首先，在執行./configure時，留意最後輸入結果保證正常執行完成，正常完成應該是沒有error字元的,例如:

...
configure: creating ./config.status
config.status: creating Makefile
 

config.status: creating zbar.pc
config.status: creating zbar-gtk.pc
config.status: creating zbar-qt.pc
config.status: creating doc/doxygen.conf
config.status: creating include/config.h
config.status: executing depfiles commands
config.status: executing libtool commands
config.status: executing doc/version.xml commands
config.status: executing doc
 
/reldate.xml commands

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=yes
Python            --with-python=no
GTK+              --with-gtk=yes
        => the PyGTK widget wrapper will *NOT* be built
Qt4               --with-qt=no
        => the Qt4 widget will *NOT* be built

如果報:Unable to find ImageMagick，安裝ImageMagick和libmagickwand-dev

apt-get install imagemagick libmagickwand-dev

如果報:error: no suitable Python interpreter found

說明沒有python環境或現有python和zbar需要的版本不一致，如果沒有涉及到python,新增引數--without-python

如果報:configure: error: test for video support failed!
rebuild your kernel to include video4linux support or
configure --disable-video to skip building video support.

新增--disable-video 引數

例如我的最後執行./configure引數:

./configure FLAGS="" --disable-video --without-python --without-qt
