Our AIX 6 build is not seeing this problem (using XL C/C++ 10.1)
Our AIX 7 build isn’t either (XL C++

What config files are you using?

Subject: [ace-users] Symbol not found after upgrading ace version 6.4.3.


To resolve the issue of undefined symbols for (ACE_Singleton::instance(), ACE_Singleton::instance_i(), ACE_Singleton::singleton_) I did explicit instantiation, i.e by adding the following lines into the file Based_Pointer_Repository.cpp,

template ACE_Based_Pointer_Repository * ACE_Singleton<ACE_Based_Pointer_Repository,ACE_RW_Thread_Mutex>::instance (void);
template ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex> *& ACE_Singleton<ACE_Based_Pointer_Repository,ACE_RW_Thread_Mutex>::instance_i (void);
template ACE_Singleton<ACE_Based_Pointer_Repository, ACE_RW_Thread_Mutex> * ACE_Singleton <ACE_Based_Pointer_Repository,ACE_RW_Thread_Mutex>:: singleton_=0 ;

Presently, getting the following error while starting the application. I have built ACE version 6.4.3 on AIX 6.1  machine. Could you please help to resolve this issue. Also, please suggest if any compiler option available for this.

rtld: 0712-001 Symbol __ct__13ACE_SingletonXT28ACE_Based_Pointer_RepositoryT19ACE_RW_Thread_Mutex_Fv was referenced
      from module /scratch/pin3050/opt/ifw/lib/libace64.a(), but a runtime definition
      of the symbol was not found.

Sustem information:

Compiler version
/usr/vacpp/bin/xlCcore_r -qversion
IBM XL C/C++ for AIX, V11.1 (5724-X13)
Version: 11.01.0000.0003
