Hello everyone,

I am attempting to complete a parallel build of SU2 on my MacBook (macOS High Sierra Version 10.13.3). I have been following the steps detailed in the 'Build From Source" and "Parallel Build" tabs on the Docs page of the SU2 website.

I execute the following commands:

$ cd /Application/SU2-6.0.0/
$ ./configure --prefix=/Applications CXXFLAGS="-03" --enable-mpi --with-cc=/usr/local/bin/mpicc --with-cxx=/usr/local/bin/mpicxx --enable-tecio CPPFLAGS="-I/opt/X11/include"

However, the configure script encounters the following error:

configure: error: C++ compiler cannot create executables

I have attached a screen shot of the command terminal for clarity.

Below is the config.log file:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by SU2 configure 6.0.0, which was
generated by GNU Autoconf 2.69. Invocation command line was

$ ./configure --prefix=/Applications CXXFLAGS=-03 --enable-mpi --with-cc=/usr/local/bin/mpicc --with-cxx=/usr/local/bin/mpicxx --enable-tecio CPPFLAGS=-I/opt/X11/include

Any assistance in explaining/rectifying this error I am encountering would be greatly appreciated!

Many thanks,

Hi Christopher,

just change CXXFLAGS="-03" to CXXFLAGS="-O3" (so use the letter 'O' instead of the number '0')

Thank you for your reply Tim! I actually discovered the typo earlier today when I re-attempted the build and was planning to post a reply to this thread explaining my doofus mistake I appreciate you taking a moment to help me

Thank you,

Christopher
