6.交叉编译libpng

在linux上交叉编译opencv之前需要交叉编译的依赖库 - 简书

１	pngstruct.h:30:10: fatal error: zlib.h: 没有那个文件或目录
	路径拼写错误
２	undefined reference to `png_init_filter_functions_neon'
	undefined reference to `png_init_filter_functions_neon'_singing1001的博客-CSDN博客

7.ffmpeg

1

./configure --prefix=/home/hisense/opencvDepend/3dmake --enable-shared --disable-static --enable-gpl --enable-cross-compile --arch=arm --disable-stripping --target-os=linux --enable-libx264 --enable-libxvid --cc=arm-linux-gnueabihf-gcc --enable-swscale --extra-ldflags=-L/home/hisense/opencvDepend/3dmake/lib --extra-cflags=-I/home/hisense/opencvDepend/3dmake/include --enable-avresample

8.Libffi

1	CC=arm-linux-gnueabihf-gcc ./configure --prefix=/home/hisense/opencvDepend/3dmake --host=arm-linux

9.glib

1

./configure --prefix=/home/hisense/opencvDepend/3dmake  CC=arm-linux-gnueabihf-gcc  LIBFFI_CFLAGS="/home/hisense/opencvDepend/3dmake/lib/libffi-3.2.1/include" \ LIBFFI_LIBS="-lffi-L/home/hisense/opencvDepend/3dmake/lib" ZLIB_CFLAGS="-I/home/hisense/opencvDepend/3dmake/include" \ ZLIB_LIBS="-lz -L/home/hisense/opencvDepend/3dmake/lib" --cache-file=glib.cache \  --disable-selinux  --disable-xattr --disable-libelf

Opencv编译问题列表

1	FFMPEG: NO
	cmake-gui通过Add Entry按钮添加 OPENCV_ENABLE_PKG_CONFIG，选bool类型，打勾。 RK1808交叉编译opencv with ffmpeg（解决FFMPEG始终为NO）_jbjhzstsl的博客-CSDN博客_undefined reference to `x264_8_nal_escape_neon
2	undefined reference to 'gzdopen'
3	fatal error: tiff.h: 没有那个文件或目录  #include "tiff.h
	关掉编译选项WITH_TIFF
	fatal error: dc1394/dc1394.h: 没有那个文件或目录  #include
4	在OpenCV的开放的源码里可以清楚的看到：OpenCV做了对1394接口的支持,至少是提供了接口，没有提供可供使用的驱动库； 关掉编译选项WITH_DC1394
5	error: size of array ‘_GStaticAssertCompileTimeAssertion_0’ is negative    G_STATIC_ASSERT(sizeof (unsigned long long) == sizeof (guint64));
	关掉编译选项 WITH_GStreamer
