|
|
I) From an AS400 *SAVF file:
|
| 4 |
|
|
|
| 5 |
|
|
1) Unpacking archive to an AS400 save file
|
| 6 |
|
|
|
| 7 |
|
|
On the AS400:
|
| 8 |
|
|
|
| 9 |
|
|
_ Create the ZLIB AS400 library:
|
| 10 |
|
|
|
| 11 |
|
|
CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
|
| 12 |
|
|
|
| 13 |
|
|
_ Create a work save file, for example:
|
| 14 |
|
|
|
| 15 |
|
|
CRTSAVF FILE(ZLIB/ZLIBSAVF)
|
| 16 |
|
|
|
| 17 |
|
|
On a PC connected to the target AS400:
|
| 18 |
|
|
|
| 19 |
|
|
_ Unpack the save file image to a PC file "ZLIBSAVF"
|
| 20 |
|
|
_ Upload this file into the save file on the AS400, for example
|
| 21 |
|
|
using ftp in BINARY mode.
|
| 22 |
|
|
|
| 23 |
|
|
|
| 24 |
|
|
2) Populating the ZLIB AS400 source library
|
| 25 |
|
|
|
| 26 |
|
|
On the AS400:
|
| 27 |
|
|
|
| 28 |
|
|
_ Extract the saved objects into the ZLIB AS400 library using:
|
| 29 |
|
|
|
| 30 |
|
|
RSTOBJ OBJ(*ALL) SAVLIB(ZLIB) DEV(*SAVF) SAVF(ZLIB/ZLIBSAVF) RSTLIB(ZLIB)
|
| 31 |
|
|
|
| 32 |
|
|
|
| 33 |
|
|
3) Customize installation:
|
| 34 |
|
|
|
| 35 |
|
|
_ Edit CL member ZLIB/TOOLS(COMPILE) and change parameters if needed,
|
| 36 |
|
|
according to the comments.
|
| 37 |
|
|
|
| 38 |
|
|
_ Compile this member with:
|
| 39 |
|
|
|
| 40 |
|
|
CRTCLPGM PGM(ZLIB/COMPILE) SRCFILE(ZLIB/TOOLS) SRCMBR(COMPILE)
|
| 41 |
|
|
|
| 42 |
|
|
|
| 43 |
|
|
4) Compile and generate the service program:
|
| 44 |
|
|
|
| 45 |
|
|
_ This can now be done by executing:
|
| 46 |
|
|
|
| 47 |
|
|
CALL PGM(ZLIB/COMPILE)
|
| 48 |
|
|
|
| 49 |
|
|
|
| 50 |
|
|
|
| 51 |
|
|
II) From the original source distribution:
|
| 52 |
|
|
|
| 53 |
|
|
1) On the AS400, create the source library:
|
| 54 |
|
|
|
| 55 |
|
|
CRTLIB LIB(ZLIB) TYPE(PROD) TEXT('ZLIB compression API library')
|
| 56 |
|
|
|
| 57 |
|
|
2) Create the source files:
|
| 58 |
|
|
|
| 59 |
|
|
CRTSRCPF FILE(ZLIB/SOURCES) RCDLEN(112) TEXT('ZLIB library modules')
|
| 60 |
|
|
CRTSRCPF FILE(ZLIB/H) RCDLEN(112) TEXT('ZLIB library includes')
|
| 61 |
|
|
CRTSRCPF FILE(ZLIB/TOOLS) RCDLEN(112) TEXT('ZLIB library control utilities')
|
| 62 |
|
|
|
| 63 |
|
|
3) From the machine hosting the distribution files, upload them (with
|
| 64 |
|
|
FTP in text mode, for example) according to the following table:
|

Remember that most foreign textual data are ASCII coded: this
|
| 108 |
|
|
implementation does not handle conversion from/to ASCII, so
|
| 109 |
|
|
text data code conversions must be done explicitely.
