Title: how to compile "help.cxx" ?
Post by: quanpin on April 17, 2012, 09:31:55 PM

1. I try to complie fltk_projects ,but can't compile the "help.cxx" file.

Code: [Select]

tc@box:~$ fltk-config --compile help.cxx
g++ -march=i486 -mtune=i686 -Os -pipe -D_THREAD_SAFE -D_REENTRANT -o help help.cxx /usr/lib/libfltk.a -lpthread -ldl -lm -lXext -lX11
/tmp/ccNuwGGI.o: In function `main':
help.cxx:(.text.startup+0x29): undefined reference to `Fl_Help_Dialog::Fl_Help_Dialog()'
help.cxx:(.text.startup+0x43): undefined reference to `Fl_Help_Dialog::load(char const*)'
help.cxx:(.text.startup+0x4d): undefined reference to `Fl_Help_Dialog::textsize(unsigned char)'
help.cxx:(.text.startup+0x59): undefined reference to `Fl_Help_Dialog::show(int, char**)'
help.cxx:(.text.startup+0x6e): undefined reference to `Fl_Help_Dialog::~Fl_Help_Dialog()'
collect2: ld returned 1 exit status
tc@box:~$
and I compiled it in ubuntu also like this.

2 . the other cxx file can compiled , but the exefile are more bigger than tc's . like
use "  fltk-config --compile editor.cxx "
the "editor" is 375.55KB ,  but  the TC's  is 14404 B , Why it's  more bigger than TC.

thankx

I can't find my notes for help.xx, but does something of this form do the trick:

Code: [Select]

g++ -march=i486 -mtune=i686 -Os -pipe -fno-exceptions -fno-rtti -fpic -L/usr/lib -lfltk -lfltk_images -lfltk_forms -lpng -o mnttool mnttool.cxx

I try to run "strip editor" , the exefile size from 375.55KB change to 291.91KB.   but the tc's 14.07KB.

Code: [Select]

tc@box:~$ fltk-config --compile editor.cxx
g++ -march=i486 -mtune=i686 -Os -pipe -D_THREAD_SAFE -D_REENTRANT -o editor editor.cxx /usr/lib/libfltk.a -lpthread -ldl -lm -lXext -lX11
tc@box:~$ strip editor

2.  And the help.cxx code

Code: [Select]

#include <FL/Fl_Help_Dialog.H>
#include <iostream>
using namespace std;


//
// 'main()' - Display the help GUI...
//

int // O - Exit status
main(int  argc, // I - Number of command-line arguments
     char *argv[]) // I - Command-line arguments
{
  Fl_Help_Dialog *help; // Help dialog


  help = new Fl_Help_Dialog;

  if (argc < 2)
    help->load("/usr/share/doc/tc/help.html");
  else
    help->load(argv[1]);

  help->textsize(15);
  help->show(1, argv);

  Fl::run();

  delete help;

  return (0);
}


//
// End of "$Id: help.cxx 5519 2006-10-11 03:12:15Z mike $".
//
