Topic: Undefined reference to OPENSSL_sk_num ERR for Apache 2.4.54

[Rose]

Hi all,

I am unable to compile Apache HTTPd-2.4.54 on Linux platform.

My system config:
OS: RHEL 7 - 3.10.0-1160.76.1.el7.x86_64
Openssl: OpenSSL 1.1.1q 5 Jul 2022

I am getting the following error, even when I try with OpenSSL 3x, I am getting the same error.

Please kindly help me.

Commands I used:

[root@abc.com]# export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64:$LD_LIBRARY_PATH
[root@abc.com]# systemctl stop apache2.service
[root@abc.com]# ./configure --prefix=/app/Apache2.4 --enable-mods-shared=all --enable-ssl --with-ssl=/usr/local/bin/openssl --enable-so --with-openssl=/usr/local/bin/openssl
[root@abc.com]# Make & make test
