27 | // ONNX_API is a macro that, depends on whether you are building the |
28 | // main ONNX library or not, resolves to either ONNX_EXPORT or |
29 | // ONNX_IMPORT. |
30 | // |
31 | // This is used in e.g. ONNX's protobuf files: when building the main library, |
32 | // it is defined as ONNX_EXPORT to fix a Windows global-variable-in-dll |
33 | // issue, and for anyone dependent on ONNX it will be defined as |
34 | // ONNX_IMPORT. ONNX_BUILD_MAIN_LIB can also be set when being built |
35 | // statically if ONNX is being linked into a shared library that wants |
36 | // to export the ONNX APIs and classes. |
37 | // |
