I can't figure out what's missing to make it make Magick++.

Can anyone help?

gcc -v

Add --disable-openmp to your configure script command line and reissue your make command. That may fix the problem.

Ok,

It seems like this is the real cause:

checking whether the compiler supports the std namespace... no
checking whether the compiler supports ISO C++ standard library... no

Do I need a newer version of gcc, rebuild it or a completely different compiler?

Thanks again.

Only Magick++ requires a C++ complier otherwise only C is needed. Try adding --disable-openmp --without-magick-plus-plus to your configure script command line and rebuild.

I want it to build it with Magick++

Magick++ requires a modern C++ compiler. You may need to upgrade your version of g++ so it meets the validation requirements of the configure script.
