undefined reference error in compiling about jwt-cpp HOT 9 CLOSED

What version of jwt-cpp are you using?

from jwt-cpp.

0.6.0 thanks for your reply @prince-chrismc

from jwt-cpp.

🤔 hmm are you sure about that version of openssl is the one being pulled into your build scripts and being linked against?
I've not used devtoolset-9 but perhaps it has a never version? You could run scl enable devtoolset-9 "openssl --version" to check.

I wanted to double check the docs but I am only getting a 404 https://www.openssl.org/docs/man1.0.2/man3/EVP_MD_CTX_destroy.html

This should be the correct logic, in 1.1.0 they changed everything to free

You can check the CI but we compile from source and test each one

from jwt-cpp.

i used the command scl enable devtoolset-9 "openssl --version"
it returns OpenSSL 1.0.2k-fips 26 Jan 2017.

from jwt-cpp.

more info
if i use auto verify = jwt::verify().allow_algorithm(jwt::algorithm::hs512{jwt_secret}).with_issuer("auth0"); in my project, it compiles OK.
but i add the other verify = jwt::verify().allow_algorithm(jwt::algorithm::rs256(private_key, "", "", ""))
.with_issuer("auth0"); in my project, then it returns undefined reference error by compiler.

I think it may related to rs256 algorighm?

Can you comment out the library code and print OPENSSL_VERSION_TEXT https://www.openssl.org/docs/manmaster/man3/OPENSSL_VERSION_NUMBER.html

How are you linking to OpenSSL? What build system are you using?

from jwt-cpp.

I think it may related to rs256 algorighm?

Yes the cryptographic keys use the evp context, the hmac is very basic (and insecure) so it doesn't use APIs that have changed

from jwt-cpp.

seems like i use openssl 1.1.0 version for linker but i have another openssl 1.0.2 version installed on my machine.

I highly recommend using a package manager to manage 3rd party dependencies.

Unfortunately there is jot much I can , I will mark this as closed. Bestnof luck!
