Hi, there's one more thing which IMO should be mentioned on the platform-specific site: On AIX 5.3 there is a bug where 'thread_creds_t' is a global variable instead of a typedef in /usr/include/sys/threads.h In case of C, the linker may give 'duplicate symbol' on this one. What can happen in case of C++, see http://www-128.ibm.com/developerworks/forums/dw_thread.jsp?forum=747&thread=119546&cat=72 The workaround is to define 'thread_creds_t' to nothing: -Dthread_creds_t= This only affects AIX 5.3, not AIX <= 5.2. According to IBM, the fix for this APAR IY90737 is incorporated into Service Pack 5300-05-04. Thanks, /haubi/
