Mix GFortran/MSVC objects when linking: undefined reference to _chkstk

Question

Trying to compile Xfoil and plotlib

The fortran files are compiled with MinGW gfortran 4.5.0, and I compiled W32win.c with MSVC (2008/15.00).

During linking with GCC I receive error:

../plotlib/libPlt.a(W32win.o):(.text+0x1469): undefined reference to `_chkstk'
../plotlib/libPlt.a(W32win.o):(.text+0x1509): undefined reference to `_chkstk'

Any suggestions on how to resolve?

The reason I am trying to use MSVC, is that when I compiled plotlib with gcc only, the plot window does not operate properly, and displays only a black screen.

Answer 1

If you use the command-line MSVC compiler, cl.exe, use the option /Gs to prevent it from emitting the calls to _chkstk.

Otherwise that is probably a check-box in the project options part of the MSVC GUI.

Either way, recompile W32win.c with the needed compiler setting and you should be one step farther along your path.
