This was apparently somewhat recent - here is the OpenBSD ticket regarding it:
http://sourceforge.net/p/levent/bugs/320/ If someone feels it important that we continue supporting OpenBSD, one might explore the solution recommended in that ticket. It's also possible that the libevent guys are working on solving it too (or may have already done so in a later version than we include) On Aug 1, 2014, at 4:07 PM, Paul Hargrove <phhargr...@lbl.gov> wrote: > I am seeing the following on OpenBSD/amd64 with "make V=1": > > Making all in tools/wrappers > /bin/sh ../../../libtool --tag=CC --mode=link gcc -std=gnu99 -g > -finline-functions -fno-strict-aliasing -pthread -export-dynamic -o > opal_wrapper opal_wrapper.o ../../../opal/libopen-pal.la -lutil -lm > libtool: link: gcc -std=gnu99 -g -finline-functions -fno-strict-aliasing > -pthread -o .libs/opal_wrapper opal_wrapper.o -Wl,-E -L../../../opal/.libs > -lopen-pal -lpthread -lutil -lm -pthread > -Wl,-rpath,/home/phargrov/OMPI/openmpi-1.8.2rc3-openbsd5-amd64/INST/lib > ../../../opal/.libs/libopen-pal.so.8.0: warning: vsprintf() is often misused, > please use vsnprintf() > ../../../opal/.libs/libopen-pal.so.8.0: warning: strcpy() is almost always > misused, please use strlcpy() > ../../../opal/.libs/libopen-pal.so.8.0: warning: random() isn't random; > consider using arc4random() > ../../../opal/.libs/libopen-pal.so.8.0: warning: strcat() is almost always > misused, please use strlcat() > ../../../opal/.libs/libopen-pal.so.8.0: warning: sprintf() is often misused, > please use snprintf() > ../../../opal/.libs/libopen-pal.so.8.0: undefined reference to > `arc4random_addrandom' > collect2: ld returned 1 exit status > *** Error 1 in opal/tools/wrappers (Makefile:1623 'opal_wrapper') > *** Error 1 in opal (Makefile:2145 'all-recursive') > *** Error 1 in /home/phargrov/OMPI/openmpi-1.8.2rc3-openbsd5-amd64/BLD > (Makefile:1689 'all-recursive') > > Ignoring OpenBSD's typical warnings about functions their developers don't > like there is an undefined reference to arc4random_addrandom.
