qmake to build both 32-bit and 64-bit

[lni]

I think I got it to work. You may need to treak for the QTDIR setting...

Fortran support also included. Comments are welcome!


For FORTRAN support (config.for)

CONFIG += f90

CONFIG(debug, debug|release) {
F90_CFLAGS = -g -O0
} else {
F90_CFLAGS = -O2
}

intel {
F90 = g77
}

isEmpty( F90 ) {
F90 = g77
}

ff90.input = F90_SOURCES
ff90.output = ${OBJECTS_DIR}${QMAKE_FILE_BASE}.o
ff90.commands = $$F90 -c $$F90_CFLAGS $$QMAKE_LFLAGS ${QMAKE_FILE_NAME} \
-o ${QMAKE_FILE_OUT} \
${INCPATH}
QMAKE_EXTRA_UNIX_COMPILERS += ff90

Support both 64-bit and 32-bit - config.h

# turn on the compiler warning
CONFIG += warn_on

#global definition
DEFINES = INT INTR3 QT3_SUPPORT

# global include file paths
MOC_DIR = .moc
UI_DIR = .ui
OBJECTS_DIR = .obj

# just a message
CONFIG(debug, debug|release) {
message(Building in debug mode.)
} else {
message(Building in release mode. Ignoring debug if it is available.)
}

contains( TARGET_BIT, m64 ) {
message(Building 64 bit )
QTDIR = /apps/qt64-422
BITS = 64
QMAKE_CFLAGS = -m64
QMAKE_CXXFLAGS = -m64
QMAKE_LFLAGS = -m64
}

contains( TARGET_BIT, m32 ) {
message(Building 32 bit )
QTDIR = /apps/qt32-422
BITS =
QMAKE_CFLAGS = -m32
QMAKE_CXXFLAGS = -m32
QMAKE_LFLAGS = -m32
}

!isEmpty( TARGET_BIT ) {

} else {

INCLUDEPATH += ${QTDIR}/include/Qt3Support
}

Fortran example - fortran.f

C example - cfile.c

C++ example - c++file.cpp

build64/build64.pro

TARGET_BIT = m64
include ( ../common.pri )

common.pri - path needs to be reset to fit your system
