RE: "undefined reference" error message when using mkoctfile to create oct file

[Yan Zhang]

Thank you for the help. I tried different formats of the mkoctfile command and 
here are the messages I got (please note that a file "NewpDll.lib" is in the 
same folder as PowerMeter.cc):

>> mkoctfile ("PowerMeter.cc", "-l NewpDll.lib")
c:/users/yan/downloads/octave-4.0.0_0/octave-4.0.0/bin/../lib/gcc/i686-w64-mingw32/4.9.2/../../../../i686-w64-mingw32/bin/ld.exe:

wpDll.lib

octave for windows is built by GCC.

Your linker option is perhaps wrong.

-l NewpDll.lib might be modified to

-lNewpDll
