Ubuntu系统下交叉编译libpng

一、参考资料

Ubuntu系统下交叉编译libpng-CSDN博客

二、交叉编译libpng

1. 下载源码

下载libpng：http://www.libpng.org/pub/png/libpng.html

下载并解压源码。

tar -xvzf libpng-1.6.45.tar.gz
cd libpng-1.6.45

2. 设置环境变量

设置交叉编译工具链的bin路径：

export PATH=/home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/bin:$PATH

3. 生成configure配置

# 创建安装路径
mkdir arm32_install

# 生成configure
./configure \
    --prefix=/home/yoyo/360Downloads/libpng-1.6.45/arm32_install \
    --host=arm-linux-gnueabihf \
    --with-sysroot=/home/yoyo/360Downloads/toolchains/arm-linux-gnueabihf/arm-linux-gnueabihf/libc \
    --enable-shared \
    --enable-static \
    CPPFLAGS="-I/home/yoyo/360Downloads/zlib-1.3.1/zlibbuild/include" \
    LDFLAGS="-L/home/yoyo/360Downloads/zlib-1.3.1/zlibbuild/lib" \
    LIBS="-lz"

输出示例：

yoyo@yoyo:~/360Downloads/libpng-1.6.45$ ./configure \
> --prefix=/home/yoyo/360Downloads/libpng-1.6.45/arm32_install \

----------------------------------------------------------------------
Libraries have been installed in:
   /home/yoyo/360Downloads/libpng-1.6.45/arm32_install/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
