[qmake] Generate Makefile with include $(ORACLE_HOME)/precomp/env_precomp.mk

[paulocarvalho_br_2009]

Greetings.

I want qmake to generate the Makefile with the following line preceding all other commands:

include $(ORACLE_HOME)/precomp/env_precomp.mk

include $(ORACLE_HOME)/precomp/env_precomp.mk

To copy to clipboard, switch view to plain text mode 

This is needed so the program can access Oracle databases. Every time I run qmake, I have to edit the generated Makefile to include that line.

Is there a way to atomatically include that line for every qmake run?

make changes to the qmake code to include your line at the end

What changes? By far I don't know any function or variable in the qmake documentation that seems to make a direct output to the generated Makefile. I want something that does the same thing as message() but instead of printing to console it prints to the Makefile.

talk2amulya said about changing qmake source code. you can add your own function, or modify message() to print to make file instead of console or something like this...

I don't know where exactly in your makefile your addidtional line should be but maybe modifying writeHeader() method in makefile.cpp in qmake sources (QTDIR/qmake/qmake.pro) can be enough.

P.S. or try Win32MakefileGenerator::writeStandardParts() or something like this :]

Oh yes, it's open source, I forgot... That's somewhat extreme, but if it solves the problem, that's good. I'll try it right now and share the results here...

1) Donwloaded source code = OK;
2) Renamed Makefile.unix -> Makefile = OK;
3) ran make. Got error: g++: cannot specify -o with -c or -S and multiple compilations.

How am I supposed to compile and build qmake?

[faldzip]

I guess you already have Qt with qmake, so just go to the qmake project dir (where qmake.pro is) and run qmake, then make :]

[paulocarvalho_br_2009]

Ok, I deleted the Makefile copied from Makefile.unix and some .o files generated, so I have an original source folder of qmake.

Changed current directory to ~/qt-x11-opensource-src-4.5.1/qmake/.

ran qmake on qmake.pro, got errors:

WARNING: Failure to find: qbitarray.cpp
WARNING: Failure to find: qbuffer.cpp
WARNING: Failure to find: qbytearray.cpp
...
+30 messages like that and aborts

The qmake used is installed somewhere else and belongs to Qt version 4.5.0.

The required files are under ~/qt-x11-opensource-src-4.5.1/src/corelib .

How can I make my installed qmake see those files?

[faldzip]

quite weird because I cded into qmake dir, typed qmake and it worked :]
Maybe there is something wrong with your QT_SOURCE_TREE variable, because as I see all the paths starts with this variable?

And I think that all you need is to modify qmake.pro where some paths to corelib directory are.

[paulocarvalho_br_2009]

By reading qmake.pro, one realizes that QT_SOURCE_TREE is supposed to be initialized somewhere else.

Of course when I try to qmake qmake.pro, QT_SOURCE_TREE is empty, thus qmake fails.

Questions:
1) Should I build the entire Qt and/or run the configure script?
2) Should I run some other script? I didn't find any shell scripts in qmake source directory.
3) Is it enough to export QT_SOURCE_TREE=<qt source parth>?

[paulocarvalho_br_2009]

Reading the INSTALL text file I realized I had to run the configure file in order to prepare the sources for building, even if I just want to build qmake. Please, forgive my "newbieness". qmake was succesfully built according to your instructions. Thanks. Now I will work on the source code and, if I get something useful, I'll share it with the community.
