[gentoo-embedded] C compiler cannot create executables

[gentoo-embedded] C compiler cannot create executables

[Stephen Feyrer]

[-- Attachment #1: Type: text/plain, Size: 1644 bytes --]

Hi.

I'm still trying to build Dovecot for a Qnap network attached storage
device. Below is my latest attempt.  The significant detail in all of
that is that I'm using libc-2.3.4.so (which I'm borrowing from the nas).
 The thing being that when I have compiled Dovecot against my version of
Glibc it will not run on the nas.

Please help.

Can you build it statically? It will be large of course, but you
should have enough disk space, right?

Impossible to help without more detail. Please provide e.g.
config.log

I'd certainly have enough disc space but it would make it too big to put
in an ipackage though that is not my primary goal.  At this time I don't
actually know how (but with a little help from google, I'm sure I'll
find out).

Sorry, I can only guess at what's going on here (except of cause that it
doesn't work).  I imagine from this excerpt of my config.log that it
should be obvious and staring me in the face.

If this has a specific mean that I should know, please tell me.

Better yet, if there is away making my build environment target the host
system with that version glibc, tell me that instead.

Indeed all I really need to know is how to build a working version of
dovecot for the qnap network attached storage device.

[David Ford]

my apologies for the nearly  blank reply, i was interrupted and needed
to leave quite promptly.

it looks like you have a variance in your toolchain.  did you perhaps
rebuild your toolchain in parts?  try re-emerging your entire arm tool
chain so your headers and libraries match up properly.

Not a problem, life is never straight forward.

you have a mismatch between the glibc files you're importing.  you must 
include all of the libraries from the exact same glibc build, not just one or 
two.

at least my thoughts were in the right direction :)

Thank you.  I hope we're all going in the right direction.

Hi and thanks!

So far the only file which I've taken from the nas is the libc-2.3.4.so
which others should I be looking for?

Hi.

After the careful abuse of a Star Trek Plot, I have managed to
discovered that there are a number of files *-2.3.4.so on the target
machine.

So far I have install all these files into
/usr/armv5tel-softfloat-linux-gnueabi/lib/ .

Thus ./configure has complete properly, then make and make
DESTDIR="qnap-D-1.2.3" install also!

Now the product of this seems to still use Glibc 2.7...  So I'm now
explicitly targeting all the Glibc 2.3.4 libraries.

I'll see how that goes.

That fails in the configure with

configure:4213: armv5tel-softfloat-linux-gnueabi-gcc    conftest.c

I think I must have missed something when copying glibc...  But I don't
know yet.

[gentoo-embedded] C compiler cannot create executables

[Jean-Claude Gervais]

I installed Gentoo on an AMD Geode by chrooting its flashcard hard-disk
on a pentium4 machine.

After installing everything and booting the system, I have exported
the /usr/portage folder on my workstation so the Geode can continue to
emerge programs without being taken offline and chrooted.

But whatever program I try to emerge, the system gives the following
error.

Is this really right?


How was binutils built? Perhaps try a different version.

Try pc instead of gentoo?

Try gnu instead of uclibc?

Nothing wrong with that.. It's a perfectly valid CHOST= combo on Gentoo.

> How was binutils built? Perhaps try a different version.

Good suggestion. binutils-2.18 may be the cause of the problem..

These two would probably be a complete waste of his time/resources.

Re: [gentoo-embedded] C compiler cannot create executables

[Jean-Claude Gervais]

Same problem, different environment:

I produced a cross-development toolkit by using the following command:

.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-
SYSROOT="/usr/arm-softfloat-linux-uclibc"

UCLIBC_CPU="ARM920T" USE="-*" crossdev -v -S --binutils 2.17 --gcc
3.4.6-r2 --kernel 2.6.19-r2 --libc 0.9.28.3 --ex-gdb --target
arm-softfloat-linux-uclibc
.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

This went well; all the required tools were built.

But now when I try to use the (modified) xmerge script, I get the
"C compiler cannot create executables" error

Here is my modified xmerge script:
.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-
#!/bin/bash
SYSROOT="/usr/arm-softfloat-linux-uclibc"
export SYSROOT
CBUILD=$(portageq envvar CHOST)
PORTAGE_CONFIGROOT="$SYSROOT"
if [[ "$1" == "--root" ]] ; then
    ROOT="$2"
    shift 2
else
    ROOT="$SYSROOT"
fi
export CBUILD PORTAGE_CONFIGROOT ROOT

emerge $*
.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

My questions are these;

Should I have other variables set beforehand? Could that explain the
problem?

Why does the compiler seem to work when invoked to retrieve its version
but not to actually compile?

Thanks.

This doesn't look right.  Did you setup ${SYSROOT}/etc/make.conf and
${SYSROOT}/etc/make.profile ?

This line should be:
CHOST="arm-softfloat-linux-uclibc"

OK, I changed that line, performed a 
crossdev -C arm-softfloat-linux-uclibc

And then re-ran the toolchain build procedure I am using;

SYSROOT="/usr/arm-softfloat-linux-uclibc"

UCLIBC_CPU="ARM920T" USE="-*" crossdev -v -S --binutils 2.17 --gcc
3.4.6-r2 --kernel 2.6.19-r2 --libc 0.9.28.3 --ex-gdb --target
arm-softfloat-linux-uclibc

Which concluded with no errors.

However, when I run any xmerge, I still get the same error
"C compiler cannot create executables"

I have no idea what I am missing, surely something small, but I am
clueless.

Thanks.

judging by your initial ncurses build error, you haven't successfully
xmerge'd anything into SYSROOT, so all you had to do was change CHOST in
${SYSROOT}/etc/make.conf, then try xmerge ncurses again.

crossdev doesn't use SYSROOT, it creates it.  So there is no need to set it.

Did you repeat Section 3 of the cross-development guide after blowing
away SYSROOT with crossdev -C <target>?  And set CHOST correctly?

Yes, absolutely.

You mean in /usr/arm-softfloat-linux-uclibc/etc/make.conf ?
Yes.

The make.conf at that location is

ACCEPT_KEYWORDS="arm"
ARCH="arm"

CFLAGS="-Os -pipe -mfloat-abi=softfp -mfpu=vfp"
CHOST="arm-softfloat-linux-uclibc"
CXXFLAGS="${CFLAGS}"

Okay, I suspect you fixed the error you were getting before
(configure:1286: result: i686-softfloat-linux-uclibc), so let's take a
look at the config.log again and see what's tripping it up this time.

thx,

Eureka! Or maybe I should say D'OH!

I had some invalid compiler options: -mfloat-abi=softfp -mfpu=vfp
in my CFLAGS!

I scanned the config.log too quickly last time. Sorry!

and
