Re: [PATCH] Re: Diff Project compilation problem

I propose we add the FAQ entry similar to the following:

<p>One typical error message class involve the following pattern:</p>
<pre>
../../subversion/../*.so: undefined reference to `function_not_worked_on'

collect2: ld returned 1 exit status
make: *** [subversion/something/something] Error 1
</pre>

<p>There are a couple of common causes of this kind of problem:</p>

<p>1. You could be linking to your own installed libraries.</p>

<p>Workaround 1: Remove any installed subversion libraries from
subdirectories of your PREFIX directory. A discussion of this sort of
cleanup is available at <link to Karl Fogel's post in the hacking
guide.</p>

<p>Workaround 2: Specify a different prefix. For example:
<br /><code>"./configure --prefix=/dev/null ## Doesn't exist"</code></p>

<p>2. You may have run <code>"svn up"</code> so that your build system
files are now stale:</p>
<p>Rerun <code>"./autogen.sh; make"</code> or
         <code>"./autogen.sh; ./config.nice; make"</code>
         to run configure with the same arguments as the last invocation
</p>

Potential addition:

If you have altered a build system file,
<a href="link_to_permutation_table">
see here for information</a> how to refresh your build.

(link to build system doc entry that holds the decision matrix that
explains this bit, see below)

Karls' advice would not have helped me in this situation, the
--prefix=/dev/null was the best soln. for my problem. He addresses
build system changes for the most part.

I could add the following table:

Changed File Re-run script Output Next action
==============================================================
Makefile.in configure Makefile make
build.conf gen-make.py build-outputs.mk configure
build/gen-make/ " " "
configure.ac autogen.sh configure "
build/ac-macros/ " " "
---------------------------------------------------------------

However, I think something like that belongs in the section about the
build system, and if the above table(or a variant thereof) is liked,
we could put a link in the faq entry that points to it.

========================================================================

I could attempt to find-replace. There are 2559 instances, including
page translations -- would any commiter like to make that change?
