build.py problems

[Johnny]

Hello everybody,
I am new to Cygwin and NS3. I am running Windows 7 with the latest
version of Cygwin and NS3 version ns3.10. I have Cygwin and NS3
installed but when I try to run build.py, I get the following error
message:

$ ./build.py

I have search the web for solutions and found some suggestions to run
rebaseall as fix. I have no success. I have tried the following
sequences of commands but did not fix my problem.

C:\> cd cygwin\bin

$ /usr/bin/ rebaseall

/ur/lib/cygicudata.dll; skipped because nonexistent
/ur/lib/cygicuil8n.dll; skipped because nonexistent
/ur/lib/cygicuio.dll; skipped because nonexistent
/ur/lib/cygicule.dll; skipped because nonexistent
/ur/lib/cygiculex.dll; skipped because nonexistent

FixImage (/usr/x86_64-w64-mingw32/sys-root/mingw/bin/
libgcc_s_sjlj-1.dll) failed
With las error = 13



After I ran rebaseall, I tried to run build.py and got the original
problem as explained above.


Any help would be appreciated.

Thanks,
Johnny

It seems that build.py is not properly detecting that you are on a
Windows machine. It should disable the build of nsc since nsc is not
supported on Windows (it is an optional ns-3 component).

This snippet of build.py is supposed to detect the platform; I'm not
sure why, though, because I thought that win32 would catch both 32- and
64-bit Windows:

elif sys.platform in ['darwin', 'win32']:
print "# Skip NSC (platform not supported)"

As a workaround, you can pass the "--disable-nsc" option to build.py and
it will skip it. I am not sure whether you will next hit this issue
with recent Cygwin:
http://www.nsnam.org/wiki/index.php/Troubleshooting#Cygwin

If you can figure out a more robust way for us to detect your platform,
let me know. Also, I am curious whether you will get past the above
issue in the wiki; if so, can you let me know what version of Cygwin works?

Thanks Tom,

I attempted to disable the NSC with the following sequence of commands
and it return a list of commands and options and an error at the end.

~/ns-allione-3.10/ns-3.10
$./waf configure --disable-nsc

waf [command] [options]

.
.
.
.

waf: error: no such option: --disable-nsc


I am new to Cygwnin and not sure if this is the right directory to
disable NSC.

Any help would be appreciated.

Thanks,
Johnny

Try passing the --disable-nsc to build.py instead. Or, if you are in the
ns-3.10 directory, you should just be able to try "./waf --configure" and
if NSC has not been built, waf should pick it up.

build.py is a separate python program in the ns-allinone-3.10 directory
that builds ns-3 as well as other optional components such as NSC. waf is
the build framework for ns-3.10 itself.

Thanks Tom,

I passed --disable-nsc to build.py and it appears to have disabled the
NSC, but it looks like I have additional problems. The following is
the results:


$ ./build.py
# Skip NSC (by user request)
# Build NSC NS-3
Entering directory ‘./ns-3.10’
Note: configuring ns-3 without NSC
=> python waf configure –with-pybindgen ../pybindgen-0.15.0

I do not know what is the problem. Any help would be appreciated.

Does any one know what might be the problem?
