| 1 | ZLIB version 1.2.3 for AS400 installation instructions |
|---|
| 2 | |
|---|
| 3 | 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: |
|---|
| 65 | |
