I have successfully found a wrapper for GZIP using LZW compression, but I could only manage to compile it as a console application the way you can see it in the included files.
If I want to add the same source and header to my GUI application, it doesn't find <iostream>. I don't know why, since it is able to compile as console application in a different project.
Does anyone know why it fails to compile as GUI?
I think that an expert could make a QT-compliant wrapper easily from it. I failed to do this, since I'm a newbie, and the compile error is:
In file included from ..\NESA\gzstream.c:29:
..\NESA/gzstream.h:34:20: error: iostream: No such file or directory
..\NESA/gzstream.h:35:19: error: fstream: No such file or directory
In file included from ..\NESA\gzstream.c:29:
..\NESA/gzstream.h:46: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'gzstreambuf'
..\NESA/gzstream.h:75: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'gzstreambase'

..\NESA/gzstream.h:104: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'ogzstream'
...etc...
The only difference between .pro files is:
Console project:
QT += core
QT -= gui
TARGET = gzstream
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
GUI project:
QT += core gui xml
TARGET = NESA
TEMPLATE = app
The working combination is here (so others can also use it to uncompress .z files), but somehow it adds additional line breaks for some reason:

Added after 4 minutes:
ZLIB is also needed for this wrapper, so maybe ZLIB does support .Z files too, not just deflation in .ZIP files, but yet I'm too weak to find out how I could use it without a wrapper.
Added after 9 minutes:
Is there something (e.g. a switch) included in its makefile of the original project which why it is able to use <iostream>?
