1b33c96954667ba382fa595baf7b31290bfdd517vboxsync ZLib for Ada thick binding (ZLib.Ada)
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync Release 1.3
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncZLib.Ada is a thick binding interface to the popular ZLib data
1b33c96954667ba382fa595baf7b31290bfdd517vboxsynccompression library, available at http://www.gzip.org/zlib/.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncIt provides Ada-style access to the ZLib C library.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync Here are the main changes since ZLib.Ada 1.2:
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Attension: ZLib.Read generic routine have a initialization requirement
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync for Read_Last parameter now. It is a bit incompartible with previous version,
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync but extends functionality, we could use new parameters Allow_Read_Some and
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Added Is_Open routines to ZLib and ZLib.Streams packages.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Add pragma Assert to check Stream_Element is 8 bit.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Fix extraction to buffer with exact known decompressed size. Error reported by
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync Steve Sangwine.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync computers. Patch provided by Pascal Obry.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Add Status_Error exception definition.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync- Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync How to build ZLib.Ada under GNAT
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncYou should have the ZLib library already build on your computer, before
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncbuilding ZLib.Ada. Make the directory of ZLib.Ada sources current and
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncissue the command:
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync gnatmake test -largs -L<directory where libz.a is> -lz
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncOr use the GNAT project file build for GNAT 3.15 or later:
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync1. Make a project with all *.ads and *.adb files from the distribution.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync2. Build the libz.a library from the ZLib C sources.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync4. Add the library z.lib to the project.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync5. Add the libc.lib library from the ObjectAda distribution to the project.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsync6. Build the executable using test.adb as a main procedure.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncThe source files test.adb and read.adb are small demo programs that show
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncthe main functionality of ZLib.Ada.
1b33c96954667ba382fa595baf7b31290bfdd517vboxsyncThe routines from the package specifications are commented.
