Well, the problem is that if `DH_compute_key_padded ` signature exists in the included openssl header files `cmake` should define `HAVE_DH_PADDED_FUNC`: https://github.com/xrootd/xrootd/blob/253acea4cf51ff221d23e82b0f667a61de562785/cmake/FindOpenSSL.cmake#L85-L89 and then the part of code where you getting your compilation error wouldn't be included in compilation at all. Now the big question is why it sin't ;-) could add check if the cmake `check_function_exists` and `check_symbol_exists` is called and if it finds anything? -- You are receiving this because you are subscribed to this thread.
