Yunkai Zhang commented on TS-2504:
----------------------------------
It seems there is a bug in this patch.
1) Our OpenSSL was installed in '/home/a/' DIR, and its library directory is
'/home/a/lib64/'.
2) By using this patch(in the latest master branch), compiles ATS with
following options:
{code}
[root@test79 trafficserver]# cat config.nice
#! /bin/sh
#
# Created by configure
"./configure" \
"--enable-layout=Gentoo" \
"--with-user=ats" \
"--with-group=ats" \
"--with-openssl=/home/a" \
"$@"
{code}
3) From config.log, we can see that it can detect OpenSSL, but didn't use
correct CFLAGS/LDFLAGS to check OpenSSL functions:
{code}
configure:23731: checking for openssl/ssl.h in /home/a
configure:23742: result: yes
configure:23758: checking whether compiling and linking against OpenSSL works
