I can't get a working cross compiler

konsole — Wed, 08 Nov 2006 05:53:43 -0000

I have gentoo linux with gcc-4.1.1. I just can't seem to get anything to work. I don't want to have to use cygwin to get it to work! First I tried to use the gentoo method(crossdev) to install the gcc-4 cross compiler, only to find that the target is no longer supported and is now something like h8300-elf. Then I followed the cygwin instructions to compile gcc-2.95 and binutils. binutils installed fine but the gcc build failed. Next I got the latest gcc and binutils ard tried to build for --target=h8300-elf but the gcc build failed there too. I am thinking about trying to install those debian binary packages even though I don't have debian.

I really don't know what I am doing. I don't have any idea if it needs exactly h8300-hitachi-hms, or exactly that version of gcc, or if the newer gcc's need those patches that the cygwin script uses. Does everyone that uses brickOS use cygwin or debian? I couldn't find any directions for installing for a normal *nix system.

I would really like to use brickOS without having to use windows. Could someone help me set up a cross compiler that will work with brickOS?

Thanks

runninng into some issues after a ?successful? firmdl3

brickOS.srec (0.9.0) request

efronberg — Thu, 22 Sep 2005 19:43:06 -0000

I'm working on getting brickos to compile and run under MacOSX.
Currently I believe I'm compileing ok and have gotten firmdl3
to download *my* version of brickos.srec to the brick.

I'm debugging problems now with dll.

I'm not sure if problems are from brickos.srec/ My drivers
for the tower or something else.

To this end, I'd like to have someone send me a working copy
of brickos.srec (0.9.0) so that I can download and see
how it runs compared to the version that I have.

thanks!

Where is the math library?

DrRex — Sun, 20 Mar 2005 12:03:01 -0000

Hello!

I have installed my tools after this tutorial, and haven't
changed any critital stuff.
http://brickos.sourceforge.net/docs/INSTALL-cygwin.html

I have searched both gcc / brickos and google, but
without luck.

I have searched without luck on google for comments on
this subject.

Where do I find a math library for RCX ? (integer and/or
float)
Are there both fast and slow precise editions?
With all due respect. Is it just me, or should a math
library be a part of BrickOS ?

I have made all the calculations and formulas. Now I just
need to implement them in C++ (Maby C) and therefore
need the math part. This problem occured earlyer to me,
but I was busy and had to abandon the project.

Syntax errors in files?

Anonymous — Thu, 03 Mar 2005 21:13:08 -0000

When installing brickOS under WinXP and Cygwin, I get
several errors. After having typed the command
[code]./configure; make[/code] I get the following error:
....
/brickOS/kernel/lnp.c:152:9: missing terminating
character "
/brickOS/kernel/lnp.c:171:3: missing terminating
character "
....
So when I go to this file lnp.c and I remove the
quotes, the error disappears, but then other syntax
errors are shown.
Is there an explanation for it?
Thx

GUI communication with BrickOS

Anonymous — Sun, 23 Jan 2005 06:33:03 -0000

Hello,
I am new to Mindstorms and an trying to create an
autonomous robot using the RCX. I want to use BrickOS
with C on the robot to bypass the limitations of the
legos firmware. But I also want to create a GUI to send
initial settings data (not the full program) to the robot
and recieve data after the trial. I would prefer to do
this in windows and was hoping to use Visual basic. I
have seen communication to the brick using the
Spirit.ocx+vb combination, and am wondering if this can
be used to send data to BrickOS firmware. I also saw
the OpCode commands
(http://graphics.stanford.edu/~kekoa/rcx/#Opcodes) to
send data to the RCX and am wondering if that would
work with BrickOS firmware. If so how would I send
these messages to the USB. If none of these would
work, could you possibly suggest another way of
accomplishing my goals.

Thanks in advance.

make fails, assembler errors

Anonymous — Tue, 21 Dec 2004 06:36:13 -0000

during make, I am getting the following assembler error:

fixsfsi.s Assembler messages:
fixsfsi.s:195: Error invalid operands
make[2]: *** [fixsfsi.o] Error 1
make[2] Leaving directory '...

And make crashes.

Before hand, I installed binutils-2.15, and gcc-core-3.4.3.

Using the prefix, I placed everything in /usr/local/

I would be glad to email an instrall transcript

How to generate a continuous signal

Anonymous — Wed, 08 Dec 2004 15:14:03 -0000

Hello,
I am currently trying to implement a communication protocol between
two bricks using just one of the copper wire given with the brick.
The protocol is based on manchester encoding, using a well-timed
alternation of up and low signals.
My problem is : how to generate such signals. I thought in the first time
it would be as easy as plugging a motor plug to a sensor plug.
I would then let the sensor plug be a touch sensor for BrickOs.
For the motor plug, it would really be a motor for Brickos.
But it seems that when you turn on the motor, it does not generate a
continuous signal but something more complicated.
How could i get a continuous signal on this output plug ?

I hop i am posting this to the right place.

crash after download brickos.srec

Anonymous — Wed, 19 May 2004 16:52:07 -0000

Compiling works fine,
but when I try to download the kernel to the RCX it
crashes after I had transmitted 100%.
Afterwards nothing works, I have to pull off the batteries.

Any help??

thx

tools build but demos don't

Eidirsceoil — Sat, 24 Apr 2004 03:12:15 -0000

First off, thanks for making the OS and for looking at
this ;-)

I built gcc-3.3 and binutils 2.13 for the hitachi using
the method in the HOWTO.

I can build the util/ tools for brickOS-0.2.6.10.6 and
the CVS version. However, both versions fail during
the build of the demos, during the makelx invocation.

Here is the output of the makefile for the CVS
version. Essentially the same error is happens in
the other. (gcc, etc., are in /opt/h8300/bin. Spacing
added).
