ZLIB version 1.2.5.3 for AS400 installation instructions
|
|
|
|
I) From an AS400 *SAVF file:
|
|
|
|
1) Unpacking archive to an AS400 save file
|
|
|
|
On the AS400:
|
|
|
|
_ Create the ZLIB AS400 library:
|
|
|
|
CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
|
|
|
|
_ Create a work save file, for example:
|
|
|
|
CRTSAVF FILE(ZLIB/ZLIBSAVF)
|
|
|
|
On a PC connected to the target AS400:
|
|
|
|
_ Unpack the save file image to a PC file "ZLIBSAVF"
|
|
_ Upload this file into the save file on the AS400, for example
|
|
using ftp in BINARY mode.
|
|
|
|
|
|
2) Populating the ZLIB AS400 source library
|
|
|
|
On the AS400:
|
|
|
|
_ Extract the saved objects into the ZLIB AS400 library using:
|
|
|
|
RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
|
|
|
|
|
|
3) Customize installation:
|
|
|
|
_ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
|
|
according to the comments.
|
|
|
|
_ Compile this member with:
|
|
|
|
CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
|
|
|
|
|
|
4) Compile and generate the service program:
|
|
|
|
_ This can now be done by executing:
|
|
|
|
CALL PGM(ZLIB/COMPILE)
|
|
|
|
|
|
|
|
II) From the original source distribution:
|
|
|
|
1) On the AS400, create the source library:
|
|
|
|
CRTLIB LIB(ZLIB) TYPE(*PROD) TEXT('ZLIB compression API library')
|
|
|
|
2) Create the source files:
|
|
|
|
CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
|
|
CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
|
|
CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
|
|
|
|
3) From the machine hosting the distribution files, upload them (with
|
|
FTP in text mode, for example) according to the following table:
|

Notes: For AS400 ILE RPG programmers, a /copy member defining the ZLIB

API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC).

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.
