What can I do to fix this?

Interesting problem; just downloaded and installed on home
windows 7 machine and did the same steps and it worked
(no surprise as our automated tests pass this)

So there must be something different in your environment..

Let's see... please try the following commands on madde terminal:

Code:

$ cd
$ pwd -W
$ cd /
$ pwd -W

and report output

I created basically identical paths myself and it still works (which is good
as the bug would have been severe...)

now cd back to 'qthello' -directory. then try the following commands:

Code:

ls ..
ls ../..
ls ../../..
ls ../../../0.6.72/
ls ../../../0.6.72/sysroots/
...
ls ../../../0.6.72/sysroots/fremantle-arm-sysroot-10.2010.19-1-slim/usr/share/qt4/mkspecs/default/qmake.conf'

and show the output of last successful command.

ls: ../../../0.6.72/: No such file or directory

MADDE-0.6.72 ~/qthello

Looks like ../../.. maps to ../../../0.6.72/

After more investigations:

When I replace '../../../0.6.72/sysroots' by '/sysroots' in the makefile generated by qmake the project builds!

Any idea where the ../../../0.6.72 used by 'mad qmake' is coming from?

I just realized something... nasty one...

I'm not close to any windows machine now so I cannot test.

To get something done, in MADDE terminal, do first:

cd /d/temp

(and create stuff there)... any other directory works also, provided
there is no whitespaces in it's path.

EDIT: yes, I have idea. there is /home remapping in /etc/fstab
(in MSYS context) which breaks things. And we did not realise
the problem this particular case brings up.

JapieB (and anyone else having the same problem)

open MADDE terminal and enter:

Code:

echo > /etc/fstab

This removes the /home -mapping and makes things work.

Notice that /home moves one deeper in directory hierarchy,

from <MADDE>/home to <MADDE>/0.6.72/home

where <MADDE>/0.6.72 equals '/' in MSYS context.

new home directory is created when new MADDE terminal
is opened

Fixed! the example can be executed fully now!

Thanx,

I just upgraded MADDE to the latest version, and the MADDE terminal now opens to my Windows user directory: C:\Users\talvala, instead of under MADDE:

Code:

MADDE-0.6.72 ~
talvala $ cd

MADDE-0.6.72 ~
talvala $ pwd
/c/Users/talvala

And trying to build the qthello example results in the same problem as people have been seeing, even after the 'echo > /etc/fstab' fix:

Code:

MADDE-0.6.72 ~/Repositories/tmp/qthello
talvala $ mad qmake

MADDE-0.6.72 ~/Repositories/tmp/qthello
talvala $ mad make
make: *** No rule to make target `../../../Users/talvala/Repositories/tmp/qthello/qtprog.pro', needed by `../../../Users/talvala/Repositories/tmp/qthello/Makefile'.  Stop.

Any idea what broke in the installation? I've tried uninstalling MADDE completely and reinstalling, with no change in the result. This is Windows 7 x64.

If you read what make tells you, No rule to make target, this means that there is a dependency that can not be satisfied with either rules in the makefile or the built in rules.

Find the qtprog.pro file and place it in the build tree at a location where it matches the rule in the makefile.

Find the qtprog.pro file and place it in the build tree at a location where it matches the rule in the makefile.

The .pro file is in the same directory as the Makefile, and since qmake generated the Makefile from the .pro file, it should get the path right on its own.

Essentially, it's prepending a huge roundabout directory path in front of files inside the project, completely unneccessarily. If I manually remove the lengthy ../../../Users/talvala/Repositories/tmp/qthello/ section from all paths in the Makefile, it works fine. But that gets tedious very quickly, and qmake shouldn't be doing such a thing in any case - why doesn't it just encode the local relative paths, instead of what looks like an attempt to round-trip through 5 layers of directories?
