Bug 92692 – glibc-2.3.5 fails when being cross-compiled for a native target

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Radek Podgorny 2005-05-15 04:58:54 UTC]

I'm trying to cross-compile the entire gentoo system for my ipaq pda. The cross-tools compiled fine but when I tried to compile the glibc for the target system, if fails with

../sysdeps/unix/syscall.S: Assembler messages:
../sysdeps/unix/syscall.S:28: Error: cannot represent SWI relocation in this object file format

This is caused by gcc sourcing the wrong (build-system, not the target one) asm/unistd.h. It can be effectively solved by modifying src/glibc-2.3.1/Makerules like this:

adding -I/root/ipaq/local/arm-linux/include

so that +sysdep-includes becomes

+sysdep-includes := $(addprefix -I,$(+sysdep_dirs)) -I/root/ipaq/local/arm-linux/include

(the path should be constructed like ${ROOT}/usr/include)

...or maybe there's a better way but this works.

[Comment 1 Jakub Moc (RETIRED) 2005-05-15 06:08:41 UTC]

Have a look at 

http://dev.gentoo.org/~vapier/CROSS-COMPILE-HOWTO

(especially step 9). 

[Comment 2 Radek Podgorny 2005-05-15 07:17:30 UTC]

...yeah, I'm familiar with this howto and it just isn't that simple. Believe me. Vapier may have been lucky if his unistd.h's were compatible (between build and target) but generally, it doesn't work...

[Comment 3 SpanKY 2005-05-15 12:46:26 UTC]

you didnt really post any info on this

if your cross-compiling toolchain is setup properly, it will automatically include the right headers

[Comment 4 Radek Podgorny 2005-05-15 17:37:01 UTC]

Well, how do I verify my cross-toolchain is setup correctly? I assumed a successful crossdev build to be sufficient.

You can try to see for yourself.

crossdev --target arm-unknown-linux-gnu

USE="bootstrap build" CHOST="arm-unknown-linux-gnu" CBUILD="i686-pc-linux-gnu" emerge glibc

...anyway, ask me on any info you need.

[Comment 5 SpanKY 2005-05-15 19:57:10 UTC]

well you still havent posted `emerge info` so how am i supposed to guess at your setup

you yourself in your original report said you built your own cross-compiling toolchain ... nowhere did you say you used crossdev

all that means is that you're trying to do cross-compiling yourself so of course the toolchain ebuilds are going to fail

[Comment 6 Radek Podgorny 2005-05-16 03:09:58 UTC]

Well, I don't know what useful can emerge info be but here it comes:

[Comment 7 Radek Podgorny 2005-05-16 03:16:54 UTC]

Anyway, I've never said I'm using my custom cross-toolchain. I followed your howto (only skipped first 8 steps because crossdev took care of it). When issuing

ARCH=arm CHOST=arm-unknown-linux-gnu CBUILD=i686-pc-linux-gnu USE="bootstrap build" emerge sys-libs/glibc

it fails with the error I've posted earlier.

How do I verify crossdev did a good job when building the cross-toolchain?

[Comment 8 Radek Podgorny 2005-05-16 04:05:41 UTC]

Take a look at http://podgorny.cz/moin/GentooOnIpaq to see what steps I took, please...

[Comment 9 SpanKY 2005-05-16 09:17:30 UTC]

this is why you cant file bug reports with very little information

your original report never mentioned crossdev and in fact contained a link
to instructions on how to build your own cross-compiling toolchain

all you said was 'glibc unable to be cross-compiled' ... well if you ran
`crossdev -t arm-unknown-linux-gnu`, then you already cross-compiled
glibc for the arm target ... just do `ls /usr/arm*/lib/libc*` and you should
get a bunch of arm libraries back
i'm assuming the issue here is that you're trying to do `ROOT=someplace emerge glibc`
and *that* glibc is not cross-compiling properly for the arm target

[Comment 10 Radek Podgorny 2005-05-16 10:09:23 UTC]

Yeah, you got it right. I'm sorry I didn't make myself clear enough in the first place...

[Comment 11 SpanKY 2005-05-16 10:36:45 UTC]

ive documented this issue already here:
http://dev.gentoo.org/~vapier/CROSS-COMPILE-SYSTEM

[Comment 12 Radek Podgorny 2005-05-16 13:43:12 UTC]

OK, so let's solve this one. :-) The problem is in wrong unistd.h being sources. When I look at /usr/arm-u...gnu/sys-include/unistd.h it's not the right file for arm architecture. Is this the file that gets included by default (when no -I is specified)? If yes, it looks like the crossdev did something wrong...

[Comment 13 Eric Toombs 2005-06-03 22:36:27 UTC]

I am also having no end of trouble cross-compiling glibc version 2.3.5 with
crossdev. That is During the initial crossdev toolchain compile not using the
crossdev toolchain. the previous version compiles perfectly. (<glibc-2.3.5) the
error message I got while building a i586-pc-linux-gnu toolchain with an
i686-pc-linux-gnu installation is extremely long so brace yourself. It's a
section of the log that crossdev makes.:

if you need anything else just say so. This is only trivial to my actual
computer development as I can still use the old version so take your time.

[Comment 14 SpanKY 2005-10-12 22:38:54 UTC]

can you sync up to the latest tree and see if this works any better ?

ive had reports of mips64 success ...

[Comment 15 Radek Podgorny 2005-10-13 02:24:12 UTC]

OK, will try ASAP, stay tuned...

[Comment 16 Radek Podgorny 2005-10-13 08:27:46 UTC]

At the first quick try it seems to be working. Hold on for more thorough testing...

[Comment 17 Radek Podgorny 2005-10-16 05:38:50 UTC]

Seems to be working, will reopen if problems appear...
