Problem cross-compiling with only framebuffer driver
by Ant Allen 11 Mar '04

11 Mar '04

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.

Errors when compiling grx for Linux Console - Please advise
by Ant Allen 11 Mar '04

11 Mar '04

Hi all, I'm trying to compile grx for linux on the framebuffer, _without_ svgalib. I made the following modifications to makedefs.grx: INCLUDE_PRINTING_CODE=n # Not sure what this is, so I don't want it, right? INCLUDE_BMP_CODE=n # Probably need this in future, but not yet INCLUDE_SHARED_SUPPORT=n INCLUDE_BGI_SUPPORT=n # What's bgi? USE_DIRECT_MOUSE_DRIVER=y USE_SVGALIB_DRIVER=n USE_FRAMEBUFFER_DRIVER=y SET_SUIDROOT=n # Not needed without svgalib, right? I then cd to the src directory and type: make -f makefile.lnx Part way through the compilation I get: gcc -c -O2 -Wall -DLFB_BY_NEAR_POINTER -pipe -DFRAMEBUFFER_DRIVER -I. -I./include -I../include fdrivers/svga24.c -o fdrivers/svga24.o fdrivers/svga24.c: In function `drawhline': fdrivers/svga24.c:256: error: can't find a register in class `AD_REGS' while reloading `asm' fdrivers/svga24.c:257: error: can't find a register in class `AD_REGS' while reloading `asm' fdrivers/svga24.c:258: error: can't find a register in class `AD_REGS' while reloading `asm' fdrivers/svga24.c:259: error: can't find a register in class `AD_REGS' while reloading `asm' make: *** [fdrivers/svga24.o] Error 1 Can anyone advise as to what the problem is, and how best to resolve it?

sdl driver release candicate 3
by Dimitar Zhekov 08 Mar '04

- reverted the driver name to const "sdl" - made sdl fullscreen a run-time option, ::fs or ::ww, default on for win~1 and off otherwise (i.e. x11) - implemented an ugly win~1 screen backup/restore; unfortunately, after Ctrl-Esc a fullscreen GRX app still has focus and writes to screen Direct[X]ly :-) -rc3 is to become official, except for the makefiles (see the -rc2 explanation). That's it IMHO. -- E-gards: Jimmy

xfdga avoid double detection
by Dimitar Zhekov 04 Mar '04

04 Mar '04

detect() didn't check if _XGrDisplay is already open. I'm not sure how relevant this is, my plans are to replace the partially working vd_xwin and it's problematic xfdga counterpart with vd_sdl, which will (as of -rc3) support fullscreen/windowed via GRX20DRV= ::fs and ::ww and have an ugly and incomplete Win~1 fullscreen backup/restore. -- E-gards: Jimmy
