<center><b><big><big>Changes and Additions to CppAD During 2007</big></big></b></center>
<br/>
<b><big><a name="Introduction" id="Introduction">Introduction</a></big></b>
<br/>
This section contains a list of the changes to CppAD during 2007
(in reverse order by date).
The purpose of this section is to
assist you in learning about changes between various versions of CppAD.
<br/>
<br/>
<b><big><a name="12-29" id="12-29">12-29</a></big></b>
<br/>
License conversions missed the copyright message at the top
in the following special cases:
<code><font color="blue">makefile.am</font></code>, <code><font color="blue">makefile.in</font></code>, and
<code><font color="blue">omh/license.omh</font></code>.
<br/>
<br/>
<b><big><a name="12-25" id="12-25">12-25</a></big></b>
<br/>
The <a href="install.xml" target="_top"><span style='white-space: nowrap'>install</span></a>
instructions have been improved.
<br/>
<br/>
<b><big><a name="12-21" id="12-21">12-21</a></big></b>
<br/>
The <a href="installunix.xml#--with-Documentation" target="_top"><span style='white-space: nowrap'>--with-Documentation</span></a>
option on the <code><font color="blue">configure</font></code> command line caused an error on some
systems because it attempted to copy to many files.
This has been fixed by copying the directory instead of the individual files.
<br/>
<br/>
<b><big><a name="12-08" id="12-08">12-08</a></big></b>
<br/>
By mistake, the documentation <a href="license.xml" target="_top"><span style='white-space: nowrap'>License</span></a>
statement
for the GPL distribution was the same as for the CPL distribution.
This has been fixed.
<br/>
<br/>
<b><big><a name="12-05" id="12-05">12-05</a></big></b>
<br/>
Change the name of the spec file from
<code><font color="blue"><span style='white-space: nowrap'>cppad-</span></font><i><font color="black"><span style='white-space: nowrap'>yyyymmdd</span></font></i><font color="blue"><span style='white-space: nowrap'>.spec</span></font></code>
to <code><font color="blue">cppad.spec</font></code>.
<br/>
<br/>
<b><big><a name="12-04" id="12-04">12-04</a></big></b>
<br/>
Add the capability for the RPM spec file to use a different
prefix directory.
<br/>
<br/>
<b><big><a name="12-03" id="12-03">12-03</a></big></b>
<br/>
This is the first version with the rpm spec file
<code><font color="blue">cppad.spec</font></code>.
<br/>
<br/>
<b><big><a name="12-02" id="12-02">12-02</a></big></b>
<br/>
Add the
<code><font color="blue"><span style='white-space: nowrap'>DESTDIR=</span></font><i><font color="black"><span style='white-space: nowrap'>directory</span></font></i></code>
option on the
<a href="installunix.xml#make install" target="_top"><span style='white-space: nowrap'>make install</span></a>
command line.
<br/>
<br/>
<b><big><a name="11-29" id="11-29">11-29</a></big></b>
<br/>
The <a href="std_math_ad.xml" target="_top"><span style='white-space: nowrap'>std_math_ad</span></a>
function <code><font color="blue">sqrt</font></code> did not link properly
when
<code><i><font color="black"><span style='white-space: nowrap'>Base</span></font></i></code>
was <code><font color="blue">AD<double></font></code>.
This has been fixed.
<br/>
<br/>
<b><big><a name="11-23" id="11-23">11-23</a></big></b>
<br/>
The routines <code><font color="blue">nan</font></code> and <code><font color="blue">isnan</font></code> were failing
for some systems because they use <code><font color="blue">nan</font></code> and or <code><font color="blue">isnan</font></code>
as preprocessor symbols.
This has been fixed; see <a href="nan.xml#Include.Macros" target="_top"><span style='white-space: nowrap'>macros</span></a>
.
In addition, the example and test <a href="nan.cpp.xml" target="_top"><span style='white-space: nowrap'>nan.cpp</span></a>
has been added.
<br/>
<br/>
<b><big><a name="11-18" id="11-18">11-18</a></big></b>
<br/>
Speed tests for <code><font color="blue">tape_values</font></code> branch were not better than trunk,
so the good parts of that branch (but not all) were merged into the trunk.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The interface specifications for
<a href="base_require.xml" target="_top"><span style='white-space: nowrap'>base type requirements</span></a>
have been changed so that
CppAD would compile with <code><font color="blue">gcc 4.1.1</font></code>
(which requires more definitions before use in template functions).
This changed of requirements is demonstrated by the
<a href="base_complex.hpp.xml" target="_top"><span style='white-space: nowrap'>base_complex.hpp</span></a>
and <a href="base_adolc.hpp.xml" target="_top"><span style='white-space: nowrap'>base_adolc.hpp</span></a>
examples.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The problem with newer C++ compilers requiring more definitions before use
also required the user to know about <code><font color="blue">float</font></code> and <code><font color="blue">double</font></code>
definitions for the standard math
functions in the CppAD namespace;
see <a href="base_std_math.xml" target="_top"><span style='white-space: nowrap'>base_std_math</span></a>
.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <code><font color="blue">example/test_one.sh</font></code> and <code><font color="blue">test_more/test_one.sh</font></code>
scripts were modified so that one only need specify the test file name
(does not also need the test routine name). Some of the test routine
declarations were changed from
<code><i><font color="black"><span style='white-space: nowrap'>name</span></font></i><font color="blue"><span style='white-space: nowrap'>()</span></font></code>
to
<code><i><font color="black"><span style='white-space: nowrap'>name</span></font></i><font color="blue"><span style='white-space: nowrap'>(void)</span></font></code>
to make this possible.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The program <code><font color="blue">test_more/test_more</font></code> was changed to always
report the memory leak test results (same as <code><font color="blue">example/example</font></code>).
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="printfor.xml" target="_top"><span style='white-space: nowrap'>PrintFor</span></a>
function was putting an unused variable in the tape.
This has been fixed.
<br/>
<br/>
<b><big><a name="11-06" id="11-06">11-06</a></big></b>
<br/>
Added the <code><font color="blue">-DRAD_EQ_ALIAS</font></code> compiler flag to the
<a href="speed_sacado.xml" target="_top"><span style='white-space: nowrap'>Sacado speed tests</span></a>
.
In addition, compiler flag documentation was included for
Sacado and all the other speed tests.
<br/>
<br/>
<b><big><a name="11-05" id="11-05">11-05</a></big></b>
<br/>
MS project files have been added for running the
<a href="speed_cppad.xml" target="_top"><span style='white-space: nowrap'>cppad</span></a>
and
<a href="speed_double.xml" target="_top"><span style='white-space: nowrap'>double</span></a>
speed tests.
<br/>
<br/>
<b><big><a name="11-04" id="11-04">11-04</a></big></b>
<br/>
The <code><font color="blue">cppad/config.h</font></code> file was not compatible with the
Windows install procedure and
the Windows project's could not find a certain include file.
This has been fixed.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="installunix.xml" target="_top"><span style='white-space: nowrap'>unix install</span></a>
procedure has been modified
so that the one configure flag
<code><font color="blue">--with-Speed</font></code>
builds all the possible executables related to the speed testing.
<br/>
<br/>
<b><big><a name="11-03" id="11-03">11-03</a></big></b>
<br/>
Improve the <a href="speed_main.xml" target="_top"><span style='white-space: nowrap'>speed_main</span></a>
documentation and output
(as well as the title for other sections under <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
).
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The subversion copy of the <a href="installunix.xml#Configure" target="_top"><span style='white-space: nowrap'>configure</span></a>
script
was not executable.
This has been fixed.
<br/>
<br/>
<b><big><a name="11-02" id="11-02">11-02</a></big></b>
<br/>
The instructions for downloading the current version using
<a href="download.xml#Subversion" target="_top"><span style='white-space: nowrap'>subversion</span></a>
have changed.
The user should now directly edit the file
<code><font color='blue'><pre style='display:inline'>
trunk/configure
</pre></font></code>
in order to set the correct date for the installation
and to build the corresponding documentation.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
section has been slightly reorganized
(the main program and utilities have been separated).
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Add <a href="speed_double.xml" target="_top"><span style='white-space: nowrap'>speed_double</span></a>
for testing the speed of evaluating
functions in <code><font color="blue">double</font></code> as apposed to gradients using AD types.
<br/>
<br/>
<b><big><a name="11-01" id="11-01">11-01</a></big></b>
<br/>
The instructions for downloading the current version using subversion
have changed.
The user must now execute the command
<code><font color='blue'><pre style='display:inline'>
./build.sh version
</pre></font></code>
in order to set the correct version number for her (or his) installation.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Add the return status for all the correctness tests
to the documentation; see <code><font color="blue">make test</font></code>.
<br/>
<br/>
<b><big><a name="10-30" id="10-30">10-30</a></big></b>
<br/>
The download instructions did not update current version number
and this broke the links to the current tarballs.
This has been fixed.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The documentation for <a href="det_by_minor.xml" target="_top"><span style='white-space: nowrap'>det_by_minor</span></a>
and <a href="det_by_lu.xml" target="_top"><span style='white-space: nowrap'>det_by_lu</span></a>
has been improved.
The order of the elements in <a href="det_of_minor.xml" target="_top"><span style='white-space: nowrap'>det_of_minor</span></a>
has been
corrected (they were transposed but this did not really matter
because determinants of transposes are equal).
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The makefiles in the distribution have been changed so that
one can run configure from a directory other than the distribution directory.
<br/>
<br/>
<b><big><a name="10-27" id="10-27">10-27</a></big></b>
<br/>
A <a href="download.xml#Subversion" target="_top"><span style='white-space: nowrap'>subversion</span></a>
method
for downloading CppAD has been added.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The installation was broken on some systems because the
<a href="installunix.xml#Configure" target="_top"><span style='white-space: nowrap'>configure</span></a>
command tried to run
the <code><font color="blue">autoconf</font></code> and <code><font color="blue">automake</font></code> programs.
This has been fixed by adding
<code><font color="blue">AM_MAINTAINER_MODE</font></code> to the <code><font color="blue">autoconf</font></code> input file.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>Extend the
<a href="download.xml#Subversion" target="_top"><span style='white-space: nowrap'>subversion</span></a>
methods to include a full installation and old versions.
<br/>
<br/>
<b><big><a name="10-23" id="10-23">10-23</a></big></b>
<br/>
The <a href="installunix.xml#cxx_flags" target="_top"><span style='white-space: nowrap'>cxx_flags</span></a>
environment variable
has been changed from <code><font color="blue">CPP_ERROR_WARN</font></code> to <code><font color="blue">CXX_FLAGS</font></code>.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The command <code><font color="blue">configure --help</font></code> now prints a description
of the environment variables
<code><font color="blue">ADOLC_DIR</font></code>,
<code><font color="blue">FADBAD_DIR</font></code>,
<code><font color="blue">SACADO_DIR</font></code>,
<code><font color="blue">BOOST_DIR</font></code>,
and
<code><font color="blue">CXX_FLAGS</font></code>.
In addition, if the environment variables
<code><font color="blue">POSTFIX_DIR</font></code> or <code><font color="blue">CPP_ERROR_WARN</font></code> are used,
an message is printed saying that are not longer valid.
<br/>
<br/>
<b><big><a name="10-22" id="10-22">10-22</a></big></b>
<br/>
The correctness checks and speed test wrappers were moved
from the individual package directories to <a href="speed_main.xml" target="_top"><span style='white-space: nowrap'>speed_main</span></a>
.
This way they do not have to be reproduced for each package.
This makes it easier to add a new package,
but it requires the prototype for
<code><font color="blue"><span style='white-space: nowrap'>compute_</span></font><i><font color="black"><span style='white-space: nowrap'>test_name</span></font></i></code>
to be the same for all packages.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The <a href="http://trilinos.sandia.gov/packages/sacado/" target="_top"><span style='white-space: nowrap'>Sacado</span></a>
package was added to the list of <a href="speed.xml" target="_top"><span style='white-space: nowrap'>speed</span></a>
tests.
In addition, the discussion about how to run each of the
speed tests was corrected to include the
<code><i><font color="black"><span style='white-space: nowrap'>seed</span></font></i></code>
argument.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The
<code><i><font color="black"><span style='white-space: nowrap'>postfix_dir</span></font></i></code>
option
was removed on <a href="whats_new_06.xml#12-05" target="_top"><span style='white-space: nowrap'>2006-12-05</span></a>
but
it was not removed from the
<a href="installunix.xml#Configure" target="_top"><span style='white-space: nowrap'>configure</span></a>
documentation.
This has been fixed.
<code><span style='white-space: nowrap'><br/>
<br/>
</span></code>The routine <a href="checksimplevector.xml" target="_top"><span style='white-space: nowrap'>CheckSimpleVector</span></a>
was changed.
It used to require conversion of the form
<code><font color="blue"><span style='white-space: nowrap'><br/>
     </span></font><i><font color="black"><span style='white-space: nowrap'>Scalar</span></font></i><font color="blue"><span style='white-space: nowrap'>(</span></font><i><font color="black"><span style='white-space: nowrap'>i</span></font></i><font color="blue"><span style='white-space: nowrap'>)<br/>
</span></font></code>
where
<code><i><font color="black"><span style='white-space: nowrap'>i</span></font></i></code>
was <code><font color="blue">0</font></code> or <code><font color="blue">1</font></code>.
This does not work with when
<code><i><font color="black"><span style='white-space: nowrap'>Scalar</span></font></i></code>
is
<code><font color="blue">Sacado::Tay::Taylor<double></font></code>.
This requirement has been changed
(see <a href="checksimplevector.xml#Restrictions" target="_top"><span style='white-space: nowrap'>restrictions</span></a>
)
to support of
<code><font color="blue"><span style='white-space: nowrap'><br/>
     </span></font><i><font color="black"><span style='white-space: nowrap'>x</span></font></i><font color="blue"><span style='white-space: nowrap'> = </span></font><i><font color="black"><span style='white-space: nowrap'>i</span></font></i><font color="blue"><span style='white-space: nowrap'><br/>
</span></font></code>
where
<code><i><font color="black"><span style='white-space: nowrap'>x</span></font></i></code>
has type
<code><i><font color="black"><span style='white-space: nowrap'>Scalar</span></font></i></code>
