Compiling in release mode
Message 1 in thread
Hi everybody!
I'm having some problems compiling "Hello Qt" in release mode.
I type "qmake -project" and the file "hello.pro" is generated. Then I edit this file by adding the line "CONFIG = release". Then I enter "qmake hello.pro" and when I type "make", the following is displayed:
----------
g++ -c -D_HPUX_SOURCE -DGLU_VERSION_1_2 -O2 -I../qt/mkspecs/hpux-g++ -I. -I. -o hello.o hello.cpp
hello.cpp:1:26: qapplication.h: No such file or directory
hello.cpp:2:20: qlabel.h: No such file or directory
hello.cpp: In function `int main(int, char**)':
hello.cpp:6: error: `QApplication' undeclared (first use this function)
hello.cpp:6: error: (Each undeclared identifier is reported only once for each function it appears in.)
hello.cpp:6: error: expected `;' before "app"
hello.cpp:7: error: `QLabel' undeclared (first use this function)
hello.cpp:7: error: `label' undeclared (first use this function)
hello.cpp:7: error: `QLabel' has not been declared
hello.cpp:10: error: `app' undeclared (first use this function)
*** Error exit code 1
Stop.
----------
What's strange is that everything goes well if I don't perform that extra step of editing "hello.pro". Specifically the compilation command line is way more complete, with more include directories:
----------
g++ -c -D_HPUX_SOURCE -DGLU_VERSION_1_2 -g -Wall -W -D_POSIX_C_SOURCE=199506L -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I../qt/mkspecs/hpux-g++ -I. -I../qt/include/QtCore -I../qt/include/QtGui -I../qt/include -I. -I. -I. -o hello.o hello.cpp
g++ -Wl,+s -Wl,+b,/home/dcwt/xti-mp/qt/lib -o hello hello.o -L/home/dcwt/xti-mp/qt/lib -lQtGui_debug -L/home/dcwt/xti-mp/qt-x11-opensource-src-4.1.4/lib -L/usr/lib/X11R6 -lSM -lICE -lXi -lXext -lX11 -lQtCore_debug -lz -lm -ldld -lpthread
----------
Does anyone has na idea of what's going on?
BTW, I'm using:
* HP-UX B.11.11 U
* gcc 3.4.2
* Qt 4.1.4
Thanks in advance,
André

Yes, you didn't read the qmake manual close enough. You reset the CONFIG
variable to only include "release", which tells qmake to produe a
Makefile for a simple c++ program in release mode. What you also want is
to add the value "qt" to CONFIG. So CONFIG = qt release should get you
started, although you might also want to add warn_on and thread.
