I’ve switched to Nokogiri, it’s more robust and easier to install:

Correction to the comment above:

1) gem install hpricot
2) cd $GEM_SOURCE (see from error message above)
3) cd ext/hpricot_scan
4) sed -i ’s,#include ,#include “ruby_macros.h”,g’ *.h *.c *.rl
5) vi ruby_macros.h
#ifndef __RUBY_MACROS__
#define __RUBY_MACROS__

#include

#ifndef RARRAYPTR
# define RARRAYPTR(v) RARRAY(v)->ptr
#endif

#ifndef RARRAY_PTR
# define RARRAY_PTR(v) RARRAY(v)->ptr
#endif

#ifndef RSTRUCT_PTR
# define RSTRUCT_PTR(v) RSTRUCT(v)->ptr
#endif

#endif
(include “lower-than”ruby.h”greater-than”… dunno if the braces/brackets whatever appear in the comment)
6) cd $GEM_SOURCE (see above)
7) rake install
rake install (still 2 times necessary)

that’s it.

Hi,
for me it worked after manual installation of ragel (source code) and changing the ruby_macros.h to

#ifndef __RUBY_MACROS__
#define __RUBY_MACROS__

#include

#ifndef RARRAYPTR
# define RARRAYPTR(v) RARRAY(v)->ptr
#endif

#ifndef RARRAY_PTR
# define RARRAY_PTR(v) RARRAY(v)->ptr
#endif

#ifndef RSTRUCT_PTR
# define RSTRUCT_PTR(v) RSTRUCT(v)->ptr
#endif

#endif

After this I did the sed from above and performed a
ruby setup.rg in the gem-root. Did this again and then 2 times a “rake install” in the gem-root.

Strangely it did not work the 1st time therefore I repeated both “installs”

Thanks for your efforts!

CentOS release 4.3 (Final), ruby 1.8.7 (Source)

sudo apt-get install ruby1.8-dev

worked for me.

Actually, scratch that; it _installed_ successfully, but once I tried to execute Hpricot code in irb, it bailed with an “undefined symbol: RSTRING_PTR” error.

So, I started my Ruby install from scratch, building 1.8.6 from source rather than sticking with the 1.8.4 apt-get offered… A few headaches later, everything works!

Thanks for this! I was able to fix a very similar problem. In my case I was getting:

hpricot_scan.rl:181: warning: implicit declaration of function ‘RSTRUCT_PTR’

…followed by a flood of “subscripted value is neither array nor pointer” errors. So in my ruby_macros.h file, I put:

#ifndef RSTRUCT_PTR
# define RSTRUCT_PTR(v) RSTRUCT(v)->ptr
#endif

And it worked!

(I also had to install Ragel 6.5 from source as apt-get in Ubuntu Dapper would only install 5.1. This is w/ Ruby 1.8.4, RubyGems 1.3.5, and Hpricot 0.8.1.)

Same comment (and same configuration) as Jed about RARRAY_PTR instead of RARRAYPTR.

Just change ruby_macros.h to:

#ifndef __RUBY_MACROS__
#define __RUBY_MACROS__

#include

#ifndef RARRAY_PTR
# define RARRAY_PTR(v) RARRAY(v)->ptr
#endif
#endif
