 Copy the file asio.h from Steinberg's ASIO SDK to the wineasio source
 directory.
 
-Due to a bug in winegcc, and the confusion regarding where 32bit wine dlls go
-on the various 64bit linux distributions,  I've hardcoded support for
-/usr/lib/wine and /usr/lib32/wine into the makefile.  If your distro uses
-another path edit the makefile and replace /usr/lib32/wine with the correct
-path.  Look at the last line of the makefile.  This wineasio should compile and
-install 32 bit wineasio on all 64 bit linux'.

+Wineasio by default uses 32 bit float as sample format (the native format used
 by Jack), if this causes a problem for an ASIO host, wineasio can be built to
 use 32 bit integer by defining the ASIOST32INT variable.  Do this by defining
 ASIOST32INT in the source code or by passing it as an argument to the compiler.
 
-To build, type (as a normal user): make
-To install, type (as root): make install
-To register the wineasio object, type (as a normal user): regsvr32 wineasio.dll
+Do the following to build for 32 bit Wine.
+# make clean
+# make
 
-The last command registers the ASIO COM object in the default prefix "~/.wine".
-If you use another prefix you will have to explicitly specify it,
-like "env WINEPREFIX=~/asioapp regsvr32 wineasio.dll"
+To install (substite with the path to the 32 bit wine libs for your distro).
+# sudo cp wineasio.dll.so /usr/lib32/wine/wineasio.dll.so 
+
+To build for 64bit Wine a shellscript has been added to modify asio.h and make
+it compatible with both 32 and 64bit Wine/Linux.  A separate Makefile has also
+been added for 64bit.
+
+Do the following to build for 64bit Wine.
+# ./prepare_64bit_asio
+# make clean
+# make -f Makefile64
+
+To install (substite with the path to the 64 bit wine libs for your distro).
+# sudo cp wineasio.dll.so /usr/lib/wine/wineasio.dll.so 
+
+Finally the dll must be registered in the wineprefix.
+For both 32 and 64 bit wine do:
+# regsvr32 wineasio.dll
+
+On a 64 bit system with wine supporting both 32 and 64 applications, regsrv32
+will register the 32 bit driver in a 64 bit prefix, use the following command
+to register the 64 bit driver in a 64 bit wineprefix:
+
+# wine64 regsvr32 wineaiso.dll
+
+regsvr32 registers the ASIO COM object in the default prefix "~/.wine".
+To use another prefix specify it explicitly, like:
+# env WINEPREFIX=~/asioapp regsvr32 wineasio.dll
