1. Qt-2.3.10 Transplantation
The qt-2.3.10 has provided support for tslib, but the qws_mouse_proto it is not tslib, but tpanel, which is different from qte4.5

. The compilation process of tslib is no longer repeated. Check the article "QTE + tslib porting for ARM Linux platform". The difference is that qtopia Compilation

The tslib used for translation must be of the hardware FP type. Note that the tslib compilation process is shown below:

Bytes ----------------------------------------------------------------------------------------
Note:
(1)
If you use the maguscore compiler to generate tslib, the following error will be reported during the qtopia compilation process:
Libts. So use software FP, wherea libqpe. So use hardware FP.
Solution: Use the Aigo compiler to generate tslib and re-compile qtopia.

Export cc =/opt/Magus/ARM/3.4.6/bin/ARM-Linux-gcc

Aigo:
Export cc =/opt/mtwk/usr/local/gcc-3.4.3-glibc-2.3.4/ARM-Linux/bin/ARM-Linux-gcc

(2): Echo "ac_cv_func_malloc_0_nonnull = yes"> arm-linux.cache
If this sentence is not found, the error rpl_malloc cannot be found during make. Cause: # define malloc rpl_malloc is in configure.
In this case, you only need to write ac_cv_func_malloc_0_nonnull = yes to the. cache file, and allow configure to read this configuration from the file to bypass # define

Malloc rpl_malloc

Note:
When the input. So module is loaded, A segement fault error is thrown. This is because the _ ts_attach_raw () function in ts_attach.c in tslib

The NULL pointer is used.
It has been modified. For details, see ts_config.c.

Wait for a while, but you may choose to listen to a song !~

The above is just a rough description of the entire process, so we can't avoid errors. Let's take a look at it first and sort it out later ~!
