Обсуждение: configure problem --with-libxml
Hello, I try to compile postgres with SQL/XML, but I finished on checking libxml/parser.h usability... no checking libxml/parser.h presence... no checking for libxml/parser.h... no configure: error: header file <libxml/parser.h> is required for XML support I have Fedora Core 6, and libxml2-devel I have installed. I checked parser.h and this file is in /usr/include/libxml2/libxml/ directory I am sorry, but configure file is spenish vilage for me, and I can't correct it.

I solved it via symlink, but this is much cleaner Maybe configure scripts needs little bit more inteligence. All people on RH systems have to do it :-( Thank you Pavel Stehule >From: Stefan Kaltenbrunner <stefan@kaltenbrunner.cc> >To: Pavel Stehule <pavel.stehule@hotmail.com> >CC: pgsql-hackers@postgresql.org >Subject: Re: [HACKERS] configure problem --with-libxml >Date: Fri, 22 Dec 2006 09:49:00 +0100 > >Pavel Stehule wrote: >>Hello, >> >>I try to compile postgres with SQL/XML, but I finished on >> >>checking libxml/parser.h usability... no >>checking libxml/parser.h presence... no >>checking for libxml/parser.h... no >>configure: error: header file <libxml/parser.h> is required for XML >>support >> >>I have Fedora Core 6, and libxml2-devel I have installed.

another way is: export CPPFLAGS=$(xml2-config --cflags); ./configure --with-libxml I think that such thing can be used in configure script itself, overwise a lot of people will try, fail and do not use SQL/XML at all.

The reason why I did not do this was that this could resolve to -I/usr/include or -I/usr/local/include, but adding such a standard path explicitly is wrong on some systems. Clearly, we need to improve this, but I don't know how yet. Ideas welcome. -- Peter Eisentraut http://developer.postgresql.org/~petere/

But if people on such a system want to use libxml2, and they install it in /usr/include then they're screwed anyway. There's no way to tell the compiler to use only some files in a directory. Put another way, if adding the include path for libxml2 breaks their build environment, they can't use libxml2. Have configure play dumb isn't helping anyone. It won't work on any more or less systems. Have a nice day, -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > From each according to his ability.

That's not the point, the point is that an *explicit* -I can be wrong
(because it can change the search order of the default directories).
Perhaps it'd be worth trying to add xml2-config's output only if the
first probe for the headers fails?
