| [1096] | 1 | ZLib for Ada thick binding (ZLib.Ada)
|
|---|
| 2 | Release 1.3
|
|---|
| 3 |
|
|---|
| 4 | ZLib.Ada is a thick binding interface to the popular ZLib data
|
|---|
| 5 | compression library, available at http://www.gzip.org/zlib/.
|
|---|
| 6 | It provides Ada-style access to the ZLib C library.
|
|---|
| 7 |
|
|---|
| 8 |
|
|---|
| 9 | Here are the main changes since ZLib.Ada 1.2:
|
|---|
| 10 |
|
|---|
| 11 | - Attension: ZLib.Read generic routine have a initialization requirement
|
|---|
| 12 | for Read_Last parameter now. It is a bit incompartible with previous version,
|
|---|
| 13 | but extends functionality, we could use new parameters Allow_Read_Some and
|
|---|
| 14 | Flush now.
|
|---|
| 15 |
|
|---|
| 16 | - Added Is_Open routines to ZLib and ZLib.Streams packages.
|
|---|
| 17 |
|
|---|
| 18 | - Add pragma Assert to check Stream_Element is 8 bit.
|
|---|
| 19 |
|
|---|
| 20 | - Fix extraction to buffer with exact known decompressed size. Error reported by
|
|---|
| 21 | Steve Sangwine.
|
|---|
| 22 |
|
|---|
| 23 | - Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
|
|---|
| 24 | computers. Patch provided by Pascal Obry.
|
|---|
| 25 |
|
|---|
| 26 | - Add Status_Error exception definition.
|
|---|
| 27 |
|
|---|

| 31 | How to build ZLib.Ada under GNAT
|
|---|
| 32 |
|
|---|
| 33 | You should have the ZLib library already build on your computer, before
|
|---|
| 34 | building ZLib.Ada. Make the directory of ZLib.Ada sources current and
|
|---|
| 35 | issue the command:
|
|---|
| 36 |
|
|---|
| 37 | gnatmake test -largs -L<directory where libz.a is> -lz
|
|---|
| 38 |
|
|---|
| 39 | Or use the GNAT project file build for GNAT 3.15 or later:
|
|---|
| 40 |
|
|---|
| 41 | gnatmake -Pzlib.gpr -L<directory where libz.a is>

| 44 | How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
|
|---|
| 45 |
|
|---|
| 46 | 1. Make a project with all *.ads and *.adb files from the distribution.
|
|---|
| 47 | 2. Build the libz.a library from the ZLib C sources.
|
|---|
| 48 | 3. Rename libz.a to z.lib.
|
|---|
| 49 | 4. Add the library z.lib to the project.
|
|---|
| 50 | 5. Add the libc.lib library from the ObjectAda distribution to the project.
|
|---|
| 51 | 6. Build the executable using test.adb as a main procedure.

|
|---|
| 54 | How to use ZLib.Ada
|
|---|
| 55 |
|
|---|
| 56 | The source files test.adb and read.adb are small demo programs that show
|
|---|
| 57 | the main functionality of ZLib.Ada.
|
|---|
| 58 |
|
|---|
| 59 | The routines from the package specifications are commented.
