hi,hippo Frambuffer build error!

Question

hi, hippo

When I build Micrwindows,failed.

/home/guor/nios2/dev/uClinux-dist-20070130/uClinux-dist/user/microwin/src/include/device.h:647:20: operator '==' has no left operand

It seems "MWPIXEL_FORMAT" is not defined.

in code I found this

/*

* MWPIXELVAL definition: changes based on target system

* Set using -DMWPIXEL_FORMAT=MWPF_XXX

*

* For the Nano-X server, it is important to use the correct MWPF_* value

* for the MWPIXEL_FORMAT macro in order to match the hardware,

* while the Nano-X clients that includes this file can get away with

* a default pixel format of 24-bit color as the client will either:

* 1) Use the MWPF_PIXELVAL native format when calling GrReadArea, in

* which case we have to have enough spare room to hold 32-bit

* pixlevalues (hence the default MWPF_TRUECOLOR0888 format), or

* 2) Will use some other PF_* format, in which case the application

* is well aware of which pixel-format it uses and can avoid the

* device specific RGB2PIXEL and use RGB2PIXEL565 etc. instead,

* and specifiy the pixel fomar as MWPF_TRUECOLOR565 etc. when

* calling the GrArea function(s).

*/

what should I do?where to define it?Must I edit the Makefile to fit it?

Did you use nios2 patches ver 2, and config microwin follow the wiki? http://nioswiki.jot.com/wikihome/operating...ems/framebuffer (http://nioswiki.jot.com/wikihome/operatingsystems/framebuffer)

I have not used microwin with NIOS, but on arm.

check the config file of microwindows if this is set correcty ...# #################################################################### # The pixeltype of the native hardware or underlying graphics library.# This definition defines the PIXELVAL to be 32, 16 or 8 bits wide.# If using Linux framebuffer, set to MWPF_TRUECOLOR0888, and use fbset.# It also enables GdArea/GrArea for this particular pixel packing format.# # define MWPF_PALETTE /* pixel is packed 8 bits 1, 4 or 8 pal index*/# define MWPF_TRUECOLOR8888 /* pixel is packed 32 bits 8/8/8/8 truecolor w/alpha*/# define MWPF_TRUECOLOR0888 /* pixel is packed 32 bits 8/8/8 truecolor*/# define MWPF_TRUECOLOR888 /* pixel is packed 24 bits 8/8/8 truecolor*/# define MWPF_TRUECOLOR565 /* pixel is packed 16 bits 5/6/5 truecolor*/# define MWPF_TRUECOLOR555 /* pixel is packed 16 bits 5/5/5 truecolor*/# define MWPF_TRUECOLOR332 /* pixel is packed 8 bits 3/3/2 truecolor*/# # ###################################################################

SCREEN_PIXTYPE = MWPF_TRUECOLOR888
