Fresh installation of 2020.02 with the following config: Toolchain -> Enable C++ support -> enabled Build options -> libraries -> static only Target packages -> Libraries -> Database -> leveldb -> enabled From the cmake output of leveldb: -- Looking for snappy_compress in snappy -- Looking for snappy_compress in snappy - not found Snappy is being detect correctly when building with shared libraries. This issue wasn't present in buildroot 2019.02.
Applying changes from https://github.com/google/leveldb/pull/686/files seems to fix the detection (and makes the library compatible with existing compresses databases again)
I have submitted Buildroot patches to address this issue: https://patchwork.ozlabs.org/project/buildroot/list/?series=177533 Thanks for your bug report!
These patches have now been merged and are part of 2020.05 and the upcoming 2020.02.3
