XQilla-2.3.2 – Tooling up for 2016 (Part 2) (XQuery)

Filed under: Virtual Machines,XML,XQilla,XQuery — Patrick Durusau @ 5:03 pm

As I promised yesterday, a solution to the XQilla-2.3.2 installation problem!

Using a virtual machine to install the latest version of Ubuntu (15.10), which had the libraries required to install XQilla!

I use VirtualBox from Oracle but people also use VMware.

Virtual boxes come in all manner of configurations so you are likely to spend some time loading linux headers and the like to compile software.

The advantage of a virtual box is that I don’t have to risk doing something dumb or out of fatigue to my working setup. If I have to blow away the entire virtual machine, its takes only a few minutes to download another one.

Well, on any day other than New Year’s Day I found out today. I don’t know if people were streaming that many football games or streaming live “acts” of some sort but the Net was very slow today.

Introducing XQuery to humanists, librarians and reporters using a VM with the usual XQuery suspects pre-loaded would be very cool!

Great way to distribute xqueries* and shell scripts that run them for immediate results.

If you have any thoughts about what such a VM should contain, etc., drop me an email patrick@durusau.net or leave a comment. Thanks!

PS: XQueries returned approximately 26K “hits,” and xquerys returned approximately 1,700 “hits.” Usage favors the plural as “xqueries” so that is what I am following. At the first of a sentence, XQueries?

PPS: I could have written this without the woes of failed downloads, missing header files, etc. but I wanted to know for myself that Ubuntu (15.10) with all the appropriate header files would in fact compile XQilla-2.3.2.

You may need this line to get all the headers:

apt-get install dkms build-essential linux-headers-generic

Not to mention that I would update everything before trying to compile software. Hard to say how long your VM has been on the shelf.

XQilla-2.3.2 – Tooling up for 2016 (Part 1) (XQuery)

Filed under: XML,XQilla,XQuery — Patrick Durusau @ 8:38 pm

Along with other end of the year tasks, I’m installing several different XQuery tools. Not all tools support all extensions and so a variety of tools can be a useful thing.

The README for XQila-2.3.2 comes close to winning a prize for being terse:

1. Download a source distribution of Xerces-C 3.1.2

2. Build Xerces-C

cd xerces-c-3.1.2/
./configure
make

4. Build XQilla

cd xqilla/
./configure –with-xerces=`pwd`/../xerces-c-3.1.2/
make

A few notes that may help:

Obtain Xerces-c-3.1.2 homepage.

Xerces project homepage. Home of Apache Xerces C++, Apache Xerces2 Java, Apache Xerces Perl, and, Apache XML Commons.

On configuring the make file for XQilla:

./configure –with-xerces=`pwd`/../xerces-c-3.1.2/

the README is presuming you built xerces-c-3.1.2 in a sub-directory of the XQilla source. You could, just out of habit I built xerces-c-3.1.2 in a separate directory.

The configuration file for XQilla reads in part:

–with-xerces=DIR Path of Xerces. DIR=”/usr/local”

So you could build XQilla with an existing install of xerces-c-3.1.2 if you are so-minded. But if you are that far along, you don’t need these notes. 😉

Strictly for my system (your paths will be different), after building xerces-c-3.1.2, I changed directories to XQilla-2.3.2 and typed:

./configure --with-xerces=/home/patrick/working/xerces-c-3.1.2

No error messages so I am now back at the command prompt and enter make.

Welllll, that was supposed to work!

Here is the error I got:

libtool: link: g++ -O2 -ftemplate-depth-50 -o .libs/xqilla

To help you avoid surfing the web to track down this issue, realize that Ubuntu doesn’t use the latest releases. Of anything as far as I can tell.

The bottom line being that Ubuntu 14.04 doesn’t have libicuuc.so.55.

If I manually upgrade libraries, I might create an inconsistency package management tools can’t fix. 🙁 And break working tools. Bad joss!

Fear Not! There is a solution, which I will cover in my next XQilla-2.3.2 post!

PS: I didn’t get back to the sorting post in time to finish it today. Not to mention that I encountered another nasty list in Most Vulnerable Software of 2015! (Perils of Interpretation!, Advice for 2016).

I say “nasty,” you should see some of the lists you can find at Congress.gov. Valid XML I’ll concede but not as useful as they could be.

Improving online lists, combining them with other data, etc., are some of the things I want to cover this coming year.
