I tried to make something with FMOD, and first I only put in "uses"
section fmod. When I tried to compile this I got error:
/usr/bin/../lib/libfmod.so: undefined reference to `__divdi3'.
What is this? How to solve this?
I use UBUNTU710 and Lazarus 0.9.24

I have that same problem, my code for test:

Code: [Select]program test;
uses
  fmod;
var
  _mod: pointer;
  c: char;
begin
  //    INITIALIZE
  if not(FSOUND_Init(32000, 64, 0)) then begin
    exit;
  end;
  // LOAD SONG
  _mod:= FMUSIC_LoadSong('invtro94.s3m');
  FMUSIC_PlaySong(_mod);
  writeln('Playing %s...\n'+FMUSIC_GetName(_mod));
  c:='s';
  while(c<>'a') do begin
    read(c);
  end;
  //FREE SONG AND SHUT DOWN
  FMUSIC_FreeSong(_mod);
  FSOUND_Close();
end.

Compiling return error: /usr/lib/libfmod.so: undefined reference to
`__divdi3`
......

SOLUTION:
Code: [Select]program teste;
//--- INSERT THIS----------
{$linklib stdc++}
//--- INSERT THIS----------
uses
  fmod;
...

Compiling return: Success!!

I think that linking libstc++ is overkill for that. This symbol is
normally located in libgcc, so {$linklib gcc} should be enough.
