我正试图围绕omniORB 准备使用它来与我们将获得的使用CORBA 的软件交互。我使用的策略是在omniORB（回声示例，特别是eg3_impl和eg3_cc）中举一个例子，并从接收到的软件中混合idl，直到它完成我想要的。为此，我试图将我正在编写的软件与omniORB 堆栈的其余部分隔离开来（即我正在尝试编写一个依赖于已编译库的独立makefile）。我正在使用从 sourceforge 下载的omniORB-4.2.3（通过omniORB-support.com 链接）。
我遇到的问题是，从独立 makefile 编译的示例似乎存在编译树示例没有的内存问题；
- 从独立 Makefile 编译的示例试图解除分配不是“malloc()”或“new”的指针。（烦人，但不是炫耀）
- 从独立 Makefile 编译的示例似乎没有正确记录字符串指针。（一个展示者）。
两个示例之间的源文件相同；唯一的区别是，非独立示例使用内置在omniORB树中的makefile结构，独立软件使用我编写的编译脚本，基于我在构建echo示例时观察到makefile结构所做的事情。
这是我的脚本：
WHICH_BUILD_DIR=build2
WHICH_VERSION=omniORB-4.2.3
INCLUDE_G_PLUS_PLUS="-I./idl_artifacts/ -I../${WHICH_VERSION}/include -I. -I../${WHICH_VERSION}/${WHICH_BUILD_DIR}/include"

分析这两次运行时，我注意到损坏代码中的“bind_new_context”消息中缺少“test”和“my_context”的字符串......（这就是命名服务以“无效名称”异常响应的原因）。在断码中，消息更小，消息前面的size字段反映了更小的尺寸。
这与在损坏的代码中没有参数（或使用 NULL 参数）调用“bind_new_context”函数是一致的。但是两个示例都使用相同的源代码；使用相同的 rootContext 和 contextName 变量调用相同的 bind_new_context 函数，并以相同的方式填充。所以我认为我的构建脚本引入了某种环境混淆，而从omniORB编译的版本中不存在。这也可以解释为什么清理代码也被破坏了。但我花了 2 天时间试图摆脱它，但我已经空了。
有任何想法吗？
编辑：这是我基于构建脚本的树的 makefile 的输出。存在差异，但似乎没有实质性的差异。
