Patch version 0.8 of SDL(Simple DirectMedia Layer) for Nano-X API
|
|
=================================================================
|
|
|
|
Author: Hsieh-Fu Tsai, clare@setabox.com
|
|
|
|
There are two patch files in this package.
|
|
|
|
1. The first patch file, nanox.patch, is to fix a bug in Nano-X.
|
|
This patch is proposed by Gary James (gjames@twcny.rr.com).
|
|
|
|
It fixes the client side GrClose(). In the original version,
|
|
GrOpen() can only be called once. When the GrOpen() is called at
|
|
the second time, the program will terminate. In order to prevent
|
|
this situation, we need to insert "nxSocket = -1" after
|
|
"close(nxSocket)" in GrClose(). If you do not have this problem,
|
|
you may skip this step.
|

=============
|
|
Quick Install
|
|
=============
|
|
|
|
1. ./configure --disable-video-x11 --disable-video-fbcon \
|
|
--enable-video-nanox \
|
|
--with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal]
|
|
2. make clean
|
|
3. make
|
|
4. make install (as root)
|
|
|
|
============
|
|
Nitty-gritty
|
|
============
|
|
|
|
--with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal]
|
|
|
|
If the wrong pixel type is used, the program will crash when the
|
|
sub-routine updates the screen. This option depends on SCREEN_PIXTYPE
|
|
which is defined in Microwin0.89pre7/src/config. SCREEN_PIXTYPE
|
|
is used to define the pixel type in Microwindows/Nano-X.
|
|
I only test the program when the pixel type is in "rgb"
|
|
(Microwin under X11) or "888" (framebuffer in 24-bit).
|
|
|
|
--enable-nanox-debug Show debug messages
|
|
--enable-nanox-share-memory Use shared-memory to speed up
|
|
