.Q.gz ?

[Angela]

Hi,

I can't get ".Q.gz"? https://code.kx.com/q/ref/dotq/#qgz-gzip

q).Q.gz

'.Q.gz

  [0]  .Q.gz

       ^

I'm on Ubuntu (wsl 2). I did install 32 bit zlib ("sudo apt-get install zlib1g-dev:i386") though I'm uncertain if I'm using the right one or setting it up correctly.

I also found this: https://github.com/lmartinking/qgz

But after compiling it, I get a run time error:  undefined symbol: inflateEnd

I would appreciate any thelp,

Thanks

Hi,

I sent an email before asking about .Q.gz I wanted to follow up on. (The email is not yet posted).

I was able to use the qgz library so I think that should suffice. 

I'm still not sure about .Q.gz from documentation. Is it only in 4.0 and not in 3.6? (Is this a general assumption from the error?)

q).Q.gz

'.Q.gz

  [0]  .Q.gz

       ^

Thanks!

Thanks, gotcha! Is there any where to check similar info? --I did do a quick check/search on the release pages. Or is it safe to assume this when I get the similar error/complaint?

thanks

[Charles Skelton]

we'll amend https://code.kx.com/q/ref/dotq/#qgz-gzip to note the version/release in which it became available.

We often document availability, e.g. https://code.kx.com/q/ref/dotq/#qbtoa-b64-encode

but clearly we're missing some.

thanks,

Charlie
