# USE :

# Build groups must start with number 1 (no 0) without gaps between groups numbers.

# ************ Common parameters for all builds ************

# BASEDRV=          # Root base directory (usually your home directory), ie. ~
# FPCBASEDIR=       # root of freepascal fields (builds ans sources), ie. $BASEDRV/Sys/local/opt/fpc
# LOGDIR=           # logs directory, ie. $BASEDRV/Sys/Logs

# ************** GROUP ****************

# GROUPNAME[x]=       # Name of you build, ie. GROUPNAME[1]="Lazarus fixes"

# FPC parameters

# FPCNEWVERSION[x]=   # Freepascal version to build and to be used to build Lazarus, ie. =2.6.1
# FPCOLDVERSION[x]=   # Freepascal version used to build freepascal (i.e 2.4.5)
# SRCDIR[x]=          # Freepascal new version build directory, ie. $FPCBASEDIR/fpsrc/${FPCNEWVERSION[x]}
# PPCNAME[x]=         # Freepascal binary name (depends on architecture=, ie. ppcx64
# FPCSTART[x]=        # Absolute freepascal binary path used to build the ne one, ie.
#                         $BASEDRV/Sys/local/opt/fpc/${FPCOLDVERSION[x]}/bin/${PPCNAME[x]} 
#                         /usr/bin/$PPCNAME
# INSTALLDIR[x]=      # Directory used to build the new Freepascal version, ie. $FPCBASEDIR/${FPCNEWVERSION[x]}

# some random opts.

# OPTS[x]=            # Option to build freepascal, ie. -g- , -gl -dSAX_HTML_DEBUG -dUSE_MINGW_GDB
# COMMONOPTS[x]=

# COMMONOPTS[x]=UPXPROG=echo COPYTREE=echo OPT="${OPTS[x]}" GINSTALL=myinst.exe
#
# Some explanations:
#
# UPXPROG=echo   -> makes upxing a non-op. It is not needed in general with
# terabyte HDs on sale.
# UPXPROG=echo avoids UPXing of the resulting binaries, so that the FPC binaries 
# can be debugged. If you want as small FPC bins as possible, leave it away, 
# and add SMART=1 to both make lines. Note that UPXing wastes memory
# that is more expensive than disk. 
# 
# COPYTREE=echo  -> during install some example trees are recursively copied.
# this fails on SVN dirs. This omits those copies at the expense of no
# installed examples (you can still do that once in a while by exporting the
# source first, since the problem is in the SVN dirs).
# 
# INSTALL_PREFIX=d:\somedir  -> directory where to put snapshot
# 
# GINSTALL=vistin.exe  -> vistin is "ginstall.exe" copied to vistin.exe. This
# because Vista wants to UAC anything that is named "install" or "setup",
# which doesn't work for console apps.
# 
# The OPT= stuff is not fixed, but changes depending on my needs.

#  Lazarus variables 

# LAZSRCDIR[x]=     # Lazarus directory, ie. $BASEDRV/Sys/local/opt/lazarus_fixes_0_9_30
# OPTSLAZ[x]=       # Lazarus build options, ie. "-g- -O2 -CX -XX" , "-g- -O2 -CX -XX -Xs" # Check as -Xs use to prevent build
# LAZCONFDIR[x]=    # Lazarus config dir, ie. $BASEDRV/.lazarus-stable/ . If you run several lazarus versions, you have to run
                    # them with a different configuration directory with --pcp parameter (ie. --pcp=~/.lazarus-stable)
# SUPCONFDIR[x]=    # If you want to KEEP your configuration directory, you HAVE to set this to 0. If you want to start with a 
                    # clean build (like Lazarus trunk version), set it to 1
