Zbar源码:
注意git上的源码无配置配置文件,
解压缩:
tar -jxvf zbar- 0.10.tar.bz2
2 配置文件
创建输出目录
cd zbar-0.10
mkdir output
配置编译ZBar库:
./configure --help
打印帮助信息,其中配置选项如下:
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--with-pic try to use only PIC/non-PIC objects [default=use
both]
--with-gnu-ld assume the C compiler uses GNU ld [default=no]
--with-gnu-ld assume the C compiler uses GNU ld default=no
--with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
--without-libiconv-prefix don't search for libiconv in includedir and libdir
--with-x use the X Window System
--without-xshm disable support for X shared memory extension
--without-xv disable support for XVideo extension
--without-jpeg disable support for JPEG image conversions
--without-imagemagick disable support for scanning images using
ImageMagick
--with-npapi enable support for Firefox/Mozilla/OpenOffice NPAPI
plugin
--without-gtk disable support for GTK+ widget
--without-python disable support for Python bindings
--without-qt disable support for Qt4 widget
配置文件:
./configure --prefix=$PWD/output/ --without-gtk --without-qt --without-imagemagick --without-python --disable-video
打印显示:
please verify that the detected configuration matches your expectations:
------------------------------------------------------------------------
X --with-x=yes
pthreads --enable-pthread=yes
v4l --enable-video=no
=> zbarcam video scanner will *NOT* be built
jpeg --with-jpeg=yes
Magick++ --with-imagemagick=no
=> the zbarimg file scanner will *NOT* be built
Python --with-python=no
GTK+ --with-gtk=no
=> the GTK+ widget will *NOT* be built
Qt4 --with-qt=no
=> the Qt4 widget will *NOT* be built
3 常见错误
我的错误1:
如果,这里是说你后面需要配置文件出错;请参考如下:
获取相关文件支持
1. $ sudo apt-get install libqt4-dev //qt相关
2. $ sudo apt-get install libv4l-dev
3. $ sudo ln -s /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h
4. $ sudo apt-get install python-gtk2-dev
5. $ sudo apt-get install imagemagick libmagickwand-dev/
例如
我想用jpeg,但是怎么配置都没有,这里就安装的包可以
sudo apt-get install imagemagick libmagickwand-dev 我的错误2:编译ZBar时,./configure之后make时提示如下错误。
usr/include/x86_64-linux-gnu/bits/stdio2.h:140:1: error: expected
identifier or ‘(’ before ‘{’ token In file included from
/usr/include/stdio.h:937:0, from zbar/debug.h:60, from
zbar/scanner.c:34: /usr/include/x86_64-linux-gnu/bits/stdio2.h:140:1:
error: expected identifier or ‘(’ before ‘{’ token
解决方法:
export CFLAGS="" //将CFLAGS环境变量置为空
然后重新 ./configure ***
此时再make,则会成功。
4. 结束
