there is something funny about this plugin

 

1.

if I uncomment the //#ifdef PCRE_SUPPORT

even though I have PCRE compiled, but it always go under the #else statement ... dunno why

 

2.

and the only way to make this work porperly is also

uncomment the #ifdef PCRE_SUPPORT inside npc.h !!

maybe its my compiler problem ? microsoft visual basic 2010

Yeah, seems to be windows compiler problem.. This is what I'm experiencing with installing the server side manners plugin by odin..

 

When I tried to compile the same plugin with linux, it compiled properly but the plugin doesn't load ( but it seems to be the plugin source itself)...

I cant compile it

Hmm, did you run ./configure in linux, if  yes, did you see if pcre being said yes during the configuration..

 

Then, when it comes to plugins, i think you need to add this in the makefile when compiling pcre plugins,

 

 

../../plugins/pluginname@DLLEXT@: pluginname.c $(ALL_H)
@echo " CC $<"
@$(CC) -lpcre @DEFS@ @CFLAGS@ @CPPFLAGS@ @LDFLAGS@ @SOFLAGS@ -o $@ $<

[AnnieRuru 957]

so its not my compiler problem, many member else experiencing this issue

seems to me like the pcre are not compatible with plugins

 

@samuel

I'm using windows with microsoft visual express so

I also try fix odin server side manner

http://upaste.me/a7a2110923a939b03

and my compiler throw this error

2>whisp.obj : error LNK2019: unresolved external symbol __imp__pcre_exec referenced in function _filter_chat2>whisp.obj : error LNK2019: unresolved external symbol __imp__pcre_study referenced in function _read_manner2>whisp.obj : error LNK2019: unresolved external symbol __imp__pcre_compile referenced in function _read_manner2>whisp.obj : error LNK2001: unresolved external symbol __imp__pcre_free2>..pluginswhisp.dll : fatal error LNK1120: 4 unresolved externals

that is the reason I'm actually using libpcre->compile, libpcre->study and so on because it has already defined in npc_chat.c

https://github.com/HerculesWS/Hercules/blob/master/src/map/npc_chat.c#L436

 

that's why ...

 

@安赫尔

yes, like I said in my 2nd point

to make this plugin works,

comment the line inside npc.h

line 285, change #ifdef PCRE_SUPPORT into //#ifdef PCRE_SUPPORT

line 348, change #endif into //#endif

then this plugin will work

but doing like this will defeat the purpose of making a plugin, because plugin means you don't have to touch the source ?

 

the patch is actually working though

http://upaste.me/c4861109339c41185

but not the plugin ...

 

maybe I should do a pull request ...

[Samuel 83]

Well, this error LNK2019: unresolved external symbol also happens with some source I'm converting into plugin..

 

It's like that it was already defined in the included source, but plugins can't get it or something..

 

I remember that I tried to define the unresolved external symbol within the plugin code itself and the warning disappeared..

yeah ... yeah ... the error disappeared

but you also get the ShowError warning saying that it is disabled

[Samuel 83]

Well seems to be a limitation for the plugin system as of now..

 

Although I hope there would be great updates with it,

oh thanks for the yellbox ... I was just about to edit the title though

 

ok time to try out the command

prontera,159,183,5	script	pcre_match	1_F_MARIA,{	input .@t$;	if ( "([a-z])$" ~= .@t$ )		npctalk "It's a "+ $@regexmatch$[0];	close;L_1:	npctalk "It's a "+ $@p2$;	end;OnInit:	defpattern 1, "^[^:]+: (|d{2})?([a-z]).$", "L_1";	activatepset 1;	end;}prontera,155,183,5	script	regexp	1_F_MARIA,{	input .@t$;	if ( regexp("([a-z])$", .@t$ ) )		npctalk "It's a ... ";	close;}

Haru's regular expression ...

this is bug ... why that only accept a,z,- ... three characters only

 

regexp in this plugin is accurate, can accept anything between abcde...z

but cannot export the result set

the symbol for the end line, has to be $

 

defpattern ... works great as many members already using it

but the symbol for the end line, has to be .$

 

omg, so many patterns !
