adding c++ library giac/xcas to iOS project

Question

I've never included a C++ library in an iOS project before. Therefore I do not have so much experience with setting specific parameters. I want to use the giac CAS library from this site: https://www-fourier.ujf-grenoble.fr/~parisse/giac.html .

What have I done so far:

• copied libtommath files and dragged into my project
• copied all c++ and c header files from giac/src and dragged into my project
• copied config.h.iphone to config.h
• In build settings I changed C++ Standard Library to libstdc++ (GNU C++ standard library)
• In Header Search Paths and Library Search Paths I added gmp.h via the entry /usr/local/Cellar/gmp/6.2.1/include/**
• In Other Linker flags I added the entry "-lgmp"

Before trying to add an Objective-C++ class to expose functions from giac, I want to see if it could be built.

But I get the error "cstddef file not found" in file first.h Do I have to make other settings ?
