ZLIB version 1.3.2 for OS/400 installation instructions |

|
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 supports 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. |

|
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. |
|

|
Please read comments in this member for more information. |

|
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 explicitly. |
|
47
|
|
|
48
|
Mainly for the reason above, always open zipped files in binary mode. |
