errors with "mkoctfile convhulln.cc" in MSVC-Octave 3.0.3

[Fred Touwslager]

Recently a change has been made in the convhuln function to include calculation of the convex hull volume. Since I don't want to wait on a new MSVC-Octave release I have been trying to compile the function. However, without succes.

 

What I have done is following the instructions to make an .oct file in Octave as in this link: http://www.tatsuromatsuoka.com/octave/Eng/Win/msvcoct.html

I can run the oregonator.cc test as given in the web-page mentioned.

 

However, if I try to use the same procedure to make an .oct file from the convhulln.cc file I do get errors.

Convhulln.cc expects the presence of qhull/ghull_a.h. So I downloaded the qhull source package (from www.qhull.org) and placed it in a sub-directory of the directory in which convhulln.cc is present. Then all the files from qhull can be found.

However, mkoctfile then complains about 9 "unresolved external symbols", error LNK2019 e.g.:

 

convhulln.o : error LNK2019: unresolved external symbol _qh_memfreeshort referenced in function "class octave_value_list __cdecl FConvhulln(class octave_value_list const &,int)" (?Fconvhulln@@YA?AVoctave_value_list@@address@hidden@Z)

 

The last error is:

 

convhulln.oct : fatal error LNK1120: 9 unresolved externals

Anybody any idea about what to do to solve this issue?
