Gnozal, can you email me your compiled exe for "quick and dirty command line zipper".
Thanks for all your trouble.
Paul.

Sure, but I lost your E-Mail address. Could you PM it ?

Just tried again on a clean build pc. Same result. I notice you are NT4 SP6 - could this explain the difference. I am on windows XP Pro SP2

With the exe's you sent through the CRCs match.

So this means that the MiniZIP source doesn't compile correctly on your machine ?

It is a very strange one!!!

On two seperate XP machines in fact. These are my compiler settings...

The CRC and path of Purebasic..
C:\Program Files\PureBasic4\purebasic.exe

CRC : 340aa5b3

CRC and Path for Purezip

C:\Program Files\PureBasic4\PureLibraries\UserLibraries\PureZIP

CRC : 861d3809

CRC of compiled EXE...
Yours: 104ac663
Mine: 757446ec

CRC of Example code (PureZIP_TEST_MiniZIP.pb) ...
99960cb9

I have compiled Minizip with PBIDE this time.

CRC wrote:; Generated by WIN-SFV32 v1.0
; (Compatible: Total Commander 6.54a)
MiniZIP.exe 6112F6E5

The jaPBe compiled EXE (the one I sent you) is different
offset $88 : E0 7C 8D for PBIDE
offset $88 : 30 78 89 for jaPBe
But, the generated archive is the same : no problem here.

Just Tried compiling under jaPBe. Still the same result! I wonder if it is a Windows XP issue? Have you tried compiling under XP?

Sorry, I don't have XP.

Very wise

I have just tried a third clean XP box & get exactly the same result. Using the very latest PB4 from the website & your PureZIP v1.30 from your homepage. Will have to throw out the gauntlet to other XP users to test.
Gnozal - thanks again for all the help.
PS do your purebasic program and purezip CRCs match mine?

Program : No !
PureZIP : Yes .

I just got your mail.
I compared your EXE and mine (same source compiled).
There is a difference :
- at offset 0B6C : 148 bytes are different
- before and after, it's identical !
And I confirm : if compacted with your EXE, the ZIP is valid but "Angry IP Scanner.exe" is missing the end of file (4096 bytes).

I can't explain this difference (same source, different EXE) !?
Maybe a PB bug ?

PS : did you get the latest beta libs (http://www.purebasic.com/beta) ?
It fixes some bugs, like the ReadFile()/Eof() bug.
