[Buildroot] install uClibc daily snapshot failes

[Claus Klein]

Hi all!

I'm not able to build uClibc daily snapshot:

# Host: Linux P3linux 2.6.16.21-0.25-default #1 Tue Sep 19 07:26:15 UTC 2006 i686 i686 i386 GNU/Linux

It seems, the problem is in target:

# Installs run-time libraries
install_runtime:
...
	cd lib && $(TAR)  -cf - *.so.* | $(TAR) -xf - -C $(PREFIX)$(RUNTIME_PREFIX)lib
...
# failes! -:((


This version:
# Installs run-time libraries
install_runtime:
...
	$(TAR) -C lib -cf - $(notdir $(wildcard lib/*.so.*)) | $(TAR) -xf - -C $(PREFIX)$(RUNTIME_PREFIX)lib
...

# works fine; -:) ck

Bye

You don't have "." in your LD_LIBRARY_PATH, do you?
What is your echo $LD_LIBRARY_PATH ?

I checked this alrady.
That is not the problem.

Of course it is.

fix your LD_LIBRARY_PATH, no patch needed.

Hi,

thanks for your help, you are right.

I din't know that the tailing ':' is the same as ':.'

I'm working with OpenSuse 10.1 and I can't find the config file, which writes this LD_LIBRARY_PATH.
While about 2 years working with buildrout I had no problem with my LD_LIBRARY_PATH!

I would like to hear that the Makefile will be changed to my version. 
This works always!


PS: There is no note about LD_LIBRARY_PATH in the buildroot docu!


Bye,

Claus

^: == :$ == :: == :.:
Same for PATH.

.profile, .bashrc and /etc/sysconfig come to mind.

IMO it is hazardous to have CWD in PATH and the same holds true for the
ld lib path. If you can convince anybody else to apply your patch, then
ok, but i will not apply it since this just means that you risk breakage
anywhere else that may trigger trouble like the one you experienced.

I've added checks to dependencies.sh as you may have seen.
Please fix your pathes. Thanks for your understanding and kind regards,
