Can't find installed QT4 when using 'make .... xconfig' command

Vel.

Ahh I see, thank you so much SGaist. Sorry I'm so new to this, how do I add the folder containing qmake to my PATH variable? (sorry for the dublicate question I thought I deleted the other one)

I see my qmake is in this directory:

/Developer/Tools/Qt/qmake

I looked at these links but not too sure:
http://doc.qt.io/qt-4.8/qmake-variable-reference.html
http://doc.qt.io/qt-4.8/qmake-environment-reference.html

SGaist

It's not qmake related it's bash configuration.

PATH=$PATH:/Developer/Tools/Qt/

Thank you, I'll keep looking cause I did that and re-started my computer and same error :((

SGaist

That line doesn't change PATH permanently, just for the current terminal until you close it.

Vel.

Right, sorry I did that too. and this is what I got ..... hmm I installed from here https://download.qt.io/archive/qt/4.8/4.8.5/ both qt-mac-opensource-4.8.5.dmg && qt-mac-opensource-4.8.5-debug-libs.dmg

Are you sure that qmake is there ? what does ls -la /Developers/Tools/Qt return ?

Vel.

@SGaist said:

ls -la /Developers/Tools/Qt

That's a good point you have. I checked and got the following below... seems like it's executable and there.

And if you call qmake directly in the console ?

Vel.

@SGaist

:) seems to output (shown below) the required :/ .... The installation seemed to have went correctly. I'm doing the 'make......xconfig' command (for a linux kernel modification) in a folder on my desktop. Simply going by this guide: http://arachnoid.com/android/Android-x86/
That's where I realized I need the Qt libraries so I installed them from the website. Is possible there is some conflict between some other systems?
I know I can use 'make ... menue config' instead since it doesn't use Qt libraries but it is case-sensitive which sucks on a mac since you need to do modifications there too (source: http://www.linuxchix.org/content/courses/kernel_hacking/lesson2 ) so I'd prefer 'make ... xconfig'

Pavels-MacBook-Pro:Qt Pavel$ qmake
Usage: qmake [mode] [options] [files]

QMake has two modes, one mode for generating project files based on
some heuristics, and the other for generating makefiles. Normally you
shouldn't need to specify a mode, as makefile generation is the default
mode for qmake, but you may use this to test qmake on an existing project

Mode:
-project Put qmake into project file generation mode
In this mode qmake interprets files as files to
be built,
defaults to *.c; *.ui; *.y; *.l; *.ts; *.xlf; *.qrc; *.h; *.hpp; *.hh; *.hxx; *.H; *.cpp; *.cc; *.cxx; *.C
Note: The created .pro file probably will
need to be edited. For example add the QT variable to
specify what modules are required.
-makefile Put qmake into makefile generation mode (default)
In this mode qmake interprets files as project files to
be processed, if skipped qmake will try to find a project
file in your current working directory

Warnings Options:
-Wnone Turn off all warnings; specific ones may be re-enabled by
later -W options
-Wall Turn on all warnings
-Wparser Turn on parser warnings
-Wlogic Turn on logic warnings (on by default)
-Wdeprecated Turn on deprecation warnings (on by default)

Options:

You can place any variable assignment in options and it will be *
processed as if it was in [files]. These assignments will be parsed *
before [files]. *
-o file Write output to file
-d Increase debug level
-t templ Overrides TEMPLATE as templ
-tp prefix Overrides TEMPLATE so that prefix is prefixed into the value
-help This help
-v Version information
-after All variable assignments after this will be
parsed after [files]
-norecursive Don't do a recursive search
-recursive Do a recursive search
-set <prop> <value> Set persistent property
-unset <prop> Unset persistent property
-query <prop> Query persistent property. Show all if <prop> is empty.
-cache file Use file as cache [makefile mode only]
-spec spec Use spec as QMAKESPEC [makefile mode only]
-nocache Don't use a cache file [makefile mode only]
-nodepend Don't generate dependencies [makefile mode only]
-nomoc Don't generate moc targets [makefile mode only]
-nopwd Don't look for files in pwd [project mode only]

Just thought of something: you are trying to cross-compile a linux kernel on OS X. You should rather create a virtual machine using e.g. VirtualBox and do everything directly form Linux. That will save you time.
