I am building a toolchain for RTEMS and was informed gcc 4.5.3 is the one. This how-ever does not build with newlib 2.0.0. Which version of newlib is used with 4.5.3 ?
<kiwichris>
Hmm it might be a host issue and not a LM32 issue.
lekernel has joined #milkymist
<Fallenou>
isn't it newlib 1.20 ?
<kiwichris>
It switch at its yearly release Dec 2012
<Fallenou>
let me check which one I'm using
<kiwichris>
It might not be LM32 or newlib, it looks like an issue in libiberty so a host thing
<Fallenou>
can you pastebin your issue ?
<kiwichris>
../../../gcc-4.5.3/libiberty/strsignal.c:554:1: error: conflicting types for 'psignal'
<Fallenou>
OK, I can tell you I'm using gcc 4.5.3 and newlib 1.20 and binutils 2.22
<kiwichris>
Thanks.
<kiwichris>
The error is on MacOS so I am building on Fedora to see what happens.
<Fallenou>
I remember succeeding in compiling lm32 toolchain on Mac OS X 10.6 but I don't remember gcc nor newlib version
<kiwichris>
That error is a host error so I will sort that out, how-ever on Fedora I have a different one...
<Fallenou>
I can say that lm32--netbsd toolchain builds very well under Mac OS X :)
<kiwichris>
lm32-rtems4.11-gcc-4.5.3-newlib-2.0.0-1-4.5.3/gcc-4.5.3/newlib/libc/include/sys/types.h:179:17: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'mode_t'
<kiwichris>
I am sure. This one looks like an issue with header files between RTEMS, newlib and gcc
<wpwrak>
try including sys/stat.h before whatever includes sys/types.h ?
<kiwichris>
We would like to have LM32 on newlib-2.0.0 and as gcc has to be 4.5.3 it is a matter of sorting this out.
<Fallenou>
oh, a libc upgrade, nice :)
<kiwichris>
Yeah that is the intent
<kiwichris>
It would be nice to have LM32 on 4.7.2 but hey that is what happens
<Fallenou>
yes, there has been an attempt as I said in my email
lekernel_ has joined #milkymist
<kiwichris>
Understood.
<Fallenou>
but it proved to be a non trivial task which motivated no one
<Fallenou>
gcc code ... :)
<kiwichris>
:)
<Fallenou>
but please keep us posted on your issues/steps forward
<kiwichris>
I will. It is all captured in the rtems-source-builder.git repo on git.rtems.org. Patches will be public in the rtems-tools.git repo.

If you want to try a build it is about 3 commands.
<Fallenou>
oh, very nice
<Fallenou>
NetBSD has a cool script to build cross toolchains as well :)
