Windows switches

Use the following compile and link switches when building shared libraries on Windows.

Visual Studio 2008 on x86

Important: Include the code for extfn_use_new_api() in each UDF library.

compile and link switches

This example is for a DLL containing the my_plus function. You must include an EXPORT switch for the descriptor function for each UDF contained in the DLL.

cl /Zi /LD   /I includefilepath     my_main.cxx my_plus.cxx  /link /map 
/INCREMENTAL:NO -EXPORT:extfn_use_new_api -EXPORT:my_plus  /out:libiqudfex.dll

Example

Environment setup
