Hi,

I am trying to build HDF4 4.2.15 with Intel OneAPI 2023.2.0 and get the following error:

The same issue is also reported in

https://forum.hdfgroup.org/t/help-building-hdf4-with-clang-error-implicit-declaration-of-function-test-mgr-szip-is-invalid-in-c99/7680

Is there any solution for this or can version 4.2.15 only be built if the compiler flag -Wimplicit-function-declaration is set?

Any help is appreciated.

Best regards

Sam

Hi Sam,

Will it be possible for you to use 4.2.16? The issue was fixed there.

Thanks, Binh-Minh
