Compile error when building Mongocxx driver with gcc-14

Wayne_Xin · 2024-06-21T10:15:36.524Z

We upgraded from gcc-13 to gcc-14 and started to fail building mongocxx driver 3.6.7. Any help would be appreciated. I’m building from the source files downloaded from Mongo Github in .tar.gz format.

linux: ubuntu 20.

Hi @Wayne_Xin

3.6.7 is a 2 year old release and isn’t maintained anymore. Could you give the latest release (3.10.1) a try?

Thanks. I was able to patch the mongodb source to address the error. Using latest code would require more work to change our code to be compatible with newer version.
