How to enable php-gmp on Mac OS X 10.6.6? (no macports)

无人久伴 提交于 2019-12-01 17:54:39
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 And it gave me this message: checking for GNU MP support... yes, shared checking for __gmp_randinit_lc

How to Install a C++ library on Windows for Dev-C++

I downloaded a library called GMP (it's for doing calculations with arbitrarily large numbers) and I can't figure out how to actually install and use it. All of the instructions I find tell me to run the files configure , MakeFile , and install , but when I try to do that I get 'install' is not a recognized internal or external command. All I can figure is that the instructions are for Linux, but I'm running Windows. I found a couple of instructions here on SO that tell me to copy certain files into the Dev-C++ folder, but I can't find the files specified. I've never had to install a library

I want to install the Rmpfr library of R, so I type within R: install.packages("Rmpfr") This package requires the GMP C library to be installed, which in Ubuntu can be installed typing on the terminal sudo apt-get install libgmp-dev So, after I try to install Rmpfr library in R, I receive an error message containing configure: error: GNU MP not found, or not 4.1.4 or up, see http://gmplib.org The problem is, I already have GNU MP installed, and its version is 5.1.2. So, something is wrong with me, maybe. Any clues? :-) Thanks! In my case it was solved by installation of libgmp3-dev $ sudo apt

How does GMP stores its integers, on an arbitrary number of bytes?

冷暖自知 提交于 2019-12-01 01:17:26
问题 2^64 is still far from the "infinity" my ram/hard drive can handle... First I wonder how GMP works with memory/processor since it does some kind of shady optimisations... I was also wondering if there is a way of storing an integer (unsigned, it's easier) on an arbitrary number of bytes. For example, on 50 bytes, I would have a cap of 2^400 -1. The thing to do is to work well with carries to keep the number consistent from one byte to another, I have some idea about that, but I'm really not

Arbitrary-Precision Math in PHP

一笑奈何 提交于 2019-11-30 17:48:55
I'm currently trying to figure out how to work with arbitrary-precision numbers in PHP. So I guess my first question would be what exactly is arbitrary-precision math. I tried Googling for a good definition but for some reason nobody can put it in simple enough words. Second, what are the differences between the BCMath and GMP libraries in PHP? I've heard claims that GMP's API is "fresher", but idk. Is one better? And my final question would be what type of numbers BCMath/GMP takes. Obviously it takes normal integers in string form (e.g. "5.34"), but I've seen implementations where BCMath

Installing GMP on Windows with cygwin

爱⌒轻易说出口 提交于 2019-11-30 16:43:17
I am new to C++ and I have to handle large integers, so I have to install GMP through Cygwin. Any documentation I can find on installing this already assumes that you know what you are talking about, and I really don't. Anyway, I got the right .tar or whatever, extracted it properly, and now any website I see says to run ./configure --prefix=${gmp_install} ... What in the world is gmp_install ? And what directory do I run configure from? Huh? I can run it from my little Cygwin terminal, but it just says no such file. Next, I am supposed to type make . From where? Help... Welcome to

Installing GMP on MacOS X with Xcode

I'm trying to use the GMP library in my C and C++ programs. I do code using the Xcode. I followed the instructions to install the GMP on my machine and I end up with a folder "~/usr/local/gmp-5.0.5" which contains the gmp.h file. How can I make my programs to see this library? if I decided to save my programs on desktop for example??? Where is the best place to install the gmp-5.0.5??? Using include "gmp.h" will show the error "file not found". I have done it this way: Download GMP from https://gmplib.org/ (gmp-6.0.0a.tar.lz) Download lzip from http://www.nongnu.org/lzip/lzip.html (lzip-1.16
