git-update-cache:

git-update-cache:

[Sam Ravnborg]

While trying to execute:
git-update-cache -- drivers/Kconfig drivers/net/Kconfig net/Kconfig

I receive the following error:
git-update-cache: symbol lookup error: git-update-cache: undefined
symbol: deflateBound


I have fetched a clean tree from kernel.org, and cloned it using
cg-clone.
Modifications are done in the cloned tree and the error is seen when
trying to do a cg-commit (that does the git-update-cache).

When this error is seen a file .git/index.lock is left and next
invocation of git-update-cache faild due to this but deletes the file.
Third invocation show the same error again.

To my best knowledge I have a working zlib installed.

Any help really appreciated!

This is the reason.

For a strange reason when git-update-chache was compiled is was linked
dynamically towards an older libz.so version.
Latest installed is libz.1.2.2 which includes deflateBound.
libz.so.1 points at 1.1.4 which does not.

The solution was to let libz.so.1 point to latest libz.so file.
In my gentoo distribution there seems to be inconsistency
if /lib or /usr/lib is used. That was the root cause.

Back to do some useful stuff..
