[Scip] error extracting scip-3.2.0.tgz

Wed Jul 29 18:18:50 CEST 2015

For those interested, my question on the Apple StackExchange made for a particularly interesting discussion on how bsdtar differs from gnutar. Basically, there’s a fundamental difference in how gnutar packs duplicates compared to bsdtar. Check out https://apple.stackexchange.com/questions/197839/why-is-extracting-this-tgz-throwing-an-error-on-my-mac-but-not-on-linux for the entire discussion.

Thanks again to those that helped solve this problem.

Yes, exactly. That would make finding these errors a lot easier!

That’s a useful tidbit of information. I guess GNU tar just ignores errors like this, which I find a little worrisome. At least a warning should be raised when a malformed archive is encountered.

I also confirmed the same behavior on OSX.  It seems that it is the BSD tar in OSX that gives this error, whereas the same error is not reported by GNU tar.

I did find that 'gtar' would extract scip-3.2.0.tgz without complaining on OSX 10.10.  'gtar' can be installed using "brew install gnu-tar", if you are using homebrew.

Great! I was starting to wonder if I was crazy. Thanks very much.

Hi Geoffrey,

we just found the cause for the warning: there is a duplicate file in the archive (scip-3.2.0/applications/Coloring/Makefile).
We will fix this in a minute.

all the best

I’ve just using the built-in archive tool, and it gives me an error as well: http://i.imgur.com/3RcwFFw.png. I just scped the file to another Linux machine I have (running CentOS 6.6), and it extracted without error. This must be some oddity with the tar utility that comes with OS X. Does anyone else have an OS X machine that they can use to see if they get the same error? This is the first time I’ve ever had an issue extracting a tgz.

Dear Geoffrey,

our SHA-1 hash is the same. Have you tried some other tool to extract the files? The archive seems to be fine and we did not receive any similar issues by other users. This is strange.

all the best

I’m on OS X 10.10.4. tar --version gives me bsdtar 2.8.3 - libarchive 2.8.3. I’ve tried downloading with two browsers (Firefox and Safari) just to make sure it’s not a download error of some sort, and both browsers give me the same file. What’s your SHA-1 hash of scip-3.2.0.tgz? Mine is e085a4a3591eddf945dcb365d97d2512c267e374.

Hi,

a few seconds ago I used the same command and everything worked fine (with tar version 1.27.1). Which tar version and which operating system do you use?

Best regards,

Benny

I’m getting an error when I try to extract scip-3.2.0.tgz (both the standalone file and the one bundled in scipoptsuite-3.2.0.tgz). I’m attaching the output of tar -xvf scip-3.2.0.tgz to this email. The error I’m getting is this: tar: Error exit delayed from previous errors. I don’t see any other errors in the output. For what it’s worth, the older scip-3.1.1.tgz extracts without any error. I’m wondering if there’s just an error in the SCIP 3.2.0 package on the website.
