Dear software developer,

I’m using Octave version 4.0.3 on Windows 8.1 (x64) and found the following
bug. 
I tried to program the example from appendix ‘A.1.9 Calling External Code
from Oct-Files’ of ‘octave.pdf’ manual. The direct usage of mkoctfile
command from the Octave-GUI don’t yields the expected result as described in
the manual. Thus, Octave should automate ‘this by providing the mkoctfile
command with which to build oct-files’. However this automation does not
work currently. That is the bug.
As solution I take ‘--verbose’ of the command and after that with the help
of Octave bash shell by ‘try and error’ I find out the correct input. You
can find it below:

$ gfortran -Wall -c  -O -mieee-fp   fortransub.f -o fortransub.o

$ g++ -Wall -c -I/scratch/jwe/mxe-octave/usr/i686-w64-mingw32/include 
-I/C/Octave/Octave-4.0.3/include/octave-4.0.3/octave/..  
-I/C/Octave/Octave-4.0.3/include/octave-4.0.3/octave
-I/C/Octave/Octave-4.0.3/include  -pthread  -mieee-fp -g -O2  fortrandemo.cc
-o fortrandemo.o

$ g++ -Wall -I/C/Octave/Octave-4.0.3/include/octave-4.0.3/octave/..
-I/C/Octave/Octave-4.0.3/include/octave-4.0.3/octave
-I/C/Octave/Octave-4.0.3/include -pthread -mieee-fp -g -O2 -shared
-Wl,--export-all-symbols -Wl,--enable-auto-import
-Wl,--enable-runtime-pseudo-reloc  -o fortrandemo.oct  fortransub.o
fortrandemo.o   -L/C/Octave/Octave-4.0.3/lib/octave/4.0.3
-L/C/Octave/Octave-4.0.3/lib -lliboctinterp -lliboctave 
-Wl,-rpath-link,/scratch/jwe/mxe-octave/usr/i686-w64-mingw32/lib
-L/scratch/jwe/mxe-octave/usr/i686-w64-mingw32/lib  -Wl,--export-all-symbols
–llibgfortran

As shown above there were two main problems. Firstly, the linking of the
correct libraries was erroneously: lliboctinterp, lliboctave (llibgfortran is
currently missing) and secondly, the backslash of the include paths was
wearisome, which I had to edit manually.

There is nothing more to be reported. I hope you will fix this bug, which
would be a great help for unprofessional programmer as me. 

Thank you for your effort!
