Hello Jorge,

You need to set your PYTHONPATH environment variable. Please have a look at the explanation in $SRCDIR/buildtools/autogen/ README

Regards,

Jennie

Hi Jan,

I made a checkout of the cvs modules and after compile buildtools successfully and when i tried to compile MonetDB:

[jmartin@outsourcing1 MonetDB]$ ./bootstrap automake 1.9.6 is 1.7 or newer. Good. autoconf 2.59 is 2.57 or newer. Good. libtool 1.5.22 is 1.4 or newer. Good. Python 2.4.3 is 2.0.0 or newer. Good. Traceback (most recent call last): File "/home/jmartin/monetdbcvs/bin/autogen.py", line 29, in ? from autogen import am ImportError: No module named autogen

please help.

Hi Jorge,

I just extended the implementation of fn:number to cope with NaN values in equality predicates.

In case you have trouble avoiding the restriction you can try out the CVS head version (-- the nightly build will be available tomorrow). To make use of my changes you have to activate the (not yet standard) algebra code generation (using '\G' in your mclient).

Thanks Jan,

I'll try to rewrite some parts of the xquery as you said.

best regards.

Hi Jorge,

we compile XQuery into relational algebra and afterwards into the MonetDB specific language MIL. The query plan (our correspondent for a stack trace) thus will not help you.

I would have suggested you a function like the following

declare function mynumber ($foo as xs:string*) as xs:double* { for $a in $foo return if ($a castable as xs:double) then number($a) else () };

but I just detected (to my astonishment) that we do not support the castable concept yet. The only solution I thus see is a filter that looks for strings starting with digits instead of checking for castable. (This is admittedly a very ugly adaption).

The other solution would be to look into the data and find a better filter based on path step predicates.

Thanks Jan,

but can a active some debug info or similar to print the stack trace when a runtime error is triggered?

i think it could be very usefull. ;)

thanks again.
