git-update-cache:

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..
