kernel에서 qvfb설정하기

cd /usr/src/linux

# make mrproper

# make menuconfig  (아님 make xconfig)

1. Cide maturity level options 선택후 세부설정항복에서 Prompt for development and/or incomplete code/drivers 항복 선택

2. exit 선택후 초기메뉴에서 console drivers 선택후 세부항목 Frame-buffer support 선택

3. 다시 세부항목에서 Virtual Frame Buffer support 선택하고 Advance low level driver options에서 8bpp packed pixels support 와 16bpp packed pixels support 선택

4. Exit후 저장후 빠져나옴 (설정 완료)

# make dep

# make bzImage

# make modules

# make modules_install

# make install (새로운 커널이 grub 또는 lilo에 자동으로 등록됨.)

### 커널 컴파일 완료 ###

설치할 Qt와 tmake를 trolltech.com에서 다운로드

1] qt-x11-2.3.2.tar.gz

2] qt-embedded-2.3.2.tar.gz

3] tmake-1.13.tar.gz

압출풀고 구분을 위해 폴더명을 바꿈

tar xvfz qt-x11-2.3.2.tar.gz

mv qt-2.3.2 qtx-2.3.2

tar xvfz qt-embedded-2.3.2.tar.gz

mv qt-2.3.2 qte-2.3.2

Qt-X11 설치

cd qtx-2.3.2

export QTDIR=/usr/loca/program/qtx-2.3.2

export PAHT=$PATH:$QTDIR/bin

export LD_LIBRARY_PATH=$QTDIR/lib

./configure  (or ./configure -no-xft)      <-- xft 에러시 -no-xft 추가

make

QVFB 설치 후 Qt-embedded로 복사

cd tools/qvfb

make

./qvfg -width 640 -height 480 -depth 16     <-- 테스트로 한번 실행

cp qvfg /usr/loca/program/qte-2.3.2/bin/

Qt-embedded 설치

cd /usr/loca/program/qte-2.3.2

export QTDIR=/usr/loca/program/qte-2.3.2

export PAHT=$PATH:$QTDIR/bin

export LD_LIBRARY_PATH=$QTDIR/lib

./configure

make

Qt-embedded 테스트

./qvfb -width 640 -height 480 -depth 16 &

cd $QTDIR/examples/hello

./hello -qws

tmake 설치 (압출만 풀면 됨 : make 필요 없음)

cd /usr/loca/program/

tar xvfz tmake-1.13.tar.gz

export TMAKEPATH=/usr/loca/program/tmake-1.13/lib/qws/linux-x86-g++

export PATH=$PATH:/usr/loca/program/tmake-1.13/bin

arm용 컴파일러 설치(qt_libstdc++-3-libc6.1.2.2.10.0.so파일은 hybus 제공)

/usr/local/hyper-arm-linux-R1.1/ Toolchain설치된 상태에서

export PATH=$PATH:/usr/local/hyper-arm-linux-R1.1/bin

mv qt_libstdc++-3-libc6.1.2.2.10.0.so /usr/local/hybus-arm-linux-R1.1/lib/

ln –s qt_libstdc++-3-libc6.1.2.2.10.0.so /usr/local/hybus-arm-linux-R1.1/lib/libstdc++.so

Qt-embedded arm용 설치

cd /usr/loca/program/

mkdir /usr/loca/program/arm/

cp qt-embedded-2.3.2.tar.gz /usr/loca/program/arm/

tar xvfz qt-embedded-2.3.2.tar.gz

mv qt-2.3.2 qte-2.3.2

cd qte-2.3.2

./configure -xplatform linux-arm-g++

make

cd lib

file libqte.so.2.3.2               <-- ARM용으로 됐는지 확인

arm-linux-strip libqte.so.2.3.2   <-- strip 하기

ARM용 Tmake 설정

export TMAKEPATH=/usr/local/tmake-1.13/qws/linux-arm-g++

export PATH=$PATH:/usr/local/tmake-1.13/bin

Qt 설치 완료 및 ARM용 컴파일 준비완료

qt configure에선 항상...

1. 라이센스 동의 "yes"

2. everyting 5번

3. color depth에서 16bpp

4. Qt Virtual Framebuffer 지원 "yes"

1.PNG file 칼라수를 223으루  만든다.

2. libpng* 라이브러리들을 host /lib 에 복사

3. ./fblogo -4 test.png linux_logo.h 실행

4. linux_logo.h 을 사용하는 커널 include/linux/ 에 복사

5. 새로 컴파일해서 보드에 올리면 부팅때 프래임버퍼에서 뿌리는 그림이 달라진다.

gdb [실행파일명]

run -qws

그리고 실행 하시다 다운되면 “bt” 라고 입력하면 stack이 나옴.
