Thank you very much, Kostas and everyone!

I compiled the package, which was as easy as  "./configure CXX=/usr/local/bin/g++-10".

But now I get an error of course after "make" about finding libtool. I installed it with homebrew (/usr/local/bin/glibtool/). I can't  tell from --help of ./configure or make which flag I need to use to assign the right directory for libtool.

Thank you!

Dear Esin,

You got already some hints but, but try to address one issue at the time as they may appear. For now, it is clear that you have a very fundamental issue. The error message shows that you did not manage to use the correct C++ compiler or compiler version. What the configure script finds on your system is certainly not g++-10. I do not have experience with compiling on MacOS but, in general I would not recommend you to use aliases.
It is OK to use the CXX, CC and FC environment variables as Michel Furnie suggested. Just don't get into the mumps stuff that Michel discussed, yet. You are not close to that point yet. If you manage to compile GetFEM without mumps, then we can help you including mumps later.

Best regards

I have been trying to compile getfem 5.4.1 for a week now and I am out of ideas what to do, having read everything I can in the documentation and email list. I am a beginner in the command line usage and other developer environments. My experience for many years have been using MATLAB for any coding needs, so I know the problem I face must be very basic.

I used homebrew to update my g++ compiler to the latest version (located at /usr/local/bin/) and went through the steps of installing m4, automake,libtool, and python tools. I also did alias g++ g++-10. This is what I get when I run ./configure in the source file directory:

"checking whether the compiler recognizes the partial specialization syntax... yes

you are compiling GetFEM on a x86_64-apple-darwin19.6.0

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX10.15.sdk/usr/include/c++/4.2.1

Using the GNU g++ compiler version

checking whether g++ accepts -O3... no

checking whether g++ accepts -fmessage-length=0... no

checking whether g++ accepts -fvisibility-inlines-hidden... no

checking whether g++ accepts -ftemplate-depth-100... no

checking whether g++ accepts -std=c++14... no

checking whether g++ accepts -std=c++0x... no

configure: error: g++ do not support option -std=c++14. Update g++ to at least release 4.9"

It looks like there is some prefix configuration I get I don't know how to modify, but I am not sure if that is the problem. 

I appreciate any help!!

Thank  you
