Subject Re: [users@httpd] undefined reference to tls client method
Date Sat, 30 Nov 2013 12:51:56 GMT
Hi David,

I have exactly the same problem on CentOS-5.10 with openssl1.0.1e. It seams
you are indicating your openssl installation from source went wrong
somewhere. This is how I compiled and installed openssl from source:

$ ./Configure --prefix=/usr/local --openssldir=/usr/local/openssl
enable-tlsext linux-x86_64 threads zlib enable-idea enable-rc5 enable-mdc2
enable-ec shared
$ make depend
$ make
$ sudo make install

still apache ab tool seams linking to wrong library during compile although
I have given --with-ssl=/usr/local/openssl as location in the configure
step. Can you provide more details on how did you exactly solve the problem?
