Install edit

"you need to "make install" mandelbrot-symbolics lib before trying anything with mandelbrot-numerics"

Dependencies edit

  pkg-config --version

#include <stdbool.h>
#include <stdlib.h>
#include <gmp.h>
#include <pari/pari.h>
 gcc -shared -ggdb  -std=c99 -Wall -Wextra -pedantic -fPIC -O3 -pipe -ggdb -MMD -I../include -c  -lpari -lmpc -lmpfr -lgmp -lm

clone edit

git clone

To install library to local prefix ~/opt/lib ~/opt/bin and so on:

make -C mandelbrot-symbolics/c/lib prefix=${HOME}/opt install
make -C mandelbrot-symbolics/c/bin prefix=${HOME}/opt install

then to run do:

 export LD_LIBRARY_PATH=${HOME}/opt/lib

check :


result :



 export PATH=${HOME}/opt/bin:${PATH}

check :

  echo $PATH

then the programs can be run like

 m-binangle-from-rational 1/2

no manual path specification necessary

To set it permanently change file .profile[1]

sudo gedit ~/.profile

update edit

git edit

From console opened in the mandelbrot-numerics directory :

 git pull

If you made some local changes you can undu them :

 git checkout -f


 git pull

Now install again

m-binangle-to-rational edit

from console

 ./m-binangle-to-rational ".(001)"

result :


Note that the input format isn't checked, so bad input can give bad output !

Examples :


gives nothing:

  • no output
  • no errors
 ./m-binangle-to-rational 0.(001001001001001001001001001001001001001001001001001001001001001001001001010)

gives bash error :

 bash: błąd składni przy nieoczekiwanym znaczniku `('
./m-binangle-to-rational "0.(001001001001001001001001001001001001001001001001001001001001001001001001010)"

gives floating point error
