C++ AIX5.3上的跨共享库异常问题

我正在为AIX移植一个相当稳定的代码，它已经在Windows、Linux（32位和64位）以及Solaris SPARC和x86中运行。代码在共享库中引发异常：

Environment: IBM AIX 5.3 64 Bits Compiler: GCC 4.6.1

libConfig.so needs:
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libstdc++.a(libstdc++.so.6)
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libgcc_s.a(shr.o)
         /usr/lib/libc.a(shr_64.o)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)

libHostServices.so needs:
         ../../../bin/aix/debug/libConfig.so
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libstdc++.a(libstdc++.so.6)
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libgcc_s.a(shr.o)
         /usr/lib/libc.a(shr_64.o)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)

InterfaceCTest needs:
         /usr/lib/libc.a(shr_64.o)
         ../../../bin/aix/debug/libHostServices.so
         ../../../bin/aix/debug/libConfig.so
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libgcc_s.a(shr.o)
         /unix
         /usr/lib/libcrypt.a(shr_64.o)
         /opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.6.1/ppc64/libstdc++.a(libstdc++.so.6)

下面的示例是使用

OBJECT\u MODE=64生成的

我的GCC生成选项是

过去的三天里，我一直在谷歌上搜索我可能做错的任何事情，但直到现在我什么都没有得到。这个链接对我来说很好，所以我确信这个问题是由于在共享库中抛出异常造成的

有人知道我可能做错了什么吗

谢谢


我做了一个非常简单的测试，现在我非常确定它与我的环境有关：

库
libCore.a
：

标题
Core.h
：

#ifdef __cplusplus
extern "C" {
#endif

void ThrowException();

#ifdef __cplusplus
} //extern "C"
#endif

正文：

可执行文件
CoreCTest
：

#include "Core.h"

int main()
{

    ThrowException();

    return 1;
}

当我执行我的可执行文件时，我得到：

./CoreCTest
terminate called after throwing an instance of 'int*'
IOT/Abort trap(coredump)
有人知道发生了什么事吗？任何帮助都将不胜感激

谢谢
我可以通过向链接器提供链接库的“-lsupc++”选项来解决这个问题。
只是想知道，你的
libCore.a
不是共享库吗？为什么使用
.a
后缀？不，IBM AIX使用与其他unix系统不同的共享库概念。共享库有。一个扩展和运行时可链接的二进制文件有。所以（真是一团糟呵呵）。解决了！！！！！！对于处理同一问题的人，有两个技巧：1-使用BASH作为shell-其他shell会给你混乱的重复符号（难以置信，我知道-）2-缺少-在我的LDFLAGS上共享；3-LDFLAGS允许未解析的符号。新的LDFLAGS=-shared-Wl，-G，-bernotok-Wl，-bnoentry-Wl，-bexpall
#include "Core.h"

int main()
{

    ThrowException();

    return 1;
}

./CoreCTest
