UDev LFS fails to build 'undefined reference to __secure_getenv

[CD1212]

At the UDev build stage of the (development) book my build failed with:

LINK build/udevd
build/udev-local.a(log.o): In function `log_parse_environment':
log.c:(.text.log_parse_environment+0xb): undefined reference to `__secure_getenv'
log.c:(.text.log_parse_environment+0x31): undefined reference to `__secure_getenv'
log.c:(.text.log_parse_environment+0x57): undefined reference to `__secure_getenv'
log.c:(.text.log_parse_environment+0x7d): undefined reference to `__secure_getenv'

I fixed the issue by replacing:

SECURE = $(shell if nm /lib/libc.so.6 | grep -q " secure_getenv"; \
          then echo yes; fi)

 ifeq "$(SECURE)" "yes"
   SECURE_GETENV = SECURE_GETENV
 else
   SECURE_GETENV = __SECURE_GETENV
 endif

with just

SECURE_GETENV = SECURE_GETENV

Felt I should just let you guys know. Hope I submitted this the right way and it helps you out!

I'm not sure why your system fails. What is the output of:

nm /lib/libc.so.6 | grep " secure_getenv"

from inside the chroot envronment? You should get:

0000000000037d70 W secure_getenv

or similar. It sounds like you are building with an old libc.

CD1212, could you try again with ​http://anduin.linuxfromscratch.org/sources/other/udev-lfs-198-3.tar.bz2 and see if that fixes things please?

Thanks,

Matt.

Hi Matt,

Sorry for not replying sooner. As Bruce suggested, I had not symlinked lib64 to lib which makes perfect sense as to why the original code did not work for me.

I have already compiled UDev in but I am more than happy to upgrade to this version if it helps you?

Thanks for your assistance, sorry I wasted your time! :)

No need to retest, and no time wasted :) I was just wondering if the fixes for a different issue had sorted this out, but it looks like it was unrelated. Glad it's working for you now!
