[fpc-devel] Building a debug version of FPC-main on Windows

[Werner Pamler]

I am using the following script to build a debug version of FPC-main on 
Windows:

set BINUTILS_DIR=C:\Lazarus\fpc_bootstrap_compiler\3.2.2\i386-win32
set BOOTSTRAP_COMPILER=%BINUTILS_DIR%\ppc386.exe
set FPC_DEST_DIR=c:\Lazarus\fpc-main
set BIN_DIR=bin\i386-win32
set FPC_BIN_DIR=%FPC_DEST_DIR%\%BIN_DIR%
set OPTIONS="-dDEBUG -gl -gw2"

::------------------------------------------------------------------------------
:: Set Path
::------------------------------------------------------------------------------
path %BINUTILS_DIR%;%PATH%

::------------------------------------------------------------------------------
:: Build FPC
::------------------------------------------------------------------------------
cd %FPC_DEST_DIR%
md %FPC_BIN_DIR%
copy %BINUTILS_DIR%\*.* %FPC_BIN_DIR%

make distclean
make install all OPT=%OPTIONS% INSTALL_PREFIX=%FPC_DEST_DIR% 
PP=%BOOTSTRAP_COMPILER%

::------------------------------------------------------------------------------
:: Make fpc.cfg,
::------------------------------------------------------------------------------
cd %FPC_DEST_DIR%
fpcmkcfg -d basepath=%FPC_DEST_DIR% -o %FPC_BIN_DIR%\fpc.cfg

This works fine for the first time when I apply it in a freshly cloned 
folder. But after having pulled a new version later, I does not work any 
more, it fails when the percentage counter of the installer is at 99% 
and when the command "make -C utils all" is to be executed, and when 
ptop.pp is compiled. The error message is "Can't find unit CustApp used 
by PtoP"

The error does not occur when I remove the OPT=%OPTIONS% from the make 
command line.

Does somebody have an idea what I am doing wrong?

Thanks.
