Hi all,

Since upgrading from BCB3 to BCB6 some time ago I have been getting the
following messages when building:

C++ warning: cannot create pre-compiled header: write failed
Linker error fatal: access violation: link terminated
Linker warning: unable to perform incremental link: performing full link

The project still builds and runs, but these messages are annoying - any
help appreciated.

I've got no magic bullet for this, but what's below seems ot have worked for
a couple of people.

Start the compiler with the -np command line option so it doesn't
automatically load a project.  If you start it by clicking an icon, right
click the icon and select Properties to get at the command line to insert
the -np

  Load the example project Wintools.bpr from the
  compiler's Examples\Wintools directory

  Do a Project|Build

If it gives the same problem:

  Shut down the IDE.

  Without any other programs running, run a scandisk
  (Win95/98) or chkdsk /f (NT,2K,XP) to detect and
  correct any possible file system problems.  You
  probably don't need to do the "low level" scandisk.
  If any bad blocks are found they will become files
  named filennnn.chk where nnnn is a number.  You
  can delete them to free up their disk space.

  Check that you've at least 30 Meg free on the
  drive which contains Windows and at least
  60 Meg free on each of the drive where you are
  developing the program and the drive where
  C++ Builder is located (they don't sum - if
  everything is on C: then make sure C: has
  at least 60 Meg free).

If it does not give the same problem:

  These settings are from BCB6 on my machine.
  Check that yours are the same:

  Under Project|Options|Compiler
    File_name $(BCB)\lib\vcl60.csm
    Cache_pre-compiled_headers  checked
    Stop_after combo box is empty

  Under Project|Options|Directories/Conditionals
    Include path $(BCB)\include;$(BCB)\include\vcl
    Library path $(BCB)\lib\obj;$(BCB)\lib

  Edit your project's *.BPR file while the IDE is not running.

    Look for empty paths, paths ending in \"  and paths
    which do not exist.  Correct any you find.

    Look for lib names with numbers that previous
    version numbers (for instance: vcl30.lib) which
    might have come over from the BCB3 project.

Check the path for the precompiled headers in the project path.  It is
possible the target directory (no longer) exists, especially if it was built
into the BCB 3 project file.
