Compilation on Arch Linux fails with "openssl_hsm_pkey.c:193:5: error: ‘EVP_PKEY_get1_RSA’ is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]"

Hey,

Arch Linux up-to-date amd64, gcc version 14.1.1, and the complete error is this :

You must remove -Wfatal-errors, there are a lot of warnings of deprecated functions after openssl 3

I'm on Ubuntu 22.04. I was drawn here by a similar error, so I ran ./configure CFLAGS='-w' to suppress the warnings. The build process got further, before terminating with:

libtool: compile:  gcc -I. -I../../src/libpki -I.. -DENABLE_ECDSA=1 -D__LIB_BUILD__ -I/usr/include -w -maccumulate-outgoing-args -Werror -Wfatal-errors -Wunused-variable -Wno-switch -DENABLE_ECDSA=1 -I/usr/include/libxml2 -I/usr/include/mysql -DLINUX -w -maccumulate-outgoing-args -Werror -Wfatal-errors -Wunused-variable -MT libpki_openssl_la-pki_id.lo -MD -MP -MF .deps/libpki_openssl_la-pki_id.Tpo -c pki_id.c  -fPIC -DPIC -o .libs/libpki_openssl_la-pki_id.o

If there was a bertter way to "remove -Wfatal-errors" I would be happy to try it. Please just provide those instructions

resolved with

./configure CFLAGS='-w' --enable-extra-checks --enable-composite
make
