Forum: Ruby Problem building Ruby 1.9.3 patchlevel 385 under AIX 7.1

Hello World!

I am trying to build Ruby 1.9.3 patchlevel 385  under AIX 7.1. The
./configure phase goes OK. The make part did not go well and end up with
the errors listed below.
Any help will be really appreciated.

Probably there's nobody who dabbles with AIX. I myself know nothing
about it.

The only thing I see is that you are compiling over a previous
compilation - maybe you should start from a clean source. At this
point, you can experiment with 2.0:

http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p0.tar.gz

But if that error of yours pops up again, there is little I can
say. You may try asking in an AIX forum...

Have you considered using JRuby?

When I was working with AIX a year ago, that's what I did.  There is an
issue with the IBM version of Java not accepting a command line flag 
that
the script that invokes JRuby uses.  You can find it easily with a 
search.

It's not what I know that counts.
It's what I can remember in time to use.

This problem is probably better posed to ruby-core@ instead of here... 
but to start, let's look at your problem:

10003 % more ext/-test-/load/dot.dot/dot.dot.c
void Init_dot(void) {}

Nothing really in there BUT the one function you're having problems 
with.

10004 % nm ext/-test-/load/dot.dot/dot.dot.o
0000000000000ef0 s EH_frame1
0000000000000000 T _Init_dot
0000000000000f08 S _Init_dot.eh

10013 % nm .ext/*/-test-/load/dot.dot/dot.dot.*
0000000000000f60 T _Init_dot
                 U dyld_stub_binder

You can see the T entry for _Init_dot. I'm guessing you have that. Why 
you're trying to pick up Init_dot.dot instead of Init_dot is strange and 
points at the loader not assembling the right name to begin with. I'm 
not familiar with that code and someone else on ruby-core@ will have to 
help. Please provide your equivalents to my commands above when you mail 
them. You can also use http://bugs.ruby-lang.org/ to file the ticket 
directly.

That's because the configure script set "DLDFLAGS='-eInit_$(TARGET)'" on 
AIX
and mkmf.rb creates Makefile which contains "TARGET = dot.dot".

IMO, one line in configure.in should be changed as follows:

        [aix*], [  : ${LDSHARED='$(CC)'}
      LDSHARED="$LDSHARED ${linker_flag}-G"
      DLDFLAGS='-e$(ENTRY_POINT)'        # CHANGE THIS LINE
      XLDFLAGS="${linker_flag}"'-bE:$(ARCHFILE)'" ${linker_flag}-brtl"

and two lines in lib/mkmf.rb  should be added as follows:

  dllib = target ? "$(TARGET).#{CONFIG['DLEXT']}" : ""
  entry_point = target ? "Init_#{target}".sub(/\..*\z/,'')  : "" # ADD
THIS LINE (1)
  staticlib = target ? "$(TARGET).#$LIBEXT" : ""

....

TARGET = #{target}
DLLIB = #{dllib}
ENTRY_POINT = #{entry_point}  # ADD THIS LINE (2)
EXTSTATIC = #{$static || ""}
STATIC_LIB = #{staticlib unless $static.nil?}

I have not tested this because I don't have AIX.

can you provide that in unified diff format so we can more cleanly apply 
it?

I found that it had already fixed in ruby 2.0.0.
  http://bugs.ruby-lang.org/projects/ruby-trunk/repo...
  http://bugs.ruby-lang.org/projects/ruby-trunk/repo...
  http://bugs.ruby-lang.org/projects/ruby-trunk/repo...
Backporting them to ruby_1_9_3 branch will be better than applying my 
change.

OK. I made the suggested changes and I got the following errors. Please
note that I am displaying only the last few records:
