|
+ First Implementation 10 Sept 2000 Armin Diehl
|
|
|
+
|
|
|
+ Currently generating NetWare-NLM's only work under Linux. This is
|
|
|
+ because nlmconf from binutils does not work with i.e. win32 coff
|
|
|
+ object files. It works fine with ELF-Objects.
|
|
|
+
|
|
|
+ The following compiler-swiches are supported for NetWare:
|
|
|
+ $DESCRIPTION : NLM-Description, will be displayed at load-time
|
|
|
+ $M : For Stack-Size, Heap-Size will be ignored
|
|
|
+ $VERSION x.x.x : Sets Major, Minor and Revision
|
|
|
+
|
|
|
+ Sorry, Displaying copyright does not work with nlmconv from gnu bunutils.
|
|
|
+
|
|
|
+ Exports will be handled like in win32:
|
|
|
+ procedure bla;
|
|
|
+ begin
|
|
|
+ end;
|
|
|
+
|
|
|
+ exports bla name 'bla';
|
|
|
+
|
|
|
+ Without Name 'bla' this will be exported in upper-case.
|
|
|
+
|
|
|
+ The path to the import-Files (from netware-sdk, see developer.novell.com)
|
|
|
+ must be specified by the library-path. All external modules are defined
|
|
|
+ as autoload.
|
|
|
+
|
|
|
+ i.e. Procedure ConsolePrintf (p:pchar); cdecl; external 'clib.nlm';
|
|
|
+ sets IMPORT @clib.imp and MODULE clib.
|
|
|
+
|
|
|
+ If you dont have nlmconv, compile gnu-binutils with
|
|
|
+ ./configure --enable-targets=i386-linux,i386-netware
|
|
|
+ make all
|
|
|
+
|
|
|
+ Debugging is currently only possible at assembler level with nwdbg, written
|
|
|
+ by Jan Beulich. Nwdbg supports symbols but it's not a source-level
|
|
|
+ debugger. You can get nwdbg from developer.novell.com. To enter the
|
|
|
+ debugger from your program, define "EnterDebugger" as external cdecl and
|
|
|
+ call it. Int3 will not work with Netware 5.
|
|
|
+
|
|
|
+ A sample program:
|
|
|
+
|
|
|
+ Program Hello;
|
|
|
+ (*$DESCRIPTION HelloWorldNlm*)
|
|
|
+ (*$VERSION 1.2.2*)
|
|
|
+ (*$M 8192,8192*)
|
|
|
+ begin
|
|
|
+ writeLn ('hello world');
|
|
|
+ end.
|
|
|
+
|
|
|
+ compile with:
|
|
|
+ ppc386 -Tnetware hello
|
|
|
+
|
|
|
+ ToDo:
|
|
|
+ - No duplicate imports and autoloads
|
|
|
+ - Screen and Thread-Names
