NS3 3.35 Installation error on MacOS Big Sur

[HongHsu Yen]

Hi,

When I install NS3 3.35 on MacOS Big Sur 11.6.1 by using the

./build.py --enable-examples --enable-tests

I have the following error message

======================================================================

../src/wifi/model/ht/ht-frame-exchange-manager.cc:900:57: error: 'value' is unavailable: introduced in macOS 10.13

              hdr.SetQosQueueSize (queueSizeForTid[tid].value ());

                                                        ^

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/v1/optional:953:27: note: 'value' has been explicitly marked unavailable here

    constexpr value_type& value() &

                          ^

1 error generated.

Waf: Leaving directory `/Users/honghsuyen/Downloads/ns-allinone-3.35/ns-3.35/build'

Build failed

 -> task in 'ns3-wifi' failed with exit status 1 (run with -v to display more information)

=======================================================================

Does anyone know how to solve this problem？Thank you very much.

Coincidentally, I turned on a new Apple M1 Mac Mini yesterday, upgraded
directly to Monterey, and installed command line tools.

I tried the following and did not have any compilation error:

$ mkdir temp && cd temp
$ curl -L https://www.nsnam.org/release/ns-allinone-3.35.tar.bz2 -o
ns-allinone-3.35.tar.bz2
$ tar xjf ns-allinone-3.35.tar.bz2
$ cd ns-allinone-3.35
$ ./build.py --enable-examples --enable-tests

and it built without a compilation error.

My Xcode command line tools version is:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 13.0.0.0.1.1627064638

My clang version is:

$ clang -v
Apple clang version 13.0.0 (clang-1300.0.27.3)


If these do not match for you, can you try an upgrade and try again?

Hi, Tom,

NS3 3.35 can be build after I upgrade to Monterey. Thanks a lot.

Another question is how to enable the GSL in NS3?

I install GSL by using  'brew install gsl' and it shows that gsl 2.7 is installed. But I configure again by using the './waf configure' and found out that GSL is still not enabled.

Do you know how to solve this problem.

Thanks again for your help.

You probably do not need GSL; it is only used for error rate models for
legacy Wi-Fi (802.11b 5.5 and 11 Mbps rates based on CCK modulation).
If you are not configuring 802.11b, then GSL won't be used.

If you want it, however, you will need to find out where homebrew
installed the pkg-config file (gsl.pc) and make sure that your
PKG_CONFIG_PATH environment variable is pointing to it. Waf is using
pkg-config to find the GSL libraries. This blog post has some more
information about PKG_CONFIG_PATH:

https://prateekvjoshi.com/2013/10/18/package-opencv-not-found-lets-find-it/

On Ubuntu Linux, GSL's pc file is at
/usr/lib/x86_64-linux-gnu/pkgconfig/gsl.pc.

Hi HongHsu,

I have the same error while installing ns3.35 on MacOs. Can you mention here how you resolved it?

Thanks!

Hi Shyam,
I have the same problem with ns-3.35.

I am already Monterey OS. 

I go back to ns-3.34 and then it build successfully.

Hey HongHsu 

I tried upgrading the command line tools but I am still getting the same error. do you have any idea how we could resolve it ?

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables 
package-id: com.apple.pkg.CLTools_Executables 
version: 13.0.0.0.1.1627064638 

My clang version is: 

$ clang -v 
Apple clang version 13.0.0 (clang-1300.0.27.3) 

[HongHsu Yen]

Hi,

I have no idea about your installation error.

My clang version is the same as you.

My command line tools information.

If you're using Python from a Conda environment, I was able to get around this by "/usr/bin/python"

./waf --python=/usr/bin/python configure --enable-examples --enable-tests

[Ophelia Doan]

I'm using Monetery OS and clang 12.0.0.

Can confirm going back to ns-3.34 instead of ns3.35 works.

[Tommaso Pecorella]

Downgrading ns-3 is always a bad idea... we're not squashing bugs and improving the models just for fun, isn't it ?

[Furkan Guvenc]

I have m1 with Monterey 12.1 and it throws the same error when building ns-3.35:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables

I opened an issue on the ns3 repo and they solved the problem
