i noticed that libgetdns.so is being linked against libdl, but i don't think we're using dlopen or any of the other functions exported from ldl. fwict, ./configure is adding -ldl because of m4/acx_openssl.m4, which claims: # openssl engine functionality needs dlopen(). BAKLIBS="$LIBS" AC_SEARCH_LIBS([dlopen], [dl]) if test "$LIBS" != "$BAKLIBS"; then LIBSSL_LIBS="$LIBSSL_LIBS -ldl" fi However, we're not using OpenSSL Engine support directly. If some library user wants to initialize openssl's engine support, they should be able to do that with OpenSSL itself, and then they should be able to get libcrypto and/or libssl to use libdl directly. On some minimal systems, libcrypto and libssl might be built without engine support at all; in that case, libgetdns is adding a superfluous dependency to the linker. I don't know the what the getdns policy is about tweaking the files in m4/, but maybe the following patch can be safely applied? |
