There was aproblem with the library utility in version 2.0 which is now fixed. Youwill need to use the large or 32 bit flat model. If you are not debugging,turn off theoptions that collect debugging information. Make sure you don't runBorland's exceptions and my simulated exceptions at the same time.<P>If you are using version 5 remember to edit include.h to deactivate my Booleanclass.<P>When running my test program with Borland 4.5 under ms-dos you may run out ofmemory. Either compile the test routine to run under <I>easywin</I> or usesimulated exceptions rather than the built in exceptions. Under <I>easywin</I>the test program indicates a memory leak. I presume this is partly because ofthe way windows organises its heap rather than there being a real problem.<P>If you can, upgrade to windows 95 or window NT and use the 32 bit consolemodel.<P>If you are using the 16 bit large model, don't forget to keep all matricesless than 64K bytes in length (90x90 for a rectangular matrix if you areusing <TT>double</TT> as your element type). Otherwise your program willcrash without warning or explanation.You may need to break the <A HREF="testing.html">tmt</A> set of testfiles into two parts to get the program to fit into your computer. <P>In version 4.5, under <I>easywin</I> the automaticclean-up of objects bythe exception mechanism does not seem to work correctly.Use my simulated exceptions ifthis is a problem.<P>One version of Borland had DBL_MIN incorrectly defined. If youare using an older version of Borland and are getting strangenumerical errors in the test programs reinstate the commented outstatements in precision.h.<P>I include make files that work under Borland 4.5 and 5. You will needto edit these to correctly locate the directories for the include andlibrary files. Both assume you are using simulated exceptions. <TT>BC.MAK</TT>also works with version 3.1 if you delete the options that are not recognisedand the reference tothe library file that is not recognised.<P><A HREF="gcc.html"> next</A> - <A HREF="gcc.html"> skip</A> - <A HREF="compiler.html"> up</A> - <A HREF="index.html"> start</A><P></BODY></HTML>⌨️ 快捷键说明
