안녕하세요.

Mango64(s3c6410)에 제작 Linux RootFileSystem에 qt lib를빌드하여 qt포팅중에 있습니다.

tslib까지 같이 빌드하였고, qt application실행, 동작에는 문제없이 잘 됩니다.

문제는 qt application 종료후

segmentation fault이나 Illegal instruction 오류가 발생합니다.

아무리 간단한 application을 실행하고 난뒤에도 오류가 발생합니다.

이유를 모르겠네요.

하루종일 삽질하다가 혼자의 힘으로는 안되나싶어 도움을 청해봅니다.

---------------------------------------------------------------------------------------------------------------------------------------------

1. tslib(최신버젼)

1) ./configure --host=arm-linux --prefix=/usr/local/tslib 이용하여 컴파일

2) # tslib
export TSDIR=/usr/local/tslib
export LD_LIBRARY_PATH=$TSDIR/lib:$LD_LIBRARY_PATH
export TSLIB_TSDEVICE=/dev/event1
export TSLIB_CONFFILE=$TSDIR/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_CONSOLEDEVICE=none
export QWS_MOUSE_PROTO=tslib:/dev/event1

2. Qt lib

1) ./configure --prefix=/usr/local/qt_arm -embedded arm -little-endian -opensource -qt-zlib -qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg -qt-freetype -qt-mouse-tslib

2) # QT
export QTDIR=/usr/local/qt_arm
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QTINC=$QTDIR/include
export QTLIB=$QTDIR/lib
export qt_prefix=$QTDIR
export QWS_DISPLAY="LinuxFb:/dev/fb0:mmWidth=160:mmHeight=160"

3) qmake.conf에 추가내용

QMAKE_INCDIR += /usr/local/tslib/include // tslib header, library 위치 설정
QMAKE_LIBDIR += /usr/local/tslib/lib
QMAKE_LFLAGS += -Wl,-rpath-link=/usr/local/tslib/lib

4) ts.conf 내용

# Uncomment if you wish to use the linux input layer event interface
module_raw input // 앞에 공백이 있으면 segmentation fault가 생긴다고 하던데 공백이 없는상태입니다.
