Hello. I'm getting the error message below when compiling an C++ app with jwt.h on Ubuntu 20.04. ‘RSA_padding_add_PKCS1_PSS_mgf1’ was not declared in this scope; did you mean ‘RSA_padding_add_PKCS1_PSS’ The following libraries are being linked in the project: pthread curl crypto ssl crypto xml2 dl z What is the source of the error and how to solve it?

Seems like the version of libcrypto you use does not export RSA_padding_add_PKCS1_PSS_mgf1.

The usage of RSA_padding_add_PKCS1_PSS_mgf1 has been replaced by RSA_padding_add_PKCS1_PSS in the master branch by this PR.

What version of jwt-cpp are you using? What "crypto" library are you using? Which example/documentation did you follow? What compiler are you using?

Assuming OpenSSL, that function has been there for 12years with 1.1.0.

Sorry, it was my mistake. There was a folder containing pre 1.0.0 OpenSSL headers in the project tree, and this was causing the problem. Just remove the folder and the build was successful. Thanks for the quick response.
