Installation order of Math.h++ and Tools.h++ is critical

Problem

---

For versions of Math.h++ prior to version 6.1.1 the installation order of Math.h++ and Tools.h++ is critical. This has been fixed in version 6.1.1 of Math.h++. Failure to do so in older versions of Math.h++ can result in errors such as:

>coreerr.cpp, line 67: Error: RWCORE_EOF(), returning const RWCatMsg* const , was previously declared returning const RWCatMsg*.
> coreerr.cpp, line 68: Error: RWCORE_GENERIC(), returning const RWCatMsg* const , was previously declared returning const RWCatMsg*.

Cause

---

Math.h++ can be purchased as a stand alone product without buying Tools.h++. However, Math.h++ does uses some classes from Tools.h++. This is possible because Math.h++ includes a very small subset of the files that come with Tools.h++. This is desirable for people using only Math.h++. Those using Tools.h++ with Math.h++ will face a dilemma because they share common header and source files. The common files in question that are part of the mathsrc directory are shown below:

 

   bstream.obj   coreerr.obj   mempool.obj   message.obj   pstream.obj
   ref.obj       rwerr.obj     rwfile.obj    utility.obj   vstream.obj

The header files corresponding to these source files are located in the rw directory.

If you are using Tools.h++ in conjunction with Math.h++, the question then becomes what is the version of the Tools.h++ files that came with Math.h++?

Math.h++ 5.1.3 comes with some Tools.h++ 6.1.0 files.
Math.h++ 5.2.0 comes with some Tools.h++ 7.0.1 files.
Math.h++ 6.0.0 comes with some Tools.h++ 7.0.1 files.
Math.h++ 6.1.0 comes with some Tools.h++ 7.0.1 files.

So how should Tools.h++ and Math.h++ be integrated together?

Action

---

The process of making sure Math.h++ works with Tools.h++ has two steps.

 

1. You must make sure the Tools.h++ header files in the rogue/rw directory are 100 percent consistent with your Tools.h++ installation by making sure you installed Tools.h++ AFTER Math.h++. If you have already installed Math.h++ on top of Tools.h++, you need to reinstall Tools.h++.
2. You must make sure you do not include the Tools.h++ source files that come with Math.h++ in the rogue/mathsrc directory in your Math.h++ library. To do this you must remove all references to the files listed above to the rogue/mathsrc makefile.
   • For the PC this can be done like this:

     # Tools.h++ objects
     #OBJ12 =    bstream.obj   coreerr.obj   mempool.obj   message.obj   pstream.obj
     #OBJ13 =    ref.obj       rwerr.obj     rwfile.obj    utility.obj   vstream.obj
     

   • For UNIX this can be done like this:

     #TOOLSOBJS= bstream.o   coreerr.o   mempool.o   message.o   pstream.o  #           ref.o       rwerr.o     rwfile.o    utility.o   vstream.o
     

3. Since you have removed the object files listed above from the Math.h++ library, you must effectively replace them by linking in the the Tools.h++ library when building an executable.

       CC -o myapp .... -lrwmth -lrwtool
   

    

4. Now recompile your Math.h++ and Tools.h++ libraries and rerun the examples.
