3. Compiling Code

Use hcom4db/build/linux/opengauss/build.sh to compile the code. The following table describes the parameters.

.

Option	Parameter	Description
-3rd	[binarylibs path]	Specifies the `binarylibs` path, which must be an absolute path.
-m	[version_mode]	Specifies the target version to be compiled, which can be `Debug` or `Release` (default).
-t	[build_tool]	Specifies the compilation tool, which defaults to `cmake`.

Run the following command to perform compilation:

[user@linux ]$ sh build.sh -3rd [binarylibs path] -m Release -t cmake

After the compilation is complete, the dynamic library is generated under the hcom4db/output/lib directory.
