我已经将一个 c++ 代码从一个开放的 solaris 操作系统移植到了 Redhat 4 操作系统。在此代码段中，我收到错误消息：

    AsciiFileName = new char [1024];
    cout<<"HandleFile is getting called "<<endl;
    /// Converting the file name to ascii.
    FileName += strFileName;
    FileName.ConvertToAscii( AsciiFileName );

    /// Get handle to the shared object file.
    Handle = dlopen( AsciiFileName, RTLD_LOCAL | RTLD_LAZY );
    cout<<"Handle = dlopen( AsciiFileName, RTLD_LOCAL | RTLD_LAZY ); is getting called AsciiFileName"<<AsciiFileName<<endl;
    if (!Handle)
    {
    cout<<"Handle is NULL"<<endl;
    cout<<dlerror()<<endl;
exit(EXIT_FAILURE);

我得到的错误是：

invalid elf header linux

它无法打开so文件。这是它的相关日志

/trnuser1/rmtrain/DevelopmentEnv/Telstra/USM/dat/CnEModules/libGCVCore.so：当前 ar 存档

那是一个静态库（存档），应该是.a，而不是.so. 你不能用dlopen.

您可能将 libGCVCore.so 从 Solaris 机器复制到 RedHat 机器。Solaris 机器很可能具有与 RedHat 不同的体系结构（Sparc？）。您可以通过键入以下内容进行确认：

file libGCVCore.so

此命令应打印有关您尝试链接的库的目标体系结构的信息。
