Question

Im trying to get gnuplot up running for C++ environment in XCode.

Im using following tutorial to archieve my result:
http://www.calozgroup.org/Shulabh/MediaWikiS/index.php5?title=Gnuplot_in_C%2B%2B_using_XCode

• I have created the libgnuplot.a and imported this along with the gnuplot_i.h into my project.

• Copied /opt/local/bin/gnuplot into /usr/local/bin

• I have created the ~/MacOSX/environment.plist file with following content:

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DT$
  <plist version="1.0">
  <dict>
          <key>GNUTERM</key>
          <string>aqua</string>
          <key>PATH</key>
          <string>/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin</string>
  </dict>
  </plist>
  

The error occurs when compiling following sample code:

char myStr[] = "text";
char myEqu[] = "sin(x)";

gnuplot_ctrl *h;
h = gnuplot_init();
gnuplot_plot_equation(h, myEqu, myStr);
gnuplot_close(h);

Error:

cannot find gnuplot in your PATH(lldb) 

Furthermore i was getting following compiler warnings:

Conversion from string literal to 'char *' is deprecated

gnuplot_setstyle(handle, "lines");

I tried to modify these to:

char line_string[] = "lines";
gnuplot_setstyle(handle, line_string);

Answer 1

I reinstalled gnuplot and it suddenly worked.
