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've been attempting to import some wikipedia templates in my local mediawiki wiki, but most attempts at using them end up with the same error. For instance, for the following code :
==Title==
{{Main|Title}}
(which uses the main template), I get the following error :
Lua error: Internal error: The interpreter has terminated with signal "-129".
No further details are available.
I haven't been able to find any occurence of that error, or even a relevant use of 129 in the source code I could find, and there is nothing generated in the Lua error log.
The Lua binaries have all been given permission to be executed, and I have installed the Scribunto and TemplateStyles extensions and a variety of modules, although beyond the ones advised for main, I don't know where to find a list of missing modules if there are any.
Edit : Here is the output of $status in Scribunto :
array(8) {
["command"]=> string(459) "'exec' '/bin/sh' '/XXX/extensions/Scribunto/includes/engines/LuaStandalone/lua_ulimit.sh' '7' '8' '51200' ''\''/XXX/extensions/Scribunto/includes/engines/LuaStandalone/binaries/lua5_1_5_linux_32_generic/lua'\'' '\''/XXX/extensions/Scribunto/includes/engines/LuaStandalone/mw_main.lua'\'' '\''/XXX/extensions/Scribunto/includes'\'' '\''0'\'' '\''4'\'''"

["signaled"]=> bool(true)
["stopped"]=> bool(false)
["exitcode"]=> int(-1)
["termsig"]=> int(-129)
["stopsig"]=> int(0)
}
I am beginning to suspect that the issue may be that my server doesn't allow executables.
I want to run a (python3) process from my (yap) prolog script and read its output formatted as a list of integers, e.g. [1,2,3,4,5,6].
This is what I do:
process_create(path(python3),
['my_script.py', MyParam],
[stdout(pipe(Out))]),
read(Out, OutputList),
close(Out).
However, it fails at read/2 predicate with the error:
PL_unify_term: PL_int64 not supported
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='UTF-8'>
BrokenPipeError: [Errno 32] Broken pipe
I am sure that I can run the process correctly because with [stdout(std)] parameter given to process_create the program outputs [1,2,3,4,5,6] as expected.
Weird thing is that when I change the process to output some constant term (as constant_term) it still gives the same PL_int64 error. Appending a dot to the process' output ([1,2,3,4,5,6].) doesn't solve the error. Using read_term/3 gives the same error. read_string/3 is undefined in YAP-Prolog.
How can I solve this problem?
After asking at the yap-users mailing list I got the solution.
Re-compiled YAP Prolog 6.2.2 with libGMP option and now it works. It may also occur in 32-bit YAP.
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 tried building the first example here and got errors. Right on the first line there's a missing include statement, but I managed to figure out it should be
#include "hdf5.h"
But even after fixing that I got more errors:
$ h5cc ./example1.c
./example1.c: In function ‘main’:
./example1.c:66:4: error: too few arguments to function ‘H5Dcreate2’
In file included from /usr/include/hdf5.h:27:0,
from ./example1.c:6:
/usr/include/H5Dpublic.h:104:14: note: declared here
Any idea how to solve it?
The example code was written for release 1.6 of hdf5, and as such will simply not compile on a 1.8 release without modification.
If you want to get the code to work on 1.8, you need to enable 1.6 compatibility, which means passing in the flag:
-DH5_USE_16_API
to the h5cc command line like:
h5cc -DH5_USE_16_API ./example1.c
and it should compile correctly; otherwise you will have to rewrite the code to make use of the 1.8 API.
I am running Lua with a C++ library via swig. When a swig runtime error occurs I would like to know the line which caused the problem. The error message I receive does not have this information.
How can I find which line in the Lua code triggered the error?
For example suppose I have a swig function "swigstringcount" and it takes a string:
local n=4
local m=swigstringcount(n)
print (m,n)
This (obviously wrong) code produces an error on line two. Currently all I get is
error:SWIG_RuntimeError: swigstringcount requires a string
I want it to tell me that line 2 produced the error, like standard Lua error messages.
Based on this method for getting debug info from the Lua C API I've put together a (slightly messy) example of how you can integrate that into a SWIG interface:
%module test
%{
#undef SWIG_fail_arg
#define SWIG_fail_arg(func_name,argnum,type) \
{lua_Debug ar;\
lua_getstack(L, 1, &ar);\
lua_getinfo(L, "nSl", &ar);\
lua_pushfstring(L,"Error (%s:%d) in %s (arg %d), expected '%s' got '%s'",\
ar.source,ar.currentline,func_name,argnum,type,SWIG_Lua_typename(L,argnum));\
goto fail;}
%}
%include <std_string.i>
%inline %{
void func(const std::string& str) {}
%}
This basically replaces the default SWIG_fail_arg macro with a modified one that gets and prints some debug info.
I tested it with the latest SWIG trunk (I think you might be using an older version since the text I see didn't quite match), but I was able to do:
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
> require('test')
> local n=4
> test.func(n)
Error (=stdin:1) in func (arg 1), expected 'std::string const &' got 'nil'
stack traceback:
[C]: in function 'func'
stdin:1: in main chunk
[C]: ?
I seem to have more debug info (i.e. a full stack trace) there already though.
