perl build failure

[Phil Blundell]

My eglibc builds are failing in perl with:

| ccache i586-oe-linux-gcc -march=i586 --sysroot=/home/pb/oe/build-meta/tmp-eglibc/sysroots/qemux86 -Wl,-O1  -Wl,--as-needed -o miniperl \

What seems to be happening is that perl is adding -fstack-protector to
CFLAGS but then somehow forgetting to include it during final link of
miniperl.

I see that -fstack-protector is being forced off altogether for uclibc
builds which presumably is why the problem doesn't occur there.  But I
am somewhat baffled as to why this is apparently not happening for
anybody else with eglibc.

Anyway, does anybody have an idea what is going wrong here?  I had a
quick look at it but the perl cross-compilation process seems to be
slightly baroque and I couldn't immediately figure out how the various
makefiles and config fragments were meant to be interacting.

Perl build failure

Hi,

I'm attempting to build the head of the master branch, targeting
core-image-minimal on qemux86 with an up to date Ubuntu 10.04 32-bit system.

I am getting the following error from perl:

/home/welchma/Documents/linux/yocto/yocto_head/build/tmp/work/i586-poky-linux/perl-5.14.2-r2/perl-5.14.2/Cross/generate_config_sh
config.sh-x86-linux >
/home/welchma/Documents/linux/yocto/yocto_head/build/tmp/work/i586-poky-linux/perl-5.14.2-r2/perl-5.14.2/Cross/../config.sh
Unable to open config.sh-x86-linux at
/home/welchma/Documents/linux/yocto/yocto_head/build/tmp/work/i586-poky-linux/perl-5.14.2-r2/perl-5.14.2/Cross/generate_config_sh
line 47.
make: *** [perl] Error 2

looking in the "Cross" folder there is no config.sh-x86-linux, there is
however a config.sh-i586-linux.

Looking into the Makefile that seems to be run I see:

$(TOPDIR)/generate_config_sh config.sh-$(SYS) > $(TOPDIR)/../config.sh

where:

export SYS=$(ARCH)-$(OS)

The run.do_compile script has:

export ARCH="x86"

Which I guess explains why it's getting that value. Looking at the perl
recipe, the do_configure stage creates a config file and I can see that this
exists in build dir and that contains what I believe are the required values:

ARCH = i586
OS = linux

However this doesn't seem to be explicitly referenced by do_compile and
doesn't seem to be referenced by generate_config_sh.

Any ideas?

Martyn
