POLua Error: "attempt to call a string value" under Android NDK?
text
Body
copied!<p>My Lua scripts are compiled by <a href="http://loop.luaforge.net/release/preload.html" rel="nofollow">LOOP</a>, the compiled scripts module runs well in a desktop machine(OSX 10.7.5). But when I run it under Android phone (Android 2.3.6), it always fails and complains <code>attempt to call a string value</code>. The same scripts can run also without problems in script (not compiled) way in the same phone. </p> <p>Lua 5.1.5 and Android NDK r8b are used in the test.</p> <p>The error in logcat:</p> <pre class="lang-none prettyprint-override"><code>12-26 09:40:26.934: E/libb22luapre(8190): Failed to run script: attempt to call a string value </code></pre> <p>The C code snippet (error handling code removed for simplicity):</p> <pre class="lang-c prettyprint-override"><code>const char script[] = "require \"hello.world\"\n" "require \"anothermodule\"\n" "hello.world.test2()"; luaL_loadstring(L, script); lua_pcall(L, 0, LUA_MULTRET, 0); </code></pre> <p>I dumped the preloaded table, these required modules already exists (loaded successfully). </p> <p>I searched the web, still can not find a solution. Any advice will be greatly appreciated.</p> <p>[UPDATED] I compiled lua command for android and embed the compiled lua scripts in it. The error is just the same as above.</p> <pre class="lang-none prettyprint-override"><code>$ adb shell $ cd /data/local $ ls tmp lua dump_preload.lua $ ./lua dump_preload.lua --- print table --- preload test function: 0x376f0 anothermodule function: 0x37718 hello.world function: 0x376b0 --- print table --- loaded string table: 0x33828 debug table: 0x37098 package table: 0x33d30 _G table: 0x32528 io table: 0x34e80 os table: 0x357b8 table table: 0x332c0 math table: 0x36530 coroutine table: 0x33988 --- print table --- loaders 1 function: 0x33ed8 2 function: 0x33ef8 3 function: 0x33f18 4 function: 0x33f38 $ ./lua Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio > require 'test' attempt to call a string value stack traceback: [C]: ?
