Describe the problem A clear and concise description of what the problem is.

Search for existing solutions The Jep build is automatically tested and confirmed to be working in Linux, OS X, and Windows using Travis and AppVeyor. We cannot possibly test every environment so we rely on the community to document any issues and solutions in other environments. Please search for a similar problem and solution on both the mailing list and the existing closed github issues before opening a new issue.

Environment (please complete the following information):

• OS Platform, Distribution, and Version:windows10v2004
• Python Distribution and Version:PyPy 7.3.9
• Java Distribution and Version:17.0.1
• Jep Version:openjdk 17.0.1+12-39
• Python packages used (e.g. numpy, pandas, tensorflow):numpy

Additional context Hi,I'm trying build jep with pypy (compiler is mingw) .But it error: symbol not defined and undefined reference to,What did I missed?Or which compile option I missed and should be add?(sorry,my eng is bad )

Jep embeds CPython in Java through JNI. PyPy is not CPython so Jep does not embed PyPy.
