Anyone been able to build armeb-unknown-linux-uclibcgnueabi with GCC 4.4.x yet?

[Joachim Nilsson]

Hi everyone!

Has anyone in the community been able to build armeb toolchains from gcc 
4.4.x yet?

I've been having a lot of problems with that lately (using the tip of 
the hg repo).  Everything seems to work out fine when I build the 
little-endian arm toolchain, but with big-endian it looks like the 
various configure scripts in the gcc tree are having problems when 
building the conftest.c snippets.

My host is a simple little-endian Core2Duo (T61 ThinkPad) and the target 
obviously builds a big-endian libgcc ...

The below example is when building libgomp. If I add --disable-libgomp I 
get to the next lib and get the exact same result, all the way even onto 
libstdc++.

Regards
  /Joachim

It builds fine here using the 'default' branch of the repository. Bails
out when build ltrace (and strace IIRC), but the binutils+gcc+uclibc
part just builds, see log below.

# ct-ng show-armeb-unknown-linux-uclibcgnueabi
    OS            : linux-2.6.32.2
    binutils      : binutils-2.19.1
    C compiler    : gcc-4.4.2 (C,C++)
    C library     : uClibc-0.9.30.1
    GMP/MPFR      : gmp-4.3.1 / mpfr-2.4.1
    PPL/CLOOG/MPC : ppl-0.10.2 / cloog-0.15.7 / mpc-0.7
    Tools         : sstrip dmalloc-5.5.2 duma-2_5_15 gdb-6.8

Changes from the sample currently in the repository:
 - use linux-3.6.32.2 headers (instead of 2.6.31.1)
 - use gcc-4.4.2 (instead of 4.3.2)
 - disabled Fortran and Java, and ltrace/strace/libelf

.config is attached, if you want to give it a spin...

Note: in Mercurial terminology, 'tip' is the latest changeset, not
necessarily on the 'default' branch. I guess you meant:
  "using the default branch of the repository"

You can check with:
# hg id -b    (or: hg branch)
default

# ct-ng version
This is crosstool-NG version hg_default@1667_a5020a1facff

Then it fails with ltrace, as some syscalls (ptrace-related) are missing,
or have changed name, or whatever I still have to check for.

Thank you for you patience, I did not know that about hg. I've reverted 
all changes I've made, rebuilt crosstool and now have that same version 
from the default branch.

It seems you are correct, as always. ;-)

If I build on the Ubuntu 9.04 x86_64 server at my office everythings 
works like a charm.  But on my ThinkPad running Ubuntu 9.10 i686 
(i486-linux-gnu) desktop the exact same build fails (see below).  
Remains to find out what is causing this.  Maybe it's the host gcc 
(Ubuntu 4.4.1-4ubuntu8) or some older toolchain in my PATH -- or could 
it have something to do with the 64-bit vs 32-bit situation?

Good, then, we're on the same grounds.

Oh, don't say that! It happens that I am not. And then I learn! :-)

Hmmm. It used to work a little while back on my i686 machine. As it is
much slower than my x86_64, I don't always test on it. I'll do it today
to see if I can reproduce it.

Also, having a prevoius toolchain in the PATH may indeed be an issue.
That would require proper handling in crosstool-NG, though, as it is
perfectly reasonable to build a new toolchain to upgrade an existing
one...

I can reproduce it as well on my i686 Debian Lenny. Seems gcc barfs
somewhere when run on i686, but does not when run on x86_64.
And I do not have an old toolchain in the PATH.

Unless you beat me to it, I'll check a bit later when I have enough
bandwidth...

Seems like:      http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42081
which points to: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16350

I'm testing a fix, but as the machine (netbook) is slow as hell, it may
take a bit of time...

This really seems to be GCC bug 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41818 which can be worked 
around using --disable-shared in CT_CC_EXTRA_CONFIG.

The referenced patch, with some slight modification, is actually useful 
for big-endian Arm -- even though it didn't turn out to be much help 
with this particular bug.  See the attached revised patch by Lennert 
Buytenhek for details.

Also, while researching this bug I found several binutils 2.20 related 
patches in the OpenEmbedded camp which might be interesting to include 
in crosstool-NG.

Since I've gotten the big-endian Arm toolchain to build now on 32-bit 
(using --disable-shared) I will start testing the patched binutils in 
real-life.  I'll get back to the list with further updates.
