A migration steps:

1. Download tslib

Download point I entered or downloaded using the git command:
git address - https://github.com/kergoth/tslib.git

2. Go to the download directory or extract from the tslib

3. Do a few commands:

anzyelay@ubuntu:tslib$ ./autogen.sh  //得到configure
anzyelay@ubuntu:tslib$ ./configure  --host=arm-linux  --prefix=安装目录 CC=交叉编译器绝对路径
anzyelay@ubuntu:tslib$ make
anzyelay@ubuntu:tslib$ sudo make install

anzyelay@ubuntu:安装目录$ ls    //成功后在安装目录有如下文件
bin  etc  include  lib
  
  
  
  
   
   1
   
   2
   
   3
   
   4
   
   5
   
   6
   
   7

No absolute path will be out some problems, must be an absolute path.

4. The use to libraries and executable program into a corresponding root file system directory.

Two ways:

Here -> after the "/" refers to the root directory of the file system, not the root directory of your PC's, this tslib for stable post-transplant

All other files other than the removal pkgconfig directory tslib / lib / File -> / lib: Libraries
Program: Under tslib / bin files for all text -> / bin
Configuration: tslib / etc / ts.conf File -> /etc/ts.conf

You can also choose the entire directory into a directory in the root directory, but to do the corresponding change in the configuration environment variable, the error correction time for the beginning of transplantation,

5. Change the file system configuration files and adding environment variables

ts.conf: Depending on your touch-screen information on the development board canceled a comment, canceled here, a right to a trial following it.

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

In the / etc / profile add the following configuration according to their own file system:

export TSLIB_TSDEVICE = / dev / ts0 # selected here if the ts.conf event0 to be selected from the INPUT module_raw
Export TSLIB_CONFFILE = / etc / ts.conf
Export TSLIB_PLUGINDIR = / lib / TS
Export TSLIB_CALIBFILE = / TEMP / # Here is the calibrating pointercal files saved places, change the
Export TSLIB_CONSOLEDEVICE = none
Export TSLIB_FBDEVICE = / dev / fb0

If the method is the step 2, the configuration is as follows:

export TS_ROOT = / usr / local / tslib #tslib move to the file system directory
Export TSLIB_TSDEVICE = / dev / the 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 the PATH = $ TS_ROOT / bin: $ the PATH
Export the LD_LIBRARY_PATH = $ TS_ROOT / lib: $ the LD_LIBRARY_PATH

These configurations mean See tslib / README follows:

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. Do ts_calibrate correction

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

Second problem encountered Summary:

1. In implementing ./autogen.sh appear:

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

The reason is because there is no installation automake tools, install the following commands:
sudo apt-get install autoconf automake libtool

2. Do ./configure when there are mistakes:

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

Error handling, should make clean after each ./configure then execute 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

To specify the CC as follows, you must use an absolute address, or a third the following error:

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

  
  
  
  
   
   1
   
   2

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

The foregoing configuration, make all the way OK, but when an error make install as follows:

```
/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'

CC = absolute terms modify its address, as follows,
when an error

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

  
  
  
  
   
   1
   
   2

Correct

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

  
  
  
  
   
   1
   
   2

Although I have a good job compiler environment, can find arm-linux-gcc, but that is wrong, it is OK when using absolute addresses.

4. Perform the following error ts_calibrate

ERROR1:
/bin/ts_calibrate: line 1: syntax error: unexpected end of file
File under x86 actually found the file, not the arm.

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

   2

PATH variable later found the PC recovery, and should be turned back after sudo su is restored, view the / etc / profile is normal, the next re-run source / etc / profile, see PATH normal. And then recompile the normal installation:

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

  
  
  
  
   
   1
   
   2
   
   3

error2:

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

This is because the library does not result to see if the tslib / lib / libts-1.0.so.0 moved under / lib, if it is a method of shifting the entire directory tslib will have to specify the library search path as follows:
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

Because I selected the ts.conf module is "module_raw corgi", so the change in the configuration file TSLIB_TSDEVICE variables are as follows

export TSLIB_TSDEVICE=/dev/input/event0 
修改为
export TSLIB_TSDEVICE=/dev/input/ts0
  
  
  
  
   
   1
   
   2
   
   3

In-depth inquiry found the following correspondence relationship:
/ dev / the INPUT / event0 <-> module_raw the INPUT
/ dev / the INPUT / TS0 <-> module_raw Corgi
Both are possible, as long as the corresponding configuration profile ts.conf and write.
