qtopia-2.2.0的交叉编译以及移植Ⅰ

jpeg:

cd /root/2410s/jpeg-6b

export PATH=/usr/local/arm/2.95.3/bin:$PATH

export CC= /usr/local/arm/2.95.3/bin/arm-linux-gcc

     ./configure –enable-shared

     vi Makefile

     修改生成的Makefile文件

     prefix= /root/2410s/qt-2.3.10-arm

     CC= /usr/local/arm/2.95.3/bin/arm-linux-gcc

     AR= /usr/local/arm/2.95.3/bin/arm-linux-ar rc

     AR2= /usr/local/arm/2.95.3/bin/arm-linux-ranlib

     cp jconfig.doc jconfig.h

     mkdir -p /root/2410s/qt-2.3.10-arm/man/man1

     make

     make install -lib

    *******

    报错,但是在/root/2410s/qt-2.3.10-arm/lib目录下生成了文件夹fonts和libjpeg.so*

    ********

cp jpeglib.h /root/2410s/arminclude

cp lib/libjpeg.so* /root/2410s/armlib

就可以给qt-embedded添加好for arm的libjpeg库.

放到交叉编译的Lib一份

cp lib/libuuid.so* /usr/local/arm/2.95.3/arm-linux/lib

zlib:

     cd /root/2410s/zlib-1.2.3

     export PATH=/usr/local/arm/2.95.3/bin:$PATH

     export LD_LIBRARY_PATH=/usr/local/arm/2.95.3/arm-linux/lib:$LD_LIBRARY_PATH

     export CC= /usr/local/arm/2.95.3/bin/arm-linux-gcc

      ./configure –shared

     vi Makefile

     修改:

     [begin]

     ...

     CC=/usr/local/arm/2.95.3/bin/arm-linux-gcc

     ...

     LDSHARED=/usr/local/arm/2.95.3/bin/arm-linux-gcc -shared

-Wl,-soname,libz.so.1

     CPP=/usr/local/arm/2.95.3/bin/arm-linux-gcc -E

     ...

     AR=/usr/local/arm/2.95.3/bin/arm-linux-ar rc

     RANLIB=/usr/local/arm/2.95.3/bin/arm-linux-ranlib

     ...

     prefix =/usr/local/arm/2.95.3/arm-linux

     ...

     [end]

     make

     cp libz.so* /root/2410s/armlib

     cp *.h /root/2410s/arminclude (我只拷贝了zlib.h)

 把生成的库文件libjpeg.so*向下面的目录中也拷贝一份:

/usr/local/arm/2.95.3/arm-linux/lib

     ****************

     切记设置

export  LD_LIBRARY_PATH=/usr/local/arm/2.95.3/arm-linux/lib:$LD_LIBRARY_PATH

     否则会出现错误,库会调用libc.so.6不是arm 而是x86的

     chmod: error while loading shared libraries: libc.so.6: ELF file OS ABI invalid
