31 How to build ZLib.Ada under GNAT
|
Chris@4
|
32
|
Chris@4
|
33 You should have the ZLib library already build on your computer, before
|
Chris@4
|
34 building ZLib.Ada. Make the directory of ZLib.Ada sources current and
|
Chris@4
|
35 issue the command:
|
Chris@4
|
36
|
Chris@4
|
37 gnatmake test -largs -L<directory where libz.a is> -lz
|
Chris@4
|
38
|
Chris@4
|
39 Or use the GNAT project file build for GNAT 3.15 or later:
|
Chris@4
|
40
|
Chris@4
|
41 gnatmake -Pzlib.gpr -L<directory where libz.a is>
