1 ZLIB version 1.2.11 for OS/400 installation instructions 2 31) 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, 7else you have to unpack first to some directory on a system supporting it, 8then move the whole directory to the IFS via the network (via SMB or FTP). 9 102) Edit the configuration parameters in the compilation script. 11 12 EDTF STMF('/path/to/the/zlib/ifs/source/directory/os400/make.sh') 13 14Tune the parameters according to your needs if not matching the defaults. 15Save the file and exit after edition. 16 173) Enter qshell, then work in the zlib OS/400 specific directory. 18 19 QSH 20 cd /path/to/the/zlib/ifs/source/directory/os400 21 224) Compile and install 23 24 sh make.sh 25 26The 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 34That's all. 35 36 37Notes: 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. 49
