APM library in command line utility

I'm working on a personal project that requires math to at least 200 significant digits. Believe it or not there is a huge difference between:

0.999999999999999999999^2e20 = 0.81873075307...
and
0.99999999999999999999^2e20 = 0.13533528323...

But double precision only recognizes
0.9999999999999999

I downloaded an arbitrary precision math package, MAPM. It has all the source code and header files, but dropping the load into the source folder and using #include <MAPM.H> in my application doesn't work.

I am sure it is just something I am missing. I don't know how to get Xcode to recognize the library for compiling.

Could someone explain how to do that.

Also, I am not married to MAPM if someone knows a simpler math package that is already installed in Xcode, perhaps.

Thank you so much for your help. Glad to see you are familiar with the library.

The makefile.osx is actually one more directory down.

85:downloads jerrywickey$ cd mapm495a
85:mapm495a jerrywickey$ cd unix_osx
85:unix_osx jerrywickey$ make -f makefile.osx

make: *** No rule to make target `mapmhasn.c', needed by `mapmhasn.o'. Stop.

Does this mean that makefile.osx is missing something?

Jerry

 

The terminal command and its results:

Code:

85:unix_osx jerrywickey$ make -f makefile.osx

make: *** No rule to make target `mapmhasn.c', needed by `mapmhasn.o'. Stop.

Mac OS 10.5.8
Xcode 3.1.3

Component versions
Xcode IDE: 1191.0
Xcode Core: 1192.0
ToolSupport: 1186.0

My download of MAPM includes a unix_OSX subdirectory. There is no file makefile.osx in the main directory. But there is such a file in the unix_osx directory.

I don't recall a check box labeled "Unix Development" but I installed Xcode a year ago.

The file is makefile.osx and a file makefile.unx in the unix_osx directory. I presume one is for unix and one for mac.

I downloaded MAPM today from the link:

Download the DOS / Win NT/9x distribution : mapm495a.zip


at the bottom of the page:

http://www.tc.umn.edu/~ringx004/mapm-main.html



But if you can point me to a download that worked for you, that's great!

Jerry

 

The downloaded from your link gets me past make -f

The file was make_osx.old

Code:

Make -f make_osx.old  

completed.

I dropped the files libmapm.a and m_apm.h into the source sub directory of my project and clicked "add" when asked and

Code:

#include <m_apm.h>

But on build I still get "No such file or directory"

I'm close. What stupid thing am I still doing wrong.

 

I don't intend to use unix. The only reason unix came up is because of the folder's name unix_osx.

I used the terminal command

Code:

Make -f make_osx.old

So unix shouldn't be an issue.

I tried all caps, all lc. I eyeballed the file name directly out of Xcode's groups and files. Some how the compiler isn't seeing the file.

Could you rehearse the procedure for linking a file to a project.

Jerry

 

Yup! thats it!

"" instead of <>

There are so many idiosyncrasies in modern compilers. (and they are just that: idiotic ) They are intended to make things more convenient, but at the same time everyone claims the more general the better. like i++ instead of i=i+1 even the use of an = sign instead of the more general set_g(g+1)

Ahhhh for the days of assembly language. I'm too old for this stuff.

Thanks very much.

Jerry

 

I don't know how old or young you are. C may be an oooooold language to you, but when I started, I had to hand compile 6502 mnemonic instructions to machine code. There were 176 instructions. This included all the flavors of load accumulator and bit wise shifts and rolls.

I'm old.

Familiarity isn't a test for idiosyncratic. Familiarity just makes it seem like it makes sense, whether it does or not. I am not uneducated in definitive disambiguation. I bet most of you young'ns didn't even know that programming in any language is simply a special case of definitive disambiguation.

Thank you for the help and check out my iPhone app. DNA Song

I don't know a 4004 but I do remember breaking my pencil point pushing micro switches to set page addresses.

Jerry

 

Yeah, well... wait till I tell you about holding my coffee in one hand, a big fat, sloppy pencil in the other and leaning over squinting at the board to find which switch direction is mark and set, because I am too lazy to go to the next room to get my glasses.

What could possibly go wrong?
