One concern is that -Wl,--as-needed requires greater accuracy with the ordering of objects and
libraries as you link. Also, if a package uses a library indirectly, i.e. A uses C via B: A -> B -> C,--as-needed will peel away C and break A unless A explicitly mentions its need for C.
I think ld no longer links against symbols in indirect dependencies.
#include <openssl/evp.h>
int
main()
{
return (int) &EVP_rc4;
}
/usr/bin/ld: /tmp/ccV4cmYY.o: undefined reference to symbol
'EVP_rc4@@OPENSSL_1_1_0'
//usr/lib64/libcrypto.so.1.1: error adding symbols: DSO missing from

collect2: error: ld returned 1 exit status
Thanks,
