David,
you need http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/tsearch_snowball_82.gz -
patch for 8.2 release, which updates snowball API.
You need it only for the new stemmers from sbowball site !
I'm not sure if it will apply for 8.1.8.

Hi everyone!!
I have an implementation of tsearch2 with spanish stemmers. I
updated
postgres to 8.1.8 version and I was going to reinstall the
tsearch2
contrib, everything was fine until I try to compile the spanish
stemmers
with gendict
$ ./config.sh -n sp -s -p spanish_ISO_8859_1 -v -C'Snowball
stemmer for
Spanish'
Dictname: 'sp'
Snowball stemmer: yes
Has init method: yes
Function prefix: spanish_ISO_8859_1
Source files: stem.c
Header files: stem.h
Object files: stem.o dict_snowball.o
Comment: 'Snowball stemmer for Spanish'
Directory: ../../dict_sp
Build directory... ok
Build Makefile... ok
Build dict_sp.sql.in... ok
Copy source and header files... ok
Build sub-include header... ok
Build Snowball stemmer... ok
Build README.sp... ok
All is done
after I get this error:
stem.c: En la funci?n 'spanish_ISO_8859_1_close_env':
stem.c:1092: error: demasiados argumentos para la funci?n
'SN_close_env'
make: *** [stem.o] Error 1
error: too many arguments to function 'SN_close_env'
So I search this error on the list and I see some posts related.
One of this posts says that I have to patch to get an updated
snowball
API. I download the patch from:
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/gin_tsearch2_81.gz
and I apply the patch this way
$ cd PG_SRC/
$ patch -b -p0 < gin_tsearch2_81
Everything going fine and recompile tsearch2
So I try to compile the stemmer again
$ ./config.sh -n sp -s -p spanish_ISO_8859_1 -v -C'Snowball
stemmer for
Spanish'
$ cd ../../dict_sp
$ make
stem.c: En la funci?n 'spanish_ISO_8859_1_close_env':
stem.c:1092: error: demasiados argumentos para la funci?n
'SN_close_env'
make: *** [stem.o] Error 1
And again I have the same error: too many arguments.....
So my question is why after I apply the patch I have the same
error?
What did I do wrong?
I take some paths to solve this issue I post here which finally
works
for me:
1.- Download Postgresql-8.1.8 sources
2.- Download the C implementation of snowball
http://snowball.tartarus.org/dist/libstemmer_c.tgz
3.- Download the patch to update Snowball API
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/gin_tsearch2_81.gz
4.- Unpack postgresql sources
5.- Unpack Snowball C
6.- Unpack the patch
7.- Apply patch with:
$ cp gin_tsearch2_81 PG_SRC/
$ cd PG_SRC
$ patch -b -p0 < gin_tsearch2_81
8.- Do configure
$ ./configure
9.- Copy the Snowball API to Tsearch2 dir
$ cp libstemmer_c/runtime/*
PG_SRC/contrib/tsearch2/snowball/
10.- Copy english and russian stemmers
$ cp stem_ISO_8859_1_english.c
PG_SRC/contrib/tsearch2/snowball/english_stem.c
$ cp stem_ISO_8859_1_english.h
PG_SRC/contrib/tsearch2/snowball/english_stem.h
$ cp stem_KOI8_R_russian.c
PG_SRC/contrib/tsearch2/snowball/russian_stem.c
$ cp stem_KOI8_R_russian.h
PG_SRC/contrib/tsearch2/snowball/russian_stem.h
$ cp stem_UTF_8_russian.h
PG_SRC/contrib/tsearch2/snowball/russian_stem_UTF8.h
$ cp stem_UTF_8_russian.c
PG_SRC/contrib/tsearch2/snowball/russian_stem_UTF8.c
11.- Change in english_stem.c, russian_stem.c,
rusian_stem_UTF8.c the
line with:
#include "../untime/header.h"
to:
#include "header.h"
12.- Compile tsearch2
$ make
$ make install
13.- Copy spanish stemmer
$ cp libstemmer_c/src_c/stem_ISO_8859_1_spanish.c
PG_SRC/contrib/tsearch2/gendict/stem.c
$ cp libstemmer_c/src_c/stem_ISO_8859_1_spanish.h
PG_SRC/contrib/tsearch2/gendict/stem.h
14.- Go to gendict directory and do the same sustitution in step
11 with
stem.c file
15.- Do:
$ ./config.sh -n sp -s -p spanish_ISO_8859_1 -v -C'Snowball
stemmer
for Spanish'
16.- Go to ../../dict_sp and compile
$ make
And have no errors finally this works, I have many doubts
related with
this way of add tsearch2 and snowball spanish like:
Is safe to add this to a DB in production?
This compilation it's "fine" I mean it's correct?
I will have some issues when I put this to work?
I know this is dificult to say but I ask you because you have
more
experience with this
Cheers mates!!
BTW I hope this mini HOW_TO helps others
