Hello,
I found that tqt.h is modified only at install stage. If I define USE_QT3
before compilation, the compilation stop with this error:
tqinputcontext.h:32:27: error: qinputcontext.h: No such file or directory
This is intended behaviour? If yes, for what purpose is designed in this way?

Hello,
I found that tqt.h is modified only at install stage.
That is correct, however the automake/autoconf system defines USE_QT3 or
USE_QT4 based on the Qt version specified in admin/acinclude.m4.in.
The new CMake-based build system will also need to define USE_QT3 or
USE_QT4 when it builds any of the Trinity modules. This is to allow
conditional code within Trinity so as to maintain build compatibility with
both versions of Qt.
If I define USE_QT3
before compilation, the compilation stop with this error:
tqinputcontext.h:32:27: error: qinputcontext.h: No such file or directory
This is intended behaviour? If yes, for what purpose is designed in this
way?
No, that is not the intended behaviour. Do you have the qinputcontext.h
header file present on your system? The old autoconf/automake system
actively searched for the Qt headers and added the that directory to the
include search path in the gcc flags.
Also please be aware that for all modules that rely on TQt, you will need
to detect the presence of the TQt headers, and pass the "-include tqt.h"
flag to gcc. You should also add the TQt header directory to gcc's
include search path.
Hope this helps some!

I created a file named TQt.pc, for detecting is via pkg-config
flag to gcc. You should also add the TQt header
directory to gcc's
include search path.
Good to know.

You right, this file is present in official Qt3 package. I guess that is
missing on mine system because gentoo permit few flags which can omit some Qt
modules. I will make checks, as you suggest.

It is present in my version of Qt3; see this page:
http://packages.ubuntu.com/lucid/i386/libqt3-headers/filelist
I am not sure why it does not exist on your system. If it is not a
generic file present on all Qt installations then you may have to let
CMake search for it and conditionally remove the reference to it based on
the CMake search results.

What you suggest to do in this case?

I will put a conditional around the include statement in tqinputcontext.h
like this
#ifndef QT_NO_XIM
#include <qinputcontext.h>
#endif
If you want you can try this out for me before I commit it to SVN...just
modify the tqinputcontext.h file as shown and try a rebuild.

Not yet, i think that the real problem is not XIM support, but the existence
of immqt patch. First I will try to detect the presence of these files.

I compiled Qt3 with immqt support and now I have qinputcontext.h and
qinputcontextfactory.h. However, I will check for presence of these files and
I will exclude tqinputcontext.{h,cpp} and tqinputcontextfactory.{h,cpp} from
compiling/installing, if necessary.
Maybe (sometime) we will insert something like this in these files:
#ifndef HAVE_QINPUTCONTEXT_H
#error Your TQt have no qinputcontext support!
#endif
