[Turnserver-devel] Linking error

[Youness A. <you...@co...>]

Hi,

I'm currently on Fedora 14 and turnserver 0.4 does not build correctly on it. 
The error is at link time and it gives me :

/usr/bin/ld: tls_peer.o: undefined reference to symbol 'ERR_reason_error_string'
/usr/bin/ld: note: 'ERR_reason_error_string' is defined in DSO 
/lib/libcrypto.so.10 so try adding it to the linker command line
/lib/libcrypto.so.10: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

After a bit of googling, I found this explanation here :
http://fedoraproject.org/wiki/UnderstandingDSOLinkChange

To fix it, I just had to add
AC_CHECK_LIB(crypto, ERR_reason_error_string,,[echo -e "\tPlease install 
libssl-dev";exit])
in the configure.ac, right after
AC_CHECK_LIB(ssl, SSL_new,,[echo -e "\tPlease install libssl-dev";exit])

This way, it will link with -lcrypto
Let me know if you want an actual patch to apply or this one-line change is fine.

Thanks for patching it for the next version!
Youness.
