| 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.
|
|---|

|

| 36 |
|
|---|
| 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.
|
|---|
| 43 |
|
|---|
| 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.
