 After that, you need to compile the libraries. Do
 
-	cd libsrc
-	make clean atarilib
-	make clean c64lib
-	make clean c128lib
-	make clean plus4lib
-	make clean cbm610lib
-	make clean petlib

-Be sure to say "clean" each time, since some of the sources have a

+That's it! Installation directories for the RPM packages are
+
+	/usr/bin		for the binaries
+	/usr/lib/cc65/include	for include files
+	/usr/lib/cc65/lib	for libraries and startup files
+
+When using these directories, you don't need to set the CC65_INC and
+CC65_LIB environment variables. You may also use the /usr/local tree
+for installation, but the compiler and linker have no predefined search
+path for this directory, so you need the environment variables or
+change the search paths in the source.

+CC65 make facilities V0.3 for OS/2 by Mirco Miranda
+Date: 02/01/2000
+
+OS2HOWTO.TXT... I wrote this very fast... I hope that you can
+understand...
+
+Emx is a porting of gcc under OS/2. I wrote some C code that with
+simply (and few) preprocessor line can be compiled under OS/2 and Linux.
+Now for emx there are projects like P2 that let's add to OS/2 a complete
+Posix.1/SUS-like environment... I think that in the future the porting
+from bsd unix (and I hope linux) environment can be made very easy...
+
+These are the things because I tried to compile CC65 with emx/gcc...
+
+WARNING: at time that as wrote compiling with emx/gcc give some warnings.
+
+
+1. What do you need
+-------------------
+
+- emx/gcc 0.9D for OS/2
+
+http://hobbes.nmsu.edu/cgi-bin/h-browse?sh=1&dir=/pub/os2/dev/emx/v0.9d
+
+- gnu make
+
+http://hobbes.nmsu.edu/pub/os2/dev/util/gnumake.zip
+
+- bash
+
+Use (ba)sh coming with this package.
+There are many porting of unix shell for OS/2 and some don't
+work propely.
+
+- and finally the source package of the CC65
+  http://www.cc65.org/#Download
+  http://www.acc.umu.se/~arvid/cc65_mirror/cc65-sources-2.6.0.tar.gz
+
+I hope that's all! I have the complete emx/gnu tools installed on
+my OS/2 and I haven't test if you need other package. Sorry.
+
+
+2. Setup environment in OS/2
+----------------------------
+
+Unpack source package in a Directory and
+copy the files in src directory of source code.
+
+Install emx 0.9D following the istruction comes with it.
+Emx is well documented and I don't rewrite here emx documentation.
+
+Unpack the gnu make tool and copy make-os2.exe in ...\emx\gnu directory
+then rename it in make.exe
+
+Copy xxsh.exe in ...\emx\gnu directory
+
+
+If you want use my .cmd script (makeos2emx.cmd):
+
+- copy it in src directory
+- edit it and change the emx path(s) according with your(s).
+  (set MYEMXPATH=c:\appos2\emx)
+
+else
+
+- add ...\emx\gnu directory on your libpath
+- add ...\emx\gnu directiry on your path
+- set comspec=...\emx\gnu\xxsh.exe
+- run make -f make/gcc.mak in src directory
+- run make in libsrc directory
+
+3. My make files
+----------------
+
+If you use zap command, *.exe are not deleted.

+
+I haven't tested the generated code of cc65 executables with emx/gcc...
+If you use the cc65 executables compiled with emx/gcc to compile the library,
+please test it before hardly or productivity using.
+
+Safety solution is compile the cc65 executables with Watcom and then
+compile the library using gnu make and gnu (ba)sh coming with this package.
+If you use this last solution you must have only installed emx runtime because
+make.exe and xxsh.exe use it!
