Taglib编译

交叉编译的脚本：

# this is required

SET(CMAKE_SYSTEM_NAME Linux)

# specify the cross compiler

SET(CMAKE_C_COMPILER   /home/hs/mentor/bin/arm-none-linux-gnueabi-gcc)

SET(CMAKE_CXX_COMPILER /home/hs/mentor/bin/arm-none-linux-gnueabi-g++)

# set build flag

SET(GNU_FLAGS "-march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon -mtune=cortex-a9 -fPIC -Wall")

SET(CMAKE_CXX_FLAGS "${GNU_FLAGS}")

SET(CMAKE_C_FLAGS "${GNU_FLAGS}")

# 

IF( NOT CMAKE_BUILD_TYPE )

   SET( CMAKE_BUILD_TYPE Release ... FORCE )

ENDIF()

#SET(CMAKE_INSTALL_PREFIX /home/test/testTaglib/taglib-1.10/cross_build)

# where is the target environment 

SET(CMAKE_FIND_ROOT_PATH  /home/hs/mentor)

# search for programs in the build host directories (not necessary)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

# for libraries and headers in the target directories

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)

SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

# configure Boost and Qt

#SET(QT_QMAKE_EXECUTABLE /opt/qt-embedded/qmake)

#SET(BOOST_ROOT /opt/boost_arm)

-----------------------------------
编译步骤：
mkdir cross_build
cmake -DCMAKE_INSTALL_PREFIX=/home/hs/taglib/cross_build -DCMAKE_BUILD_TYPE=Release  -DCMAKE_TOOLCHAIN_FILE=./toolChain.cmake
make
make install

---------------------------------------
解决运行时链接不到so文件的问题：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/app/xx/lib:
