# Building DLLs
# -------------
#  The commands below allow to build DLLs from the archive libraries.
#  From a libG4xxx.a, will extract the symbols with the genwindef tool,
#  which will produce a G4xxx.def file.
#  The G4xxx.def file will contain the list of symbols that are "exported"
#  or made public for using the DLLs.
#  The source genwindef.cc is in the geant4/config directory. The binary is
#  built during the library installation process, and will be placed in
#  $G4LIB/G4SYSTEM. 
#  If can also be built as follows :
#    DOS> cl.exe /Fegenwindef.exe genwindef.cc 
#  Then, to use it :
#    DOS> genwindef -o G4xxx.def -l G4xxx libG4xxx.a 
#  Libraries libG4xxx.lib can also be built with :
#    DOS> lib /def:G4xxx.def /out:libG4xxx.lib
#  It also produces a libG4xxx.exp used to build the DLL.
#  The DLL can be built with :
#    DOS> link /dll /out:G4xxx.dll libG4xxx.exp libG4xxx.a <dependencies>
#  Note that a DLL must be fully linked. You should NOT have undefined 
#  symbols as output of the link command.
