[Kamailio-Users] Compiling nonce.o (Auth Module) with TLS=1 fails

Hello all, I am trying to compile kamailio 1.5.3 with TLS=1. The whole kamailio package compiles just fine, with the exception of nonce.o: gcc -fPIC -DPIC -g -O9 -funroll-loops -Wcast-align -Wall -minline-all-stringops -falign-loops -ftree-vectorize -mtune=prescott -Wold-style-definition -Wmissing-field-initializers -Wredundant-decls -DMOD_NAME='"auth"' -DNAME='"kamailio"' -DVERSION='"1.5.3-tls"' -DARCH='"i386"' -DOS='"linux"' -DCOMPILER='"gcc 4.0.2"' -D__CPU_i386 -D__OS_linux -D__SMP_yes -DCFG_DIR='"/usr/local/etc/kamailio/"' -DPKG_MALLOC -DSHM_MMAP -DUSE_IPV6 -DUSE_MCAST -DUSE_TCP -DDISABLE_NAGLE -DHAVE_RESOLV_RES -DSTATISTICS -DCHANGEABLE_DEBUG_LEVEL -DUSE_LOCAL_ROUTE -DF_MALLOC -DUSE_TLS -DFAST_LOCK -DADAPTIVE_WAIT -DADAPTIVE_WAIT_LOOPS=1024 -DHAVE_GETHOSTBYNAME2 -DHAVE_UNION_SEMUN -DHAVE_SCHED_YIELD -DHAVE_MSG_NOSIGNAL -DHAVE_MSGHDR_MSG_CONTROL -DHAVE_ALLOCA_H -DHAVE_TIMEGM -DHAVE_EPOLL -DHAVE_SIGIO_RT -DHAVE_SELECT -I/usr/local/ssl/include -I/usr/local/include -I/usr/include/openssl -c nonce.c -o nonce.o In file included from /usr/include/openssl/evp.h:84, from /usr/include/openssl/x509.h:67, from /usr/include/openssl/ssl.h:177, from ../sl/../../tls/tls_config.h:34, from ../sl/../../version.h:29, from ../sl/../../sr_module.h:54, from ../sl/sl_api.h:33, from auth_mod.h:39, from nonce.c:40: /usr/include/openssl/md5.h:105: error: conflicting types for âMD5_CTXâ ../../md5.h:42: error: previous declaration of âMD5_CTXâ was here nonce.c: In function âcalc_nonceâ: nonce.c:116: warning: passing argument 1 of âMD5Initâ from incompatible pointer type nonce.c:126: warning: passing argument 1 of âMD5Updateâ from incompatible pointer type nonce.c:128: warning: passing argument 1 of âMD5Updateâ from incompatible pointer type nonce.c:129: warning: passing argument 2 of âU_MD5Finalâ from incompatible pointer type make: *** [nonce.o] Error 1 Do you guys have any hints on what is going wrong?
