Hello everyone,
I'm building a minimal distribution for a x86 machine (my host is a x86-64
with CentOS 4.4):
OE Build Configuration:
BB_VERSION = "1.8.12"
METADATA_BRANCH = "org.openembedded.dev"
METADATA_REVISION = "a8a23e995d108ecdfc31129941671551c591bc6e"
TARGET_ARCH = "i486"
TARGET_OS = "linux"
MACHINE = "x86"
DISTRO = "minimal"
DISTRO_VERSION = ".dev-snapshot-20090310"
TARGET_FPU = ""
During kernel building, I got the following error:
OTE: package linux-2.6.28: started
NOTE: package linux-2.6.28-r6: task do_package: started
ERROR: Error in executing:

Someone else also saw this problem. Search the archives. Its most
probably your host.

Hi,
I searched without success. I agree with you, there is a problem on my host,
but I'd like to know why it pops out during the do_package task.
Any help will be appreciated.
Regards,
Piero

Maybe, that increasing the numbers of max. file handles and number of max.
inodes might help you:
/proc/sys/fs/file-max
/proc/sys/fs/inode-max

Hello.
I had the same problem. It's inside classes/kernel.bbclass:298
(reproduced below):
python populate_packages_prepend () {
def extract_modinfo(file):
import tempfile, os, re
tempfile.tempdir = bb.data.getVar("WORKDIR", d, 1)
tmpfile = tempfile.mkstemp()[1]
cmd = "PATH=\"%s\" %sobjcopy -j .modinfo -O binary %s %s" % (bb.data.getVar("PATH", d, 1), bb.data.getVar("HOST_PREFIX", d, 1) or "", file, tmpfile)
os.system(cmd)
f = open(tmpfile)
l = f.read().split("\000")
f.close()
os.unlink(tmpfile)
tempfile.mkstemp() is used to create a temporary file. This function
return a tuple with an OS file descriptor and a filename. Filename is
stored in "tmpfile" but descriptor is not stored anywhere, but it is
still open because it's only an integer to python so it is not closed at
the end of the function.
For each iteration in which this function is called, a new OS file
descriptor is opened, but not closed. The solution is to store the file
descriptor and close it:
python populate_packages_prepend () {
def extract_modinfo(file):
import tempfile, os, re
tempfile.tempdir = bb.data.getVar("WORKDIR", d, 1)
tf = tempfile.mkstemp()
tmpfile = tf[1]
cmd = "PATH=\"%s\" %sobjcopy -j .modinfo -O binary %s %s" % (bb.data.getVar("PATH", d, 1), bb.data.getVar("HOST_PREFIX", d, 1) or "", file, tmpfile)
os.system(cmd)
f = open(tmpfile)
l = f.read().split("\000")
f.close()
os.close(tf[0])
os.unlink(tmpfile)
There's a patch attached. As Iḿ new to git, I don know it it was created
in the right way. Used command following:
git format-patch cab70860b89f0fd856c5de1c37c6a3d31fd3cc9d --stdout classes >kernel.bbclass.patch

we do not have to worry about cleaning it up once it is closed.
