Ruby load problem on AIX

ruby-talk
1

Hi,
   I have built Ruby 1.8.5 on an AIX 5.2 64 bit machine. I am using
xlc with OBJECT_MODE=64. When I try to run the following:

$ gem install rails --include-dependencies
/fasthome/fast3/manas/ruby185/lib/ruby/1.8/powerpc-aix5.3.0.0/
socket.so: load failed - /fasthome/fast3/manas/ruby185/lib/ruby/1.8/
powerpc-aix5.3.0.0/socket.so Not enough spac (LoadError)
        from /fasthome/fast3/manas/ruby185/lib/ruby/1.8/net/
protocol.rb:21

Any help or tips is appreciated.

Thanks in advance.

Regards,
-MD

Hi,

Have you resolved this issue?
I tried to investigate why load() failed, but I was not able to figure out.

Attached patch is to change dln.c behavior not to use load() but dlopen()
for AIX. This seemed to work in my environment.

% oslevel -s
5300-05-06

% ~/r185-64/bin/ruby -v -rsocket -e 'p IPSocket.getaddress("www.ruby-lang.org")'
ruby 1.8.5 (2006-08-25) [powerpc-aix5.3.0.0]
"221.186.184.68"

% ~/r185-64/bin/ruby -e 'p 0xffffffff.class'
Fixnum

If you have any other solution, let me know.

I eventually found this thread.

- DLDFLAGS='-Wl,-G -eInit_$(TARGET)'
- LDFLAGS='-Wl,-brtl -Wl,-bE:ruby.imp'
+ DLDFLAGS="${DLDFLAGS} -Wl,-G -Wl,-bnoentry -Wl,-bexpall"
+ LDFLAGS="${LDFLAGS} -Wl,-brtl -Wl,-bE:ruby.imp"

I don't know about -bnoentry and -bexpall options, are they
preferable?

-#if defined(_AIX) && ! defined(_IA64)
-static void
-aix_loaderror(const char *pathname)

Do all AIX versions support dlopen()? If not, these probably
should not be removed but be changed the condition.

Hi,

Thank you very much for catching this thread.

preferable?

To follow existing code which uses dlopen(), I omitted -e option.
Then, these options are used to supress some error message.

Do all AIX versions support dlopen()? If not, these probably

I have AIX 4.3.3 machine which is oldest in my test environment,
and it actually has dlopen(), but I think the older version AIX
would not have dlopen() (or broken?). I had prioritized the current
supported versions as matz said ( see [ruby-dev:29154]). I should
have been more carefully to support old versions.

Please give me some time to make another patch? I have noticed
the linker_flag variable you made. I will make new patch against
ruby_1_8 branch or trunk. Since I will test on various AIX versions,
it will take a little...

Thanks and best regards,
