Re: [lmi] Building libxml++

[Wendy Boutin]

These are the exact commands I used to successfully build and install
'libxml++-2.14.0' and it's dependencies. These diverge from Evgeniy's
prescription only in these two environment variable settings [with
explanations below]:
  export PKG_CONFIG='pwd'/pkg-config
  export LIBXML_LDFLAGS="-L/usr/local/lib -lxml2"
Evgeniy--if, after reading my explanations below (searching for your name
will take you there quickly), you see reasons why these diversions are
incorrect, I'd be interested in understanding them.

I used our current production development environment instead of creating
the exact one Evgeniy suggested, which had slightly different versions of
the same tools we're using today. I don't know that that accounts for the
various warnings I observe in buildlogs, but since the libraries are built
the warnings are less interesting right now.

0. Download these files:

 ftp://xmlsoft.org/xml/libxml2-2.6.26.tar.gz

libxslt-1.1.17.tar.gz
 ftp://xmlsoft.org/libxslt/libxslt-1.1.17.tar.gz

libxml++_2.14.0.tar.gz

1. Build and install 'libxml2-2.6.26':
address@hidden /c/wendy
$ gzip -d libxml2-2.6.26.tar.gz

address@hidden /c/wendy
$ tar -xf libxml2-2.6.26.tar

address@hidden /c/wendy/libxml2-2.6.26
$ ./configure --enable-shared --disable-static --with-debug

address@hidden /c/wendy/libxml2-2.6.26
$ make >>../libxml2-2.6.26_buildlog00 2>&1

There are many warnings in buildlog, i.e.,

$ make >>../libxslt_buildlog00 2>&1

address@hidden /c/wendy/libxslt-1.1.17
$ make -i install >>../libxslt_installlog 2>&1

3. Build and install 'libxml++-2.14.0':
address@hidden /c/wendy
$ gzip -d libxml++-2.14.0.tar.gz

configure.in: installing `./mkinstalldirs'

Create a pkg-config file with the following content:
   #!/bin/sh
Not knowing if it's obvious to the rest of the world, I'll
mention '\n' is required for this to work successfully.

Evgeniy--I put 'pkg-config' in the root directory and
modified the environment variable to reflect that change:

Set environment variables:
address@hidden /c/wendy/libxml++-2.14.0
$ export PKG_CONFIG=pkg-config

That works for me, but I'd like to know if you specified
  export PKG_CONFIG='pwd'/pkg-config
for a reason that makes mine wrong?

address@hidden /c/wendy/libxml++-2.14.0
$ export LIBXML_CFLAGS=-I/usr/local/include/libxml2

Evgeniy suggested setting this variable:
  export LIBXML_LDFLAGS="-L/usr/local/lib -lxml2"
but I think I really needed this instead:

address@hidden /c/wendy/libxml++-2.14.0
$ export LIBXML_LIBS="-L/usr/local/lib/ -lxml2"

Without that setting the libraries wouldn't compile and there
were many undefined references, i.e.,
 c:/libraries/libxml++-2.14.0/libxml++/attribute.cc:30: undefined 
reference to `xmlGetProp'

address@hidden /c/wendy/libxml++-2.14.0
