WPO

[Fiji]

How to generate WPO file for Whole Program Optimization. I am using FPC 2.7.1 on Windows.
The documentation is rather cryptic on this.

For example I get this error:
Project.dpr(96,1) Fatal: Cannot find "nm.exe" or "" to extract symbol liveness information from linked program


Thanks.

How did you install 2.7.1
nm.exe is part of the  lazarus installer (at least win32).

If you build yourself, you need to checkout those tools

http://svn.freepascal.org/svn/fpcbuild/trunk
http://svn.freepascal.org/svn/fpcbuild/trunk/install/binw32

It is not part of win64
http://svn.freepascal.org/svn/fpcbuild/trunk/install/binw64
No idea why.
