# sudo apt-get install ninja-build

Some of the variables like CFLAGS, CXXFLAGS, LDFLAGS are not empty.
|
|
It is not possible to build ClickHouse with custom flags.
|
|
These variables can be set up by previous invocation of some other build tools.
|
|
You should cleanup these variables and start over again.
|
|
|
|
Run the `env` command to check the details.
|
|
You will also need to remove the contents of the build directory.

Note: if you don't like this behavior, you can manually edit the cmake files, but please don't complain to developers.")
