Summary

0002880: Cannot build netsurf against libressl 3.9.2

Description

Hello.
I'm setting up a tiny musl based distro of my own, kfu. I have libressl 3.9.2 installed, compiling netsurf with

$ make TARGET=framebuffer

produces

#####

I've searched a bit for answers and it seems that the types RSA and X509 are opaque types, direct accesses to their member attributes won't work. https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes

Steps To Reproduce

install dependencies + libressl >= 3.9.2
then run

$ make TARGET=framebuffer
