Subject: ldns/host2str.c: fix build error with SSL disabled
X-Git-Tag: release-1.7.1-rc1~52
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a2ecd64c9dd9831335bb5de50ef02488e78092d2;p=thirdparty%2Fldns.git

ldns/host2str.c: fix build error with SSL disabled

If --without-ssl option is given, the following error applies:

===
./host2str.c:2017:74: error: unknown type name 'BIGNUM'
ldns_print_bignum_b64_line(ldns_buffer* output, const char* label, const BIGNUM* num)
                                                                         ^
./host2str.c:2025:11: warning: implicit declaration of function 'BN_bn2bin' is invalid in C99 [-Wimplicit-function-declaration]
                int i = BN_bn2bin(num, bignumbuf);
===

With that, ldns_print_bignum_b64_line() should be wrapped into HAVE_SSL ifdef.
