c++ - 移植到 AIX 6.1 (ld : 0711-317 ERROR: Undefined symbol) with Xerces

Question

AIX 6.1

将应用程序从 AIX 5.3 移植到 AIX 6.1，并在 AIX 5.3 中成功构建。我在尝试在 6.1 中构建相同的内容时遇到以下错误。

1. 能够从 C 和 C++ 源代码编译和创建库
2. 尝试使用库创建运行时可执行文件时，出现以下错误

观察结果

以下错误似乎是在尝试调用“libdocxml.a”库中的函数时出现的，该库之前已使用 xlC 编译器成功构建。

使用的编译器:xlC_r，用于构建所有库和应用程序的相同编译器。

注意:

可执行文件在 5.3 中引用该库正确构建。但在 6.1 中同样会出现上述错误。

该库与 xml 解析器相关(xercesparser:XML4C 和 Xerces-C)

请仔细阅读以下错误描述的末尾部分。实际错误在最后定义。

任何帮助将不胜感激。提前致谢。

Answer 1

我之前在 AIX 上见过 Xerces 和 undefined symbol 的问题，该问题与可以指定给 xlc 编译器的符号修饰选项有关。 xerces 是否有可能使用 -qnamemaning 标志(通常设置为 v6 或 ansi)构建？如果您在 xerces 库上运行 dump 或 nm 而没有对符号进行去重整，我敢打赌，它们的符号不会与链接器错误中的重整符号相匹配。
