Hi, I am trying to compile syslog-ng 3.3.4 version on an HPUX HPPA 11.11 machine. The configure options I used were. ./configure --enable-dynamic-linking --prefix=/opt/soe/local/syslog-ng-3.3.4 Compiler options: compiler : gcc -std=gnu99 compiler options : -g -O2 -Wall -pthread -U_XOPEN_SOURCE -U_XOPEN_SOURCE_EXTENDED -D_HPUX_SOURCE -D_REENTRANT -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include -I/opt/soe/local/syslog-ng-3.3.4/eventlog/include/eventlog -I/usr/local/include -I$(top_srcdir)/lib/ivykis/lib/include -I$(top_builddir)/lib/ivykis/lib/include -I$(top_srcdir)/lib/ivykis/modules/include -D_GNU_SOURCE -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 linker flags : -lcl prefix : /opt/soe/local/syslog-ng-3.3.4 linking mode : dynamic __thread keyword : no Submodules: ivykis : internal libmongo-client : internal Features: Debug symbols : no GCC profiling : no Memtrace : no IPV6 support : yes spoof-source support : no tcp-wrapper support : no Linux capability support : no PCRE support : yes Env wrapper support : no systemd support : no (unit dir: none) Modules: Module search path : /opt/soe/local/syslog-ng-3.3.4/lib/syslog-ng Default module list : affile,afprog,afsocket,afuser,basicfuncs,csvparser,dbparser,syslogformat Sun STREAMS support (module): no SSL support (module) : no SQL support (module) : no PACCT module (EXPERIMENTAL) : no MongoDB destination (module): yes JSON support (module) : no (using no) The make though fails with the below error. /bin/sh ../../libtool --tag=CC --mode=link gcc -Wall -g -O2 -o client client.o ../libivykis.la -lpthread libtool: link: gcc -Wall -g -O2 -o client client.o ../.libs/libivykis.a -lpthread /usr/ccs/bin/ld: Unsatisfied symbols: pthread_sigmask (first referenced in ../.libs/libivykis.a(iv_main.o)) (data) pthread_mutex_init (first referenced in ../.libs/libivykis.a(iv_main.o)) (data) pthread_mutex_destroy (first referenced in ../.libs/libivykis.a(iv_main.o)) (data) pthread_mutex_unlock (first referenced in ../.libs/libivykis.a(iv_main.o)) (data) pthread_mutex_lock (first referenced in ../.libs/libivykis.a(iv_main.o)) (data) /usr/ccs/bin/ld: (Warning) Linker features were used that may not be supported in future releases.
