<p>
|

Boost.Regex is now capable of performing a configuration check to test whether
|
||||
ICU is already installed in your compiler's search paths. When you build you
|
||||
should see a message like this:
|
||||
</p>
|
||||
<pre class="programlisting"><span class="identifier">Performing</span> <span class="identifier">configuration</span> <span class="identifier">checks</span>
|
||||

<span class="special">-</span> <span class="identifier">has_icu</span> <span class="identifier">builds</span> <span class="special">:</span> <span class="identifier">yes</span>
|
||||
</pre>
|
||||
<p>
|
||||
Which means that ICU has been found, and support for it will be enabled in
|
||||
the library build.

||||

|

|

<p>
|

If instead you see:

</pre>
|

<p>
|

Then ICU was not found and support for it will not be compiled into the library.
|
||||
If you think that it should have been found, then you will need to take a look
|
||||
at the contents of the file <span class="emphasis"><em>boost-root/bin.v2/config.log</em></span>
|
||||
for the actual error messages obtained when the build carried out the configuration
|

check. You will then need to fix these errors by ensuring your compiler gets

invoked with the correct options. The main options that you're likely to pass

ICU is a C++ library just like Boost is, as such your copy of ICU must have
|
||||
been built with the same C++ compiler (and compiler version) that you are
|
||||
using to build Boost. Boost.Regex will not work correctly unless you ensure
|
||||
that this is the case: it is up to you to ensure that the version of ICU
|
||||
you are using is binary compatible with the toolset you use to build Boost.

<p>
|
||||
And finally, if you want to build/test with multiple compiler versions, all
|
||||
with different ICU builds, then the only way to achieve that currently is to
|
||||
modify your user-config.jam so that each toolset has the necessary compiler/linker
|
||||
options set so that ICU is found automatically by the configuration step (providing
|
||||
the ICU binaries use the standard names, all you have to add is the appropriate
|
||||
header-include and linker-search paths).

The Regex library is "just a bunch of source files": nothing special

is required to build them.

|

You can either build the files under boost-path/libs/regex/src/*.cpp as a library,
|
||||
or add them directly to your project. This is particularly useful if you need
|
||||
to use specific compiler options not supported by the default Boost build.
