Is there a missing step to create fontdesign.exe?

You can do make fontdesign in the util directory to create fontdesign.exe
I have managed to get brickos-0.2.6.10 working using gcc 3.3.1 on win98 under
cygwin, though I had a few problems along the way. At this stage I have only
tried a few of the demo programs, and do not have c++ support as I neglected to
download the g++ source.
Problem 1 - multi line string literals deprecated
and other warnings
As has been noted elsewhere in this thread, you can
manually go through and change all the multi line string literals. After
spending some time doing this, I discovered there is a
patch available to
do it for you, thanks to
this page (see
section 3b). There is also one for the ASM Constant warning. I guess it would
have paid to click around the sourceforge site before diving in!
See also
here - I chose to add the volatile qualifier to the parameters.
Problem 2 -
assembler errors and warnings
I was then getting warnings about operand size
in some of the .s files (fixed by remove .w on affected lines), and an error in
fixsfsi.s. It didn’t like this line (invalid operand I think):
add.b
#-158,r4l ; subtract bias + 31 from exponent
I was able to fix this
by splitting it over two lines (a -127 and a -31) - I guess it figured a signed
byte should be within +/- 127?
After all that, I tried to download the
firmware onto the rcx. It got to 100% complete, and dll exited without error,
but the rcx turned off and I needed to remove a battery to reset it. I repeated
the process a few times with the same result.
Now, in addition to gcc 3.3.1,
I had downloaded the source for the latest binutils that the cygwin setup was
offering me - binutils-20030901-1. All the assembler warnings were making me
suspicious, so I decided to try what the instructions suggested (odd idea I
know!) and use binutils-2.10.1.
The assembler in binutils-2.10.1 compiled all
the .s files without warning or error, and I am now able to download (upload?
transfer?) firmware and programs to the rcx. Now, to build a robot to fetch me
beer/coffee!
