gmp

I'm trying to make a cross compiler with the files from http://crossgcc.rts-software.org/doku.php?id=i386linuxgccformac I'm on an Intel Mac (10.6.6, x86_64) I compiled: gmp, mpfr, mpc for the cross compiler as 32bit (as I'm on a 64bit Mac) but I'm getting ld: warning: option -s is obsolete and being ignored ld: warning: ignoring file /gmp1/lib/libmpc.dylib, file was built for unsupported file format which is not the architecture being linked (i386) ld: warning: ignoring file /gmp1/lib/libmpfr.dylib, file was built for unsupported file format which is not the architecture being linked (i386) ld

How can I calculate the n-th root of an integer using PHP/GMP? Although I found a function called gmp_root(a, nth) in the PHP source , it seems that this function has not been published in any release yet*: http://3v4l.org/8FjU7 *) 5.6.0alpha2 being the most recent one at the time of writing ComFreek Original source: Calculating Nth root with bcmath in PHP – thanks and credits to HamZa ! I've rewritten the code to use GMP instead of BCMath: function gmp_nth_root($num, $n) { if ($n < 1) return 0; // we want positive exponents if ($num <= 0) return 0; // we want positive numbers if ($num < 2)

Having only used the GNU MP Bignum Library a few times, I was interested to see that the way I had previously allocated/initiated arrays is now obsolete. From Integer Special Functions : 5.16 Special Functions The functions in this section are for various special purposes. Most applications will not need them. — Function: void mpz_array_init (mpz_t integer_array, mp_size_t array_size, mp_size_t fixed_num_bits) This is an obsolete function. Do not use it. This is how I would allocate and initialze an array of mpz_t . int array_size = 100; mpz_t *num_arr; num_arr = malloc(arr_size * sizeof(mpz_t

I've just discovered, to my embarrassment, that feeding negative exponents to mpz_pow_ui doesn't work very well. ("The manual does say unsigned long, you know.") For the other mpz_pow functions, the manual uses concepts I don't understand. For example " base ^ exp mod mod " in the following: void mpz_powm (mpz_t rop, mpz_t base, mpz_t exp, mpz_t mod) void mpz_powm_ui (mpz_t rop, mpz_t base, unsigned long int exp, mpz_t mod) Set _rop_ to _base_^_exp_ mod _mod_. Negative exp is supported if an inverse base-1 mod mod exists (see mpz_invert in Section 5.9 [Number Theoretic Functions], page 35). If

I have some code that uses libgmp. At some point the user may request a factorial of a very large number. Unfortunately, this results in libgmp raising an abort signal. For example the following code: #include <cmath> #include <gmp.h> #include <iostream> int main() { mpz_t result; mpz_init(result); mpz_fac_ui(result, 20922789888000); std::cout << mpz_get_si(result) << std::endl; } Results in: $ ./test gmp: overflow in mpz type Aborted Apparently, the number produced is REALLY big. Is there anyway to handle the error more gracefully than an abort. This is a GUI based application and it aborting

I'm installing a modern version of gcc on solaris. I compiled gmp, mpfr and mpc, they're all 64bit. When I try to configure gcc as follows I get an error complaining that mpc,mpfr and gmp are the wrong elf class. What gives? ./../gcc-4.5.1/configure --prefix=/opt/OurAppDir/gcc --with-gmp=/opt/OurAppDir/gmp --with-mpfr=/opt/OurAppDir/mpfr --with-gnu-as --with-gnu-ld --build=sparc-sun-solaris2.10 checking build system type... sparc-sun-solaris2.10 checking host system type... sparc-sun-solaris2.10 checking target system type... sparc-sun-solaris2.10 checking for a BSD-compatible install... ./..

I need to use GMP in an iphone program I'm working on, but don't really know where to begin. I know that I have to build a version for the device and a version for the simulator, but that is as much as I know. I've tried looking around but haven't been able to find much. Has anyone here successfully build GMP for iphone that would care to guide me through the process? I saw Building GMP for iOS but it is not working for me. I thought I had built it successfully using: ./configure CC="/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/llvm-gcc-4.2" CXX="/Developer/Platforms
