wolfstudy opened a new issue #8660:
URL: https://github.com/apache/pulsar/issues/8660


   **Describe the bug**
   
   I use the following command to execute cmake, and can't build successfully when LINK_STATIC is ON,
   
   ```
   cmake . -DBUILD_TESTS=OFF \
       -DLINK_STATIC=ON  \
       -DBOOST_ROOT=/usr/local/include \
       -DPYTHON_LIBRARY=/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib \
       -DPYTHON_INCLUDE_DIR=/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
   ```
   
   the error info as follows:
   
   ```

   When  replace`-DLINK_STATIC=ON` with `-DLINK_STATIC=OFF`, we can build successfully.

   We can use the following script to get the location of `PYTHON_LIBRARY` and `PYTHON_INCLUDE_DIR`:
   
   ```
   #!/bin/bash
   set -o errexit
   cd `dirname $0`
   PYTHON_LIB_DIR=$(python -c "import distutils.sysconfig as sysconfig; print(sysconfig.get_config_var('LIBDIR'))")
   PYTHON_VERSION=$(python -c "import platform; print(platform.python_version()[:3])")
   PYTHON_LIBRARY="$PYTHON_LIB_DIR/libpython$PYTHON_VERSION.dylib"
   PYTHON_INCLUDE_DIR=$(python -c "from distutils.sysconfig import get_python_inc; print(get_python_inc())")
   echo "PYTHON_INCLUDE_DIR=$PYTHON_INCLUDE_DIR"
   echo "PYTHON_LIBRARY=$PYTHON_LIBRARY"
   ```
