Re: Getting qtquran to compile in Kdevelop (version 0.4 - from sourceforge)

[Kumade Khawi <al_khawi at yahoo dot com>]

Salaam all, my first mailing here :-)

I have download the "quran" package several times and
it gives me EOF errors. Tarball corrupted methinks.

For the following comments, I am cross-referencing the
CVS sources from the *web* interface, Revision 1.6.

line 44: quran_audio * qa;

GCC doesn't see the defenition for the type
"quran_audio". You will either need to run ctags/etags
on your project to get the cross-referencing info
(highly recommended.) or you will need to grep for it.
Grep will return ALL the occurences of "quran_audio"
and no just the defenition.

I will save you the chase however and tell you what my
gut feeling is about this type. If you look at
quran/libquran, you will see the files quranaudio.h
and  .c. If anything, quran_audio should have been
defined there (as logic dictates.) but I guess what we
are looking at is just the framework and the
maintainer hasn't gotten around to implementing
"quran_audio" just yet. So, what you're looking at
might not be ready yet :-(

If the defenition of "mainWindow" follows the rest of
the clean design of the project, then the class
mainWindow should be defined in the header
"mainwindow.h", which also I THINK is going to be
generated from mainwindow.ui by some preprocessor. I
am not a Qt guy .. yet.

[snip errors from line 71 to 139]
these are nothing but cascading errors. Once
mainWindow's header is properly included, half of
these  errors will disappear.

For main.cpp, I am looking at Revision 1.5 in the CVS.

Just to show you how clean and idiomatic the code is,
I immediately guessed the location where the function
quran_init() is defined: quran/libquran/quran.h,
altough it could have also been in
quran/libquran/init.h.

To fix this, you will have to add this to the top of
main.cpp:
#include "quran.h", right after the inclusion of
qtranslator.h (i.e. after the Qt headers.)

If you look closely, is is calling
QTranslator::load().
Look at the Qt API (google) and you will see that the
second argument is supposed to be a constant qt
string,
but the code is calling it as

QTranslator::load( ..., QTQURAN_SHARE_DIR "/lng");

it is trying to concatenate QTQURAN_SHARE_DIR and
"/lang", so I am guessing that QTQURAN_SHARE_DIR is
actually an string /somewhere/ and the author gave it
this convenience macro defenition.

OTOH, it might as well be a type, he might have meant
QTQURAN_SHARED with a D. Or it might even be a
legitimate piece of code accepted by the Qt or C
preprocessors. We can't say much with cross-referncing
tools.

[snip the rest of the code]

These "declared but never defined" errors are nothing
but "You have created the header file, now implement
the source." I think you are looking at incomplete
code .

Shoot me a non-corrupted tarball at kkhawi at pobox dot com
and I will look at it over the weekend.
