Re: [ts-7000] Using crosstools-0.43 to build gcc-3.3.4 glibc-2.3.2?

Ok, thanks.

I built the Linux version of the tools last night.

They didn't get built with the suffix, so I guess crosstools-0.43
(sorry, the latest is not -0.48, my bad) just named things
differently than the version TS used (which I think was -0.28).

For anyone else trying this, I had two errors while building
under Linux. The first was that I had to undefine LD_LIBRARY_PATH
as glibc does not like it to be set during a build, and then
I got the following error on completion of the build;

...
Cross-toolchain build complete. Result in 
/opt/crosstool/gcc-3.3.4-glibc-2.3.2/arm-unknown-linux-gnu.
+ exit 0

hello.c: In function `main':
hello.c:4: error: `PATH_MAX' undeclared (first use in this function)
hello.c:4: error: (Each undeclared identifier is reported only once
hello.c:4: error: for each function it appears in.)
 crosstool-0.43]$ date

 crosstool-0.43]$

So it looks like the hello world test was looking for PATH_MAX
but couldn't find it. I didn't look into it yet, but I'm not
too worried, the tools should be fine.

I built the Linux tools under Centos 4.1 (which is the community
version of Red Hat Enterprise 4.1), a 2.6-kernel system.

The Cygwin build needed bison, so I updated my Cygwin to the latest,
and picked up bison (and I had previously added flex and yacc for a
LPC2000 ARM microcontroller arm-elf-gcc build, so you might
need that too). The crosstool-0.43 demo-arm.sh script ran
without errors after that.

I'll build the ts11 kernel later and post results on that.

Thanks!
Dave
