linux zbar 编译报错解决记录/usr/include/x86_64-linux-gnu/bits/stdio2.h:143:1: error: expected identifie....

报错信息:

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

首先，在执行./configure时，留意最后输出结果保证正常执行完成，正常完成应该是没有error字符的,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

如果报:Unable to find ImageMagick，安装ImageMagick和libmagickwand-dev

apt-get install imagemagick libmagickwand-dev

如果报: error: no suitable Python interpreter found

说明没有python环境或现有python和zbar需要的版本不一致，如果没有涉及到python,添加参数--without-python

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

添加--disable-video 参数

例如我的最后执行./configure参数:

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