Bug 1263

NSC also fails, so it's either something broken on FreeBSD side or SConstruct and waf don't support FreeBSD well.

$ ./build.py
# Build NSC
Entering directory `nsc'
 =>  /usr/local/bin/python scons.py
scons: Reading SConscript files ...
OSError: Unsupported architecture, if you want to crosscompile, use "scons target=x86" (or amd64):
  File "/usr/home/vedranm/ns-3-allinone/nsc/SConstruct", line 155:

  File "/usr/home/vedranm/ns-3-allinone/nsc/scons-local-1.2.0.d20090223/SCons/SConf.py", line 647:
    ret = apply(self.test, (context,) +  args, kw)
  File "/usr/home/vedranm/ns-3-allinone/nsc/SConstruct", line 69:
    raise OSError, ('Unsupported architecture, if you want to '
Checking target architecure...# Build NSC: failure (ignoring NSC)
Leaving directory `nsc'

OK, this seems very easy. FreeBSD uses name 'amd64' for 'x86_64'. On nsc side this can be patched like:

Haven't tested much else.

That patch is reasonable.

This is a bit nasty. I don't have a current FreeBSD box at the moment... Maybe I can setup a virtual machine to test this.

In the mean time, it may be reasonable to disable NSC on this architecture in the ns-3 WAF build.

I will have one working VM soon. If you want to test this, I can mail you the details.

Something like this is enough to make ns-3 configure pass (NSC will not be enabled since it hasn't been built):

         conf.check_nonfatal(mandatory=True, lib='dl', define_name='HAVE_DL', uselib_store='DL')

However we need to think if 'freebsd9' should be something like 'freebsd7', 'freebsd8', 'freebsd9'.

Thanks, I pushed a similar patch.  This should fix the ns-3 part of the problem, so I am closing the bug report.  Open a similar bug report for NSC directly, if needed.
