NSAPI plug-ins are typically written using the C programming language. Using the C++ programming language in an NSAPI plug-in raises special compatibility issues.
On Solaris, the server is built using the new C++ 5 ABI. If your shared library uses C++, it must be compiled with Sun Workshop 5.0 or higher. Sun Java Studio 11 or higher is recommended. Do not use the -compat=4 option when compiling and linking a shared library that uses C++. When running in 32–bit mode on Solaris SPARC, the server provides some backward compatibility for the old C++ 4 ABI or Sun Workshop 4.2. This backward compatibility may be removed at some future date. For all new NSAPI plug-ins, use the new C++ 5 ABI or Sun Workshop 5.0 or later versions.
On Linux, Web Server is built using the gcc 3.2 C++ ABI. If your shared library uses C++, compile with gcc 3.2.x. Because of the volatility of the gcc C++ ABI, avoid using C++ in NSAPI plug-ins on Linux.
