i,

I've been compiling Math::GMP for different OS's in order to use

Net::SFTP and I have successfully compiled and used it for Solaris,

HP-UX.11 and Linux, but I'm running into trouble on Compaq (Tru5.1b).

GMP library compiled without trouble and all tests were passed. I'm

trying to make a dynamic and only OS dependant version of Math::GMP

(and of Net::SFTP) and thus GMP was configured as follows: (hardware

model from config.guess)

./configure --prefix=$(INSTALL_DIR)/GMP --disable-static

--build=alphaev6-dec-osf5.1 --host=none-unknown-osf5.1

Now the next step was to compile Math::GMP and here are the failed

test results:

I am out of ideas what to try next.

I tried to ignore this and continued to compile my Net::SFTP but ran

into problems with Crypt::Random. The Crypt::Random tests fail due to

invalid arguments passed to divll.

Can anyone say whether this problem is related to the Math::Pari ie.

is Crypt::Random using Math::Pari incorrectly or what? Also

Crypt::Random tests take forever (1/2-2 hours) to execute. I haven't

experienced this kind of slowness on any other platform.

I'm using Perl 5.8.0 and it says:

Summary of my perl5 (revision 5.0 version 8 subversion 0)

configuration:

Platform:

osname=dec_osf, osvers=5.1, archname=OSF1alpha-dec_osf

uname='osf1 sinika

The GMP documentation suggests that those tests will fail if your

'unsigned long' and 'signed long' are not 32 bits. Your 'perl -V' (which

you thoughtfully provided) would suggest that your 'unsigned long' and

'signed long' are 64 bits. That being the case, the tests have returned

the values that are to be expected - ie they have passed, not failed.

The functions that reported a failure are 'uintify_gmp' and

'intify_gmp'. If you want to know what these functions do, go to:

http://www.yqcomputer.com/ #Converting%20Integers

and read the documentation on 'mpz_get_ui()' and 'mpz_get_si()'.

('uintify_gmp' is simply the perl interface to the former, and

'intify_gmp' the perl interface to the latter.)

As for the rest, I can't really help - though I'd be wondering how those

other modules also cope with 64 bit ints.

Cheers,

Rob

That's possibly a bit misleading. Just to make sure I'm being clear, the

tests *haven't* failed. A failure is being reported because the

"expected values" that the Math::GMP author provided are incorrect in

your case. (He assumed the tests were going to be conducted on a 32 bit

machine.)

Cheers,

Rob

So basicly everything _should_ be okay? The results returned from

Math::GMP are _correct_ and can not cause errors in future use?

Can this be considered as a bug in the Math::GMP test suite? I'd hate

to install this and later on find out that it does not work correctly.

anyway, thanks for the information :-)

ps. just for the record, this module is a prerequisite for Net::SSH

and thus for Net::SFTP which is my actual target. I don't know the

extent of GMP library usage so with a bit of luck this could be

ignored.

Sure can.

For these tests you really need to know whether it's 32 or 64 bit

architecture before you can work out what the expected return value is.

(The author has simply assumed that it's 32 bit architecture.)

Wouldn't be hard to find out which Math::GMP functions are used. Just

look for any imported functions when the module is loaded in these other

modules - also search them for the string 'Math::GMP::'.

However, at this stage I haven't seen anything which suggests to me that

you're going to strike trouble with *any* of the Math::GMP functions.

Cheers,

Rob
