BRITE libdl requirement a problem for FreeBSD
Last modified: 2014-06-16 00:47:01 EDT
When BRITE is built for ns-3 under FreeBSD, it is successfully built, but then ns-3's './waf configure' fails: Checking for BRITE location : ../BRITE (guessed) Checking for library dl : not found The configuration failed (complete log in /usr/home/buildslave/scratch/ns-allinone-3.20.rc3/bake/source/ns-3.20/build/config.log) This is because BRITE's wscript adds this: if bld.env['BRITE'] and bld.env['DL']: module.uselib = 'BRITE DL' but FreeBSD doesn't have libdl-- dynamic loading is part of its libc. The workaround for ns-3.20 is to disable the BRITE build for FreeBSD (since this is a lesser-used library): diff -r 8d78e295f29f bakeconf.xml --- a/bakeconf.xml Fri Jun 13 16:13:16 2014 -0700 +++ b/bakeconf.xml Sun Jun 15 20:54:59 2014 -0700 @@ -899,6 +899,7 @@ </source> <build type="make" objdir="no"> <attribute name="no_installation" value="True"/> + <attribute name="supported_os" value="linux;linux2;darwin"/> </build> </module> but a better solution will be to remove the above change to bakeconf.xml and make waf suppress checking for DL when it is on a FreeBSD system.
