I am using erlang 18, ejabberd 15.09. I am trying to create chat application. For that I have to create user for ejabberd using Erlang.
I used the erlang function ejabberd_auth:try_register for that:
ejabberd_auth:try_register(<<"username">>, <<"example.com">>, <<"secret_password">>).
It produced the following error：
exception error: undefined function stringprep:nameprep/1
in function jlib:nameprep/1 (src/jlib.erl, line 331)
in call from ejabberd_auth:auth_modules/1 (src/ejabberd_auth.erl, line 429)
in call from ejabberd_auth:is_user_exists/2 (src/ejabberd_auth.erl, line 323)
in call from ejabberd_auth:try_register/3 (src/ejabberd_auth.erl, line 187)
How to resolve the issue？
You do not seem to have the stringprep dependency installed. the p1_stringprep (https://github.com/processone/stringprep) dependency is downloaded automatically during build or included in official packages.
Your error suggest an incorrectly build or incorrectly installed ejabberd.

I have reinstalled #nestjs/swagger and swagger-ui-express. All my dependencies are up to date. But I get this error:
applicationConfig.getVersioning is not a function at SwaggerExplorer.exploreRoutePathAndMethod
I have updated metadata tags in tsconfig.ts file as well. After debugging, I can find that the main issue is at line where createDocument function is called from Swagger Module class. Every code line before that works fine.
On console logging, I even could extract the values of config-correctly. However, once the createDocument method is called, the API comes to a crashing halt with the above stated error.
/home/prasanna/my_project/TapisProject/API/API/node_modules/#nestjs/swagger/dist/swagger-explorer.js:125
const controllerVersion = this.getVersionMetadata(metatype, applicationConfig.getVersioning());

need to upgrade #nestjs/core as well –
This question is with reference to the question in the link:
"** exception error: undefined function add:addfunc/0 in Erlang "
I'm trying to execute a simple erlang program of adding two numbers. I'm trying to do this in Eclipse on Ubuntu 10.04 LTS.
When I execute this program, I'm getting the error as shown below:
-module(add).
-export([addfunc/0]).
addfunc() ->
6 + 5.
" ** exception error: undefined function add:addfunc/0 "
This program when executed in the erlang shell is working fine. But when it comes to eclipse it's giving me this error. Not this, any program for that matter is giving me the similar error. Guess I would be missing something about the eclipse configuration.
I haven't tested your code, but this very basic code should work.
The message says that your function does not exist.
Make sure that you have no errors at compile time.
Check whether your function is exported with:
add:module_info().
the result should look alike this:
[{module,add},
{exports,[{addfunc,0},

I had built lua 5.1.5 and lsqlite3-0.8.1. all of them run well on my RedHat Linux.
and then I ported them to my MIPS development board. lua and other modules (such as luafilesystem, md5, cgilua and wsapi) run well. but lsqlite3 does not work.
when I execute require("lsqlite3") in lua command line, it returns error messages in below:
lua
Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio
require("lsqlite3")
do_page_fault() #2: sending SIGSEGV to lua for invalid read access from
00000000 (epc == 00000000, ra == 2ac36144)
Segmentation fault
can any one give me any help to fix it? Thanks!
I got few progress in solving this problem, I rebuilt the LUA with gcc compile option '-Wl,-E' and rebuilt lsqlite3 later. I executed require ("lsqlite3") in lua command line, and it didnt print any message. I continued running some other database operation commands and found them all been successfully executed. As it seemed the problem had been solved, I should be very happy about it.
but another more strange problem raised.
If I put sentence require("lsqlite3") into a file, and then execute the file in this way:
lua file
it still printed error messages like this:
do_page_fault() #2: sending SIGSEGV to lua for invalid read access from
2ada054c (epc == 2ada054c, ra == 2abdceac)
If I put more database operation sentences into a file, and then run this file by lua. Lua can give correct result of query operation and insert values to table correctly, but always print error messages showed above.
If I run sentences in the file one by one in lua command line interface, it never print this error message.
It seems to give the error message when executing the 'require' function. But if I put require("lfs") into a file and run this file by lua, it never print error message.
I am confused that whait is the difference between the lua command line execution and lua script.
There are three places in lsqlite3.c where sqlite_int64 is used (never long long directly). When you build sqlite3 some type will be used for 64 bit integers; lsqlite3 will use the same type by including sqlite3.h for the definition of the type.
I'm putting together an application that uses the moon soap, but when you run it reports the following error :
C:\Lua\5.1\lua.exe: error loading module 'lxp' from file 'C:\Lua\5.1\clibs\lxp.dll':
The specified module could not be found.
How do I fix this ?
This is not a "file not found" error. Note that the message stated that it tried to load the module "lxp" from a file ('C:\Lua\5.1\clibs\lxp.dll') but it didn't work. Maybe the file doesn't have a luaopen_lxp C function (which might be called by loadlib)... Or maybe you are not loading it with require...
I am trying to use the Erlang ddb module to interface with amazon's DynamoDB and I am getting a strange error while trying to set things up. I call ddb_iam:credentials() and it returns 'ok', but the ddb_iam:token() function crashes with an error as such: (this example is taken right from the manual page.
ddb_iam:credentials(AccessKey, SecretKey).
{ok, Key, Secret, Token} = ddb_iam:token(129600).

It sounds like ibrowse is not started:
ibrowse:start().
