I have a CGI application in C that creates an html page by saving a char* as a html page: void saveTextFile(const char *filename, const char *str){.......} called as saveTextFile("..\\index.html",outputFile); How do I use zlib to take as input the "outputFile" char array and output a zipped html page with appropriate headers? Wo...
Hi, I am using a slightly modified version of the DotZlib which is part of the contrib directory with the zlib source code to inflate a realtime data stream. Instead of the regular inflateInit I need to use InflateInit2 - but this the only difference to the provided library. Netherlesse after a couple of reads I receive error code 1 fr...

Hi I'm trying to unzip a Zip archive in PHP using extractTo. The PHP script is running via the webbrowser i.e. as "nobody". The script: 1) creates a new subdirectory (e.g. "abc"), with permissions 0777 and owner "nobody" under document root (i.e. one level above public_html) 2) copies the Zip file (from an incoming FTP directory und...
I'm trying to use the zlib extension in ActiveTcl 8.5 in order to save out a compressed blob to a file. Both ActiveTcl 8.5.5 and 8.5.6 on win32 have a zlibtcl 1.2.3 extension. I've tried both: package require zlibtcl and load zlibtcl123.dll Which both seem to indicate that the extension is properly loaded. However, I can't seem ...
I'm creating something that includes a file upload service of sorts, and I need to store data compressed with zlib's compress() function. I send it across the internet already compressed, but I need to know the uncompressed file size on the remote server. Is there any way I can figure out this information without uncompress()ing the data...
When installing a gem on my system, I get the following error: gem install blackbook --version ">= 1.0.7" --source http://github.com/tamoyal/blackbook/tree/master ERROR: While executing gem ...

I've been chasing a very mysterious bug for days now, which seems to revolve around the (ZLIB library); it occurs once every month or so, and only on some specific production environments. Here is what the code does: The program calls gzopen to write to a file X. The program writes data to the file, doing several gzwrite. The program f...
I am upgrading a app to Delphi 2009. The app uses Soap and we compress the soap request and response streams using Zlib. This works fine in Delphi 2006 but not in Delphi 2009. So I went back to Delphi 2006 and changed to use FastZlib. It all worked fine in Delphi2006 but does not work in Delphi 2009 and I get Decompress errors. Has any...

Hi all, Im trying to compile z/lib on z/OS USS(thats right a mainframe). ive got gmake and the c89 compiler (which im assuming is c89 standards compliant) and USS is supposed to be POSIX compliant. But zlib seems to be tripping up on struct internal_state FAR *state; /* not visible by applications */ with the following error(s) c8...
I am interfacing with a server that requires that data sent to it is compressed with Deflate algorithm (Huffman encoding + LZ77) and also sends data that I need to Inflate. I know that Python includes Zlib, and that the C libraries in Zlib support calls to Inflate and Deflate, but these apparently are not provided by the Python Zlib m...
I'm writing a PHP script that generates gzipped files. The approach I've been using is to build up a string in PHP and gzcompress() the string before writing it out to a file at the end of the script. Now I'm testing my script with larger files and running into memory allocation errors. It seems that the result string is becoming too la...
Hey guys, I'm working on a commercial project that requires a couple of files to be bundled (packed) into an archive and then compressed. Right now we have zlib in our utility library, but it doesn't look like zlib has the functionality to compress multiple files into one archive. Anyone know of free libraries I'd be able to use for thi...
I am creating a C++ program that will read a .docx's plain text. My plan of attack is to rename the .docx as a .zip and then unzip. I then will rename the .xml file containing the text of the document as a .txt and parse it out. Right now I have figured out the renaming which was easy enough. I am now struggling with unzipping. I am...
The Ruby on Rails website recommends installing Ruby from source under Linux. I encountered a number of C library problems building ruby from source on a clean install of Unbuntu 9. All the instructions I found on the net about installing ruby on ubuntu have involved using the prepackaged (.deb-based) ruby. Clearly this isn't what the r...
Can I uncompress a bytestream that was compressed using the .NET GZipStream using the zlib library in C++? ...
Okay so I have some data streams compressed by python's (2.6) zlib.compress() function. When I try to decompress them, some of them won't decompress (zlib error -5, which seems to be a "buffer error", no idea what to make of that). At first, I thought I was done, but I realized that all the ones I couldn't decompress started with 0x78DA ...
I am trying to compress data using the zlib .net library. Regardless of the content of the uncompressed string I only seem to get two bytes of data in the raw[]. { string uncompressed = "1234567890"; byte[] data = UTF8Encoding.Default.GetBytes(uncompressed); MemoryStream input = new MemoryStream(data); MemoryStream out...
