I have run across some trouble trying to compile Aliqueit for a 64-bit installation of Ubuntu. This is in reference to my page on the steps to create an Ubuntu Aliqueit system with ggnfs, msieve, YAFU and associated scripts, etc.

The machine info:
[code]
AMD Athlon(tm) 64 X2 Dual Core Processor 4000+
2G memory
Linux math11 3.2.0-31-generic #50-Ubuntu SMP Fri Sep 7 16:16:45 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
[/code]I have successfully compiled and installed gmp (per instructions, I uninstalled all gmp and libgmp repository packages first), gmp-ecm, msieve and YAFU. But, Aliqueit seems to be missing something from the gmp library:

No luck...

My memory must be really short term - a few posts back is the same trouble mentioned by Mr. Odd and solved in my earlier versions by adding libgmp3-dev via the repository. I'm also trying the procedure you put forth in [URL="http://www.mersenneforum.org/showpost.php?p=300091&postcount=424"]post 424[/URL], but that isn't working either.:sad:

Thanks for helping sort this out.

My last general comment would be that I compiled GMP 5.0.4 from source, because IIRC the repositories weren't working either. If you're using an older Ubuntu, it's possible that whatever you have installed doesn't have the necessary functions, and that self-compiling a newer GMP might work.

Edit: Perhaps try adding "-static"? I don't know why it's failing, you've pointed the linker to libgmp, and used "-lgmp", so that should be it... unless the mentioned functions aren't in that particular gmp version, like I hypothesized above.

That's the rub. I got the latest everything from the gmp(5.0.5) and ecm(6.4.3b) sites and compiled via their instructions. I gave up on trying to use the repositories and even had to remove some repository versions of packages so that gmp and ecm were "happy." So, if something is missing, they removed it from their latest versions, or it isn't showing up in my system via the methods of compile I used.

Thinking more about it, this might be the trouble. I used their "impatient procedure" to compile, so maybe there is a switch/option I need to engage that isn't invoked by default. However, I expected your procedure from post 424 would have taken care of it.

I do see the defines in gmp.h:
[code]
#define mpz_clear __gmpz_clear
__GMP_DECLSPEC void mpz_clear __GMP_PROTO ((mpz_ptr));
[/code]but, not where __gmpz_clear is defined, probably in a library.

Thanks again...

Yeah, I never figured this out either. If you do, please let us know and/or post a binary!

I wish I'd known that. Since I saw no further posts, I "assumed" (erroneously) that you were up and running. Sorry!

I do need to track this down to some resolution so I can update my "Steps..." page.

The conclusion will be posted here...

By the way: libgmp3-dev is a transitional package for smooth upgrades.

Like I've said more than once before, my binary is available [URL="https://sites.google.com/site/bbuhrow/home/aliquot-sequences"]here[/URL]. That's Aliqueit compiled on Ubuntu 11.04, gcc 4.5.2, GMP 5.0.4.

@Dubslow: Thanks, again. I may have to take that route (even, if just for now), but I am still in question as to why... BTW, I did try -static.

@Ralf Recker: Thanks also. Unfortunately I'm not versed enough to see why my setup differs from yours. Here (with paths adjusted) are my outputs:
