CUPS移植记录

CUPS，即Common Unix Printing System 是一个UNIX系统下的打印管理程序。
移植编译过程：

#!/bin/sh  # 1.下载源码  wget http://www.cups.org/software/1.3.9/cups-1.3.9-source.tar.gz &&  # 2.解压并打开  tar xvzf cups-1.3.9-source.tar.gz && cd cups-1.3.9 &&  # 3.配置  ./configure --host=arm-linux --target=arm-linux --build=i686-linux CC=arm-linux-gcc CXX=arm-linux-g++ LD=arm-linux-ld RANLIB=arm-linux-ranlib AR=arm-linux-ar  --disable-gnutls --disable-gssapi --disable-dbus --prefix=/ &&  # 4.修改Makefile使其不编译man  sed -i '22s/locale man monitor/locale monitor/' ./Makefile  &&  # 5.编译并安装  make && make install DSTROOT=${PWD}/_install &&  echo "cups build install ok!"

部署到目标板子上后，正常情况下启动CUPS：

# /etc/init.d/cups startcups: started scheduler.# # lpinfo -vnetwork socketnetwork httpnetwork ippnetwork lpddirect scsi## lpadmin Usage:    lpadmin [-h server] -d destination    lpadmin [-h server] -x destination    lpadmin [-h server] -p printer [-c add-class] [-i interface] [-m model]                       [-r remove-class] [-v device] [-D description]                       [-P ppd-file] [-o name=value]                       [-u allow:user,user] [-u deny:user,user]

以下是会遇到问题：

1. busybox的PS命令和PC端不一致

# /etc/init.d/cups startps: invalid option -- 'a'BusyBox v1.17.2 (2010-12-30 11:13:11 HKT) multi-call binary.Usage: ps Show list of processesOptions:        w       Wide output

解决方法：
将/etc/init.d/cups的162行ps ax改为ps w改后如下：

pid=`ps w | awk '{if (match($5, ".*/cupsd$") || $5 == "cupsd") print $1}'`

2. 库文件路径不正确

# lpstatlpstat: error while loading shared libraries: libcups.so.2: cannot open shared object file: No such file or directory

解决方法：
这些库文件存在于/usr/lib64目录下，一种方法是将/usr/lib64也作为运行库目录；另一种方法是将/usr/lib64目录下的内容拷贝到/usr/lib目录下解决问题。cp usr/lib64/* /usr/lib/

3. error while loading shared libraries: libssl.so libcrypto.so.1.0.0

# /etc/init.d/cups start/usr/sbin/cupsd: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory/usr/sbin/cupsd: error while loading shared libraries: libcrypto.so.1.0.0: cannot open shared object file: No such file or directorycups: unable to start scheduler.

解决方法：将交叉工具链中的库拷贝进来。
