Re: Compiling curl 8.0.1 with OpenSSL 3.1.0 - ../lib/.libs/libcurl.so: undefined reference to ...

well that is a flag used by libcurl and that it reads in from
openssl/macros.h and which one cannot set in the build anyway because I see
on the macros.h file that it first unsets it before it does a long ifdef
dance to determine weather to set it or not

/usr/include/openssl/macros.h :

# undef OPENSSL_NO_DEPRECATED_3_0
# undef OPENSSL_NO_DEPRECATED_1_1_1
# undef OPENSSL_NO_DEPRECATED_1_1_0
# undef OPENSSL_NO_DEPRECATED_1_0_2
# undef OPENSSL_NO_DEPRECATED_1_0_1
# undef OPENSSL_NO_DEPRECATED_1_0_0
# undef OPENSSL_NO_DEPRECATED_0_9_8

# if OPENSSL_API_LEVEL >= 30000
# ifndef OPENSSL_NO_DEPRECATED
# define OSSL_DEPRECATEDIN_3_0 OSSL_DEPRECATED(3.0)
# define OSSL_DEPRECATEDIN_3_0_FOR(msg) OSSL_DEPRECATED_FOR(3.0,
msg)
...
