[Ipopt] undefined reference to '_Ma27cd_'

Sure it is src/Interfence and libiopt.a ?
It should be src/Interface and libipopt.a.

Difficult to say.
Does ma27ad.f include all the subroutines ma27cd, ma27bd, ma27ad, ma27id?

Can you make sure that there was no problem in compiling ThirdParty/HSL.
In ThirdParty/HSL/.libs, there should be a file libcoinhsl.a.
The command "ar t libcoinhsl.a" should show you at least a ma27ad.o
The command "nm .libs/libcoinhsl.a  | grep -i ma27" should show the
symbol names as they are expected by IpMa27SolverInterface.o, i.e.,
_Ma27cd_, _Ma27bd_, ... with exact the same underlines ('_') and the
capitalization.

And if all this was ok, can you make sure whether libcoinhsl.a was
included into libipopt.a, maybe by recompiling libipopt.a and inspecting
the linker flags used.
