I am having some trouble with building.

1. I have two libiconvs installed, one supplied with my OS in  
/usr and another in /opt/local. Using  
–with-iconv-dir=/opt/local fails to locate libiconv, but  
–with-iconv-dir=/usr works. I made a change to extconf.rb:

## $ diff libxml-ruby-0.3.6.orig/ext/xml/extconf.rb libxml-ruby-0.3.6/ ext/xml/extconf.rb 45,46c45,49 \< unless have\_library(‘iconv’,‘iconv\_open’) or have\_library (‘c’,‘iconv\_open’) or \< have\_library(‘recode’,‘iconv\_open’)

> unless have\_library(‘iconv’) or  
> have\_library(‘iconv’,‘iconv\_open’) or  
> have\_library(‘c’,‘iconv\_open’) or  
> have\_library(‘recode’,‘iconv\_open’)

```
and --with-iconv-dir=/opt/local worked.

```

1. You call two shell commands, xml2-config and xslt-config. I  
have two versions of libxml2 and libxslt installed, so this  
command is dependent on the correct command being in my PATH  
before the other one. I am not sure what to do about this  
problem.

What is the difference between this and xml-smart. It looks like  
xml-smart  
has bindings for libxml also.

We’re working separately on bringing the libxslt bindings up to date in  
the same way. We decided to concentrate on a first libxml release before  
moving on to that.

I’m hoping to get baseline code into CVS this week, with a release to  
follow ASAP.

I’m not sure about this - I’m still finding my way around some things  
here, but I’m pretty sure we do need iconv\_open(3) in libiconv. Does it  
compile with this change?

I’m going to forward this as a possible change to the mailing list at  
removed\_email\_address@domain.invalid .

If you are passing --with-xml2- settings, you should be fine  
to comment-out the lines that run those scripts (for both CFLAGS and  
LDFLAGS). If that works for you I’ll fix it with a default to the  
dir\_config and commit it.

(I’m still finding new stuff in mkmf so if I’m missing anything, please  
let me know :))

The problem is really strange. I have libiconv-1.9 installed in  
/usr, and libiconv-1.10 installed in /opt/local. mkmf says  
iconv\_open(3) isn’t available in v1.10, but it is. Have you  
tested with libiconv-1.10? Was there ever a libiconv that did not  
have iconv\_open()?

I did this, and all unittests passed.

Hmm. The website lists 1.9.1 as the latest stable release. I need to  
look more into this I think, but one thing you might try is specifying  
–with-iconv-lib and --with-iconv-include separately, rather than  
–with-iconv-dir.

Thanks, I’ll commit that fix tomorrow.

In all honesty, I’ve no idea. A quick glance suggests some differences  
in API, I think this is a slightly thinner layer on top of LibXML2 but  
then I could be entirely wrong…

I should mention that I’m just helping to maintain this code, it’s been  
around for some time…

I tried this too, it did not work.

There is small documentation error at  
[http://libxml.rubyforge.org/doc/classes/XML/Dtd.html](http://libxml.rubyforge.org/doc/classes/XML/Dtd.html)

The class is named Dtd, but DTD is used. Also, the name of two classes,  
Dtd and SaxParser, is inconsistent with the naming conventions of the  
library – it should be DTD and SAXParser.
