| ZLib for Ada thick binding (ZLib.Ada) | |
| Release 1.3 | |
| ZLib.Ada is a thick binding interface to the popular ZLib data | |
| compression library, available at http://www.gzip.org/zlib/. | |
| It provides Ada-style access to the ZLib C library. | |
| Here are the main changes since ZLib.Ada 1.2: | |
| - Attension: ZLib.Read generic routine have a initialization requirement | |
| for Read_Last parameter now. It is a bit incompartible with previous version, | |
| but extends functionality, we could use new parameters Allow_Read_Some and | |
| Flush now. | |
| - Added Is_Open routines to ZLib and ZLib.Streams packages. | |
| - Add pragma Assert to check Stream_Element is 8 bit. | |
| - Fix extraction to buffer with exact known decompressed size. Error reported by | |
| Steve Sangwine. | |
| - Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits | |
| computers. Patch provided by Pascal Obry. | |
| - Add Status_Error exception definition. | |
| - Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit. | |
| How to build ZLib.Ada under GNAT | |
| You should have the ZLib library already build on your computer, before | |
| building ZLib.Ada. Make the directory of ZLib.Ada sources current and | |
| issue the command: | |
| gnatmake test -largs -L<directory where libz.a is> -lz | |
| Or use the GNAT project file build for GNAT 3.15 or later: | |
| gnatmake -Pzlib.gpr -L<directory where libz.a is> | |
| How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2 | |
| 1. Make a project with all *.ads and *.adb files from the distribution. | |
| 2. Build the libz.a library from the ZLib C sources. | |
| 3. Rename libz.a to z.lib. | |
| 4. Add the library z.lib to the project. | |
| 5. Add the libc.lib library from the ObjectAda distribution to the project. | |
| 6. Build the executable using test.adb as a main procedure. | |
| How to use ZLib.Ada | |
| The source files test.adb and read.adb are small demo programs that show | |
| the main functionality of ZLib.Ada. | |
| The routines from the package specifications are commented. | |
