Thanks for your help. I tried to compile the testprogram with "gcc ssl_accept.c -o sslaccept -lssl -lcrypto -L/usr/lib" When executing ./sslaccept I get ./sslaccept: error while loading shared libraries: /usr/lib/libcrypto.so.1.0.0: undefined symbol: H, version efault_method
The shared libarie /usr/lib/libcrypto.so.1.0.0 exists. Something other may be broken? The sslaccept test programm will be executed when I use ./configure to compile some software which is testing if openssl is installed. So I'm not able to change the source of sslaccept. greetings ---------------------------------------- > From: [email protected] > To: [email protected] > Date: Thu, 4 Apr 2013 05:46:03 -0600 > Subject: RE: testprogram results in undefined reference to x > > Wow, that's a lot of output :) > > First of all, you need -lssl and -lcrypto.
