[help-GIFT] configuration option and gift-generate-inverted-file errors

[Xin ZHOU]

hello,

i'm new user of gift so i was broken by some beginning problems. So i 
need some help.

version used gift-0.1.14

1st question:
to install gift other than the default directory, i use the option 
"--prefix". But it seems that those script use still the /usr/bin/. one 
exemple, i use ./configure --prefix /home/---/gift-local, but in 
gift-add-collection.pl i find something like :
=============================================================================
system("/usr/bin/gift-extract-features $lTemp");

system qq(/usr/bin/gift-write-feature-descs < $lTemp |perl -e 'print 
"Writing InvertedFileFeatureDescription...\n";open 
OF,">$main::lIndexPrefix/InvertedFileFeatureDescription.db" or die 
"could not open $lIndexPrefix";while(<STDIN>){print OF join(" ",(split(" 
",\$_))[0..1]),"\\n";};print "finished.\n";' );

system("/usr/bin/gift-generate-inverted-file $lIndexPrefix/");
============================================================================
so when i use gift-add-collection.pl, very evident that 
gift-extract-features hadn't been excuted.

i'm afraid that somewhere else in the program, i've still this type of 
problem. so what i want to know is that :

1. if i use a correct version ?? if not, which one should be?? where can 
i get it??

2. if it's a correct version, then this means that the configure option 
which i use is wrong. So what does the correct one look like?? Or should 
i put some other option??

3. if it's a correct version and the configure option which i use is 
right, then, does it means that we should do something manully? like 
type "gift-generate-inverted-file /gift-index-data/collection-name/"?? 
Was it  all i should do?? or is there any other changement which hadn't 
been detected??

*************************************************************************************

second qestion for " gift-generate-inverted-file ". As i mentioned, when 
i finish gift-add-collection.pl, the gift-generate-inverted-file hadn't 
been excuted. So i've got url2fts.xml, InvertFileFeatureDescription.db, 
gift-auxiliary-1, gift-auxiliary-2, these 4 files are not in size 0. 
InvertedFile.db and InvertedFileOffset.db are in size 0. So i suggest 
that i should run myshelf " gift-generate-inverted-file ". So the output 
message is this :

==============================================================================
i look into the code of "merge_sort_streams.h", however i've no idea 
where is the problem.... I've checked the gift-config.mrml, the 
collection-ID, collection-name are all correct. So i'm lost.

waiting for your help. thx very much
