Обсуждение: gmake Errors: pg_backup_archiver.c: undefined reference to `lo_create'

Hello,

When I tried to install postgresql 8.1.4, I got the following errors.

Could someone tell me what are missing or wrong please?
==============================================

./configure --prefix='/home/postgresql/' --without-docdir --without-readline

It looks to me like ld is trying to link pg_dump against a pre-8.1 copy
of libpq (lo_create is new in libpq as of 8.1).  Question is why?  You
did not show us the link command, nor mention what platform this is.

That's hardly full results from gmake --- it looks like it re-used a
whole pile of pre-existing .o files.  Perhaps what you need is a "make
distclean" and start again.

The only other theory I can think of is that the linker is picking up
an old libpq.so from /home/postgresql/lib because of the -rpath switch
... which it should not be doing, but maybe it is anyway.  If there's
an 8.0 libpq.so there, try getting rid of it.

You are absolutely correct. It is because of the libpg.so.

I used the central gcc before, and -rpath was linked to the 8.0 libpg.so.

Now I specified the local gcc and installed version 8.1.4 successfully
this time.

Thanks a lot for all your kind help!
