minizip lib

[jamba]

this is great! thanks ts-soft.

A couple of questions...
what language is your minizip.lib written in? C?
Also, in the event you no longer support this would you release the source to the lib?

[ts-soft]

The source for the static lib is here available.
The PureBasic Source to use this static lib is in the downloadpackage.

Hello,

Is there a library for linux which is something like this?

Thanks.

I have come back to a project to make changes, it was originally done in an earlier version of PB - using the latest, I get:

POLINK: error: Unresolved external symbol 'SYS_AllocateString'.
POLINK: error: Unresolved external symbol 'PB_CallFunctionFast2'.
POLINK: fatal error: 2 unresolved external(s).

any ideas? or is the lib not compatible with 4.61?

[ts-soft]

Use the includefile, the userlib is not up to date!
Or use tailbite to create a userlib.

Thanks! That did it.

Update

fixed examples static lib not found

I tried this to add a folder

Code: Select all

IncludePath "..\"
XIncludeFile "minizip_include.pbi"

Define.s zip
zip = "H:\ABC\test.zip"

Define ff = ZIP_FileCreate(zip.s)
If ff
  ZIP_DirAdd(ff,"H:\ABC\ABC\",#Z_DEFAULT_COMPRESSION,0)
  ZIP_FileClose(ff)
EndIf

But i get "division by zero forbidden".

Any advice?

[ts-soft]

You are using the latest version as include?
The debugger doesn't show the line with division by zero?
The dir for packing is empty?

Okay, i have added blind some sanitycheck, please download the latest version.

Greetings - Thomas

Since purebasic has "lost" some important zip functionality (e.g. adding a file to a packed file), I searched for an alternative - and minizip looks really good (thank you, Thomas).

I would recommend to update the pbi file to be usable for the latest versions of Purebasic, I changed the three CRC32Fingerprint() and CRC32FileFingerprint() calls and added the following lines to the code...

Code: Select all

	:
	CompilerIf #PB_Compiler_Version<540

		Macro Fingerprint(source,size,dummy)
			CRC32Fingerprint(source,size)
		EndMacro
		Macro FileFingerprint(file,dummy)
			CRC32FileFingerprint(file)
		EndMacro

	CompilerElse
		UseCRC32Fingerprint()

	CompilerEndIf

	:

	result= ... #Z_DEFLATED,Compression,0,15,8,0,ZIP_Password,FileFingerprint(Filename,#PB_Cipher_CRC32))
	result= ... #Z_DEFLATED,Compression,0,15,8,0,ZIP_Password,FileFingerprint(ZIP_FileList(),#PB_Cipher_CRC32))
	result= ... #Z_DEFLATED,Compression,0,15,8,0,ZIP_Password,Fingerprint(*source,sourceLen,#PB_Cipher_CRC32))
