Re: SVGA Source Code
Hello Wooley,
Thanks for your reply.
Sorry for such a mail.
What I want to say is, I am Cross Compiling SVGALIB for
ARM. For that I am using openembedded toolchain. I have really tried
hard to compile svgalib package against ARM toolchain. For that I have
disabled VESA support in Makefile.cfg. Also disabled svga utils. But Now
the problem is I am facing while linking my application to vgalib. I am
getting "undefined reference to outsb".
But When I tried to cross compile svgalib package with VESA support, I
am getting following error:
"vga.c:34: /sys/vm86.h : No such file or directory"
I think if I am right, that file belongs to x86 architecture.
I have got some link of svgalib debian package for ARM. So I have
contacted you, how svgalib package is cross compiled. What things I need
to consider while cross compiling. I am attaching you my Makefile.cfg.
Regards,
Sanket Patange

Hello,
I'm having trouble understanding your question. Please clarify a
a little.
I am compiling SVGA Source code for ARM against my
toolchain.
What 'SVGA Source code' exactly? Is it your own? Or something from
Debian?
What toolchain and what device are you compiling for?
Actually debian packages are not working on my filesystem.
What sort of 'not working' - what is the error/problem? What
filesystems are you using - one supplied with a dev board? Which
Debian packages (arm, armel, armhf)?
I am always getting " undefined reference to outsb".
When you iunstall a Debian pakcage or when you try to compile your
'SVGA Source'? I assume the latter.
insb and outsb are single instructions on x86 - they have to be
replaced by code on other platforms, to iterate over outb.
You may be trying to build x86 assembler on ARM which won't be
recognised, or you may just have failed to include the relevant
headers to provide these IO macros.
Please guide me regarding how to cross compile svga source code for
ARM.
We need more details of your problem to provide useful guidance.
Also provide me the SVGA Source Code.
If you are building it you must have it already - I don't understand
what you mean here.
