Has anyone successfully compiled Ruby on HP-UX?

[Ralph Grothe]

I wish to get Ruby on HP-UX.
I searched at software.hp.com but got no hit.
The version packaged on HP Porters is a bit dated, and since it relies on many libs (like openssl) which probably are 32Bit gcc compiles it won't link with HP's OpenSSL depot.
So I currently try to make it on B.11.11 with ansic, but as usual, got choked at openssl parts.
As I wish to use Rails or other web modules I hardly can do without OpenSSL for I need to run SSL connections as well.

I had a look at the very terse README from the ruby tarball and ran configure --help, to be very surprised how few fiddle switches were proposed unlike with Perl builds.
So I merely invoked configure like this to point to HP's openssl install target:

LDDFLAGS="-L/opt/openssl" CPPFLAGS="-I/opt/openssl/include/openssl" ./configure

A make aborts at this point when compiling
ossl_config.c:

/opt/ansic/bin/cc -I. -I../.. -I../../. -I../.././ext/openssl -DRUBY_EXTCONF_H=\"extconf.h\" -I/opt/openssl/include/openssl +Z -g -c ossl_config.c

You might want to show the lines with the above errors so we can give you a hint what should be done to correct them.

C89 doesn't allow you to initialize locals with non-constants, within {}.

[Ralph Grothe]

Hi Dennis,

you're probably right.
This is the offending block with a maybe past C89 liberal array declaration in line 248?

245 static VALUE
246 ossl_config_set_section(VALUE self, VALUE section, VALUE hash)
247 {
248 VALUE arg[2] = { self, section };
249 rb_iterate(rb_each, hash, set_conf_section_i, (VALUE)arg);
250 return hash;
251 }

>This is the offending block with a maybe past C89 liberal array declaration in line 248?

Right. This is legal C99 or C++ but not C89.
Just change it into two assignments to the array elements.

I'm not sure what the array cast to array element is suppose to do on 249:
(VALUE)arg

It would be valid if VALUE was void*.

[Luk Vandenbussche]

Here you find the binaries

http://hpux.connect.org.uk/hppd/hpux/Shells/ruby-1.8.4/

[Ralph Grothe]

You mean like so?

246 ossl_config_set_section(VALUE self, VALUE section, VALUE hash)
247 {
248 VALUE arg[2];
249 arg = { self, section };
250 rb_iterate(rb_each, hash, set_conf_section_i, (VALUE)arg);
251 return hash;
252 }



I'm also puzzled by the typecast to VALUE of the last param in the rb_iterate call.
Alas, I'm no C hacker.

[Dennis Handly]

No, like:
248 VALUE arg[2];
249 arg[0] = self;
250 arg[1] = section;

>I'm also puzzled by the typecast to VALUE of the last parm in the rb_iterate call.

Well, no C warning so it must not be too bad.

[Ralph Grothe]

Nope, I think I need to lookup C basics,
how to assign array elems ;-)

cc: "ossl_config.c", line 249: error 1000: Unexpected symbol: "{".
cc: "ossl_config.c", line 249: error 1000: Unexpected symbol: "}".
cc: "ossl_config.c", line 249: error 1549: Modifiable lvalue required for assignment operator.


I bet this is fool proof though awkward?

arg[0] = self;
arg[1] = section;

[Ralph Grothe]

Wow, single elem assignment worked :-)
Now make is progressing...
And even finished without errors and zero exit code.

Many thanks for your instant help.
You saved my day.

Just out of curiosity,
does C89 allow multiple array elem assignment with curly braces at all?

[Ralph Grothe]

Such a silly nonenty, such an effect.

[Ralph Grothe]

Luk,

I had seen these builds already
but I didn't want to use them for the above mentioned reasons.

[Dennis Handly]

>does C89 allow multiple array elem assignment with curly braces at all?

Sure but they all must be constant expressions.

[Ralph Grothe]

Ah yes, you were already mentioning this.
Well, I would have considered compound array initialization by already previously declared variables quite common fare these days.
But then I may have been spoiled by non typed languages.

[Dennis Handly]

>I would have considered compound array initialization by already previously declared variables quite common fare these days.

It is legal in real languages like C++ and and for auto variables in C99. ;-)
I'm not sure if your PA C compiler will take it if you add -AC99?

Hello,

To build Ruby 1.8.7 or 1.9.2 on HP-UX IA64 B.11.31 (not tested on other versions), see http://vouters.dyndns.org/tima/HP-UX-Installing_Ruby_On_Itanium.html

Yours truly,

Congratulation, you answered a Thread from 2007 ;-)

And to add something useful, alternative would be using Internet Express for it.
