Обсуждение: plTcl test failed
Got the latest Tcl/Tk 8.0.4 from scriptics, compiled it and installed it with great success. RedHat 5.2 i386, Pentium machine, kernel 2.0.36 All my tcl/tk applications are working fine but : After compiling and installing pltcl packacge, trying to run the tests got the error : QUERY: insert into T_pkey1 values (1, 'key1-1', 'test key'); ERROR: Load of file /usr/local/pgsql/lib/pltcl.so failed: /lib/libtcl8.0.so: undefined symbol: stat Is there any other library that have to be manually added when compiling pltcl, same way as crypt was ? Or the error comes from tcl library ? -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

I succeeded in compiling it but, as usual :-) , adding manually the path to libpq, a -lc and a -lcrypt when linking. Now pltcl works and even passed the included tests. Hope that 6.4.1 would have less problems finding the needed libraries. -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

I hope so too. But we won't find out unless someone who is seeing this
problem (I'm not, because libcrypt isn't a separate shlib on my machine)
pulls down the current sources and tests to see if the fix that's in
there actually works. Preferably before 6.4.1 goes out the door.
Hint hint...

PS: grabbing either the development sources or REL6_4 branch from the
CVS server should do for testing this fix.
PPS: Are we close enough to 6.4.1 that it'd make sense to put up a
snapshot on the FTP server?

Please, specify what .tar.gz and from where should I download in order to test it ? The file postgresql.snapshot.tar.gz (5324902 bytes) from 9 Dec 8:01 would be fine ? -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

I didn't know we were still generating daily snaps. Probably that file
would work, although I imagine it's the development branch and not the
REL6_4 branch.
Perhaps we should be generating snapshots of the REL6_4 branch?

Preferably before 6.4.1 goes out the door. Got postgresql.snapshot.tar.gz (5324902 bytes) from 9 Dec 8:01 I have removed any trace of PostgreSQL 6.4 from my system (directories, libraries). Compiled on my RedHat 5.2 i386 Pentium machine, kernel 2.0.36 with ./configure --with-tcl I has compiled ok but the same errors occured : * for libpgtcl I have to add manually -lcrypt to SHLIBS in Makefile * for pltcl I have to add manually -lc This time, the .so libraries checked with ldd show correct dynamic links to libraries. No more static links. Good news : one of the errors that I have reported (cannot create tables with name containing spaces having an default sequence auto-increment field) was solved. Bad news : another error regarding view names containing spaces, still persist. I am apologising for reporting it again, but maybe someone will find the bug. ------------------------------------------------------------------------ test=>create table students (id int4, name text); CREATE test=> create view "my view" as select * from students; CREATE test=> select * from "my view"; ERROR: nodeRead: Bad type 0 Best regards, -- Constantin Teodorescu FLEX Consulting Braila, ROMANIA

OK, the pltcl problem is easily fixed --- closer inspection of Tcl's
makefiles shows that we weren't using the results read from tclConfig.sh
properly.
The other problem turns out to be even nastier than I feared. It seems
that on some Unix platforms (evidently including teo's Linux version),
the link command that builds a shared library *must* mention any other
shared libraries that that lib depends on.
On other Unix platforms, not only is it not necessary to mention
shared-lib dependencies, but it may actually Not Work.
I find this information in the configure.in file for Tcl, which is
probably a fairly reliable source since Tcl/Tk has the same problem
we do of one shlib depending on another.
(Curiously, Tcl believes that on Linux dependent shlibs should *not* be
mentioned. This leads me to think that there is something unusual or
broken about teo's system. I don't know what, though.)
At this point I have no way to know whether adding -lcrypt to the link
command for libpgtcl.so would break things on more systems than it
fixes ... and so I am not about to just check in that change.
We could try making it system-dependent, using the info in Tcl's
configure file as a guide, but that doesn't strike me as something
I want to try to stick in just a few days before 6.4.1 release either.
The more I learn about this stuff, the more I think that we should get
out of the business of writing our own shlib build/install rules and
let libtool do the work instead.
