gcc 3.3.1 for ARM?

It is possible to build gcc 3.3 for ARM, I actively use it. (thumb, big endian)

What problem do you exactly get?

Maybe it's the fact that I'm trying to use 'newlib'.

What C standard library do you use?

I think that's the problem, I never tried compiling newlib. (it should be possible though, but you need to patch some stuff)

I use the one that's with eCos.

I'm in the process of compiling gcc 3.3.1 for ARM. I've been successful compiling 3.3 under Cygwin with Newlib. So I don't think that's the problem. But without any diagnostics it's really hard to help...

These are the steps I use for ARM7TDMI default. It also works for other arm targets changing the respective modifiers. This works under Linux and CygWin with the latest GCC/Binutils/Newlib toolchain (3.3.1/2.14/1.11.0). For MingW32 a lot of online patching is needed, so I don't recommend using it. Beware that there are still some gcc compilation glitches for ARM targets in the GCC 3.3 series.

Binutils: % cd {BINUTILS_BUILDDIR} % {BINUTILS_SOURCEDIR}/configure --prefix={INSTALL_PREFIX}

--target=arm-thumb-elf % make % make install

GCC (compiler only): % export PATH="$PATH:{INSTALL_PREFIX}/bin" % cd {GCC_BUILDDIR} % {GCC_SOURCEDIR}/configure --prefix={INSTALL_PREFIX}

--target=arm-thumb-elf --enable-targets=arm-elf --with-cpu=arm7tdmi

--enable-interwork --enable-multilib --with-newlib --disable-threads

--disable-shared --with-gcc --with-gnu-ld --with-gnu-as --with-stabs

--with-headers={NEWLIB_SOURCEDIR}/newlib/libc/include

--enable-languages=c,c++,java % make all-gcc % make install-gcc

Newlib: % cd {NEWLIB_BUILDDIR} % {NEWLIB_SOURCEDIR}/configure --prefix={INSTALL_PREFIX}

--target=arm-thumb-elf --with-cpu=arm7tdmi --enable-multilib

--enable-interwork --disable-threads --disable-shared --with-gnu-ld

--with-gnu-as --enable-targets=arm-elf % make % make install

GCC (full build now): % cd {GCC_BUILDDIR} % make all % make install

So that's it. It ain't rocket science after all!

Cheers.

I am a hardware engineer and not at all familiar with linux or GNU or Cygwin, etc. I would like to be able to use the tools without having to build them. If anyone wishes to provide binaries for Win2k and/or other versions, I should be able to host them on my web site for others to download. I know I am not the only one to want these tools without having to learn how to build them.

You can download the 3.3 binaries from my website:

Thanks, downloading them right now. Unfortunately, it failed to compile properly on my Cygwin: kept crashing very early during the 'make' of binutils. No idea why... so if you can tell me how you built them (what sources you used, which host gcc version...)

Hmmm. It was quite some time. I guess I've used the options, documented on the page. I've used some 3.0 compiler I think. The one that normally comes with cygwin should do though it does not contain the ADA compiler so you won't get ADA out of your sources if you use that. I have never had problems compiling binutils so I really don't know what went wrong in your case. I wasn't successful in compiling an ARM cross toolset with the coff object format. Some source says it's not supported, some says it is, so I'm a bit confused there. The sources I've grabbed from the gcc and binutils website, respectively. I got the newlib sources from their CVS repository.

Please show us the failure message if you still have them.
