Problem creating Library Debian Package

**MariusLinux** · December 22nd, 2014

Hi,
I'm currently trying to create a Debian package of my library 'QTurtle' (written in C++, using Qt, providing 'turtle graphics for Qt's QGraphicsScene, made for a little project), including a -dev package. I've got a directory 'libqturtle-1.0', containing the source code (qturtle.cpp, qturtle.h, qturtle.pro, qturtle_global.h), nothing else. Here is the .pro file:

Code:

QT       += widgets

TARGET = qturtle
TEMPLATE = lib

DEFINES += QTURTLE_LIBRARY

SOURCES += qturtle.cpp

HEADERS += qturtle.h\
        qturtle_global.h

unix {
    headersf.files = $$HEADERS
    headersf.path = /usr/include
    target.path = /usr/lib
    INSTALLS += target
    INSTALLS += headersf
}

In this directory, I run:

Code:

dh_make --createorig

It produced the following output:

Code:

Currently there is no top level Makefile. This may require additional tuning.
Done. Please edit the files in the debian/ subdirectory now. You should also
check that the libqturtle Makefiles install into $DESTDIR and not in / .
Make sure you change the package name from libqturtleBROKEN to something
else, such as libqturtle1 in the debian/control file.

It created everything like it should. In the current's dir 'debian' subdir, I've removed all the unnecessary files, leaving only this:

Code:

libqturtle (1.0-1) utopic; urgency=low

The 'debian/source' subdir contains format, containing:

Code:

3.0 (quilt)

copyright and docs remained unchanged, as I am just trying to build this package, only if this succeeds, I am going to think about this files

Next, ran:

Code:

dpkg-buildpackage -S -us -uc

Output:

(if you need English output, just tell me, I will switch my system's language from German to English

)

Code:

debuild -us -uc

The error seems to be:

I don't have any clue why this happens, and I haven't found a solution yet, if anybody of you could help me, that would be really great

THX in advance,
Marius

Any *.install, *.dirs, *.docs and so on under debian/ with executable bit set is considered a script and debhelper will try to execute them. With executable bit unset they are considered just file/directory lists. So try

Code:

chmod -x debian/libqturtle-dev.dirs

Thank you very much

This finally solved my problem, but for somebody maybe having the same problem: '/media/Daten' is a NTFS partition on my harddisk :-/
So that's the reason why the executable bit wasn't set. Really stupid mistake. Don't try packaging on NTFS.

Greetings,
Marius
