[Ace-users] [ace-users] Large File Support with Solaris

[Steve Huston]

More particularly, from the NEWS file:

. Added ability to explicitly choose support for 32 bit or 64 bit file
  offsets on all platforms.  Define the _FILE_OFFSET_BITS preprocessor
  symbol to either 32 or 64 to choose the desired number of file
  offset bits.  This preprocessor symbol is supported natively by most
  UNIX and UNIX-like operating systems, and supported by ACE on
  Windows.  Use the new ACE_OFF_T typedef to refer to file offsets
  across UNIX and Windows portably.

Use this technique with the traditional build/configure mechanism, as
Johnny mentioned.
