[gdal-dev] compilation error - g++ unrecognized command line option

[Conrad Bielski]

Hi,

I couldn't find anything on this topic, so I hope that somebody has an answer to this issue. It might be Python related but I don't see the link.

So I get the following errors when running make:
g++: error: unrecognized command line option ‘-Wdate-time’
g++: error: unrecognized command line option ‘-Wnull-dereference’
g++: error: unrecognized command line option ‘-Wduplicated-cond’
g++: error: unrecognized command line option ‘-Wfloat-conversion’
make[1]: *** [cpl_conv.lo] Error 1
make[1]: Leaving directory `/home/ec2-user/tools/gdal-2.3.0/port'
make: *** [port-target] Error 2

The funny thing is that when running configure, I have the following results:
checking whether C compiler accepts -Wdate-time... yes
checking whether C compiler accepts -Wnull-dereference... yes
checking whether C compiler accepts -Wduplicated-cond... yes
checking whether C compiler accepts -Wfloat-conversion... yes

And I'm not sure where to look to fix this issue. I'm compiling on a Amazon Linux with gcc (GCC) 7.2.1 20170915 (Red Hat 7.2.1-2). The version of Python installed is Python 2.7.14.

Thanks in advance for your help,
Conrad
