site_ruby/1.8/i586-beos
/boot/home/config/lib/ruby/site_ruby
/boot/home/config/lib/ruby/1.8
/boot/home/config/lib/ruby/1.8/i586-beos

Actually, it is. I think the format of my last post caused confusion.

$ ls /boot/home/config/lib/ruby/site_ruby/1.8/i586-beos/sys

To verify it’s there. I’m sure it is.

Yes, it’s definitely there. I don’t think it’s a problem of seeing it
(I’d get a “no such file” error in that case). It just doesn’t like
something about the shared object itself.

Any ld tips that might help?

Regards,

Dan
