 BUILDING XSAMPLE from source
 ----------------------------
 
-The package should at least compile (and is tested) with the following compilers:
-
-pd - Windows:
--------------
-o Microsoft Visual C++ 6 or .NET command line: edit "config-pd-msvc.txt" and run "build-pd-msvc.bat"
-
-o BCC: edit "config-pd-bcc.txt" and run "build-pd-bcc.bat"
-
-o Cygwin GCC: edit "config-pd-cygwin.txt" and run "sh ./build-pd-cygwin.sh"
-> various versions of GCC die during compile with template optimization turned on 
-
-o MinGW: edit "config-pd-mingw.txt" and run "build-pd-mingw.bat"
-> MinGW binary folder must be included in the system path!
-
-pd - linux:
------------
-o GCC: edit "config-pd-linux.txt" and run "sh ./build-pd-linux.sh"
-> various versions of GCC die during compile with template optimization turned on 
-
-pd - OSX:

-o GCC: edit "config-pd-darwin.txt" and run "sh ./build-pd-darwin.sh"
-> various versions of GCC die during compile with template optimization turned on 
+You will need the flext C++ layer for PD and Max/MSP externals to compile this.
+See http://grrrr.org/ext/flext
+Download, install and compile the package.
+Afterwards you can proceed with building xsample.
 
-o XCode: use "xsample.xcode" project

+pd/Max - Windows - Microsoft Visual C, Borland C++, MinGW:

+Start a command shell with your eventual build environment
+(e.g. run vcvars32.bat for Microsoft Visual Studio)
 
-o Apple MPW-PR: edit & use the "flext.mpw" makefile
