| ZLIB version 1.2.11 for OS/400 installation instructions | |
| 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 suppors 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 explicitely. | |
| Mainly for the reason above, always open zipped files in binary mode. |
