|
|
|
|
|
|
|
1) Download and unpack the zlib tarball to some IFS directory.
|
|
|
|
|
(i.e.: /path/to/the/zlib/ifs/source/directory)
|
|
|
|
|
|
|
|
|
|
If the installed IFS command supports gzip format, this is straightforward,
|
|
|
|
|
else you have to unpack first to some directory on a system supporting it,
|
|
|
|
|
then move the whole directory to the IFS via the network (via SMB or FTP).
|
|
|
|
|
|
|
|
|
|
2) Edit the configuration parameters in the compilation script.
|
|
|
|
|
|
|
|
|
|
EDTF STMF('/path/to/the/zlib/ifs/source/directory/os400/make.sh')
|
|
|
|
|
|
|
|
|
|
Tune the parameters according to your needs if not matching the defaults.
|
|
|
|
|
Save the file and exit after edition.
|
|
|
|
|
|
|
|
|
|
3) Enter qshell, then work in the zlib OS/400 specific directory.
|
|
|
|
|
|
|
|
|
|
QSH
|
|
|
|
|
cd /path/to/the/zlib/ifs/source/directory/os400
|
|
|
|
|
|
|
|
|
|
4) Compile and install
|
|
|
|
|
|
|
|
|
|
sh make.sh
|
|
|
|
|
|
|
|
|
|
The script will:
|
|
|
|
|
- create the libraries, objects and IFS directories for the zlib environment,
|
|
|
|
|
- compile all modules,
|
|
|
|
|
- create a service program,
|
|
|
|
|
- create a static and a dynamic binding directory,
|
|
|
|
|
- install header files for C/C++ and for ILE/RPG, both for compilation in
|
|
|
|
|
DB2 and IFS environments.
|
|
|
|
|
|
|
|
|
|
That's all.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Notes: For OS/400 ILE RPG programmers, a /copy member defining the ZLIB
|
|
|
|
|
API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).
|
|
|
|
|
In the ILE environment, the same definitions are available from
|
|
|
|
|
file zlib.inc located in the same IFS include directory as the
|
|
|
|
|
C/C++ header files.
|
|

Please read comments in this member for more information.

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