You should install the development support files for zlib, try: sudo apt-get install libz-dev Other package names: zlib1g-dev. If you’ve already zlib library, make sure you’re compiling your code sources with -lz. See: missing zlib.h in ubuntu.
I couldn’t get request to work either, so ended up using http instead. var http = require(“http”), zlib = require(“zlib”); function getGzipped(url, callback) { // buffer to store the streamed decompression var buffer = []; http.get(url, function(res) { // pipe the response into the gunzip to decompress var gunzip = zlib.createGunzip(); res.pipe(gunzip); gunzip.on(‘data’, function(data) { … Read more
UPDATE: Browsers have been dropping support for raw deflate. zOompf has completed some very thorough research on this very topic here. Unfortunately, it appears that raw deflate is NOT safe to use. Check http://www.vervestudios.co/projects/compression-tests/results for more results. Here are the browsers that have been tested: /* Browser DEFLATE ZLIB */ XP Internet Explorer 6 PASS … Read more

If you want to use 8-bit strings instead of unicode string in sqlite3, set appropriate text_factory for sqlite connection: connection = sqlite3.connect(…) connection.text_factory = str
To decompress a gzip format file with zlib, call inflateInit2 with the windowBits parameter as 16+MAX_WBITS, like this: inflateInit2(&stream, 16+MAX_WBITS); If you don’t do this, zlib will complain about a bad stream format. By default, zlib creates streams with a zlib header, and on inflate does not recognise the different gzip header unless you tell … Read more
If you come across this question trying to install Ruby using Ruby Version Manager (RVM) on Ubuntu 10.04 then there are instructions on installing zlib on the rvm web site http://rvm.beginrescueend.com/packages/zlib/ The steps are: rvm pkg install zlib (or rvm package install zlib if you get “ERROR: Unrecognized command line argument: ‘pkg’” – older versions … Read more
Short form: .zip is an archive format using, usually, the Deflate compression method. The .gz gzip format is for single files, also using the Deflate compression method. Often gzip is used in combination with tar to make a compressed archive format, .tar.gz. The zlib library provides Deflate compression and decompression code for use by zip, … Read more
