根文件系统移植之tslib移植记录

一 移植步骤:

1. 下载tslib

点我进入下载地址或使用git命令下载：
git 地址– https://github.com/kergoth/tslib.git

2. 进入下载或解压出来的tslib目录

3. 执行下面几条命令：

anzyelay@ubuntu:tslib$ ./autogen.sh  //得到configureanzyelay@ubuntu:tslib$ ./configure  --host=arm-linux  --prefix=安装目录 CC=交叉编译器绝对路径anzyelay@ubuntu:tslib$ makeanzyelay@ubuntu:tslib$ sudo make installanzyelay@ubuntu:安装目录$ ls    //成功后在安装目录有如下文件bin  etc  include  lib

不用绝对路径会出些问题，一定要绝对路径。

4. 将要用到的库文件和可执行程序移入根文件系统中对应目录。

两种方法：

• 下面->后的”/”指的是根文件系统的目录，不是你PC机的根目录，这个适合tslib稳定后移植

  • 库：tslib/lib/文件下除去pkgconfig目录以外的其他所有文件 -> /lib
  • 程序：tslib/bin文件下所有文 -> /bin
  • 配置：tslib/etc/ts.conf文件 -> /etc/ts.conf

• 还可以选将整个目录放到根目录下的某个目录，但在配置环境变量时要做相应改变，这个适合开始移植时改错，

5. 更改文件系统的配置文件和添加环境变量

• ts.conf：依据你开发板的触摸屏资料取消一个注释,这里取消下面的，不对就一个一个的试吧。

  # Uncomment if you’re using a Sharp Zaurus SL-C700/C750/C760/C860
  module_raw corgi

• 在/etc/profile 中根据自己的文件系统加入以下配置：

  export TSLIB_TSDEVICE=/dev/ts0 #此处如果选event0则ts.conf中要选module_raw input
  export TSLIB_CONFFILE=/etc/ts.conf
  export TSLIB_PLUGINDIR=/lib/ts
  export TSLIB_CALIBFILE=/temp/pointercal #这里是配置校准文件保存地方的，可更改
  export TSLIB_CONSOLEDEVICE=none
  export TSLIB_FBDEVICE=/dev/fb0

  上一步如果是用的方法2，则配置如下：

  export TS_ROOT=/usr/local/tslib #tslib移动到文件系统里的目录
  export TSLIB_TSDEVICE=/dev/input/ts0
  export TSLIB_CONFFILE=$TS_ROOT/etc/ts.conf
  export TSLIB_PLUGINDIR=$TS_ROOT/lib/ts
  export TSLIB_CALIBFILE=/temp/pointercal
  export TSLIB_CONSOLEDEVICE=none
  export TSLIB_FBDEVICE=/dev/fb0
  export PATH=$TS_ROOT/bin:$PATH
  export LD_LIBRARY_PATH=$TS_ROOT/lib:$LD_LIBRARY_PATH

  这些配置意思查看tslib/README说明如下:

  42 43 TSLIB_TSDEVICE TS device file name. 44
  Default (non inputapi): /dev/touchscreen/ucb1x00 45
  Default (inputapi): /dev/input/event0 46 TSLIB_CALIBFILE
  Calibration file. 47 Default:
  ${sysconfdir}/pointercal 48 TSLIB_CONFFILE Config file. 49
  Default: ${sysconfdir}/ts.conf 50 TSLIB_PLUGINDIR Plugin
  directory. 51 Default: ${datadir}/plugins 52
  TSLIB_CONSOLEDEVICE Console device. 53 Default:
  /dev/tty 54 TSLIB_FBDEVICE Framebuffer device. 55
  Default: /dev/fb0

6. 执行ts_calibrate校正

[root@bst:/]# ts_calibrate
xres = 480, yres = 272
Took 26 samples…
Top left : X = 162 Y = 209

二 遇到的问题汇总：

1.在执行./autogen.sh 时出现：

./autogen.sh: 3: autoreconf: not found

产生的原因是因为没有安装 automake 工具，安装命令如下：
sudo apt-get install autoconf automake libtool

2.执行./configure时出现如下错误：

• erro1:

  libtool: install: error: cannot install `linear.la’ to a directory not ending in /usr/local/lib/ts
  make[2]: * [install-pluginexecLTLIBRARIES] Error 1
  make[2]: Leaving directory `/home/anzyelay/Desktop/arm/tslib/plugins’
  make[1]: * [install-am] Error 2
  make[1]: Leaving directory `/home/anzyelay/Desktop/arm/tslib/plugins’
  make: * [install-recursive] Error 1

  错误处理，在每次./configure后都要make clean再执行make.

• error2：

  libtool: install: (cd /home/anzyelay/Desktop/arm/tslib/plugins; /bin/bash /home/anzyelay/Desktop/arm/tslib/libtool –tag CC –mode=relink arm-linux-gcc -DTS_POINTERCAL=\”/home/anzyelay/Desktop/arm/tslib_install/etc/pointercal\” -DTSLIB_INTERNAL -fvisibility=hidden -DGCC_HASCLASSVISIBILITY -O2 -Wall -W -module -avoid-version -o linear.la -rpath /home/anzyelay/Desktop/arm/tslib_install/lib/ts linear.lo ../src/libts.la )

  libtool: install: error: relink `linear.la’ with the above command before installing it
  make[2]: * [install-pluginexecLTLIBRARIES] Error 1

  要指明CC如下，一定要用绝对地址，不然出下面第3个错误：

  anzyelay@ubuntu:~/Desktop/arm/tslib$ ./configure  --host=arm-linux --prefix=/home/anzyelay/Desktop/arm/myrootfs/usr/local/tslib CC=/usr/local/arm/4.4.3/bin/arm-linux-gcc

3. make install出libtool: install: error: relink `linear.la’ with the above command

前面配置，make都一路OK，但在make install时出错如下：

```/bin/bash ../libtool   --mode=install /usr/bin/install -c   linear.la dejitter.la variance.la pthres.la ucb1x00.la corgi.la collie.la h3600.la mk712.la arctic2.la tatung.la dmc.la linear_h2200.la input.la galax.la touchkit.la '/home/anzyelay/Desktop/arm/tslib/build/lib/ts'libtool: install: warning: relinking `linear.la'libtool: install: (cd /home/anzyelay/Desktop/arm/tslib/plugins; /bin/bash /home/anzyelay/Desktop/arm/tslib/libtool  --tag CC --mode=relink arm-linux-gnueabi-gcc -DTS_POINTERCAL=\"/home/anzyelay/Desktop/arm/tslib/build/etc/pointercal\" -DTSLIB_INTERNAL -fvisibility=hidden -DGCC_HASCLASSVISIBILITY -O2 -Wall -W -module -avoid-version -o linear.la -rpath /home/anzyelay/Desktop/arm/tslib/build/lib/ts linear.lo ../src/libts.la )libtool: relink: arm-linux-gnueabi-gcc -shared  -fPIC -DPIC  .libs/linear.o   -Wl,-rpath -Wl,/home/anzyelay/Desktop/arm/tslib/build/lib -L/home/anzyelay/Desktop/arm/tslib/build/lib -lts  -O2   -Wl,-soname -Wl,linear.so -o .libs/linear.so/home/anzyelay/Desktop/arm/tslib/libtool: line 8968: arm-linux-gnueabi-gcc: command not foundlibtool: install: error: relink `linear.la' with the above command before installing itmake[2]: *** [install-pluginexecLTLIBRARIES] Error 1make[2]: Leaving directory `/home/anzyelay/Desktop/arm/tslib/plugins'make[1]: *** [install-am] Error 2make[1]: Leaving directory `/home/anzyelay/Desktop/arm/tslib/plugins'make: *** [install-recursive] Error 1```

修改CC=项为其绝对地址，如下，
错误时

anzyelay@ubuntu:tslib$ ./configure --host=arm-linux --prefix=`pwd`/build CC=arm-linux-gcc

正确时

anzyelay@ubuntu:tslib$ ./configure --host=arm-linux --prefix=`pwd`/build CC=/usr/local/arm/4.9.4/bin/arm-linux-gcc

虽然我编译环境也设好了，可以找到arm-linux-gcc，但就是出错，使用绝对地址时就OK。

4.执行ts_calibrate出错如下

• error1:
  /bin/ts_calibrate: line 1: syntax error: unexpected end of file
  file了下发现居然是x86的文件，不是arm的。

  anzyelay@ubuntu:myrootfs$ file bin/ts_calibrate bin/ts_calibrate: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0xb79294591df01693dcc3ae349c4995c59a527f80, not stripped

  后来发现PC机的PATH变量复原了,应该是sudo su后转回来是复原的，查看/etc/profile是正常的，重新执行了下source /etc/profile，查看PATH正常了。再重新编译安装后正常：

  anzyelay@ubuntu:myrootfs$ file usr/local/tslib/bin/ts_calibrate usr/local/tslib/bin/ts_calibrate: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, not stripped

• error2:

  [root@bst:/]# ts_calibrate
  ts_calibrate: error while loading shared libraries: libts-1.0.so.0: wrong ELF class: ELFCLASS64

  这个是由于库文件不对造成的，看是否把tslib/lib/libts-1.0.so.0移到了/lib下，如果是用方法2整个tslib目录移的则要指定库文件的搜索路径如下：
  export TS_ROOT=/usr/local/tslib
export LD_LIBRARY_PATH=$TS_ROOT/lib:$LD_LIBRARY_PATH

• error3:

  [root@bst:/]# ts_calibrate
  xres = 480, yres = 272
  ts_read: Invalid argument

  因为我的ts.conf中选的模块是“module_raw corgi”，故更改配置文件中的TSLIB_TSDEVICE变量如下

  export TSLIB_TSDEVICE=/dev/input/event0 修改为export TSLIB_TSDEVICE=/dev/input/ts0

  深入探究发现有以下对应关系：
  /dev/input/event0 <—>module_raw input
  /dev/input/ts0 <—>module_raw corgi
  两者都是可以的，只要ts.conf和profile写上对应配置。

• error 4

  从Selected device is not a touchscreen这句看是TSLIB_TSDEVICE配置出错了，检查下：

  export TSLIB_TSDEVICE=/dev/input/event0

  查看下设备

  root@/etc# cat /proc/bus/input/devices I: Bus=0019 Vendor=0000 Product=0000 Version=0000N: Name="20cc000.snvs-pwrkey"P: Phys=snvs-pwrkey/input0S: Sysfs=/devices/soc0/soc.0/2000000.aips-bus/20cc000.snvs-pwrkey/input/input0U: Uniq=H: Handlers=kbd event0 evbug B: PROP=0B: EV=3B: KEY=100000 0 0 0I: Bus=0000 Vendor=0000 Product=0000 Version=0000N: Name="iMX6UL TouchScreen Controller"P: Phys=S: Sysfs=/devices/virtual/input/input1U: Uniq=H: Handlers=mouse0 event1 evbug B: PROP=0B: EV=bB: KEY=400 0 0 0 0 0 0 0 0 0 0B: ABS=3I: Bus=0003 Vendor=0c45 Product=6340 Version=0000N: Name="USB 2.0 Camera"P: Phys=usb-ci_hdrc.1-1.1/buttonS: Sysfs=/devices/soc0/soc.0/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-1/1-1.1/1-1.1:1.0/input/input3U: Uniq=H: Handlers=kbd event2 evbug B: PROP=0B: EV=3B: KEY=100000 0 0 0 0 0 0

  触摸屏是应该是event1,修改之重启，再次执行ts_calibrate
