lua: error loading module 'luapb' from file './../luapb.so':
libprotobuf.so.9: cannot open shared object file: No such file or directory

需要接rpc

hi，先感谢老兄，这个项目真棒！

但是使用的时候遇到问题，我在cocos2dx中集成了luapb，运行时先依照test.lua编写了test.proto，然后运行。如果我首先调用test.lua里的代码，会打印出正确的结果，但是如果我调用了cocos2dx绑定的那些（用tolua绑定，还有些ui操作什么的）就会报错" attempt to index local 'msg' (a userdata value)"
请教老兄，这个可能是怎么引起的，有什么解决办法比较好？

非常感谢！

如何使用luapb

if(field->type() == google::protobuf::FieldDescriptor::TYPE_INT32)
has no type TYPE_SFIXED32 or TYPE_SFIXED64.

Using field->cpp_type() is better.

我把这个库用于安卓时，import无法读入文件，主要是Importer的OpenVirtualFile方法中的open操作无法打开文件

作为一个刚接触的新手，对于编译so和dll完全不懂，能简单教下怎么编译dll和so吗？谢谢了。

我用lua5.3和protobuf-3.0.0编译so文件，改了makefile的两个地方
LUA_INC_DIR ?= /f/lua-5.3.5/src
PROTOBUF_INC_DIR ?=/F/protobuf-3.0.0/src
编译时候报错：
$ make
g++ -g -Wall -fpic -c -Iinclude -I/f/lua-5.3.5/src -I/F/protobuf-3.0.0/src src/*.cc
src/LuaPB.cc:486:30: error: elements of array 'const luaL_reg lib []' have incomplete type
static const struct luaL_reg lib[] =

current: int val = static_cast(luaL_checkinteger(L, 3));
should be: int val = static_cast(lua_toboolean(L, 3));
I guess..
After recompiling the lib boolean type set is correct and there is no error msg.

require("luapb");

--package lm;
--message test
--{
-- required int32 uid = 1;
-- required int32 param = 2;
-- optional string param1 = 3;
-- repeated string param2 = 4;
--};

pb.import("test.proto");

function testAdd()
local msg = pb.new("lm.test");
msg.uid = 12345;
msg.param = 9876;
msg.param1 = "zjx";
--print("type: " .. type(msg.param2));
msg.param2.add("first");
msg.param2.add("second");
msg.param2.add("three");

print("uid: " .. msg.uid);
print("param: " .. msg.param);
print("param1: " .. msg.param1);

for i = 1, msg.param2.len() do
    local value = msg.param2[i];
    print("i: " .. i .. " value: " .. value); 
end
print("str: " .. pb.tostring(msg));
print("hello world");

end
testAdd()
testAdd()

封装成函数的时候，多次调用，repeated filed的个数会和之前调用的累加，比如这个函数里
msg.param2.add("first");
msg.param2.add("second");
msg.param2.add("three");
第一次调用testAdd()执行了add了三次， msg.param2.len() 为3
第二次调用testAdd()又执行了add了三次， 局部作用域，msg.param2.len() 应该为3，但实际为6

1,proto文件
package db;
enum Source{
MYSQL= 1；
INFORMIX=2;
}
message Message{
required Source sr = 1;
required string conStr = 2;
}

设置为MYSQL,但是反序列化后
print(msg.sr)
输出为sr

如题

提示 bad argument #3 to '__newindex' (number expected, got boolean)

I cant find anything that will deal with
" field->type() == google::protobuf::FieldDescriptor::TYPE_MESSAGE "
in pb_set and pb_repeated_set functions. Is it intentionally or me just can't understand? I can't put fields of type another msg hence i found, that there is no code to deal with this type. I see such code in pb_get , pb_repeated_get and pb_repeated_add thou.
Any help?
