Cross compiling Qt 4.7.4 with directfb support for SH4 on 64 bit platform
-
Hello.
I am trying to cross compile Qt for sh4 on 64 bit platform. I created file mkspecs/qws/linux-sh4-g++/qmake.conf:
@include(../../common/g++.conf)
include(../../common/linux.conf)
include(../../common/qws.conf)modifications to g++.conf
QMAKE_CC = sh4-linux-gcc
QMAKE_CXX = sh4-linux-g++
QMAKE_LINK = sh4-linux-g++
QMAKE_LINK_SHLIB = sh4-linux-g++
QMAKE_CFLAGS_RELEASE = -Os
QMAKE_CXXFLAGS_RELEASE = $$QMAKE_CFLAGS_RELEASE
QMAKE_LIBDIR = /opt/STM/STLinux-2.3/devkit/sh4/target/usr/libmodifications to linux.conf
QMAKE_AR = sh4-linux-ar cqs
QMAKE_OBJCOPY = sh4-linux-objcopy
QMAKE_RANLIB = sh4-linux-ranlibQT_CFLAGS_DIRECTFB = -I/opt/STM/STLinux-2.3/devkit/sh4/target/usr/include/directfb -D_REENTRANT
QT_LIBS_DIRECTFB = -L/opt/STM/STLinux-2.3/devkit/sh4/target/usr/lib -ldirect -ldirectfb -lfusionQMAKE_STRIP = sh4-linux-strip
load(qt_config)@
and file mkspecs/qws/linux-sh4-g++/qplatformdefs.h:
@#include "../../linux-g++/qplatformdefs.h"@
After configuring with such string
@PKG_CONFIG=
which pkg-configPKG_CONFIG_PATH=/opt/STM/STLinux-2.3/devkit/sh4/target/usr/lib/pkgconfig ./configure --prefix=/opt/STM/STLinux-2.3/devkit/sh4/sh4-linux/usr/qt-4.7.4 -platform qws/linux-x86_64-g++ -embedded sh4 -little-endian -xplatform qws/linux-sh4-g++ -qt-gfx-directfb -opensource -confirm-license -no-qt3support -no-webkit -no-javascript-jit -no-script -no-scripttools -qt-zlib -qt-gif -no-libtiff -qt-libpng -no-libmng -qt-libjpeg -system-freetype -nomake examples -nomake demos -no-declarative -force-pkg-config@with "-platform" option or without it, I ran "make" and got error

@Why "-m64" option was added for sh4-linux-gcc? What's wrong? Can somebody help me?
