<H3> 1.2.7 Cray T3E/Cray T90/Cray C90/Cray J90 </H3>
<!--docid::SEC10::-->
<P>

As of Version 0.2-alpha-02 of Blitz++, Version 3.0.0.0 of the Cray C++
compiler is supported (well, tolerated anyway).  It seems to be based on an
older version of the EDG front end, so some kludges are required.  It
doesn't support partial ordering of member templates, so slicing arrays
requires the workaround described in Section <A HREF="blitz_2.html#SEC49">2.4.4 Slicing</A>.  Portions
of the standard library are missing, such as <CODE>&#60;limits&#62;</CODE>,
<CODE>&#60;complex&#62;</CODE>, and <CODE>&#60;set&#62;</CODE>.  This means you won't be able to use
complex numbers (well, not the ISO/ANSI C++ versions anyway), numeric
inquiry functions, or fast traversal orders.
</P><P>

These compilation flags are recommended:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>-h instantiate=used
</pre></td></tr></table></P><P>

For optimization, you'll want:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>-O3 -h aggress
</pre></td></tr></table></P><P>

The ability of the Cray C++ compiler to optimize away temporary objects is
disappointing.  It's not able to optimize away expression templates overhead
or comma-delimited array initializers.  Please note that support for compiling
Blitz++ under the Cray C++ compiler is no longer being actively maintained.

<P>

To download the Blitz++ library, go to the Blitz++ download page, at

</P><P>

But please read the section on supported platforms and compilers first.

Blitz++ uses <FONT SIZE="-1">GNU</FONT> Autoconf, which handles rewriting Makefiles for various
platforms and compilers.  It has greatly simplified installation and
porting.  Many thanks for John W. Eaton and Brendan Kehoe for their help
with this.
</P><P>

To install blitz, unpack the <TT>`blitz-VERSION.tar.gz'</TT> file (it will
install into a subdirectory <TT>`blitz-VERSION'</TT>).  For example:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>[tveldhui@n2001:~] 32: ls -l blitz*.gz
-rw-r--r--   1 tveldhui users      480953 Jun 23 15:20 blitz-0.5.tar.gz
[tveldhui@n2001:~] 33: gunzip blitz-0.5.tar.gz 
[tveldhui@n2001:~] 34: tar xvf blitz-0.5.tar
blitz-0.5/CHANGELOG
blitz-0.5/COPYING
blitz-0.5/INSTALL
blitz-0.5/Makefile.in
blitz-0.5/README
blitz-0.5/THANKS
  .
  .
</pre></td></tr></table></P><P>

Then go into the main blitz directory, and type:
</P><P>

<A NAME="IDX4"></A>
<TABLE><tr><td>&nbsp;</td><td class=example><pre>./configure CXX=[compiler]
</pre></td></tr></table></P><P>

where [compiler] is one of <CODE>xlc++</CODE>, <CODE>icpc</CODE>, <CODE>xlC</CODE>, <CODE>cxx</CODE>, 
<CODE>aCC</CODE>, <CODE>CC</CODE>, <CODE>g++</CODE>, <CODE>KCC</CODE>, <CODE>pgCC</CODE> or <CODE>FCC</CODE>.
</P><P>

You can also specify special command-line options for your compiler, using
this syntax:
</P><P>

<TABLE><tr><td>&nbsp;</td><td class=example><pre>./configure CXX=g++ CXXFLAGS="-ftemplate-depth-50"
</pre></td></tr></table></P><P>

If you are interested in benchmarking, you may want to use the option
<CODE>--with-blas=...</CODE> to specify the path where the blas library is found.
Run the configure script with the option <CODE>--help</CODE> to see all the 
available options.
</P><P>

Once the configure script is done, you can do any of these things:
</P><P>

<DL COMPACT>
<DT><CODE>make lib</CODE>
<DD>Check the compiler and create <TT>`libblitz.a'</TT>.
<P>

<DT><CODE>make check-testsuite</CODE>
<DD>Make the blitz library plus build and run the testsuite.
<P>

<DT><CODE>make check-examples</CODE>
<DD>Make the blitz library plus build and run the examples.
<P>

<DT><CODE>make check-benchmarks</CODE>
<DD>Make the blitz library plus build and run the benchmarks.
<P>

<DT><CODE>make all</CODE>
<DD>Do all of the above.  This may take a <STRONG>long</STRONG> time.
<P>

<DT><CODE>make install</CODE>
<DD>Build the blitz library and documentation and install, along with the
blitz header files, in prefix directory.
</DL>
<P>

Building the benchmark programs requires both a Fortran 77 and Fortran 90
compiler.
