为什么IDL不完整

Question

我在Linux上使用OpenDDS3.4.1，并试图手动编译IDL，因为我已经有了该项目的构建系统，只想生成所需的文件并进行集成。这里是我正在使用的测试IDL。

#include "orbsvcs/TimeBase.idl"
module StockQuoter {
#pragma DCPS_DATA_TYPE "StockQuoter::Quote"
#pragma DCPS_DATA_KEY "StockQuoter::Quote ticker"
    struct Quote {
        string ticker;
        string exchange;
        string full_name;
        double value;
        TimeBase::TimeT timestamp;
    };
};

然后按如下方式编译IDL：

$ opendds_idl ./StockQuoter.idl
processing ./StockQuoter.idl
$ tao_idl -I$DDS_ROOT/DDS -I$TAO_ROOT/orbsvcs ./StockQuoter.idl
processing ./StockQuoter.idl

但是，一旦我在生成的idl上使用tao_idl，我就会得到以下内容：

$tao_idl -I$DDS_ROOT/DDS -I$TAO_ROOT/orbsvcs ./StockQuoterTypeSupport.idl
.../ACE_wrappers/bin/tao_idl: "./StockQuoterTypeSupport.idl", line 21: module must contain at least one declaration: ::StockQuoter
.../ACE_wrappers/bin/tao_idl: "./StockQuoterTypeSupport.idl", line 21: module must contain at least one declaration: ::StockQuoter
.../ACE_wrappers/bin/tao_idl: "./StockQuoterTypeSupport.idl", line 21: module must contain at least one declaration: ::StockQuoter
.../ACE_wrappers/bin/tao_idl: "./StockQuoterTypeSupport.idl", line 21: module must contain at least one declaration: ::StockQuoter

当然，结果意味着我无法在pub/subs中注册类型支持，因为所需的对象丢失了，我可以通过查看StockQuoterTypeSupport.idl文件来确认。我查看了OpenDDS开发指南中关于OpenDDS_idl参数的第8章，但似乎什么都不起作用。有什么想法吗？

编辑：
以下是生成的IDL StockQuoterTypeSupport.IDL.

Answer 1

看起来opendds_idl编译器有问题。你能试着用ACE/TAO x.2.3重新编译OpenDDS吗？你可以从download.dre.vanderbilt.edu获得它。我的系统上有这种组合，它可以正常工作。
