 Description   

I hit a problem while building current MaxScale 23.02 from GitHub source on Ubuntu 20.04. Every time I get linking error like this:

I followed the steps in Quickstart from Building MariaDB MaxScale from Source Code to install it.

git clone https://github.com/mariadb-corporation/MaxScale
 
mkdir build
 
cd build
 
../MaxScale/BUILD/install_build_deps.sh
 
cmake ../MaxScale -DCMAKE_INSTALL_PREFIX=/usr
 
make

Managed to reproduce this. There's some auto-detection of libraries going on that aren't linked to MaxScale but are linked to the nosqlprotocol.

Comment by markus makela [ 2023-09-21 ]

This can be fixed by adding -DENABLE_SNAPPY=OFF to the CMAKE_ARGS in cmake/BuildMongoCDriver.cmake.

Comment by Xiaotong Niu [ 2023-09-25 ]

I found another way to fix the problem:

Add "snappy" in the target_link_libraries of the MaxScale/server/modules/protocol/NoSQL/CMakeLists.txt and the MaxScale/server/modules/protocol/NoSQL/test/CMakeLists.txt.

I would like to ask why we don’t use this method to make the link successful, but add -DENABLE_SNAPPY=OFF?

I'm new to this, looking forward to your reply.

The snappy dependency isn't needed which is why it's better to disable the linking instead of adding an unnecessary dependency to MaxScale.

Thank you very much~
