Message-ID:
Content-Type: text/plain; charset="utf-8"
My goal is to run an Octave file (an original .m script) from C++ written
in Qt.
Currently, I am using Octave v7.1.0 on Windows 10, and the C++17 code is
written in the Qt IDE v7.0.2. Additionally, my Build Environment has been
edited to include mkoctfile.exe for compiling purposes.
I have followed the descriptions found from the Octave user manual in
working with standalone programs, found here: Standalone Programs
first matrix example problem working fine as shown with the following
designed output,
11:51:02: Starting
C:\Users\berg\Documents\build-ForgeOctave-Desktop_Qt_6_3_1_MinGW_64_bit-Debug\debug\ForgeOctave.exe...FTH:
(2596): *** Fault tolerant heap shim applied to current process. This
is usually due to previous crashes. ***
Hello Octave world!

C:\Users\berg\Documents\build-ForgeOctave-Desktop_Qt_6_3_1_MinGW_64_bit-Debug\debug\ForgeOctave.exe

however the second example that requires the octave interpreter (which is
needed for calling external Octave .m files per Standalone Programs
following output:
11:54:52: Starting
C:\Users\berg\Documents\build-ForgeOctave-Desktop_Qt_6_3_1_MinGW_64_bit-Debug\debug\ForgeOctave.exe...FTH:

is usually due to previous crashes. ***error: ignoring const

C:\Users\berg\Documents\build-ForgeOctave-Desktop_Qt_6_3_1_MinGW_64_bit-Debug\debug\ForgeOctave.exe
exited with code 0
This leads me to believe that my issue is IDE-related. The exact issue
that I am having at the moment, is when I call the Octave interpreter
(octave::interpreter), it simply returns an error message of a crash.
My suspicion is that I may be missing a link to needed libraries or
need to further edit my Build Environment or Build Steps.
Below is my .pro file.
TEMPLATE = app
CONFIG += console c++17
CONFIG -= app_bundle
CONFIG += qt
LIBS+= -L C:\Users\berg\Desktop\Octave\octave-7.1.0-w64\mingw64\bin
-loctave-9 -LC:\Users\berg\Desktop\Octave\octave-7.1.0-w64\mingw64\lib\octave\7.1.0
-loctinterp -loctave
SOURCES += \
main.cpp
INCLUDEPATH += C:\Octave-7.1.0\mingw64\include\octave-7.1.0\octave
libmatrix.a
Does anyone have any idea how to solve this Octave interpreter problem or
have suggestions? Thanks!
