[gradsusr] Compiling grads from source

[Zilore Mumba]

Hello,
I am trying to compile grads from source according to guidance here
http://cola.gmu.edu/grads/gadoc/supplibs2.html. This is because I am
running 32 bit (ubuntu) and I do not see 32 bit binaries on the grads
download site.
I know building from source should be very complicated, considering the
number of supplementary libraries required.
Already I hit a snag compiling ncurses, the errors being
In file included from ../c++/cursesf.h:39:0,
                 from ../c++/cursesf.cc:35:
../c++/cursesp.h: In member function ‘T* NCursesUserPanel<T>::UserData()
const’:
../c++/cursesp.h:256:43: error: no matching function for call to
‘NCursesUserPanel<T>::get_user() const’
     return reinterpret_cast<T*>(get_user ());
                                           ^

         ^~~~~~~~

Makefile:319: recipe for target '../obj_s/cursesf.o' failed

make[1]: Leaving directory '/home/zmumba/grads/supplibs/src/ncurses-5.7/c++'
Makefile:98: recipe for target 'install' failed
make: *** [install] Error 2

Googling these errors does not seem to help so far.
I would appreciate if anyone has gone through this, resolved it and can
share

I have not gone beyond ncurses, thinking the libraries are to be built in
the order given on the website.
Thanks
