[linuxdc-dev] Building a cross compiler for the Dreamcast

[Gregg C L. <dr...@wo...>]

Hello from Gregg C Levine
Apologies for the duel posted message, but I don't know how many of both
groups subscribe to both.
I seem to be having the programming equivalent of Writers Block. I can not
seem to be able to build a working cross compiler for Dreamcast, and its SH4
processor. This would be based on the GCC 3.3,4 sources. That version was
chosen because that's the version supplied with my Slackware 10.0
installation media. The binary utilities would be at version 2.15.90.03, for
the same reasons.

Is anyone on the two lists reasonably familiar with how Slackware builds its
packages to suggest a set of scripts? Naturally this would include an
appropriate libary as well.

Hello from Gregg C Levine
Actually yes I did. And something within the scripts didn't appreciate my
efforts. I posted my efforts to the newgroup. In case you didn't see it
there, I've got a local copy:
>>>>>>>>>>>>
Hello from Gregg C Levine
I did that. I used the default browser for KDE to download that one. Tar
complained so I grabbed it via wget. Extracted it into the /usr/local/src
directory.

I then ran the script for setting things for the SH4. I should have
mentioned, that my
target isn't one of the developer boards from the company, its a Dreamcast
that's
my target.

I then ran the next script, it complained about not having a couple of
variables set.
Same with the crosstool.sh script. I also created a script file to explain
this:
Script started on Thu 16 Sep 2004 12:21:11 AM EDT
root@who4:/usr/local/src/crosstool-0.28-rc35# sh all.sh
Please set TARGET to the Gnu target identifier (e.g. pentium-linux)
root@who4:/usr/local/src/crosstool-0.28-rc35# sh crosstool.sh
Please set PREFIX to where you want the toolchain installed.
root@who4:/usr/local/src/crosstool-0.28-rc35# exit
Script done on Thu 16 Sep 2004 12:23:17 AM EDT

I am some what confused. I did read the documentation pointed to inside the
doc
directory that the README file points to. Also I'd like to have the
crosstool
scripts build Slackware packages. I'm also going to post the output from the
demo-sh4.sh script:
#!/bin/sh
set -ex
TARBALLS_DIR=/usr/local/src/sh4
RESULT_TOP=/opt/crosstool
export TARBALLS_DIR RESULT_TOP
GCC_LANGUAGES="c,c++"
export GCC_LANGUAGES

# Really, you should do the mkdir before running this,
# and chown /opt/crosstool to yourself so you don't need to run as root.
mkdir -p $RESULT_TOP

# Build the toolchain.  Takes a couple hours and a couple gigabytes.
# note: binutils < 2.13 doesn't know about sh4, so don't try building
gcc-2.95
# note: gcc-3.2.3 has ICE compiling glibc for sh4
(http://gcc.gnu.org/PR6954), so
don't try building gcc-3.2.3

#eval `cat sh4.dat gcc-3.3-glibc-2.2.5.dat`    sh all.sh --notest
#eval `cat sh4.dat gcc-3.3-glibc-2.3.2.dat`    sh all.sh --notest
#eval `cat sh4.dat gcc-3.3.2-glibc-2.3.2.dat`  sh all.sh --notest
#eval `cat sh4.dat gcc-3.3.3-glibc-2.3.2.dat`  sh all.sh --notest
#eval `cat sh4.dat gcc-3.4.0-glibc-2.3.2.dat`  sh all.sh --notest
 eval `cat sh4.dat gcc-3.4.1-glibc-2.3.3.dat`  sh all.sh --notest
#eval `cat sh4.dat gcc-3.4.1-glibc-20040827.dat`  sh all.sh --notest

echo Done.
I examined the configuration files for the SH4, and I noticed that its set
for the
generic processor. Would that make a difference?

Hello from Gregg C Levine
Hmm. What I posted there, was a copy & paste from that newgroup posting.
Evidently I did forget to provide a script of what the script does. Here
comes the actual script:

I think that output clarifies my position. And your right. Packages for
Slackware are indeed tarballs, except the makepkg tool adds a script which
adds it to the records of what's installed on the system. Since your tool
says it can make RPM packages, I can convert those to ny Slackware packages.
What I'd really like is a few pointers suggesting where I should go next.

Right.  Quick question: were you logged in as root when you ran that script?
If so, which part of "Don't run all.sh or crosstool.sh as root, it's dangerous"
don't you understand?  I'd be happy to make that message clearer.
If not, hrmf, I'll have to revise my root detection.

First off, let's just get demo-sh4.sh running.  Log in as a non-root
user and try running it (after creating the directory /opt/crosstool
and chowning it to that user).

Hello from Gregg C Levine
That's what it took. I created a non-root user, logged in as him. I then set
ownership on the directories necessary for building the ctoss compiler, and
started it off. It took the same time that your documentation stated, or
around that figure. Now the question is, installing it. How should I do
that?

No need.  It's already installed.  It builds in its final location.
You might consider chown'ing it to root.
