  • Undefined symbols when migrating ACE application code from ACE 6.1.2 to

    From Shashi Guruprasad@21:1/5 to All on Mon Apr 16 16:52:15 2018
    Hi,

    Currently, our product includes ACE 6.1.2 running on CentOS 6.9 (same as RHEL6). I need to enable IPV6 with ACE_HAS_IPV6, and instead of doing this in ACE 6.1.2, I'm trying to embark on upgrading to a newer version of the ACE library to get all bug fixes
    for the last 5+ years.

    After compiling both ACE 6.4.7 (micro version) and 6.4.0 (stable version), I ran into a few linker errors when linking with our application code:

    undefined reference to `ACE_Condition_Thread_Mutex::ACE_Condition_Thread_Mutex(ACE_Thread_Mutex&, char const*, void*)'
    undefined reference to `ACE_Condition_Thread_Mutex::wait(ACE_Time_Value const*)'
    undefined reference to `ACE_Condition_Recursive_Thread_Mutex::ACE_Condition_Recursive_Thread_Mutex(ACE_Recursive_Thread_Mutex&)'
    undefined reference to `ACE_Condition_Thread_Mutex::broadcast()'
    undefined reference to `ACE_Condition_Thread_Mutex::~ACE_Condition_Thread_Mutex()'
    undefined reference to `ACE_Condition_Thread_Mutex::signal()'

    What is the latest version that I could use where ACE SDK API is backwards compatible with 6.1.2? I could try it one version at a time which is time consuming, which I will eventually do, but wanted to find out if someone on the list already knew.

    Any other guidance is appreciated.

    Thanks,
    Shashi

    Hi,

    Have you also recompiled your application with the newest ACE library?

    Hi Johnny,

    Yes, the errors I posted above were link errors but this was after recompile of the code. I also made sure that the new version include files are present.

    After some trial and error with different versions, I was able to link ACE 6.3.0 version linked against my application. So, somewhere between ACE 6.3.X and 6.4.0, there were some incompatible method signature changes.

    Hi,

    When the code compiles but not links there is something else happening, wouldn't a signature change, else it wouldn't compile.
