Re: Mkoctfile cannot find -loctinterp and -loctave libraries

[Fávero Santos]

Hello, Tatsuro

Thanks for the help.

1. Changing arguments order resulted in the same error as before. Here follows the return from the cmd 

mkoctfile samples/c/analogin_sample.cpp -l lib/x86/dwf.lib

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -l-LC:\Octave\Octave-4.2.0\lib\octave\4.2.0

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -loctinterp

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -loctave

collect2.exe: error: ld returned 1 exit status

warning: mkoctfile: building exited with failure status

2. Running cmd the command with -v returns me the following:

mkoctfile -v -l lib/x86/dwf.lib samples/c/analogin_sample.cpp

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

warning: mkoctfile: building exited with failure status

3. Result using 64b library (that's actually the right library I should use, as my Windows is 64 b)

>> mkoctfile -l lib/x64/dwf.lib samples/c/analogin_sample.cpp

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -l-LC:\Octave\Octave-4.2.0\lib\octave\4.2.0

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -loctinterp

c:/octave/octave-4.2.0/bin/../lib/gcc/x86_64-w64-mingw32/4.9.4/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot

find -loctave

collect2.exe: error: ld returned 1 exit status

warning: mkoctfile: building exited with failure status

4. Strangely, linker cannot find library octave and library octinterp, even though if I issue 

>> dir C:\Octave\Octave-4.2.0\lib\octave\4.2.0

.                   liboctave.dll.a     liboctgui.dll.a     liboctinterp.dll.a  oct

..                  liboctave.la        liboctgui.la        liboctinterp.la     site

I can see those libraries.

Any thougts?

Thanks!

Sorry I have made a mistake.

-L.lib/x86 should be -L./lib/x86


Perhaps the library you want to link 32 bit while your octave 64 bit.
This may cause link error.

At that time use, 32bit version octave.
