Fail to build

[wangyuyue]

Dear developers,
I failed quickly when building the project.
Here is the output I get:

node0:~/work/CacheLib> ./contrib/build.sh -T

Could you help me solve this? Thanks in advance.

This will be fixed in a day or two when #200 lands in main, till then, you can edit this file and replace

CacheLib/contrib/build-package.sh

Line 178 in 9447a8a

external_git_branch=release

with

external_git_tag=8420502e

Thanks for your kind reply, it works.
Another question. I think CacheLib is used to provide cached data to other applications. So when the handler provided by CacheLib is not used anymore, how does the application notify Cachelib that it finishes working with the handler and how does Cachelib collect the garbage memory allocated for the temporary object?
