<ul>
<li>It is not possible to build this version of base on HP-UX due to C++
issues which appear to be bugs in the HP-UX compiler.</li>
<li>Parallel make (<tt>make -j</tt>) does not work on cygwin-x86 targets,
probably due to a missing dependency in the EPICS build rules.</li>
<li>When shutting down an IOC on a recent version of GNU/Linux (one that
includes the NPTL threading library) various messages may appear, such as:
<li>Some older Perl versions do not properly install the xsubpp program. This
will prevent the build in src/cap5 from completing &mdash; the build will
finish with an error like this:
<blockquote>
<pre>FATAL: exception not rethrown</pre></blockquote>
<blockquote><pre>/bin/sh: /bin/xsubpp: not found
make[3]: *** [Cap5.c] Error 1
make[3]: Leaving directory `/home/phoebus3/ANJ/epics/base/3-14-dev/src/cap5/O.solaris-x86'
make[2]: *** [install.solaris-x86] Error 2
make[2]: Leaving directory `/home/phoebus3/ANJ/epics/base/3-14-dev/src/cap5'
make[1]: *** [cap5.install] Error 2
make[1]: Leaving directory `/home/phoebus3/ANJ/epics/base/3-14-dev/src'
make: *** [src.install] Error 2</pre></blockquote>
<blockquote>
<pre>epicsThread: Unknown C++ exception in thread "CAC-UDP" at ...</pre>
<pre>terminate called after throwing an instance of ''</pre>
</blockquote>
As long as you don't intend to use the Perl5 CA interface this error is
harmless, as cap5 is the last directory to be compiled in Base. If you need
the Perl5 CA inteface, fix your Perl installation so that the perl binary
and the xsubpp program (or soft links to them) are both found in the same
directory.</li>
These errors are caused by the implementation of the pthread_cancel()
mechanism in NPTL, which uses the C++ exception mechanism without providing
any means to distinguish the cancel exception to regular C++ exception
handlers. It is possible that they might also occur when a CA client
application exits (or closes its connection to the CA library).</li>
</ul>
