1 ZLIB version 1.2.11 for OS/400 installation instructions
|

|
|
|
3 1) Download and unpack the zlib tarball to some IFS directory.
|
|
|
4 (i.e.: /path/to/the/zlib/ifs/source/directory)
|
|
|
5
|
|
|
6 If the installed IFS command suppors gzip format, this is straightforward,
|
|
|
7 else you have to unpack first to some directory on a system supporting it,
|
|
|
8 then move the whole directory to the IFS via the network (via SMB or FTP).
|
|
|
9
|
|
|
10 2) Edit the configuration parameters in the compilation script.
|
|
|
11
|
|
|
12 EDTF STMF('/path/to/the/zlib/ifs/source/directory/os400/make.sh')
|
|
|
13
|
|
|
14 Tune the parameters according to your needs if not matching the defaults.
|
|
|
15 Save the file and exit after edition.
|
|
|
16
|
|
|
17 3) Enter qshell, then work in the zlib OS/400 specific directory.
|
|
|
18
|
|
|
19 QSH
|
|
|
20 cd /path/to/the/zlib/ifs/source/directory/os400
|
|
|
21
|
|
|
22 4) Compile and install
|
|
|
23
|
|
|
24 sh make.sh
|
|
|
25
|
|
|
26 The script will:
|
|
|
27 - create the libraries, objects and IFS directories for the zlib environment,
|
|
|
28 - compile all modules,
|
|
|
29 - create a service program,
|
|
|
30 - create a static and a dynamic binding directory,
|
|
|
31 - install header files for C/C++ and for ILE/RPG, both for compilation in
|
|
|
32 DB2 and IFS environments.
|
|
|
33
|
|
|
34 That's all.

|
37 Notes: For OS/400 ILE RPG programmers, a /copy member defining the ZLIB
|
|
|
38 API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
|
|
|
39 In the ILE environment, the same definitions are available from
|
|
|
40 file zlib.inc located in the same IFS include directory as the
|
|
|
41 C/C++ header files.
|
|
|
42 Please read comments in this member for more information.

|
|
|
44 Remember that most foreign textual data are ASCII coded: this
|
|
|
45 implementation does not handle conversion from/to ASCII, so
|
|
|
46 text data code conversions must be done explicitely.
|
|
|
47
|
|
|
48 Mainly for the reason above, always open zipped files in binary mode.
