Using mathgl from C and C++ - Raspberry Pi Forums

-

i'm trying make heating controller based on raspbarian pi. want give web interface users can see graphs of heat store , other temperatures, , going producing graphs .png files using mathgl.

i've done "apt-get install mathgl" seemed work, tried compile following example mathgl web site.

#include <mgl2/mgl.h>
int main()
{
mglgraph gr;
gr.fplot("sin(pi*x)");
gr.writeframe("test.png");
}

compilation fails because included header file can't found.

turns out there no mgl2 directory or mgl.h file anywhere on pi. need install other packages use mathgl c , c++ ?

has been successful in using mathgl on pi ? know google indicated there problems mathgl , python.

many thanks, j/.

you have downloaded utilities , examples. search available mathgl packages use
apt-cache search mathgl
.

code: select all

pi@raspberrypi ~ $ apt-cache search mathgl libmgl-dev - library scientific graphs. (development files) libmgl-fltk5 - library scientific graphs. (fltk runtime library) libmgl-glut5 - library scientific graphs. (glut runtime library) libmgl-qt5 - library scientific graphs. (qt runtime library) libmgl-wx5 - library scientific graphs. (wxwidgets runtime library) libmgl5 - library scientific graphs. (main runtime library) mathgl - library scientific graphs. (utlities , examples) mathgl-doc-en - library scientific graphs. (english documentation) mathgl-doc-ru - library scientific graphs. (russian documentation) python-mathgl - library scientific graphs. (python module) udav - application data visualization based on mathgl
can see need install libmgl-dev package development code.

p.s. post, have never heard of mathgl, looking package nice line graphs. examples pretty me.

hmm... ok appears mathgl version 1 not 2. need install <mgl/mgl.h>

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
