openssl-1.1.1b: Compilation errors when use async and ct

[Samiya Khanum]

Hi,

While compiling async I see below errors with UCLIBC.



*libcrypto.so: undefined reference to `getcontext'libcrypto.so: undefined
reference to `setcontext'libcrypto.so: undefined reference to `makecontext'*

As UCLIBC doesn't have support to these APIs, i have added no-async in
configure. With no-async below errors are seen.




*libcrypto.so: undefined reference to `ERR_load_ASYNC_strings'libcrypto.so:
undefined reference to `async_init'libcrypto.so: undefined reference to
`async_delete_thread_state'libcrypto.so: undefined reference to
`async_deinit'*

Do we need to have macro check" #ifndef OPENSSL_NO_ASYNC" before these api
calls?

Similarly for CT, we are seeing below errors. With no-ct options,
compilation is OK.

We would like to know what would be the impact if we disable async and ct
features. Could you please help us in understanding these features.
