Hi, I cross-compile grx for an embedded system, too. I think that there is a mistake in the config files, and it always assumes that there is a svga hardware present. You can simply edit fdrivers\ftable.c and comment out the drivers you don't use, although it is more elegant if you: - make your own makefile (grx\src\makefile.custom) that is a copy of makefile.lnx. I don't like to modify the standard one - in this makefile add CCOPT += -DONLY_FRAMEBUFFER - in the file src\fdrivers\ftable.c replace the line #if !defined(__XWIN__) && !defined(__WIN32__) with #if !defined(__XWIN__) && !defined(__WIN32__) && !defined(ONLY_FRAMEBUFFER) I hope this helps. If it doesn't or you have more questions, don't hesitate to contact me privately. Josu Onandia

Hi,

I'm now trying to cross-compile grx for use on an embedded xscale platform. I'm using arm-linux-gcc 2.95.3.

I've disabled svgalib and am compiling for the linux framebuffer with makefile.lnx.

The first problem I hit was libgrx.h referencing /sys/byteorder.h. This seemed to be asm related so I simply commented out that line in the source.

Next problem is src/makefile.lnx lists various graphics drivers such as ega.c egavga.c etc etc. As I'm compiling for the framebuffer only I commented these out in the makefile.

Everything now seems to compile, but I get a problem when linking - see below.

Can anyone suggest a solution?

Ideally I'd like to test out the cross-compilation with some either the grx demo or with the examples from the documentation. How far from this am I?

All help greatly appreciated. Ant
