Hi,
Now I should be ready to build NS-3. I execute the following commands:
This extracted NS-3's source code. Now I add the directory where xgcc and xg++ are to the PATH environment variable:
And try to configure and build NS-3:
I'm trying to install NS-3 in a server at my school.
The server has installed CentOS version 7.6.1810 and I don't have sudo privileges.
The server has installed gcc and g++ version 4.8.5-36. So, if I try to build NS-3.29 with those compilers it complains that it needs the minimum version 4.9.2. To solve this, I compiled from the sources gcc/g++ version 8.1.0. With this, I generated the executables xgcc and xg++ that are located in the directory /prime/apps/gcc/8.1.0/gcc.
So, I have the following directory hierarchy:
/prime/apps/gcc/8.1.0/gcc/
└ xgcc
└ xg++
Now I should be ready to build NS-3. I execute the following commands:
$ cd ~/NS3-Workspace
$ tar xjf ns-allinone-3.29.tar.bz2
$ cd ns-allinone-3.29/ns-3.29
$ PATH=$PATH":/prime/apps/gcc/8.1.0/gcc"
And try to configure and build NS-3:
$ CXX="xg++" CC="xgcc" ./waf configure --build-profile=optimized --enable-examples --enable-tests

I opened the build/config.log file to try to see what happened, and I noticed a lot of similar messages:
I don't know why this happens, because if I go to /usr/include I can see that most of the supposedly not found headers are there.
/usr/include/stdlib.h:32:10: fatal error: stddef.h: No such file or directory
#include <stddef.h>
...
/usr/include/signal.h:350:11: fatal error: stddef.h: No such file or directory
# include <stddef.h>
...
/usr/include/limits.h:124:26: error: no include path in which to search for limits.h
# include_next <limits.h>
...
(etc)I don't know why this happens, because if I go to /usr/include I can see that most of the supposedly not found headers are there.
I tried adding /usr/include explicitly to the PATH variable, but the result was the same: the headers are not found.
I continued with the building process to see what happened:
$ ./waf

I don't know for sure, but I think that for some unknown reason waf is not looking in /usr/include directory.
Does anyone know how to fix this issue I'm having?
Thanks in advance :)

Yes, 4.8 series or earlier will no longer work.
Although you are not an admin on this server, someone may have
installed a newer compiler via the software collections framework,
in which case it may exist on a different path. Check this path,
for instance:
/opt/rh/devtoolset-8/root/usr/bin/gccTo read more about it, please consult https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/
If it exists, you can try 'scl enable devtoolset-8 bash' and it
should extend your environment variables so that you can
preferentially use that alternative version.
Not all headers are in /usr/include; stddef.h typically is not.
I don't know whether your problems stem from not having done the
'make install' step on gcc.
Here is a wiki page that lists how to build a different version
of gcc and how to modify environment variables to get Waf to
default to it. Please let us know if it doesn't work for you:

Hi Tom, thank you for your reply.
I tried the two solutions that you proposed. Fortunately, one of them worked.

I checked the route /opt/rh/devtoolset-8/root/usr/bin/gcc and it doesn't exist, I think that the software collections framework is not installed in this server.
Yes! You are absolutely right. I forgot to execute make install. Now I've executed it and all my problems are gone.
I think that the guide you shared (https://www.nsnam.org/wiki/HOWTO_use_latest_gcc_release) is very helpful for all others who have the same problem because it resumes all the steps that involve the build and installing of gcc.
Thanks a lot :)
PS. I read all the sections of the manual to install GCC (https://gcc.gnu.org/install/) and executed the testing (https://gcc.gnu.org/install/test.html). I'm worried because it is showing some unexpected fails and some unexpected passes:
=== gcc Summary ===
# of expected passes 138393
# of unexpected failures 49
# of unexpected successes 20
# of expected failures 433
# of unsupported tests 2293Reply all
