Thread: uuids on freebsd
Has anyone ever managed to get uuid generation working on FreeBSD? There seems to be no way to build contrib/uuid-ossp successfully, and no apparent agreement anywhere as to whether this is problem with pg or with the misc/ossp-uuid port. (I tried this, without success, a couple of weeks back in response to a question on IRC. The only solution I could come up with was to knock off a quick uuid-freebsd module that uses the base system uuid functions rather than the ossp ones. I could put this on pgfoundry if there isn't likely to be a real fix in the near future.) -- Andrew (irc:RhodiumToad)

So what's the problem? Error messages etc.?

Peter> So what's the problem? Error messages etc.? On my system (7.1-pre on amd64), it refuses to link (presumably due to the misc/ossp-uuid port building the .a without -fPIC). The guy whose report on IRC caused me to look into it had a very similar system, but in his case the module did link, but segfaulted the backend if called. I get a segfault too if I force misc/ossp-uuid to build with -fPIC: test=# select uuid_generate_v1(); server closed the connection unexpectedly (gdb) where #0 0x000000087d404fb5 in uuid_export () from /usr/local/lib/postgresql/uuid-ossp.so #1 0x000000087d40598a in uuid_make () from /usr/local/lib/postgresql/uuid-ossp.so #2 0x000000087d4031d8 in uuid_nil () from /usr/local/lib/postgresql/uuid-ossp.so #3 0x0000000000556cf9 in ExecMakeFunctionResult () I can try this on another box with a debug-enabled pg build later. -- Andrew (irc:RhodiumToad)

The problem, unsurprisingly, is that the call to uuid_create in contrib/uuid-ossp.c ends up resolving to the libc function rather than to the ossp libuuid.a one. Since the functions do completely different things, hilarity ensues. It can apparently be made to work by jumping through enough flaming hoops: you have to build misc/ossp-uuid with CFLAGS=-fPIC, and then build contrib/uuid-ossp with LDFLAGS_SL=-Wl,-Bsymbolic (but I think this would break again if misc/ossp-uuid ever installed a .so rather than just the .a). So I don't think this is a realistic fix. -- Andrew (irc:RhodiumToad)

I managed to hack the old contrib/uuid so it would use the functions from Linux e2fs uuid on 8.0/8.1/8.2. I might have time soon to see if I can get that to work on 8.3. -- DLL

It's now on pgfoundry :) Cheers, David. -- David Fetter <david@fetter.org> http://fetter.org/ Phone: +1 415 235 3778 AIM: dfetter666 Yahoo!: dfetter Skype: davidfetter XMPP: david.fetter@gmail.com Remember to vote!
