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 https://code.mathr.co.uk/mandelbrot-symbolics.git
next edit
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 :
echo $LD_LIBRARY_PATH
result :
/home/a/opt/lib
or
export PATH=${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
then
git pull
Now install again

Note that the input format isn't checked, so bad input can give bad output !
Examples :
./m-binangle-to-rational
gives nothing:
- no output
- no errors

Bugs :
- "bug in the parsing of binary angles, it doesn't check for valid input, and bad input can give garbage values. "
