Hi, We have in ACE a Singleton template that is implemented in a C++ template with a static member.
We are now using a test program that is linked with the ACE dll and checks this singleton pointer. The program uses another dll that also uses ACE, but there the singleton pointer is different, so we don't have concrete singleton. This does work with msvc for ARM, doesn't work with CEGCC for x86 (haven't tried CEGCC/ARM yet). Does this ring a bell to someone? We are not using the GCC 4 visibility feature? Danny, the reproducer program is ACE_wrappers/tests/Based_Pointer_Test.cpp, see line 136 for the test that fails. It uses the Based_Pointer_Test_Lib.cpp for the second DLL. The error we get is: May 14 14:41:23.247 2...@lm_debug@(85065734|85131270) Starting Based_Pointer_Test test at Thu May 14 2009 14:41:23.250000 May 14 14:41:23.397 2...@lm_error@ACE_Based_Pointer_Repository is not a singleton in DLL 1A028614 1A0271D4 May 14 14:41:23.485 2...@lm_error@MMAP pool mapping not present May 14 14:41:23.547 2...@lm_error@Persistent MMAP Memory Pool not mapped May 14 14:41:23.746 2...@lm_error@New base address not mapped after MMAP remap May 14 14:41:23.777 2...@lm_debug@(85065734|85131270) Ending Based_Pointer_Test test at Thu May 14 2009 14:41:23.777000 Does this ring a bell to someone?
