It should (intheory) port to other KAI C++ platforms (Cray, SGI, HP, Sun, Linux, Compaq)without difficulty. Since KAI C++ uses an EDG front end, other EDGfront-ended compilers (e.g. Comeau) should be able to compile Blitz++.</P><P>Recommended compile flags are:</P><P><TABLE><tr><td> </td><td class=example><pre>+K3 -O2 --restrict --abstract_pointer --abstract_float -tused</pre></td></tr></table></P><P>Note that you cannot compile with <CODE>-tall</CODE> (this will generate lots oferrors).</P><P>Under Linux, you may need the flag <CODE>-D__signed__=</CODE>. You should omit<CODE>-tused</CODE> since this template instantiation model is not supported by<CODE>gcc</CODE>, which is used as the back-end compiler.</P><P>Please note that since the purchase of KAI by Intel several years ago, the use of this compiler has been gradually phased out, with most of the KAIcompiler technology being transferred into the Intel C/C++ compiler. Thus,Blitz++ is no longer being routinely tested under <CODE>KCC</CODE>.</P><P><HR SIZE="6"><A NAME="SEC5"></A><TABLE CELLPADDING=1 CELLSPACING=1 BORDER=0><TR><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_1.html#SEC4"> < </A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_1.html#SEC6"> > </A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT"> <TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_1.html#SEC6"> << </A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_1.html#SEC3"> Up </A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_1.html#SEC18"> >> </A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT"> <TD VALIGN="MIDDLE" ALIGN="LEFT"> <TD VALIGN="MIDDLE" ALIGN="LEFT"> <TD VALIGN="MIDDLE" ALIGN="LEFT"> <TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz.html#SEC_Top">Top</A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_toc.html#SEC_Contents">Contents</A>]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[Index]</TD><TD VALIGN="MIDDLE" ALIGN="LEFT">[<A HREF="blitz_abt.html#SEC_About"> ? </A>]</TD></TR></TABLE><H3> 1.2.2 Intel C++ for x86 </H3><!--docid::SEC5::--><P>Blitz++ compiles under fairly recent versions of the Intel C++ compiler(version 7.1, 8.x or 9.0) for Linux platforms, as well as the comparable plug-in compiler for Windows that can be used within the Microsoft Visual Studio IDE.
