In nsprpub/pr/include/prnetdb.h, line 64, PR_NETDB_BUF_SIZE is defined as #if (defined(AIX) && defined(_THREAD_SAFE)) || defined(OSF1) #define PR_NETDB_BUF_SIZE sizeof(struct protoent_data) #else #define PR_NETDB_BUF_SIZE 1024 #endif However when this is used in netwerk/dns/public/_xpidlgen/nsIDNSListener.h, struct protoent_data is not defined. (struct protoent_data is defined in /usr/include/netdb.h). I added '#include <netdh.h>' in prnetdb.h, however that wasn't enough for some unkonwn reason... The error message generated is: xlC_r -o nsSocketTransport.o -c -DAIX -DAIX4_3 -g -DMOZILLA_CLIENT -DNSCAP_DISAB ... -I/usr/local/include -qflag=w:w -DPIC nsSocketTransport.cpp "../../../dist/include/nsCppSharedAllocator.h", line 90.16: 1540-252: (W) The destructor for "unsigned short" does not exist. The call is ignored. "../../../dist/include/nsIDNSListener.h", line 14.24: 1540-106: (S) The size of "protoent_data" is unknown in "sizeof" expression.

I am not seeing this on my build of today. What I did find is that: nsSocketTransport.cpp includes nsIDNSListener.h nsIDNSListener.h includes prnetdb.h prnetdb.h include prio.h prio.h includes prinet.h prinet.h includes <netdb.h> <netdb.h> declares protoent_data one thing, are you pulling NSPR yourself or are you allowing client.mk to pull it for you? I noticed that you have MOZILLA_CLIENT defined. I believe this will compile NSPR with NSPR threads instead of posix threads, are you doing this for a reason?

I downloaded a new nightly build, removed itools-R6.3 from the PATH (to go back to the AIX standard makedepend), tidied up a few environmental variables (SOCKS_BANNER, DB2INSTANCE, DOCUMENT_DIRECTORY) and rebuilt from scratch. It hasn't finished yet, but it appears to have successfully compiled nsSocketTransport.cpp. I don't know where the -DMOZILLA_CLIENT is coming from, there is nothing in the environment that looks related, and I'm using the standard command-line # make -f client.mk pull_and_build_all (I got CVS working) I have made no modifications to the client.mk file. I had planned to upload a complete make log, but I deleted it when I had to restart the make (disk full...) Thanks for your patience, Ciaran
