ZIP / UnZIP

[Makoto WATANABE]

I'd like to ZIP compression / decompression.
I think "ExtLibZip" is valid, but the example program becomes the error below.
http://www.freebasic.net/wiki/wikka.php?wakka=ExtLibZip

Please teach me how to fix it.

libzip.bas(27) error 58: Illegal specification, at parameter 1 (zip) of unpack_zip_file() in 'Private Sub unpack_zip_file(ByVal zip As zip Ptr, ByVal i As Integer)'

[fxm]

In the example, try to replace:

ByVal zip As zip Ptr
by:
ByVal zip As Any Ptr

Dim As zip_file Ptr fi
by:
Dim As Any Ptr fi

Dim As zip Ptr zip
by:
Dim As Any Ptr zip

A while ago I used zlib for this.
(I have not tried zip)
This will compress and decompress single files.
Drag and drop.

@dodicat,

libzip is also making use of zlib (under the hood).
However, it is extending the use to, e.g. managing existing archives ...
libzip/readme at NiH.at.

ExtLibZip → fxm [Update the example for compiling OK]

For the example, libzip.a for Win32 can be found here:
FB-win32-libzip-0.11.zip

Dear fxm

Thank you for updating the example.
I could compile the example program and unpack .zip.

P.S.
This example is .zip unpacking using libzip.
If someone adds examples of .zip compression using libzip to the document, beginners will become happier.

Hello ! When I try to compile the example, I get this error:

c:\fbc\1.05.0\bin\win32\ld.exe: cannot find -lz

I get also the same error when I try to compile the example provided by dodicat.

Have you the library file 'libz.a' (in ...\lib\win32\) ?

[Roland Chastain]

Have you the library file 'libz.a' (in ...\lib\win32\) ?

Thanks for your answer. No, I don't have that library.

You can get 'libz.a' at:

in file:

Thank you fxm. ;)

Dear fxm
Thanks for your quick response.
I am very happy.

By the way, I found another associated topic.

The example I added to the documentation is taken from the last post of this topic !
