Hi, i am having a problem with a test installation of postgres 8.0.3 on a 64-bit power5 system. Let me say first that the system seems to work correctly when compiled in 32-bit mode (which seems to be standard compile mode with gcc on this installation). I compiled postgres in 64-bit mode by adding the following switches in the make file: To the gcc lines: -m64 -mcpu=power5 -mtune=power5 To ld lines: -m elf64ppc Compiling in 64-bit mode also seems to work, but there is an error when trying to access the postmaster process: Server starts: [postgres@testxx pg803]$ bin/postmaster -D /opt/test/data LOG: could not send test message on socket for statistics collector: Destination address required LOG: disabling statistics collector for lack of working socket LOG: database system was shut down at 2005-09-15 13:42:43 CEST LOG: checkpoint record is at 0/AB8AD8 LOG: redo record is at 0/AB8AD8; undo record is at 0/0; shutdown TRUE LOG: next transaction ID: 544; next OID: 17230 LOG: database system is ready Client connects: [root@testxx pg803]# bin/psql -U nsadmin -l psql: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. Server says: LOG: setsockopt(TCP_NODELAY) failed: Operation not supported Did anyone have a similar problem and can provide some help? TIA, peter Ps: The system is using the following gcc config: Reading specs from /usr/lib/gcc/ppc64-redhat-linux/3.4.3/specs Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-java-awt=gtk --host=ppc64-redhat-linux --build=ppc64-redhat-linux --target=ppc64-redhat-linux --with-cpu=default32 Thread model: posix gcc version 3.4.3 20050227 (Red Hat 3.4.3-22.1) ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
