问题 I've downloaded the GMP multiprecision library and I compiled without errors the following code through the terminal with the gcc main.c -lgmp command but I can't figure out how to include the GMP library in XCode 4.5 because the howtos online are a bit confusing. I really need to use the GMP library for my projects and any comment would be great help. #include <stdio.h> #include <gmp.h> int main(int argc, const char * argv[]) { printf("Hello, World!\n"); mpz_t a; return 0; } 回答1: (Answered

问题 I downloaded GCC 4.5 from http://www.netgull.com/gcc/releases/gcc-4.5.0/ but when I try to setup / build I am getting below error: Linux:>~/shared_scripts/bin/gcc/gcc-4.5.0 1040> /x/home/prakash_satya/shared_scripts/bin/gcc/gcc-4.5.0/configure CC="gcc -m64" --prefix=/x/home/prakash_satya/shared_scripts/bin/gcc/gcc-4.5.0 --with-gmp-lib=/usr/lib64 --with-mpfr-lib=/usr/lib64 --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++ checking build

问题 In R, Int64 whole numbers can not be accurately serialized to and from JSON, because existing JSON libraries will coerce the value into a numeric, or expect to represent the number in scientific notation. Does anyone know of a way to accurately serialize and deserialize whole Int64 numbers to/from JSON with precision, or is a library modification (probably to RJSONIO) required? The full story, including libraries I have tried so far, and the gacky workarounds necessary for the interim: >

问题 I'm attempting to build GnuTLS on Mac OS X 10.5 (Leopard) Server (yeah, I know, it's a bit dated, but that's what this server is running at the moment) and am running into an issue building Nettle: I've built & installed GMP, but Nettle's configure cannot find it. I built & installed GMP 5.0.2 as follows (the GCC version solution is from here): curl -O ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2 tar xjf gmp-5.0.2.tar.bz2 pushd gmp-5.0.2 CC=gcc-4.2 CXX=g++4.2 ./configure --prefix=/usr

问题 Is there a way to serialize a GMP rational number in binary form? I only see functions for reading/writing to a FILE , but even there it is a text form. I could convert to numerator/denominator and use the integer functions, but again there only a FILE output is available. I need to be able to get the raw bytes or write to a C++ stream. 回答1: I think you were looking for mpz_inp_raw mpz_out_raw (doc: https://gmplib.org/manual/I_002fO-of-Integers.html) Full demo: #include <cstdio> #include

问题 I use a libgmp (GMP) to work with very long integers, stored as mpz_t : http://gmplib.org/manual/Integer-Internals.html#Integer-Internals mpz_t variables represent integers using sign and magnitude, in space dynamically allocated and reallocated. So I think mpz_t is like pointer. How can I send an array of mpz_t variables with data over MPI? 回答1: Use mpz_import() and mpz_export() to convert between mpz_t and e.g. char arrays, which you can then send/receive over MPI. Be careful with getting

问题 Is there any way to use PHP GMP Functions on windows without using a virtual machine? Thanks in advance. [http://php.net/manual/en/ref.gmp.ph] 回答1: According to GMP's website: GMP's main target platforms are Unix-type systems, such as GNU/Linux, Solaris, HP-UX, Mac OS X/Darwin, BSD, AIX, etc. It also is known to work on Windows in both 32-bit and 64-bit mode. Also try to uncomment ;extension=php_gmp.dll in php.ini Hope it works! 回答2: Now, in XAMPP that uses PHP 7.2.4 comment has another

问题 I want to enable my php-gmp and I don't want to use macports because I use homebrew. First I brew install gmp and I got gmp 5.0.1 Then I downloaded the PHP source 5.3.6, then I go to source/ext/gmp I did phpize and then MACOSX_DEPLOYMENT_TARGET=10.6 CFLAGS='-O3 -fno-common -arch i386 -arch x86_64' LDFLAGS='-O3 -arch i386 -arch x86_64' CXXFLAGS='-O3 -fno-common -arch i386 -arch x86_64' ./configure --with-php-config=/Developer/SDKs/MacOSX10.6.sdk/usr/bin/php-config; make -j6;sudo make install
