Compile/build guide?

[madderhatter]

I want to play around with some of the algorithms and understand the program better. Is there a build guide anywhere? I'm having so much difficulty. I have some building experience but this program has so many requirements it seems and no documentation I can find, I just run into one fault after another.

I would prefer to build the visual studio installation, but have also been trying to build the linux64 instance.

Which program ?

[madderhatter]

Prime95...I guess I accidently originally posted in a software section for other programs.

Moved to a more appropriate subforum.

Why try to build prime95 anew, when you can simply download it prebuilt for any of several common target OSes? https://www.mersenne.org/download/ I for one have been using prime95 since 1996 and never built it myself from source code, although I've built some of the other GIMPS apps repeatedly.

@OP: Welcome to the forum. Check out the GIMPS computing reference info compilation at https://mersenneforum.org/showthread.php?t=24607. Including https://www.mersenneforum.org/showpo...77&postcount=1 for why custom builds of prime95 are less desirable.

There are actually many reasons to do this.

Prove the code works. George encourages this.

To share... I find it a bit amazing how much everyone fights between people who are actually on the same side.

It is almost like many haven't read the prior art... And those who *have* read hope no one else has read...

I feel blessed being alive.

Well I want to play with the algorithms. I've done some math I want to try to study to maybe improve it to prove if my math is correct as well, as well as just study how the program works and allows for working with massive numbers and such. Also I like that it automatically reports if a new large prime is found right? If I'm able to adjust the algorithms to my math and my math is more efficient it will at once prove my math and prove my understanding. But stuck on this relatively simple stuff...because apparently there's no documentation I can find?

I'm stuck though I can't figure out the dependencies and libraries necessary. I encounter errors related to processor and definitions not being correct currently and no idea how to proceed in both visualstudio and linux.

My linux build attempts end with:

/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(gianthlp.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(cpuidhlp.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(ymult3a_core.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(ymult3ax.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(ymult3.o)' is incompatible with i386:x86-64 output
/usr/bin/ld: i386 architecture of input file `../gwnum/gwnum.a(ymult1ax_core.o)' is incompatible with i386:x86-64 output

ect, a huge error list...

And my visualstudio errors end with missing ; ) fatal errors.

Is your Linux operating system 64 bits? If so run make in the linux64 directory of the prime95 distribution -- I think that's the place!

I strongly recommend you start with the Pari/GP interpreter for prototyping your mathematical ideas. Then move onto learning to program C with the GMP library. Finally have a look at gwnum/gwnum.h and gwnum/giants.h with prime95 for FFT use. you might also like to look at OpenPFGW (sourceforge) which can test very large numbers for (probable) primality.

I have just given up with trying to compile mprime!

Yes, that's where I am. I get these errors after making the cwnum library and installing all the required libraries I can find, but there's something in the code that wants to use older like 486 architecture for some reason? or something? I don't understand these errors at all.

Yes I think the gmp libary is one of the requirements for building right, I looked at that already a bit.
